Where is LTC regarding block size : litecoin

Let's discuss some of the issues with Nano

Let's talk about some of Nano's biggest issues. I also made a video about this topic, available here: https://youtu.be/d9yb9ifurbg.
00:12 Spam
Issues
Potential Mitigations & Outstanding Issues
01:58 Privacy
Issues
  • Nano has no privacy. It is pseudonymous (like Bitcoin), not anonymous.
Potential Mitigations & Outstanding Issues & Outstanding Issues*
  • Second layer solutions like mixers can help, but some argue that isn't enough privacy.
  • The current protocol design + the computational overhead of privacy does not allow Nano to implement first layer privacy without compromising it's other features (fast, feeless, and scalable transactions).
02:56 Decentralization
Issues
  • Nano is currently not as decentralized as it could be. ~25% of the voting weight is held by Binance.
  • Users must choose representatives, and users don't always choose the best ones (or never choose).
Potential Mitigations & Outstanding Issues
  • Currently 4 unrelated parties (who all have a verifiable interest in keeping the network running) would have to work together to attack the network
  • Unlike Bitcoin, there is no mining or fees in Nano. This means that there is not a strong incentive for emergent centralization from profit maximization and economies of scale. We've seen this firsthand, as Nano's decentralization has increased over time.
  • Nano representative percentages are not that far off from Bitcoin mining pool percentages.
  • In Nano, voting weight can be remotely re-delegated to anyone at any time. This differs from Bitcoin, where consensus is controlled by miners and requires significant hardware investment.
  • The cost of a 51% attack scales with the market cap of Nano.
06:49 Marketing & adoption
Issues
  • The best technology doesn't always win. If no one knows about or uses Nano, it will die.
Potential Mitigations & Outstanding Issues
  • I would argue that the best technology typically does win, but it needs to be best in every way (price, speed, accessbility, etc). Nano is currently in a good place if you agree with that argument.
  • Bitcoin started small, and didn't spend money on marketing. It takes time to build a community.
  • The developers have said they will market more once the protocol is where they want it to be (v20 or v21?).
  • Community marketing initiatives have started to form organically (e.g. Twitter campaigns, YouTube ads, etc).
  • Marketing and adoption is a very difficult problem to solve, especially when you don't have first mover advantage or consistent cashflow.
08:07 Small developer fund
Issues
  • The developer fund only has 3 million NANO left (~$4MM), what happens after that?
Potential Mitigations & Outstanding Issues
  • The goal for Nano is to be an Internet RFC like TCP/IP or SMTP - development naturally slows down when the protocol is in a good place.
  • Nano development is completely open source, so anyone can participate. Multiple developers are now familiar with the Nano protocol.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
  • The developer fund was only ~5% of the supply - compare that to some of the other major cryptocurrencies.
10:08 Node incentives
Issues
  • There are no transaction fees, why would people run nodes to keep the network running?
Potential Mitigations & Outstanding Issues
  • The cost of consensus is so low in Nano that the benefits of the network itself are the incentive: decentralized money with 0 transaction fees that can be sent anywhere in the world nearly instantly. Similar to TCP/IP, email servers, and http servers. Just like Bitcoin full nodes.
  • Paying $50-$100 a month for a high-end node is a lot cheaper for merchants than paying 1-3% in total sales.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
11:58 No smart contracts
Issues
  • Nano doesn't support smart contracts.
Potential Mitigations & Outstanding Issues
  • Nano's sole goal is to be the most efficient peer-to-peer value transfer protocol possible. Adding smart contracts makes keeping Nano feeless, fast, and decentralized much more difficult.
  • Other solutions (e.g. Ethereum) exist for creating and enforcing smart contracts.
  • Code can still interact with Nano, but not on the first layer in a decentralized matter.
  • Real world smart contract adoption and usage is pretty limited at the moment, but that might not always be the case.
13:20 Price stability
Issues
  • Why would anyone accept or spend Nano if the price fluctuates so much?
  • Why wouldn't people just use a stablecoin version of Nano for sending and receiving money?
Potential Mitigations & Outstanding Issues
  • With good fiat gateways (stable, low fees, etc), you can always buy back the fiat equivalent of what you've spent.
  • The hope is that with enough adoption, people and businesses will eventually skip the fiat conversion and use Nano directly.
  • Because Nano is so fast, volatility is less of an issue. Transactions are confirmed in <10 seconds, and prices change less in that timeframe (vs 10 minutes to hours for Bitcoin).
  • Stablecoins reintroduce trust. Stable against what? Who controls the supply, and how do you get people to adopt them? What happens if the assets they're stable against fail? Nano is pure supply and demand.
  • With worldwide adoption, the market capitalization of Nano would be in the trillions. If that happens, even millions of dollars won't move the price significantly.
15:06 Deflation
Issues
  • Nano's current supply == max supply. Why would people spend Nano today if it could be worth more tomorrow?
  • What happens to principal representatives and voting weight as private keys are lost? How do you know keys are lost?
Potential Mitigations & Outstanding Issues
  • Nano is extremely divisible. 1 NANO is 1030 raw. Since there are no transaction fees, smaller and smaller amounts of Nano could be used to transact, even if the market cap reaches trillions.
  • People will always buy things they need (food, housing, etc).
  • I'm not sure what the plan is to adjust for lost keys. Probably requires more discussion.
Long-term Scalability
Issue
  • Current node software and hardware cannot handle thousands of TPS (low-end nodes fall behind at even 50 TPS).
  • The more representatives that exist, the more vote traffic is required (network bandwidth).
  • Low-end nodes currently slow down the network significantly. Principal representatives waste their resources constantly bootstrapping these weak nodes during network saturation.
Potential Mitigations & Outstanding Issues
  • Even as is, Nano can comfortably handle 50 TPS average - which is roughly the amount of transactions per day PayPal was doing in 2011 with nearly 100 million users.
  • Network bandwidth increases 50% a year.
  • There are some discussions of prioritizing bootstrapping by vote weight to limit the impact of weak nodes.
  • Since Nano uses an account balance system, pruning could drastically reduce storage requirements. You only need current state to keep the network running, not the full transaction history.
  • In the future, vote stapling could drastically reduce bandwidth usage by collecting all representative signatures up front and then only sharing that single aggregate signature.
  • Nano has no artificial protocol-based limits (e.g. block sizes or block times). It scales with hardware.
Obviously there is still a lot of work to be done in some areas, but overall I think Nano is a good place. For people that aren't Nano fans, what are your biggest concerns?

Recap of Binance English Kava AMA (May 2020)

This AMA was conducted within the Binance English Telegram channel prior to Kava's June 10th launch of its DeFi Lending Platform.

Q1:

Can you give us a little history of KAVA?

Q2:

Could you please tell me what KAVA cryptocurrency is? What problem does it solve?

  • Answer - KAVA is the staking, governance, and reserve asset of the Kava DeFi platform. KAVA is required by node operators to secure transactions on the blockchain. Additionally, when lending fees are paid, they are converted to Kava and burned reducing the overall supply of KAVA tokens. As more users use the Kava lending platform, KAVA should become more scarce overtime.

Q3:

What is the advantage of keeping the KAVA token for a long and short term?

  • Answer - In the short term, if you stake KAVA you can earn additional block rewards every day, block by block. This provides a nice steady return on the Kava usually in the range of 3-20% depending on the number of people staking.
  • We will be opening the gates of DeFi to many top tier assets such as BNB, XRP, ATOM, and BTC which have never been able to use lending, stablecoins, or other DeFi Services. If you are a KAVA hodler you can benefit from owning and having a stake in the network as we grow because as the network grows, Kava is burned and it becomes more scarce as a resource.

Q4:

Chainlink is KAVA’s partner, can you explain more about this partnership?

  • Answer - Yes, this is not the usual chainlink partnership where a blockchain consumes data from Chainlink’s oracle solution.
  • No oracle solution adequate for DeFi applications on Cosmos was available. For this reason, Kava has teamed up with Chainlink to bring its data and reliable oracle solution to the Cosmos ecosystem. Chainlink nodes now will be able to securely publish data directly on the Kava blockchain where it can be used or easily transported to other Cosmos-based blockchains and applications. Chainlink oracles on Kava utilize all the industry-leading technologies of Chainlink, while enabling more frequent price updates and improving the reach and distribution of where that data can be used.
  • Since Kava’s blockchain is built using Tendermint, Tendermint-based blockchains within the Cosmos ecosystem (Binance, Terra, OKChain, Cosmos Hub, Agoric, Aragon, and others) will now be able to retrieve market data such as cryptocurrency, FX, and commodity prices. For DEX’s like Binance this will enable them to create futures, options, and other derivative products they were not able to do so before.
  • TLDR: Kava + Chainlink Data creates the ideal hub for all blockchains and applications to get their DeFi services and Data, and as result makes Kava a natural hub for the growing Cosmos ecosystem.

Q5:

What is the KAVA CDP product? Do you have any exciting things down the pipeline that you can share?

  • Answer - First, let me clarify that CDP simply means “collateralized-debt-position” similar to CDOs that exist in the traditional finance world. What it means is a loan using collateral to back the loan.
  • Kava’s lending platform offers collateralized loans to users who have crypto. Getting a loan with Kava’s platform is great if you don’t want to sell your crypto position, but need short term cash for payments or if you want to use the loan to get a levered / margin position without going through KYC.
  • As for news! Kava’s lending platform is scheduled to officially launch on the mainnet June 10th.
  • At this time, DeFi will be made available to BNB for the first time ever. Also at this time, the Kava DeFi platform will be awarding the first users that have BNB extremely high rewards for being early adopters.
  • Each week, 74,000 KAVA will be given out to all the users who have taken out loans on Kava. Yes, you get free KAVA, for taking out a loan using BNB!
  • If you want to participate, you can learn more about how to do it here!
  • Medium

Q6:

Why should BNB users use KAVA’s lending platform and take out USDX? And how to mint USDX with BNB on KAVA CDP?

  • Answer - Free- maybe let's call it rewards for being good users 😉
  • The rewards are platform growth incentives so that we can grow the platform quickly.
  • Well at launch, definitely the KAVA rewards are a huge reason for BNB users to use it.
  • As for the product long-term, the major use case for our lending platform is to get a levered position without needing an exchange or to go through KYC.
  • How it works is that a BNB holder can deposit their BNB and take out USDX loans - this capital they will take and buy more BNB with it. Most people will use the loan this way to get 2-3x the original BNB amount. If the price goes up on BNB, they win 2-3x the gains!
  • Of course if the price goes down and they cannot repay their loan, the BNB collateral might get liquidated, so be careful, it works just like a margin trading account.

Q7:

Brian do you have any more information or links for our community about this?

Q8:

KAVA was initially planned to launch on Ripple network but later switched to Cosmos Tendermint Core. [email protected] is that something you see in Tendermint Core that is not available anywhere?

  • Answer - For clarification, Kava was never planned to be on Ripple. However, Ripple is a Kava investor, shareholder, and partner.
  • We selected the Cosmos-SDK featuring the Tendermint BFT consensus because during our past work with Ripple, MakerDao, ETH, and other layer 2 work we learned the value of “finality” of blockchains. For example, on ETH, the finality of blocks do not happen right away. You need to reach 15+ blocks to be confirmed on Ethereum to really know a transaction has passed. This results in really slow user experiences that aren’t acceptable in finance or any application really.
  • Tendermint solves this because it makes every transaction final and occur in seconds.
  • Additionally, we chose the Cosmos-SDK as the framework to build our stand alone blockchain, Kava because it allowed us to create our own security model and design which enables Kava as a DeFi platform responsible for millions of dollars of collateral to be very secure in a way we could net get if we built it on any other network.

Q9:

KAVA does cross-chain support. Compared to other DeFi platforms, KAVA offer collateralized loans and stable coins to users too. How will volatility be managed there with so many different collateral systems in CDP?

  • Answer - Volatility is an important consideration and accurate and timely price reference data is needed to make sure the system works.
  • All the collateral positions rely on price feeds from oracles to determine if they are safe or need to be liquidated. Kava has created a novel partnership with Chainlink, where Chainlink oracles that normally run on Ethereum, operate nodes directly on Kava where they can post prices. This Kava to avoid network congestion, high gas fees, and other less desirable issues found on Ethereum, while enabling the oracles with Kava’s fast blocktimes and finality so they can actually deliver price updates 10-20x more frequently than is possible elsewhere. This makes Kava’s price feed data very reliable.
  • In times of volatility, if liquidations occur, the Kava platform automatically auctions collateral off for USDX on the market and burns the USDX. This mechanism keeps the system balanced and USDX algorithmically stable and always fully collateralized by real assets.
  • And it does this transparently, unlike the real world CDOs which caused the world issues in 2008 due to the lack of transparency in their assets and risk.

Q10:

Recently, Binance has released a white paper on BSC, a Binance smart chain. So, what can I get by staking through Binance Coin BNB?

  • Answer - Yay for smart contracts!
  • What can we get by staking bnb?
  • Staking BNB on Kava, or depositing it in a CDP and creating USDX from it earns users KAVA in rewards everyweek. A lot of rewards. In addition, you get USDX to hold which also pays out a savings rate each block that is much better than say what USD in a checking account could do.

Q11:

Various platforms are in Ethereum. So why is Kava not at Ethereum?

  • Answer - I could speak about this for ages, but there is a reason for Ethereum being the home to many hacks and bugs.
  • Kava is not on ethereum because we couldn’t build our system there. The main reasons. as I have mentioned are:
  • (1) Ethereum has congestion, oracle issues, high fees, and slow block times.
  • (2) Ethereum’s open smart contracting system can do anything. This is great for building crypto kitties, but horrible for financial software as it makes all code have infinite attack vectors that hackers can use which are impossible to test for. We built our own chain so we could scope the code and limit what attack vectors are possible.
  • (3) Building in solidity, the language of Ethereum, is horrible. The development environment is bad, testnets don’t work, and many other things are painful. Kava is primarily built in GO which is far superior for financial applications in most respects.
  • (4) The future is Cosmos. Binance, Okchain, terra, Cosmos Hub(ATOM), and Kava all are created using the Cosmos-SDK framework. I believe this is the future and the blockchain developers are moving to this in mass. Over 110 projects now are building with the Cosmos-SDK.

Q12:

What are ways by which Kava project generates profit/revenue to maintain project. What is your revenue model?

  • Answer - Kava is a for-profit financial DAO with over 80 different businesses staking Kava and voting on its evolution. They want to see Kava succeed so they vote to fund operations and developments that drive user growth in Kava. Due to fees paid in Kava and the burning mechanism, as the system grows in users, the Kava supply decreases making those that hold Kava win due to scarcity.

Q13:

Lending/Borrowing has been introduced by Binance. How can this affect the Kava since people can directly borrow BUSD from Binance with BNB used as collateral than going to Kava?

  • Answer - Kava will be featured on Binance as well. The main benefit of Kava is that there is no counterparty. The capital is minted on demand not sourced from somewhere. Binance and other centralized parties on the otherhand need to find capital to provide loans, creating a cost of capital. Kava is much more efficient at providing capital and avoids a lot of regulator issues.
  • I'll add I think BUSD in the future might be usable for collateral to Kava's loans as well. It would be cool 🙂

Q14:

What's your opinions on Future of DeFi & DApps? Do you think that DeFi is the future of current Financial world? Also, How do you see the future of KAVA?

  • Answer - I believe Centralized Finance and the existing infrastructure has a place. It has a lot of issues that cause things like the 2008 crisis and the current insolvency issues that are happening across the world due to trust-based debt with no actual backers other than the people which end up bailing out banks and other financial institutions that have made poor decisions.
  • DeFi's future is bright because it solves this fundamental issue. It removes trust and adds transparency. Kava is right at the foundation for all of DeFi as things grow and mature.

Q15:

Recently, we have seen some big hacks in DeFi platforms. How will KAVA deal with these bad actors of crypto and what security measures have been taken by KAVA for the safety of users' funds?"

  • Answer - Unlike a lot of DeFi startups, we take things seriously. We don't ""move fast and break things"" as Mark Zuckerberg would say.
  • We do a thorough analysis before suggesting to deploy code. Our internal team works very hard to run tests and simulations, once it passes internally, we give it to 3rd party auditors who try and game it and break the code. If it passes there, we give the code to the community to review and vote into the mainnet. In this way, I’d estimate about 100+ people review our code and test it before it goes live and consumers can touch it. I don't know many other project teams that due things with such diligence.

Q16:

Binance for KAVA is a very valuable partner in terms of increasing the number of users, but what is KAVA ready to give equivalent to Binance users? What applications will be integrated into Binance to expand the ecosystem?

  • Answer - Kava gives the BNB users loans. It gives the DEX a stablecoin and the ability to offer margin products. Kava’s connection to binance chain and chainlink data also enables Binance DEX to offer trustless derivatives like options and futures products going forward.

Q17:

Cosmos has limitations on working with PoW coins. How do you technically solve the problem of implementing DeFi products for bitcoin?

  • Answer - Cosmos is great for hard-to-work-with blockchains like BTC. It's flexible in how you can construct bridges. For example, the validator set can have a multisig private key split up into pieces in order to create a trustless escrow and control of assets on other blockchains. In this way, we can create peg zones with Cosmos for the best assets in the world. Once a zone is established, it can be used on Kava and other Cosmos chains.

Q18:

USDX is currently a little-known stable coin. Do you plan to add it to the top exchanges with good liquidity, including Binance?

  • Answer - USDX will be growing quickly. We have a plan to have it listed and get liquidity across several known exchanges shortly after launch.

Q19:

There are several options for using USDX on the KAVA platform, one of which is Margin Trading / Leverage. Is this a selection function or a compulsory function? Wondering since there are some investors who don`t like margin. What is the level of leverage and how does a CDP auction work?

  • Answer - Using Kava for Margin trading is 100% optional. You can choose how you want to use the margin loan. You don’t have to spend the USDX unless you want to. It could be used for everyday payments as well in the case you simply don’t want to sell your underlying collateral. If you don’t want the risk, do small loans with lots of collateral.

Q20:

Will your team have a plan to implement the DAO module on your platform, as it provides autonomy, decentralization and transparency?

  • Answer - DAO - Kava is a for-profit DAO and it’s fully functional already. We have on-chain governance and have underwent several votes and evolutions you can look at. You actually can see some current voting processes taking place here: https://kava.mintscan.io/proposals
  • We recently implemented a cool feature called committees, which enables the DAO to elect a small group of experts to make decisions without needing a vote of the whole user base. This enables the experts to have control over a small portion of the protocol - such as monitoring the debt limit, fees, etc and enables Kava to operate faster and be more adaptable in volatile market conditions.

Q21:

How can we address the possible overloads and security threats caused by increased users in the DeFi scene?

  • Answer - Yes, this is a huge issue for Ethereum, MakerDAO and everyone in the space. I don’t see a bright future for DeFi on Etheruem unfortunately. You can’t have a blockchain do everything well. Tether alone congests most of Ethereum and makes oracle price feeds lag the market. This can cause liquidations that should not happen and real people will lose real funds. It’s a huge issue.
  • The hope is for a dedicated system like Kava to provide a better backbone for DeFi applications going forward.
  • I should point out that Kava is not just a MakerDao for Cosmos or a CDP for Bitcoin. Kava is designed to be a foundational layer for DeFi services that every new blockchain and application will need.
  • Every blockchain will need DeFi services like lending, stablecoins, and data and they need it to be very secure. Kava does all this with its cross-chain lending plarform, USDX stablecoin, and Chainlink data in an incredibly secure, but accessible manner.
  • In this way, Kava aims to connect and serve all the major cryptocurrency communities and build it’s place at the center, where every developer can get what they need to build financial applications of the future."

Q22:

What distinguishes Kava from your existing competitors like Syntetix?

  • Answer - Synthetix isn't really a competitor, but it is an interesting project in terms of mechanism design. We share a lot of common investors and have similar token economic ideas with them. The only blockchain project that could be is MakerDAO, but they can only work with ETH assets due to their design. We are focused on the major cap assets - BTC, BNB, XRP, ATOM and others have a much larger market than ETH to address. BTC is 10x the size alone. Currently no one serves them with DeFi. We’re going after this opportunity and believe it to be a huge one.

Q23:

Why is the KAVA coin not used for Mint, why am I asking that because I see it can also make the value of KAVA coins grow naturally?

  • Answer - Why is Kava not used as a collateral? Well, it could be I suppose. The community might vote for this in the near future if they want us to be like synthetix. It makes the Kava token more valuable and it will incentivize much more locked-up Kava reducing overall circulating supply which is fairly favorable. The main reason we have not done this yet is that we(Kava and its community) are still weighing the risks of doing this given that Kava also functions as a reserve asset. I think it's likely Kava gets added as collateral at some point, but it will likely have a high debt-collateral ratio to address the issues similar to Synthetix which is 750%.

Q24:

How do you prevent in a manipulated KAVA Mint just to take advantage of a token prize when minting?

  • Answer - Minting rewards and manipulation. We’ve thought of this. Each week, the blockchain counts all the blocks, counts how many people had a loan in that period, then takes the average loan amount over time to calculate the rewards. If you open and close a loan - you will get very little rewards. You only get a large reward if you keep the loan open the full period.

Q25:

Who are your oracle providers? Are you also an oracle provider?

  • Answer - Kava may run 1 oracle in the future, but we will always have many and be the minority. Most chainlink oracle node operators are large players in the space that run staking infrastructure companies like cosmostation, chainlayer, chorus one, figment networks, etc. Binance will also be one of our oracles.

Q26:

If we look at all the different types of DeFi products _(decentralized exchanges, stablecoins, atomic swaps, insurance products, loan platforms, trade financing platforms, custody platforms, and crowdfunding platforms) currently covering important areas of traditional finance...where does Kava fit in?

  • Answer - To make any interesting financial product work you need capital, a stable store of value, and price data. These are really hard to get on current blockchain environments. Kava provides all of these.

Q27:

Many people describe Kava as similar to Maker (MKR). How is Kava different? Why do you think Kava has more potential?

  • Answer - MakerDAO is a smart contract with a singular purpose, to serve ETH. It sadly inherited the problems of ethereum. Kava is designed from the ground up for security and interoperability. We are targeting bigger and better assets and have more capabilities to serve them with what their developers and ecosystem need.

Q28:

What is the uniqueness of KAVA project that cannot be found in other project that´s been released so far ?

  • Answer - Well in June 10th, we will be the first ever blockchain project to bring DeFi to another blockchain in a real way. BNB users will have loans, stablecoins, and much more.

Q29:

The gas fee is an issue for blockchain besides scalability. Does your Kava provide a solution for gas?

  • Answer - gas fees are very low on Kava, only high enough to prevent spam. We dont need high fees for TX because validators are paid in block rewards. Additionally, we dont have competing transactions from crypto-kitties or other non-financial applications. This leaves all of Kava's throughput 100% dedicated to scaling financial transactions.

Q30:

Kava project works on DeFi (Decentralized Finance) But what’s the benefits of Decentralized Financial system? What are the possibilities of DeFi over Centralized Finance system?

  • Answer - Open access, no need for trust, and no censorship by singular governments or parties. Kava is accessible anywhere in the world, by anyone.

Q31:

Data supplied by oracles are false at times, how do you prevent this? How reliable are data received by KAVA?

  • Answer - This is why using premium / credentialed APIs is important for oracles. These data sources tend to be more accurate and better managed. Wrong prices can happen - for liquidation systems like Kava, we factor this into our design by using an average of data overtime form all oracles as part of the calculation.

Q32:

Can anyone become a KAVA validator, or is it just an invitation from the project itself? What are the requirements for becoming a KAVA verifier?

  • Answer - Anyone can become a validator, but you will need to stake or have enough stake delegated to you from others to be in the top 100 validators to earn block rewards.

Q33:

DEFI PULSE said that a total of 902M is currently locked. According to you, how will this number change in the next few years, and how will KAVA position itself as the top player in this market segment?

  • Answer - DeFi will only grow through 2020. And likely grow massively.
  • All projects on DeFi pulse are ""ethereum"" based. Kava is going to shake the blockchain world in the next few weeks by being the first ""multi-chain"" project on DeFi pulse and by my estimations we should quickly surpass a lot of the projects on that list.

Q34:

I am an testnet minter and the process seem Simplified, now I want to know if minting of USDX will continue when you launch Mainnet and do you have plans to build your own KAVA WALLET for easy minting on your mainnet

  • Answer - Simple blockchain experience?! high praise! Yes the process will be the same. Kava will not provide interfaces or wallets. Kava Labs builds software for the blockchain, our community members like Cosmostation, Frontier, Trust Wallet build support for people to interact with it.

Q35:

What business plans does Kava have with Seoul (South Korea) after partnering with Cosmostation? Do you plan to expand your products beyond Asia? Have you thought about harnessing the potential of South America?

  • Answer - South Korea is a perfect market for Kava's DeFi. Regulations prohibit fiat-backed stablecoins and margin trading. Kava's platform uses crypto-backed stabvlecoins and can enable users to get loans to margin trade. I am looking forward to further developing the Korean market for Kava, working with close partners like Cosmostation and showing the world real use cases of DeFi.

Q36:

Thank you for taking the time to conduct this AMA. Do you have any parting words, and where can the people go to keep up with all of the new happenings regarding Kava Labs?

  • Answer - Thanks for all the awesome questions! Amazingly thoughtful!
  • I've been promising the world cross-chain DeFi since June of last year. The IEO and mainnet went live Nov 2019. It's been a year of hard work - but an industry first is coming on June 10th. I'm excited. I hope you guys are.
  • Thanks for having me, I hope you become a USDX minter and get KAVA rewards. And last but not least, I love Binance - it's Kava's first home and I'm really happy to open up DeFi to BNB first.
  • To keep up to date w/ all things Kava: Website - Telegram - Telegram for Kava Trading Chat - Twitter - Medium

Staking in Ethereum 2.0: when will it appear and how much can you earn on it?

Staking in Ethereum 2.0: when will it appear and how much can you earn on it?

Staking in Ethereum 2.0: when will it appear and how much can you earn on it?

Why coin staking will be added in Ethereum 2.0

A brief educational program for those who do not follow the update of the project of Vitalik Buterin. Ethereum has long been in need of updating, and the main problem of the network is scalability: the blockchain is overloaded, transactions are slowing down, and the cost of “gas” (transaction fees) is growing. If you do not update the consensus algorithm, then the network will someday cease to be operational. To avoid this, developers have been working for several years on moving the network from the PoW algorithm to state 2.0, running on PoS. This should make the network more scalable, faster and cheaper. In December last year, the first upgrade phase, Istanbul, was implemented in the network, and in April of this year, the Topaz test network with the possibility of staking was launched - the first users already earned 1%. In the PoS algorithm that Ethereum switches to, there is no mining, and validation occurs due to the delegation of user network coins to the masternodes. For the duration of the delegation, these coins are frozen, and for providing their funds for block validation, users receive a portion of the reward. This is staking - such a crypto-analogue of a bank deposit. There are several types of staking: with income from dividends or masternodes, but not the device’s power, as in PoW algorithms, but the number of miner coins is important in all of them. The more coins, the higher the income. For crypto investors, staking is an opportunity to receive passive income from blocked coins. It is assumed that the launch of staking:
  • Will make ETH mining more affordable, but less resource intensive;
  • Will make the network more secure and secure - attacks will become too expensive;
  • Will create an entirely new sector of steak infrastructure around the platform;
  • Provides increased scalability, which will create the opportunity for wider implementation of DeFi protocols;
  • And, most importantly, it will show that Ethereum is a developing project.

The first payments to stakeholders will be one to two years after the launch of the update

The minimum validator steak will be 32 ETN (≈$6092 for today). This is the minimum number of coins that an ETH holder must freeze in order to qualify for payments. Another prerequisite is not to disconnect your wallet from the network. If the user disconnects and goes into automatic mode, he loses his daily income. If at some point the steak drops below 16 ETH, the user will be deprived of the right to be a validator. The Ethereum network has to go through many more important stages before coin holders can make money on its storage. Collin Myers, the leader of the product strategy at the startup of the Ethereum developer ConsenSys, said that the genesis block of the new network will not be mined until the total amount of frozen funds reaches 524,000 ETN ($99.76 million at the time of publication). So many coins should be kept by 16,375 validators with a minimum deposit of 32 ETN. Until this moment, none of them will receive a percentage profit. Myers noted that this event is not tied to a clear time and depends on the activity of the community. All validators will have to freeze a rather significant amount for an indefinite period in the new network without confidence in the growth of the coin rate. It’s hard to say how many people there are. The developers believe that it will take 12−18 or even 24 months. According to the latest ConsenSys Codefi report, more than 65% of the 300 ETH owners surveyed plan to use the staking opportunity. This sample, of course, is not representative, but it can be assumed that most major coin holders will still be willing to take a chance.

How much can you earn on Ethereum staking

Developers have been arguing for a long time about what profitability should be among the validators of the Ethereum 2.0 network. The economic model of the network maintains an inflation rate below 1% and dynamically adjusts the reward scale for validators. The difficulty is not to overpay, but not to pay too little. Profitability will be variable, as it depends on the number and size of steaks, as well as other parameters. The fewer frozen coins and validators, the higher the yield, and vice versa. This is an easy way to motivate users to freeze ETN. According to the October calculations of Collin Myers, after the launch of Ethereum 2.0, validators will be able to receive from 4.6% to 10.3% per annum as a reward for their steak. At the summit, he clarified that the first time after the launch of the Genesis block, it can even reach 20.3%. But as the number of steaks grows, profitability will decline. So, with five million steaks, it drops to about 6.6%. The above numbers are not net returns. They do not include equipment and electricity costs. According to Myers, after the Genesis block, the costs of maintaining the validator node will be about 4.75% of the remuneration. They will continue to increase as the number of blocked coins increases, and with a five millionth steak, they will grow to about 14.7%. Myers emphasized that profitability will be higher for those who will work on their own equipment, rather than relying on cloud services. The latter, according to his calculations, at current prices can bring a loss of up to minus 15% per year. This, he believes, promotes true decentralization. At the end of April, Vitalik Buterin said that validators will be able to earn 5% per annum with a minimum stake of 32 ETH - 1.6 ETH per year, or $ 304 at the time of publication. However, given the cost of freezing funds, the real return will be at 0.8%.

How to calculate profitability from ETN staking

The easiest way to calculate the estimated return for Ethereum staking is to use a special calculator. For example, from the online services EthereumPrice or Stakingrewards. The service takes into account the latest indicators of network profitability, as well as additional characteristics: the time of operation of a node in the network, the price of a coin, the share of blocked ETNs and so on. Depending on these values, the profit of the validator can vary greatly. For example, you block 32 ETNs at today's coin price - $190, 1% of the coins are blocked, and the node works 99% of the time. According to the EthereumPrice calculator, in this case your yield will be 14.25% per annum, or 4.56 ETH.
Validator earnings from the example above for 10 years according to EthereumPrice.
If to change the data, you have the same steak, but the proportion of blocked coins is 10%. Now your annual yield is only 4.51%, or 1.44 ETH.
Validator earnings from the second example over 10 years according to EthereumPrice.
It is important that this is profitability excluding expenses. Real returns will be significantly lower and in the second case may be negative. In addition, you must consider the fluctuation of the course. Even with a yield of 14% per annum in ETN, dollar-denominated returns may be negative in a bear market.

When will the transition to Ethereum 2.0 start

Ben Edgington from Teku, the operator of Ethereum 2.0, at the last summit said that the transition to PoS could be launched in July this year. These deadlines, if there are no new delays, were also mentioned by experts of the BitMEX crypto exchange in their recent report on the transition of the Ethereum ecosystem to stage 2.0. However, on May 12, Vitalik Buterin denied the possibility of launching Ethereum 2.0 in July. The network is not yet ready and is unlikely to be launched before the end of the year. July 30 marks the 5th anniversary of the launch of Ethereum. Unfortunately, it seems that it will not be possible to start the update for the anniversary again. Full deployment of updates will consist of several stages. Phase 0. Beacon chain. The "zero" phase, which can be launched in July this year. In fact, it will only be a network test and PoS testing without economic activity, but it will use new ETN coins and the possibility of staking will appear. The "zero" phase will test the first layer of Ethereum 2.0 architecture - Lighthouse. This is the Ethereum 2.0 client in Rust, developed back in 2018. Phase 1. Sharding - rejection of full nodes in favor of load balancing between all network nodes (shards). This should increase network bandwidth and solve the scalability problem. This is the first full phase of Ethereum 2.0. It will initially be deployed with 64 shards. It is because of sharding that the transition of a network to a new state is so complicated - existing smart contracts cannot be transferred to a new network. Therefore, at first, perhaps several years, both networks will exist simultaneously. Phase 2. State execution. In this phase, various applications will work, and it will be possible to conclude smart contracts. This is a full-fledged working Ethereum 2.0 network. After the second phase, two networks will work in parallel - Ethereum and Ethereum 2.0. Coin holders will be able to transfer ETN from the first to the second without the ability to transfer them back. To stimulate network support, coin emissions in both networks will increase until they merge. Read more about the phases of transition to state 2.0 in the aforementioned BitMEX report.

How the upgrade to Ethereum 2.0 will affect the staking market and coin price

The transition of the second largest coin to PoS will dramatically increase the stake in the market. The deposit in 32 ETH is too large for most users. Therefore, we should expect an increase in offers for staking from the exchanges. So, the launch of such a service in November was announced by the largest Swiss crypto exchange Bitcoin Suisse. She will not have a minimum deposit, and the commission will be 15%. According to October estimates by Binance Research analysts, the transition of Ethereum to stage 2.0 can double the price of a coin and the stake of staking in the market, and it will also make ETH the most popular currency on the PoS algorithm. Adam Cochran, partner at MetaCartel Ventures DAO and developer of DuckDuckGo, argued in his blog that Ethereum's transition to state 2.0 would be the “biggest event” of the cryptocurrency market. He believes that a 3–5% return will attract the capital of large investors, and fear of lost profit (FOMO) among retail investors will push them to actively buy coins. The planned coin burning mechanism for each transaction will reduce the potential oversupply. However, BitMEX experts in the report mentioned above believe that updating the network will not be as important an event as it seems to many, and will not have a significant impact on the coin rate and the staking market. Initially, this will be more likely to test the PoS system, rather than a full-fledged network. There will be no economic activity and smart contracts, and interest for a steak will not be paid immediately. Therefore, most of the economic activity will continue to be concluded in the original Ethereum network, which will work in parallel with the new one. Analysts of the exchange emphasized that due to the addition of staking, the first time (short, in their opinion) a large number of ETNs will be blocked on the network. Most likely, this will limit the supply of coins and lead to higher prices. However, this can also release some of the ETNs blocked in smart contracts, and then the price will not rise. Moreover, the authors of the document are not sure that the demand for coins will be long-term and stable. For this to happen, PoS and sharding must prove that they work stably and provide the benefits for which the update was started. But, if this happens, the network is waiting for a wave of coins from the developers of smart contracts and DeFi protocols. In any case, quick changes should not be expected. A full transition to Ethereum 2.0 will take years and won’t be smooth - network failures are inevitable. We also believe that we should not rely on Ethereum staking as another panacea for all the problems of the coin and the market. Most likely, the transition of the network to PoS will not have a significant impact on the staking market, but may positively affect the price of the coin. However, relying on the ETN rally in anticipation of this is too optimistic.

What are Nano's biggest issues? Let's talk about it!

Let's talk about some of Nano's biggest issues. I also made a video about this topic, available here: https://youtu.be/d9yb9ifurbg.
00:12 Spam
Issues
Potential Mitigations & Outstanding Issues
01:58 Privacy
Issues
  • Nano has no privacy. It is pseudonymous (like Bitcoin), not anonymous.
Potential Mitigations & Outstanding Issues & Outstanding Issues*
  • Second layer solutions like mixers can help, but some argue that isn't enough privacy.
  • The current protocol design + the computational overhead of privacy does not allow Nano to implement first layer privacy without compromising it's other features (fast, feeless, and scalable transactions).
02:56 Decentralization
Issues
  • Nano is currently not as decentralized as it could be. ~25% of the voting weight is held by Binance.
  • Users must choose representatives, and users don't always choose the best ones (or never choose).
Potential Mitigations & Outstanding Issues
  • Currently 4 unrelated parties (who all have a verifiable interest in keeping the network running) would have to work together to attack the network
  • Unlike Bitcoin, there is no mining or fees in Nano. This means that there is not a strong incentive for emergent centralization from profit maximization and economies of scale. We've seen this firsthand, as Nano's decentralization has increased over time.
  • Nano representative percentages are not that far off from Bitcoin mining pool percentages.
  • In Nano, voting weight can be remotely re-delegated to anyone at any time. This differs from Bitcoin, where consensus is controlled by miners and requires significant hardware investment.
  • The cost of a 51% attack scales with the market cap of Nano.
06:49 Marketing & adoption
Issues
  • The best technology doesn't always win. If no one knows about or uses Nano, it will die.
Potential Mitigations & Outstanding Issues
  • I would argue that the best technology typically does win, but it needs to be best in every way (price, speed, accessbility, etc). Nano is currently in a good place if you agree with that argument.
  • Bitcoin started small, and didn't spend money on marketing. It takes time to build a community.
  • The developers have said they will market more once the protocol is where they want it to be (v20 or v21?).
  • Community marketing initiatives have started to form organically (e.g. Twitter campaigns, YouTube ads, etc).
  • Marketing and adoption is a very difficult problem to solve, especially when you don't have first mover advantage or consistent cashflow.
08:07 Small developer fund
Issues
  • The developer fund only has 3 million NANO left (~$4MM), what happens after that?
Potential Mitigations & Outstanding Issues
  • The goal for Nano is to be an Internet RFC like TCP/IP or SMTP - development naturally slows down when the protocol is in a good place.
  • Nano development is completely open source, so anyone can participate. Multiple developers are now familiar with the Nano protocol.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
  • The developer fund was only ~5% of the supply - compare that to some of the other major cryptocurrencies.
10:08 Node incentives
Issues
  • There are no transaction fees, why would people run nodes to keep the network running?
Potential Mitigations & Outstanding Issues
  • The cost of consensus is so low in Nano that the benefits of the network itself are the incentive: decentralized money with 0 transaction fees that can be sent anywhere in the world nearly instantly.
  • Paying $50-$100 a month for a high-end node is a lot cheaper for merchants than paying 1-3% in total sales.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
11:58 No smart contracts
Issues
  • Nano doesn't support smart contracts.
Potential Mitigations & Outstanding Issues
  • Nano's sole goal is to be the most efficient peer-to-peer value transfer protocol possible. Adding smart contracts makes keeping Nano feeless, fast, and decentralized much more difficult.
  • Other solutions (e.g. Ethereum) exist for creating and enforcing smart contracts.
  • Code can still interact with Nano, but not on the first layer in a decentralized matter.
  • Real world smart contract adoption and usage is pretty limited at the moment, but that might not always be the case.
13:20 Price stability
Issues
  • Why would anyone accept or spend Nano if the price fluctuates so much?
  • Why wouldn't people just use a stablecoin version of Nano for sending and receiving money?
Potential Mitigations & Outstanding Issues
  • With good fiat gateways (stable, low fees, etc), you can always buy back the fiat equivalent of what you've spent.
  • The hope is that with enough adoption, people and businesses will eventually skip the fiat conversion and use Nano directly.
  • Because Nano is so fast, volatility is less of an issue. Transactions are confirmed in <10 seconds, and prices change less in that timeframe (vs 10 minutes to hours for Bitcoin).
  • Stablecoins reintroduce trust. Stable against what? Who controls the supply, and how do you get people to adopt them? What happens if the assets they're stable against fail? Nano is pure supply and demand.
  • With worldwide adoption, the market capitalization of Nano would be in the trillions. If that happens, even millions of dollars won't move the price significantly.
15:06 Deflation
Issues
  • Nano's current supply == max supply. Why would people spend Nano today if it could be worth more tomorrow?
  • What happens to principal representatives and voting weight as private keys are lost? How do you know keys are lost?
Potential Mitigations & Outstanding Issues
  • Nano is extremely divisible. 1 NANO is 1030 raw. Since there are no transaction fees, smaller and smaller amounts of Nano could be used to transact, even if the market cap reaches trillions.
  • People will always buy things they need (food, housing, etc).
  • I'm not sure what the plan is to adjust for lost keys. Probably requires more discussion.
Long-term Scalability
Issue
  • Current node software and hardware cannot handle thousands of TPS (low-end nodes fall behind at even 50 TPS).
  • The more representatives that exist, the more vote traffic is required (network bandwidth).
  • Low-end nodes currently slow down the network significantly. Principal representatives waste their resources constantly bootstrapping these weak nodes during network saturation.
Potential Mitigations & Outstanding Issues
  • Even as is, Nano can comfortably handle 50 TPS average - which is roughly the amount of transactions per day PayPal was doing in 2011 with nearly 100 million users.
  • Network bandwidth increases 50% a year.
  • There are some discussions of prioritizing bootstrapping by vote weight to limit the impact of weak nodes.
  • Since Nano uses an account balance system, pruning could drastically reduce storage requirements. You only need current state to keep the network running, not the full transaction history.
  • In the future, vote stapling could drastically reduce bandwidth usage by collecting all representative signatures up front and then only sharing that single aggregate signature.
  • Nano has no artificial protocol-based limits (e.g. block sizes or block times). It scales with hardware.

Technical: A Brief History of Payment Channels: from Satoshi to Lightning Network

Who cares about political tweets from some random country's president when payment channels are a much more interesting and are actually capable of carrying value?
So let's have a short history of various payment channel techs!

Generation 0: Satoshi's Broken nSequence Channels

Because Satoshi's Vision included payment channels, except his implementation sucked so hard we had to go fix it and added RBF as a by-product.
Originally, the plan for nSequence was that mempools would replace any transaction spending certain inputs with another transaction spending the same inputs, but only if the nSequence field of the replacement was larger.
Since 0xFFFFFFFF was the highest value that nSequence could get, this would mark a transaction as "final" and not replaceable on the mempool anymore.
In fact, this "nSequence channel" I will describe is the reason why we have this weird rule about nLockTime and nSequence. nLockTime actually only works if nSequence is not 0xFFFFFFFF i.e. final. If nSequence is 0xFFFFFFFF then nLockTime is ignored, because this if the "final" version of the transaction.
So what you'd do would be something like this:
  1. You go to a bar and promise the bartender to pay by the time the bar closes. Because this is the Bitcoin universe, time is measured in blockheight, so the closing time of the bar is indicated as some future blockheight.
  2. For your first drink, you'd make a transaction paying to the bartender for that drink, paying from some coins you have. The transaction has an nLockTime equal to the closing time of the bar, and a starting nSequence of 0. You hand over the transaction and the bartender hands you your drink.
  3. For your succeeding drink, you'd remake the same transaction, adding the payment for that drink to the transaction output that goes to the bartender (so that output keeps getting larger, by the amount of payment), and having an nSequence that is one higher than the previous one.
  4. Eventually you have to stop drinking. It comes down to one of two possibilities:
    • You drink until the bar closes. Since it is now the nLockTime indicated in the transaction, the bartender is able to broadcast the latest transaction and tells the bouncers to kick you out of the bar.
    • You wisely consider the state of your liver. So you re-sign the last transaction with a "final" nSequence of 0xFFFFFFFF i.e. the maximum possible value it can have. This allows the bartender to get his or her funds immediately (nLockTime is ignored if nSequence is 0xFFFFFFFF), so he or she tells the bouncers to let you out of the bar.
Now that of course is a payment channel. Individual payments (purchases of alcohol, so I guess buying coffee is not in scope for payment channels). Closing is done by creating a "final" transaction that is the sum of the individual payments. Sure there's no routing and channels are unidirectional and channels have a maximum lifetime but give Satoshi a break, he was also busy inventing Bitcoin at the time.
Now if you noticed I called this kind of payment channel "broken". This is because the mempool rules are not consensus rules, and cannot be validated (nothing about the mempool can be validated onchain: I sigh every time somebody proposes "let's make block size dependent on mempool size", mempool state cannot be validated by onchain data). Fullnodes can't see all of the transactions you signed, and then validate that the final one with the maximum nSequence is the one that actually is used onchain. So you can do the below:
  1. Become friends with Jihan Wu, because he owns >51% of the mining hashrate (he totally reorged Bitcoin to reverse the Binance hack right?).
  2. Slip Jihan Wu some of the more interesting drinks you're ordering as an incentive to cooperate with you. So say you end up ordering 100 drinks, you split it with Jihan Wu and give him 50 of the drinks.
  3. When the bar closes, Jihan Wu quickly calls his mining rig and tells them to mine the version of your transaction with nSequence 0. You know, that first one where you pay for only one drink.
  4. Because fullnodes cannot validate nSequence, they'll accept even the nSequence=0 version and confirm it, immutably adding you paying for a single alcoholic drink to the blockchain.
  5. The bartender, pissed at being cheated, takes out a shotgun from under the bar and shoots at you and Jihan Wu.
  6. Jihan Wu uses his mystical chi powers (actually the combined exhaust from all of his mining rigs) to slow down the shotgun pellets, making them hit you as softly as petals drifting in the wind.
  7. The bartender mutters some words, clothes ripping apart as he or she (hard to believe it could be a she but hey) turns into a bear, ready to maul you for cheating him or her of the payment for all the 100 drinks you ordered from him or her.
  8. Steely-eyed, you stand in front of the bartender-turned-bear, daring him to touch you. You've watched Revenant, you know Leonardo di Caprio could survive a bear mauling, and if some posh actor can survive that, you know you can too. You make a pose. "Drunken troll logic attack!"
  9. I think I got sidetracked here.
Lessons learned?

Spilman Channels

Incentive-compatible time-limited unidirectional channel; or, Satoshi's Vision, Fixed (if transaction malleability hadn't been a problem, that is).
Now, we know the bartender will turn into a bear and maul you if you try to cheat the payment channel, and now that we've revealed you're good friends with Jihan Wu, the bartender will no longer accept a payment channel scheme that lets one you cooperate with a miner to cheat the bartender.
Fortunately, Jeremy Spilman proposed a better way that would not let you cheat the bartender.
First, you and the bartender perform this ritual:
  1. You get some funds and create a transaction that pays to a 2-of-2 multisig between you and the bartender. You don't broadcast this yet: you just sign it and get its txid.
  2. You create another transaction that spends the above transaction. This transaction (the "backoff") has an nLockTime equal to the closing time of the bar, plus one block. You sign it and give this backoff transaction (but not the above transaction) to the bartender.
  3. The bartender signs the backoff and gives it back to you. It is now valid since it's spending a 2-of-2 of you and the bartender, and both of you have signed the backoff transaction.
  4. Now you broadcast the first transaction onchain. You and the bartender wait for it to be deeply confirmed, then you can start ordering.
The above is probably vaguely familiar to LN users. It's the funding process of payment channels! The first transaction, the one that pays to a 2-of-2 multisig, is the funding transaction that backs the payment channel funds.
So now you start ordering in this way:
  1. For your first drink, you create a transaction spending the funding transaction output and sending the price of the drink to the bartender, with the rest returning to you.
  2. You sign the transaction and pass it to the bartender, who serves your first drink.
  3. For your succeeding drinks, you recreate the same transaction, adding the price of the new drink to the sum that goes to the bartender and reducing the money returned to you. You sign the transaction and give it to the bartender, who serves you your next drink.
  4. At the end:
    • If the bar closing time is reached, the bartender signs the latest transaction, completing the needed 2-of-2 signatures and broadcasting this to the Bitcoin network. Since the backoff transaction is the closing time + 1, it can't get used at closing time.
    • If you decide you want to leave early because your liver is crying, you just tell the bartender to go ahead and close the channel (which the bartender can do at any time by just signing and broadcasting the latest transaction: the bartender won't do that because he or she is hoping you'll stay and drink more).
    • If you ended up just hanging around the bar and never ordering, then at closing time + 1 you broadcast the backoff transaction and get your funds back in full.
Now, even if you pass 50 drinks to Jihan Wu, you can't give him the first transaction (the one which pays for only one drink) and ask him to mine it: it's spending a 2-of-2 and the copy you have only contains your own signature. You need the bartender's signature to make it valid, but he or she sure as hell isn't going to cooperate in something that would lose him or her money, so a signature from the bartender validating old state where he or she gets paid less isn't going to happen.
So, problem solved, right? Right? Okay, let's try it. So you get your funds, put them in a funding tx, get the backoff tx, confirm the funding tx...
Once the funding transaction confirms deeply, the bartender laughs uproariously. He or she summons the bouncers, who surround you menacingly.
"I'm refusing service to you," the bartender says.
"Fine," you say. "I was leaving anyway;" You smirk. "I'll get back my money with the backoff transaction, and posting about your poor service on reddit so you get negative karma, so there!"
"Not so fast," the bartender says. His or her voice chills your bones. It looks like your exploitation of the Satoshi nSequence payment channel is still fresh in his or her mind. "Look at the txid of the funding transaction that got confirmed."
"What about it?" you ask nonchalantly, as you flip open your desktop computer and open a reputable blockchain explorer.
What you see shocks you.
"What the --- the txid is different! You--- you changed my signature?? But how? I put the only copy of my private key in a sealed envelope in a cast-iron box inside a safe buried in the Gobi desert protected by a clan of nomads who have dedicated their lives and their childrens' lives to keeping my private key safe in perpetuity!"
"Didn't you know?" the bartender asks. "The components of the signature are just very large numbers. The sign of one of the signature components can be changed, from positive to negative, or negative to positive, and the signature will remain valid. Anyone can do that, even if they don't know the private key. But because Bitcoin includes the signatures in the transaction when it's generating the txid, this little change also changes the txid." He or she chuckles. "They say they'll fix it by separating the signatures from the transaction body. They're saying that these kinds of signature malleability won't affect transaction ids anymore after they do this, but I bet I can get my good friend Jihan Wu to delay this 'SepSig' plan for a good while yet. Friendly guy, this Jihan Wu, it turns out all I had to do was slip him 51 drinks and he was willing to mine a tx with the signature signs flipped." His or her grin widens. "I'm afraid your backoff transaction won't work anymore, since it spends a txid that is not existent and will never be confirmed. So here's the deal. You pay me 99% of the funds in the funding transaction, in exchange for me signing the transaction that spends with the txid that you see onchain. Refuse, and you lose 100% of the funds and every other HODLer, including me, benefits from the reduction in coin supply. Accept, and you get to keep 1%. I lose nothing if you refuse, so I won't care if you do, but consider the difference of getting zilch vs. getting 1% of your funds." His or her eyes glow. "GENUFLECT RIGHT NOW."
Lesson learned?

CLTV-protected Spilman Channels

Using CLTV for the backoff branch.
This variation is simply Spilman channels, but with the backoff transaction replaced with a backoff branch in the SCRIPT you pay to. It only became possible after OP_CHECKLOCKTIMEVERIFY (CLTV) was enabled in 2015.
Now as we saw in the Spilman Channels discussion, transaction malleability means that any pre-signed offchain transaction can easily be invalidated by flipping the sign of the signature of the funding transaction while the funding transaction is not yet confirmed.
This can be avoided by simply putting any special requirements into an explicit branch of the Bitcoin SCRIPT. Now, the backoff branch is supposed to create a maximum lifetime for the payment channel, and prior to the introduction of OP_CHECKLOCKTIMEVERIFY this could only be done by having a pre-signed nLockTime transaction.
With CLTV, however, we can now make the branches explicit in the SCRIPT that the funding transaction pays to.
Instead of paying to a 2-of-2 in order to set up the funding transaction, you pay to a SCRIPT which is basically "2-of-2, OR this singlesig after a specified lock time".
With this, there is no backoff transaction that is pre-signed and which refers to a specific txid. Instead, you can create the backoff transaction later, using whatever txid the funding transaction ends up being confirmed under. Since the funding transaction is immutable once confirmed, it is no longer possible to change the txid afterwards.

Todd Micropayment Networks

The old hub-spoke model (that isn't how LN today actually works).
One of the more direct predecessors of the Lightning Network was the hub-spoke model discussed by Peter Todd. In this model, instead of payers directly having channels to payees, payers and payees connect to a central hub server. This allows any payer to pay any payee, using the same channel for every payee on the hub. Similarly, this allows any payee to receive from any payer, using the same channel.
Remember from the above Spilman example? When you open a channel to the bartender, you have to wait around for the funding tx to confirm. This will take an hour at best. Now consider that you have to make channels for everyone you want to pay to. That's not very scalable.
So the Todd hub-spoke model has a central "clearing house" that transport money from payers to payees. The "Moonbeam" project takes this model. Of course, this reveals to the hub who the payer and payee are, and thus the hub can potentially censor transactions. Generally, though, it was considered that a hub would more efficiently censor by just not maintaining a channel with the payer or payee that it wants to censor (since the money it owned in the channel would just be locked uselessly if the hub won't process payments to/from the censored user).
In any case, the ability of the central hub to monitor payments means that it can surveill the payer and payee, and then sell this private transactional data to third parties. This loss of privacy would be intolerable today.
Peter Todd also proposed that there might be multiple hubs that could transport funds to each other on behalf of their users, providing somewhat better privacy.
Another point of note is that at the time such networks were proposed, only unidirectional (Spilman) channels were available. Thus, while one could be a payer, or payee, you would have to use separate channels for your income versus for your spending. Worse, if you wanted to transfer money from your income channel to your spending channel, you had to close both and reshuffle the money between them, both onchain activities.

Poon-Dryja Lightning Network

Bidirectional two-participant channels.
The Poon-Dryja channel mechanism has two important properties:
Both the original Satoshi and the two Spilman variants are unidirectional: there is a payer and a payee, and if the payee wants to do a refund, or wants to pay for a different service or product the payer is providing, then they can't use the same unidirectional channel.
The Poon-Dryjam mechanism allows channels, however, to be bidirectional instead: you are not a payer or a payee on the channel, you can receive or send at any time as long as both you and the channel counterparty are online.
Further, unlike either of the Spilman variants, there is no time limit for the lifetime of a channel. Instead, you can keep the channel open for as long as you want.
Both properties, together, form a very powerful scaling property that I believe most people have not appreciated. With unidirectional channels, as mentioned before, if you both earn and spend over the same network of payment channels, you would have separate channels for earning and spending. You would then need to perform onchain operations to "reverse" the directions of your channels periodically. Secondly, since Spilman channels have a fixed lifetime, even if you never used either channel, you would have to periodically "refresh" it by closing it and reopening.
With bidirectional, indefinite-lifetime channels, you may instead open some channels when you first begin managing your own money, then close them only after your lawyers have executed your last will and testament on how the money in your channels get divided up to your heirs: that's just two onchain transactions in your entire lifetime. That is the potentially very powerful scaling property that bidirectional, indefinite-lifetime channels allow.
I won't discuss the transaction structure needed for Poon-Dryja bidirectional channels --- it's complicated and you can easily get explanations with cute graphics elsewhere.
There is a weakness of Poon-Dryja that people tend to gloss over (because it was fixed very well by RustyReddit):
Another thing I want to emphasize is that while the Lightning Network paper and many of the earlier presentations developed from the old Peter Todd hub-and-spoke model, the modern Lightning Network takes the logical conclusion of removing a strict separation between "hubs" and "spokes". Any node on the Lightning Network can very well work as a hub for any other node. Thus, while you might operate as "mostly a payer", "mostly a forwarding node", "mostly a payee", you still end up being at least partially a forwarding node ("hub") on the network, at least part of the time. This greatly reduces the problems of privacy inherent in having only a few hub nodes: forwarding nodes cannot get significantly useful data from the payments passing through them, because the distance between the payer and the payee can be so large that it would be likely that the ultimate payer and the ultimate payee could be anyone on the Lightning Network.

After LN, there's also the Decker-Wattenhofer Duplex Micropayment Channels (DMC). This post is long enough as-is, LOL. But for now, it uses a novel "decrementing nSequence channel", using the new relative-timelock semantics of nSequence (not the broken one originally by Satoshi). It actually uses multiple such "decrementing nSequence" constructs, terminating in a pair of Spilman channels, one in both directions (thus "duplex"). Maybe I'll discuss it some other time.
The realization that channel constructions could actually hold more channel constructions inside them (the way the Decker-Wattenhofer puts a pair of Spilman channels inside a series of "decrementing nSequence channels") lead to the further thought behind Burchert-Decker-Wattenhofer channel factories. Basically, you could host multiple two-participant channel constructs inside a larger multiparticipant "channel" construct (i.e. host multiple channels inside a factory).
Further, we have the Decker-Russell-Osuntokun or "eltoo" construction. I'd argue that this is "nSequence done right". I'll write more about this later, because this post is long enough.

[Part 1] KAVA Historical AMA Tracker! (Questions & Answers)

ATTN: These AMA questions are from Autumn 2019 - before the official launch of the Kava Mainnet, and it's fungible Kava Token.
These questions may no longer be relevant to the current Kava landscape, however, they do provide important historical background on the early origins of Kava Labs.
Please note, that there are several repeat questions/answers.

Q1:

Kava is a decentralized DEFI project, why did you implement the countries restrictions to run the node? Will there be such restrictions by the time of the mainnet?

Q2:

According to the project description it has been indicated that staking reward (in KAVA tokens) varies from 3 to 20% per annum. But how will you fight with inflation?

We all know how altcoins prices are falling, and their bottom is not visible. And in fact, we can get an increase in the number of tokens for staking, but not an increase in the price of the token itself and become a long-term investor.

  • Answer: Kava is both inflationary with block rewards, but deflationary when we burn CDP fees. Only stakers who bond their Kava receive inflationary rewards - users and traders on exchanges do not get this. In this way, rewards are inflated, but given to stakers and removed value from the traders who are speculating like a tax. The Deflationary structure of fees should help counterbalance the price drops from inflation if any. In the long-term as more CDPs are used, Kava should be a deflationary asset by design if all things go well

Q3:

In your allocation it is indicated that 28.48% of the tokens are in the "Token treasury" - where will these tokens be directed?

  • Answer: Investors in financing rounds prior to the IEO have entered into long-term lock-up agreements in-line with their belief in Kava’s exciting long-term growth potential and to allow the projects token price to find stability. Following the IEO, the only tokens in circulation will be those sold through the IEO on Binance and the initial Treasury tokens released.
  • No private sale investor tokens are in circulation until the initial release at the end of Q1 2020 and then gradually over the [36] months The initial Treasury tokens in circulation will be used for a mixture of ecosystem grants, the expenses associated with the IEO as well as initial market making requirements as is typical with a listing of this size. Kava remains well financed to execute our roadmap following the IEO and do not envisage any need for any material financings or token sales for the foreseeable future.

Q4:

Such a platform (with loans and stable coins) is just the beginning since these aspects are a small part of many Defi components. Will your team have a plan to implement other functions, such as derivatives, the dex platform once the platform is successfully launched?

  • Answer: We believe Kava is the foundation for many future defi products. We need stable coins, oracles, and other infrastructure first that Kava provides. Once we have that, we can apply these to derivatives and other synthetics more easily. For example, we can use the price feeds and USDX to enable users to place 100x leverage bets with each other. If they both lock funds into payment channels, then they can use a smart contract based on the price feed to do the 100x trade/bet automatically without counter party risk. In this way, Kava can expand its financial product offerings far beyond loans and stable coins in the future.

Q5:

There are several options for using USDX on the KAVA platform, one of which is Margin Trading / Leverage. Is this a selection function or a compulsory function? Wondering since there are some investors who don`t like margin. What is the level of leverage and how does a CDP auction work?

  • Answer: This is a good #Q . Kava simply provides loans to users in USDX stable coins. What the users do is completely up to them. They can use the loans for everyday payments if they like. Leverage and hedging are just the main use cases we foresee - there are many ways people can use the CDP platform and USDX.

Q6:

Most credit platforms do not work well in the current market. What will you do to attract more people to use your platform and the services you provide? Thank you

  • Answer: Most credit platforms do not work well in the current market? I think that isn't correct at least for DeFi. Even in the bear market, MakerDao and Compound saw good user growth. Regardless, our efforts at Kava to build the market are fairly product and BD focused. 1) we build more integrations of assets and expand financial services to attract new communities and users. 2) we focus on building partnerships with high quality teams to promote and build Kava's core user base. Kava is just the developer. Our great partners like Ripple, Stakewith.Us, P2P, Binance - they have the real users that demand Kava. They are like our system integrators that package Kava up nicely and present it to their users. In order to grow, we need to deepen our partnerships and bring in new ones around the world.

Q7:

KAVA functions as a reserve currency in situations where the system is undercollateralized. In such cases new KAVA is minted and used to buy USDX off the market until USDX becomes safely overcollateralized.

Meaning, there will be no max supply of KAVA?

  • Answer: Yes, there is no max supply of Kava.

Q8:

Why Kava?

  • Answer: ...because people are long BTC and the best way to go long BTC without giving up custody is Kava's platform. Because it is MakerDao for bitcoin. Bitcoin has a 10x market cap of ETH and Maker is 10x the size of Kava. I think we're pretty undervalued right now.

Q9:

How do you plan to make liquidity in Kava?

  • Answer: Working with Binance for the IEO and as the first exchange for KAVA to trade on will be a huge boost in increasing the liquidity of trading KAVA.

Q10:

Most crypto investors or crypto users prefer easy transaction and low fees, what can we expect from KAVA about this?

  • Answer: Transaction fees are very low and confirm if seconds. The user experience is quite good on Tendermint-based blockchains.

Q11:

How do I become a note validator on KavA?

Q12:

It is great to know that KAVA is the first DEFI-supported project sponsored by Binance Launchpad, do you think this is the meaning that CZ brings: Opening the DEFI era, as a leader, you feel like how ?

  • Answer: We are the first DeFi platform that Launchpad has supported. We are a very strategic blockchain for major crypto like BNB. Kava's platform will bring more utility to the users of BNB and the Binance DEX. It feels good of course to have validation from the biggest players in the space like Cosmos, Ripple, CZ/Binance, etc.

Q13:

Since decentralized finance applications is already dominating, how do you intend to surpass those leading in the market?

  • Answer: The leaders are only addressing ethereum. BTC, XRP, BNB, ATOM is a much larger set to go after that current players cannot.

Q14:

What does Ripple play in the Kava's ecosystem, since Ripple is like a top tier company and it’s impressive that you are partnered with them?

  • Answer: Ripple is an equity investor in Kava and a big supporter of our work in cross-chain settlement research and implementations. Ripple's XRP is a great asset in terms of users and liquidity that the Kava platform can use. In addition, Ripple's money service business customers are asking for a stable coin for remittances to avoid the currency heading risk that XRP presents. Ripple will not use USDC or other stable coins, but they are open to using USDX as it can be XRP-backed.

Q15:

Considering the connectivity, Libra could be the biggest competitor if KAVA leverages interchain for efficiency.

  • Answer: With regard to USDX, it is important to understand the users interacting with the Kava blockchain have no counterparty that people could go after for legal actions. A user getting a USDX loan has no counterparty. The software holds the collateral and creates the loan. The only laws that would apply are to the very users that are using the system.

Q16:

Wonder how KAVA will compete with the tech giants

  • Answer: Libra is running into extreme issues with the US Senate and regulators. Even the G7-G20 groups are worried. Its important to understand that Libra is effectively a permissioned system. Only big companies that law makers can go after are able to run nodes. In Kava, nodes can be run by anyway and our nodes are based all over the world. It's incredibly hard for a law maker to take down Kava because they would need to find and legally enforce hundreds of business in different jurisdictions to comply. We have an advantage in this way over the larger projects like Libra or Clayton.

Q17:

In long-term, what's the strategy that KAVA has for covering the traditional finance users as well? Especially regarding the "stability"

  • Answer: Technical risk is unavoidable for DeFi. Only time will tell if a system is trustworthy and its never 100% that it will not fail or be hacked. This is true with banks and other financial systems as well. I think for DeFi, the technical risk needs to be priced in to the expected returns to compensate the market. DeFi does have a better user experience - requiring no credit score, identity, or KYC over centralized solutions.
  • With our multi-collateral CDP system, even with it overcollateralized, people can get up to 3x leverage on assets. Take 100 USD in BTC, get a USDX loan for 66 USDX, then buy $66 BTC and do another loan - you can do this with a program to get 3x leverage with the same risk profile. This is enough for most people.
  • However, it will be possible once we have Kava's CDP platform to extend it into products that offer undercollateralized financial products. For example, if USER 1 + USER 2 use payment channels to lock up their USDX, they can use Kava's price feeds to place bets between each other using their locked assets. They can bet that for every $1 BTC/USD moves, the other party owes 3x. In this way we can even do 100x leverage or 1000x leverage and create very fun products for people to trade with. Importantly, even in places where margin trading is regulated and forbidden, Kava's platform will remain open access and available.

Q18:

In long-term, what's the strategy that KAVA has for covering the traditional finance users as well? Especially regarding the "stability"

  • Answer: Kava believes that stable coins should be backed not just by crypto or fiat, but any widely used, highly liquid asset. We think in the future the best stablecoin would be backed by a basket of very stable currencies that include crypto and fiat or whatever the market demands.

Q19:

Compound, maker they're trying to increase their size via the competitive interests rates. THough it shows good return in terms of growth rate, still it's for short-term. Wonder other than financial advantage, KAVA has more for the users' needs?

  • Answer: Robert, the CEO of Compound is an investor and advisor to Kava. We think what Compound does with money markets is amazing and hope to integrate when they support more than just Ethereum assets. Kava's advantage vs others is to provide basic DeFi services like returns on crypto and stable coins today when no other platform offers that. Many platforms support ETH, but no platform can support BTC, XRP, BNB, and ATOM in a decentralized way without requiring centralized custody of these assets.

Q20:

The vast majority of the cryptocurrency community's priorities is symbolic pricing. When prices rise, the community rejoices and grows. When they fall, many people begin to cast in a negative way. How will KAVA solve the negative problem when the price goes down? What is your plan to strengthen and develop the community to persuade more people to look at the product than the price?

  • Answer: We believe price is an important factor for faith in the market. One of Kava's key initiatives was selecting only long-term partners that are willing to work with kava for 2 years. That is why even after 6 months, 0 private investor or kava team tokens will be liquid on the market.
  • We believe not in fast pumps and then dumps that destroy faith, but rather we try and operate the best we can for long-term sustainable growth over time. It's always hard to control factors in the market, and some factors are out of our control such as BTC price correlations, etc - however, we treat this like a public company stock - we want long-term growth of Kava and try to make sure our whole community of Kava holders is aligned with that the best we can.

Q21:

Do you have any plans to attract non-crypto investors to Kava and how? What are the measures to increase awareness of kava in non-crypto space?

  • Answer: We are 100% focused on crypto, not the general market. We solve the problems of crypto traders and investors - not the average grandma who needs a payment solution. Kava is geared for decentralized leverage and hedging.

Q22:

Adoption is crucial for all projects and crypto companies, what strategy are you gonna use/follow or u are now following to get Kava adopted and used by many people all over the world?

Revenue is an important aspect for all projects in order to survive and keep the project/company up and running for long term, what are the ways that Kava generates profits/revenue and what is its revenue model?

  • Answer: We have already partnered with several large exchanges, long-term VCs, and large projects like Ripple and Cosmos. These are key ways for us to grow our community. As we build support for more assets, we plan to promote Kava's services to those new communities of traders.
  • Kava generates revenue as more people use the platform. As the platform is used, KAVA tokens are burned when users pay stability fees. This deflates the total supply of Kava and should in most cases give rise to the value of KAVA like a stock-buyback in the public markets.

Q23:

In order to be success in Loan project of Cryptocurrency, I think marketing is very important to make people using this service without any registration. What is main strategy for marketing?

  • Answer: Our main strategy is to build a great experience and offer products that are not available to communities with demand. Currently no DeFi products can serve BTC users for example. Centralized exchanges can, but nothing truly trustless. Kava's platform can finally give the vast audiences of BTC, BNB, and ATOM holders access to core DeFi services they cannot get on their own due to the smart contract limitations of those platforms.

Q24:

Currently, some project have policies for their ambassadors to create a contribution and attract recognition for the project! So the KAVA team plans to implement policies and incentives for KAVA ambassadors?

  • Answer: Yes, we will be creating a KAVA ambassador program and releasing that soon. Please follow our social media channels to learn about it in the coming weeks.

Q25:

Currently there are so many KAVA tokens sold on exchanges, why is this happening while KAVA is going to IEO on Binance? Are those KAVA codes fake or not?

  • Answer: For everyone's safety, please understand Kava tokens do not exist yet and they will only exist starting with the Binance IEO. Any other token listings or offerings of Kava are not supported by Kava Labs and I highly discourage you all from trying to get them there. It is most likely a big scam. Please only trust Binance for this.

Q26:

KAVA have two tokens, the first is called Kava - a governance and staking token; the second is called USDX - an algorithmically managed crypto-backed stable coin. What are the advantages of USDX compared to other stablecoins such as: USDT, USDC, TUSD, GUSD, ...?

  • Answer: USDX is one of the few stablecoins to be fully backed by crypto-assets. This means that we do not deal with fiat to back the value, and thus we don't have some of the issues when it comes to storing fiat funds with banks and custodians. This also makes our product fully digital and built for the future of crypto growth.

Q27:

As a CEO, does your background in Esports and Gaming industry help anything to your management and development of KAVA Labs?

  • Answer: Esports no. But having been a multi-time venture-backed foundeCEO and have gone through the start-up phase before has made creating and running a 2nd company easier. Right now Kava is still small, Fnatic had over 80 employees. It was at a larger scale. I would say developing software is much more than doing the hardware at fnaticgear.com

Q28:

Why did Kava choose to launch IEO on Binance and not other exchanges like: Kucoin, Houbi, Gate, ....?

  • Answer: Kava had a lot of interest from exchanges to partner with for IEO. We decided based on a lot of factors such as userbase, diverse exposure across multiple regions and countries, and an amazing team that provides so much insight into so many communities such as this one. Binance has been a tremendous partner and we also look forward to continuing our partnership far into the future.

Q29:

Currently if Search on coinmarketcap has 3 types of stablecoins bearing the USDX symbol (but these 3 stablecoins are no information). So, what will KAVA do to let users know that Kava's USDX is another stablecoin?

  • Answer: All these USDX have no volume or listings. We will be on Binance. I am not worried.

Q30:

In addition to the Token Allocation for Binance Launchpad, what is the Token Treasury in the Initial Circulating Supply?

  • Answer: This is controlled by Kava Labs, but with the big cash we have saved from fundraising, we see no reason why these tokens would be sold on the market. The treasury tokens are for use in grants, ecosystem growth initiatives, development, and other incentive programs to drive adoption of the platform.

Q31:

How you will compete with your competitors? Currently i don't see much but for future how you will maintain this consistency ? No doubt it is Great and Unique project, what is the main problem that #KAVA is currently facing?

  • Answer: Because our industry is just starting out, I don't like to think of them as our direct competitors. We are all working to grow the size of the pie rather than get a larger slice from a small pie. The one thing that we believe will allow us to stand apart is the community we are building. Being able to utilize our own community along with Cosmos and our other partners like Binance for the IEO, we have a strong footing to get a lot of early users onto our platform. Also, we are also focusing on growing Kava internationally particularly Asia. We hope to build our platform for an even larger userbase than just the west.

Q32:

How do you explain your project to a random person who has never heard of your project?

  • Answer: non-crypto = Kava is a lending platform for users of cryptocurrencies.
  • crypto = Kava is a cross-chain DeFi platform for loans and stablecoins backed by BTC, BNB, XRP, ATOM and other major cryptocurrencies.

Q33:

Will KAVA team have a plan on implementing DAO module on your platform since its efficiency on autonomy, decentralization and transparency?

  • Answer: All voting is already transparent on the Kava blockchain. We approved a number of proposals on our test net.

Q34:

how to use usdx token :only for your platform or you have plan to use usdx for payment ?

  • Answer: Payments is a nice use case, but demand for crypto payments is still small. We may choose to focus here later if demand for crypto payments increases. Currently it is quite small with the bulk of use remaining in trading and speculative use cases.

Q35:

Do you have plans to spread KAVA ecosystem across other continents. if yes, what are the strategies and how can I as a community member contribute to making it possible?

  • Answer: We are already across many continents - I don't think we are in antarctica yet. Africa might be light on nodes as well. I think as we grow on major exchanges like Binance, new node operators will get interested and help decentralize Kava further.

Q36:

Maker's CDP lending system is on top in this market and its Dominance is currently sitting on 64.90 % , how kava will compete will maker and compound?

  • Answer: adding assets like bitcoin which have more value and more users than ETH. It's a bigger market that Maker cannot compete with Kava in.

Q37:

Currently, the community is too concerned about the price. As prices rise, the community rejoice and grow, when falling, many people start throwing negatively. So what is KAVA's solution to getting people to focus on the project rather than the price of the token?

What is your plan to strengthen and grow the community to persuade more individuals to look at the product than the price?

  • Answer: We also share similar concerns as price and price direction is always a huge factor in the crypto industry. A lot of people of course are very short-term focused on flipping for bigger profits. One of the solutions, and what Kava has done, is to make sure that everything structured is for the long-term. So that makes sure that our investors and employees are all focused on long-term gains and growth. Locking vesting periods are part of that alignment. Another thing is that we at Kava are very transparent in our progress and development. We will be regularly posting updates within our own communities to allow our users and followers to keep up with everything we're up to. Please follow us or look at our github if you're interested!

Q38:

How did Kava get on Piexgo?

  • Answer: We did not work with Piexgo. We have not distributed tokens to any exchange other than Binance. I cannot speak to what is going on there, but I would be very wary of what is happening there.

Q39:

Why was the 1st round price so much lower than the current price

  • Answer: It is natural to worry that early investors got better pricing and could dump on the market. I can assure you that our investors are in this for the long-term. All private sale rounds signed 2 year contracts to run validators - and if they don't they forfeit their tokens. You can compare our release schedule to any other project. We have one of the most restricted circulating supply schedules of any project EVER and its because all our investors are commiting to the long-term success of the project and believe in Kava.
  • About the pricing itself - it is always a function of traction like for any start-up. When we made our public announcement about the project in June, we were only a 4 man team with just some github code. We could basically run a network with a single node, our own. Which is relatively worthless. I think our pricing of Kava at this time was justified. We were effectively a seed-stage company without a product or working network.
  • By July we made severe progress on the development side and the business side. We successful launched our first test net with the help of over 70 validator business partners around the world. We had a world-wide network of hundreds of people supporting us with people and resources at this point and the risk we would fail in launching a working product was much lower. At this point, the Kava project was valued at $25M. At this point, we had many VCs and investors asking for Kava tokens that we turned away. We only accepted validators that would help us launch the network. It was our one and only goal.
  • Fast forward to today, the IEO price simply reflects the traction and market demand for Kava. Our ecosystem is much larger than it was even a month ago. We have support from Ripple, Cosmos, and Binance amongst other large crypto projects. We have 100+ validators securing our network with very sophisticated high-availability set-ups. In addition, our ecosystem partners have built products for Kava - such as block explorers and others are working on native integrations to wallets and exchanges. Launchpad will be very big for us. Kava is a system designed to cater to crypto traders and investors and in a matter of days we distributed via Binance Launchpad and put in the hands of 130+ countries and tens of thousands of users overnight. It doesn't get more DeFi than that.

Q40:

What is the treasury used for?

  • Answer: Kava's treasury is for ecosystem growth activities.
  • Investors in financing rounds prior to the IEO have entered into long-term lock-up agreements in-line with their belief in Kava’s exciting long-term growth potential and to allow the projects token price to find stability. Following the IEO, the only tokens in circulation will be those sold through the IEO on Binance and the initial Treasury tokens released. No private sale investor tokens are in circulation until the initial release at the end of Q1 2020 and then gradually over the [36] months The initial Treasury tokens in circulation will be used for a mixture of ecosystem grants, the expenses associated with the IEO as well as initial market making requirements as is typical with a listing of this size. Kava remains well financed to execute our roadmap following the IEO and do not envisage any need for any material financings or token sales for the foreseeable future.

Q41:

Everyone have heard about the KAVA token, and read about it. But it would be great to hear your explanation about it. What is the Kava token, what is it's utility? :)

  • Answer: The Kava token plays many roles. KAVA is the native staking token of the Kava blockchain and is used for securing the network. KAVA is delegated to validators, basically professional node operators that run highly-available servers to secure the Kava blockchain. The top 100 validators by weight of staked KAVA earn block rewards that range from 3-20% APR based on the total amount staked in the network. These rewards are split between the validators and the KAVA holders.
  • When users of the platform repay their loans, they must a stability fee (a percentage of the loan) in KAVA tokens. These tokens are burned by the system, effectively deflating the total supply overtime as more users use the CDP system.
  • KAVA is also the primary token used in governance of the platform. KAVA token holders can vote on key system parameter changes and upgrades such as what assets to support, how much USDX in total can be loaned by the system, what the debt-to-collateral ratio needs to be, the stability fees, etc. KAVA holders have a very important responsibility to govern the system well.
  • Lastly, Kava functions as a "Lender of Last Resort" meaning if USDX ever gets undercollateralized because the underlying asset prices drop suddenly and the system manages it poorly, KAVA is inflated in these emergency situations and used to purchase USDX off the market until USDX reaches a state of being over collateralized again. KAVA holders have incentive to only support the good high quality assets so risk of the system is managed responsibly.

Q42:

No matter how perfect and technically thought-out a DeFi protocol is, it cannot be completely protected from any unplanned situations (such as extreme market fluctuations, some legal issues, etc.)

Ecosystem members, in particular the validators on whom KAVA relies on fundamental decision-making rights, should be prepared in advance for any "critical" scenario. Considering that, unlike the same single-collateral MakerDAO, KAVA will be a multi-collateral CDP system, this point is probably even more relevant here.

In this regard, please answer the following question: Does KAVA have a clear risk management model or strategy and how decentralized is / will it be?

  • Answer: Simialar to other CDP systems and MakerDAO we do have a system freeze function where in cases of extreme issues, we can stop the auction mechanisms and return all collateral.

Q43:

Did you know that "Kava" is translated into Ukrainian like "Coffee"? I personally do love drinking coffee. I plunge into the fantasy world. Why did you name your project "Kava" What is the story behind it? What idea / fantasy did your project originate from, which inspired you to create it?

  • Answer: Kava is coffee to you.
  • Kava is Hippopotamus to Japanese.
  • Cava is a region in Spain
  • Kava is also a root that is used in tea which makes your mouth numb.
  • Kava is also crow in Hindi.
  • Kava last but not least is a DeFi platform launching on Binance :)
  • We liked the sound of Kava it was as simple as that. It doesn't have much meaning in the USA where I am from. But it's short sweet and when we were just starting, Kava.io was available for a reasonable price

Q44:

What incentives does a lender get if a person chooses to pay with KAVA? Is there a discount on interest rates on the loan amount if you pay with KAVA? Do I have to pass the KYC procedure to apply for a small loan?

  • Answer: There is no KYC for Kava. Its an open blockchain software platform where anyone with a computer can connect to it and use it.

Q45:

Let's say, I decided to bond my cryptocurrency and got USDX stable coins. For now, it`s an unknown stable coin (let's be honest). Do you plan to add USDX to other famous exchanges? Also, you have spoken about the USDX staking and that the percentage would be higher than for other stable coins. Please be so kind to tell us what is the average annual interest rate and what are the conditions of staking?

  • Answer: Yes we have several large exchanges willing to support USDX from the start. Binance/Binance-DEX is one you should all know ;)
  • The average annual rates for USDX will depend on market conditions. The rate is actually provided by the CDP fees users pay. The system reallocates a portion of those fees to USDX users. In times when USDX use needs to grow, the rates will be higher to incentivize use. When demand is strong, we can reduce the rates.

Q46:

Why should i use and choose Kava's loan if i can use the similar margin trade on Binance?

  • Answer: If margin is available to you and you trust the exchange then you should do whatever is cheaper. For a US citizen and others, margin is often not available and if it is, only for a few asset types as collateral. Kava aims to address this and offer this to everyone.

Q47:

The IEO price is $ 0.46 while the price of the first private sale is $ 0.075. Don't you think that such price gap can negatively affect the liquidity of the token and take away the desire to buy a token on the exchange?

  • Answer: It is natural to worry that early investors got better pricing and could dump on the market. I can assure you that our investors are in this for the long-term. All private sale rounds signed 2 year contracts to run validators - and if they don't they forfeit their tokens. You can compare our release schedule to any other project. We have one of the most restricted circulating supply schedules of any project EVER and its because all our investors are commiting to the long-term success of the project and believe in Kava.
  • About the pricing itself - it is always a function of traction like for any start-up.

At this point, the Kava project was valued at $25M. At this point, we had many VCs and investors asking for Kava tokens that we turned away. We only accepted validators that would help us launch the network. It was our one and only goal.
  • Fast forward to today, the IEO price simply reflects the traction and market demand for Kava. Our ecosystem is much larger than it was even a month ago. We have support from Ripple, Cosmos, and Binance amongst other large crypto projects. We have 100+ validators securing our network with very sophisticated high-availability set-ups. In addition, our ecosystem partners have built products for Kava - such as block explorers and others are working on native integrations to wallets and exchanges. Launchpad will be very big for us. Kava is a system designed to cater to crypto traders and investors and in a matter of days we distributed via Binance Launchpad and put in the hands of 130+ countries and tens of thousands of users overnight. It doesn't get more DeFi than that.
  • TLDR - I think KAVA is undervalued and the liquid supply of tokens is primarily from the IEO so its a safer bet than other IEOs. If the price drops, it will be from the overall market conditions or fellow IEO users not due private sale investors or team sell-offs.

Q48:

Can you introduce some information abouts KAVA Deflationary Fee Structure? With the burning mechanism, does it mean KAVA will never reach its max supply?

  • Answer: When loans are repaid, users pay a fee in Kava. This is burned. However, Kava does not have a max supply. It has a starting supply of 100M. It inflates for block rewards 3-20% APR AND it inflates when the system is at risk of under collateralization. At this time, more Kava is minted and used to purchase USDX off the market until it reaches full collateralization again.
  • TLDR: If things go well, and governance is good, Kava deflates and hopefully appreciates in value. If things go wrong, Kava holders get inflated.

Q49:

In your opinion what are advantage of decentralized finance over centralized?

  • Answer: One of the main advantages is not needing to pay the costs of regulation and compliance. Open financial software that is usable by anyone removes middle men fees and reduces the barrier for new entrants to enter and make new products. Also DeFI has an edge in terms of onboarding - to get a bank account or an exchange account you need to do lots of KYC and give private info. That takes time and is troublesome. With DeFi you just load up your funds and transact. Very fast user flows.

Q50:

Plan, KAVA how to raise capital? Kava is being supported by more than 100 business entities around the world, including major cryptocurrency investment funds like Ripple and Cosmos, so what did kava do to convince investors to join the project?

  • Answer: We have been doing crypto research and development for years. Ripple and Cosmos were partners before we even started this blockchain with Kava Labs. When we announced Kava the DeFi platform they knew us already to do good work and they liked the idea so they support us.

Which are your Top 5 favourite coins out of the Top 100? An analysis.

I am putting together my investment portfolio for 2018 and made a complete summary of the current Top 100. Interestingly, I noticed that all coins can be categorized into 12 markets. Which markets do you think will play the biggest role in the coming year?
Here is a complete overview of all coins in an excel sheet including name, market, TPS, risk profile, time since launch (negative numbers mean that they are launching that many months in the future) and market cap. You can also sort by all of these fields of course. Coins written in bold are the strongest contenders within their market either due to having the best technology or having a small market cap and still excellent technology and potential. https://docs.google.com/spreadsheets/d/1s8PHcNvvjuy848q18py_CGcu8elRGQAUIf86EYh4QZo/edit#gid=0
The 12 markets are
  1. Currency 13 coins
  2. Platform 25 coins
  3. Ecosystem 9 coins
  4. Privacy 10 coins
  5. Currency Exchange Tool 8 coins
  6. Gaming & Gambling 5 coins
  7. Misc 15 coins
  8. Social Network 4 coins
  9. Fee Token 3 coins
  10. Decentralized Data Storage 4 coins
  11. Cloud Computing 3 coins
  12. Stable Coin 2 coins
Before we look at the individual markets, we need to take a look of the overall market and its biggest issue scalability first:
Cryptocurrencies aim to be a decentralized currency that can be used worldwide. Its goal is to replace dollar, Euro, Yen, all FIAT currencies worldwide. The coin that will achieve that will be worth several trillion dollars.
Bitcoin can only process 7 transactions per second (TPS). In order to replace all FIAT, it would need to perform at at least VISA levels, which usually processes around 3,000 TPS, up to 25,000 TPS during peak times and a maximum of 64,000 TPS. That means that this cryptocurrency would need to be able to perform at least several thousand TPS. However, a ground breaking technology should not look at current technology to set a goal for its use, i.e. estimating the number of emails sent in 1990 based on the number of faxes sent wasn’t a good estimate.
For that reason, 10,000 TPS is the absolute baseline for a cryptocurrency that wants to replace FIAT. This brings me to IOTA, which wants to connect all 80 billion IoT devices that are expected to exist by 2025, which constantly communicate with each other, creating 80 billion or more transactions per second. This is the benchmark that cryptocurrencies should be aiming for. Currently, 8 billion devices are connected to the Internet.
With its Lightning network recently launched, Bitcoin is realistically looking at 50,000 possible soon. Other notable cryptocurrencies besides IOTA and Bitcoin are Nano with 7,000 TPS already tested, Dash with several billion TPS possible with Masternodes, Neo, LISK and RHOC with 100,000 TPS by 2020, Ripple with 50,000 TPS, Ethereum with 10,000 with Sharding.
However, it needs to be said that scalability usually goes at the cost of decentralization and security. So, it needs to be seen, which of these technologies can prove itself resilient and performant.
Without further ado, here are the coins of the first market

Market 1 - Currency:

  1. Bitcoin: 1st generation blockchain with currently bad scalability currently, though the implementation of the Lightning Network looks promising and could alleviate most scalability concerns, scalability and high energy use.
  2. Ripple: Centralized currency that might become very successful due to tight involvement with banks and cross-border payments for financial institutions; banks and companies like Western Union and Moneygram (who they are currently working with) as customers customers. However, it seems they are aiming for more decentralization now.https://ripple.com/dev-blog/decentralization-strategy-update/. Has high TPS due to Proof of Correctness algorithm.
  3. Bitcoin Cash: Bitcoin fork with the difference of having an 8 times bigger block size, making it 8 times more scalable than Bitcoin currently. Further block size increases are planned. Only significant difference is bigger block size while big blocks lead to further problems that don't seem to do well beyond a few thousand TPS. Opponents to a block size argue that increasing the block size limit is unimaginative, offers only temporary relief, and damages decentralization by increasing costs of participation. In order to preserve decentralization, system requirements to participate should be kept low. To understand this, consider an extreme example: very big blocks (1GB+) would require data center level resources to validate the blockchain. This would preclude all but the wealthiest individuals from participating.Community seems more open than Bitcoin's though.
  4. Litecoin : Little brother of Bitcoin. Bitcoin fork with different mining algorithm but not much else.Copies everything that Bitcoin does pretty much. Lack of real innovation.
  5. Dash: Dash (Digital Cash) is a fork of Bitcoin and focuses on user ease. It has very fast transactions within seconds, low fees and uses Proof of Service from Masternodes for consensus. They are currently building a system called Evolution which will allow users to send money using usernames and merchants will find it easy to integrate Dash using the API. You could say Dash is trying to be a PayPal of cryptocurrencies. Currently, cryptocurrencies must choose between decentralization, speed, scalability and can pick only 2. With Masternodes, Dash picked speed and scalability at some cost of decentralization, since with Masternodes the voting power is shifted towards Masternodes, which are run by Dash users who own the most Dash.
  6. IOTA: 3rd generation blockchain called Tangle, which has a high scalability, no fees and instant transactions. IOTA aims to be the connective layer between all 80 billion IOT devices that are expected to be connected to the Internet in 2025, possibly creating 80 billion transactions per second or 800 billion TPS, who knows. However, it needs to be seen if the Tangle can keep up with this scalability and iron out its security issues that have not yet been completely resolved.
  7. Nano: 3rd generation blockchain called Block Lattice with high scalability, no fees and instant transactions. Unlike IOTA, Nano only wants to be a payment processor and nothing else, for now at least. With Nano, every user has their own blockchain and has to perform a small amount of computing for each transaction, which makes Nano perform at 300 TPS with no problems and 7,000 TPS have also been tested successfully. Very promising 3rd gen technology and strong focus on only being the fastest currency without trying to be everything.
  8. Decred: As mining operations have grown, Bitcoin’s decision-making process has become more centralized, with the largest mining companies holding large amounts of power over the Bitcoin improvement process. Decred focuses heavily on decentralization with their PoW Pos hybrid governance system to become what Bitcoin was set out to be. They will soon implement the Lightning Network to scale up. While there do not seem to be more differences to Bitcoin besides the novel hybrid consensus algorithm, which Ethereum, Aeternity and Bitcoin Atom are also implementing, the welcoming and positive Decred community and professoinal team add another level of potential to the coin.
  9. Aeternity: We’ve seen recently, that it’s difficult to scale the execution of smart contracts on the blockchain. Crypto Kitties is a great example. Something as simple as creating and trading unique assets on Ethereum bogged the network down when transaction volume soared. Ethereum and Zilliqa address this problem with Sharding. Aeternity focuses on increasing the scalability of smart contracts and dapps by moving smart contracts off-chain. Instead of running on the blockchain, smart contracts on Aeternity run in private state channels between the parties involved in the contracts. State channels are lines of communication between parties in a smart contract. They don’t touch the blockchain unless they need to for adjudication or transfer of value. Because they’re off-chain, state channel contracts can operate much more efficiently. They don’t need to pay the network for every time they compute and can also operate with greater privacy. An important aspect of smart contract and dapp development is access to outside data sources. This could mean checking the weather in London, score of a football game, or price of gold. Oracles provide access to data hosted outside the blockchain. In many blockchain projects, oracles represent a security risk and potential point of failure, since they tend to be singular, centralized data streams. Aeternity proposes decentralizing oracles with their oracle machine. Doing so would make outside data immutable and unchangeable once it reaches Aeternity’s blockchain. Of course, the data source could still be hacked, so Aeternity implements a prediction market where users can bet on the accuracy and honesty of incoming data from various oracles.It also uses prediction markets for various voting and verification purposes within the platform. Aeternity’s network runs on on a hybrid of proof of work and proof of stake. Founded by a long-time crypto-enthusiast and early colleague of Vitalik Buterin, Yanislav Malahov. Promising concept though not product yet
  10. Bitcoin Atom: Atomic Swaps and hybrid consenus. This looks like the only Bitcoin clone that actually is looking to innovate next to Bitcoin Cash.
  11. Dogecoin: Litecoin fork, fantastic community, though lagging behind a bit in technology.
  12. Bitcoin Gold: A bit better security than bitcoin through ASIC resistant algorithm, but that's it. Not that interesting.
  13. Digibyte: Digibyte's PoS blockchain is spread over a 100,000+ servers, phones, computers, and nodes across the globe, aiming for the ultimate level of decentralization. DigiByte rebalances the load between the five mining algorithms by adjusting the difficulty of each so one algorithm doesn’t become dominant. The algorithm's asymmetric difficulty has gained notoriety and been deployed in many other blockchains.DigiByte’s adoption over the past four years has been slow. It’s still a relatively obscure currency compared its competitors. The DigiByte website offers a lot of great marketing copy and buzzwords. However, there’s not much technical information about what they have planned for the future. You could say Digibyte is like Bitcoin, but with shorter blocktimes and a multi-algorithm. However, that's not really a difference big enough to truly set themselves apart from Bitcoin, since these technologies could be implemented by any blockchain without much difficulty. Their decentralization is probably their strongest asset, however, this also change quickly if the currency takes off and big miners decide to go into Digibyte.
  14. Bitcoin Diamond Asic resistant Bitcoin and Copycat

Market 2 - Platform

Most of the cryptos here have smart contracts and allow dapps (Decentralized apps) to be build on their platform and to use their token as an exchange of value between dapp services.
  1. Ethereum: 2nd generation blockchain that allows the use of smart contracts. Bad scalability currently, though this concern could be alleviated by the soon to be implemented Lightning Network aka Plasma and its Sharding concept.
  2. EOS: Promising technology that wants to be able do everything, from smart contracts like Ethereum, scalability similar to Nano with 1000 tx/second + near instant transactions and zero fees, to also wanting to be a platform for dapps. However, EOS doesn't have a product yet and everything is just promises still. Highly overvalued right now. However, there are lots of red flags, have dumped $500 million Ether over the last 2 months and possibly bought back EOS to increase the size of their ICO, which has been going on for over a year and has raised several billion dollars. All in all, their market cap is way too high for that and not even having a product.
  3. Cardano: Similar to Ethereum/EOS, however, only promises made with no delivery yet, highly overrated right now. Interesting concept though. Market cap way too high for not even having a product. Somewhat promising technology.
  4. VeChain: Singapore-based project that’s building a business enterprise platform and inventory tracking system. Examples are verifying genuine luxury goods and food supply chains. Has one of the strongest communities in the crypto world. Most hyped token of all, with merit though.
  5. Neo: Neo is a platform, similar to Eth, but more extensive, allowing dapps and smart contracts, but with a different smart contract gas system, consensus mechanism (PoS vs. dBfT), governance model, fixed vs unfixed supply, expensive contracts vs nearly free contracts, different ideologies for real world adoption. There are currently only 9 nodes, each of which are being run by a company/entity hand selected by the NEO council (most of which are located in china) and are under contract. This means that although the locations of the nodes may differ, ultimately the neo council can bring them down due to their legal contracts. In fact this has been done in the past when the neo council was moving 50 million neo that had been locked up. Also dbft (or neo's implmentation of it) has failed underload causing network outages during major icos. The first step in decentralization is that the NEO Counsel will select trusted nodes (Universities, business partners, etc.) and slowly become less centralized that way. The final step in decentralization will be allowing NEO holders to vote for new nodes, similar to a DPoS system (ARK/EOS/LISK). NEO has a regulation/government friendly ideology. Finally they are trying to work undewith the Chinese government in regards to regulations. If for some reason they wanted it shut down, they could just shut it down.
  6. Stellar: PoS system, similar goals as Ripple, but more of a platform than only a currency. 80% of Stellar are owned by Stellar.org still, making the currency centralized.
  7. Ethereum classic: Original Ethereum that decided not to fork after a hack. The Ethereum that we know is its fork. Uninteresing, because it has a lot of less resources than Ethereum now and a lot less community support.
  8. Ziliqa: Zilliqa is building a new way of sharding. 2400 tpx already tested, 10,000 tps soon possible by being linearly scalable with the number of nodes. That means, the more nodes, the faster the network gets. They are looking at implementing privacy as well.
  9. QTUM: Enables Smart contracts on the Bitcoin blockchain. Useful.
  10. Icon: Korean ethereum. Decentralized application platform that's building communities in partnership with banks, insurance providers, hospitals, and universities. Focused on ID verification and payments. No big differentiators to the other 20 Ethereums, except that is has a product. That is a plus. Maybe cheap alternative to Ethereum.
  11. LISK: Lisk's difference to other BaaS is that side chains are independent to the main chain and have to have their own nodes. Similar to neo whole allows dapps to deploy their blockchain to. However, Lisk is currently somewhat centralized with a small group of members owning more than 50% of the delegated positions. Lisk plans to change the consensus algorithm for that reason in the near future.
  12. Rchain: Similar to Ethereum with smart contract, though much more scalable at an expected 40,000 TPS and possible 100,000 TPS. Not launched yet. No product launched yet, though promising technology. Not overvalued, probably at the right price right now.
  13. ARDR: Similar to Lisk. Ardor is a public blockchain platform that will allow people to utilize the blockchain technology of Nxt through the use of child chains. A child chain, which is a ‘light’ blockchain that can be customized to a certain extent, is designed to allow easy self-deploy for your own blockchain. Nxt claims that users will "not need to worry" about security, as that part is now handled by the main chain (Ardor). This is the chief innovation of Ardor. Ardor was evolved from NXT by the same company. NEM started as a NXT clone.
  14. Ontology: Similar to Neo. Interesting coin
  15. Bytom: Bytom is an interactive protocol of multiple byte assets. Heterogeneous byte-assets (indigenous digital currency, digital assets) that operate in different forms on the Bytom Blockchain and atomic assets (warrants, securities, dividends, bonds, intelligence information, forecasting information and other information that exist in the physical world) can be registered, exchanged, gambled and engaged in other more complicated and contract-based interoperations via Bytom.
  16. Nxt: Similar to Lisk
  17. Stratis: Different to LISK, Stratis will allow businesses and organizations to create their own blockchain according to their own needs, but secured on the parent Stratis chain. Stratis’s simple interface will allow organizations to quickly and easily deploy and/or test blockchain functionality of the Ethereum, BitShares, BitCoin, Lisk and Stratis environements.
  18. Status: Status provides access to all of Ethereum’s decentralized applications (dapps) through an app on your smartphone. It opens the door to mass adoption of Ethereum dapps by targeting the fastest growing computer segment in the world – smartphone users.16. Ark: Fork of Lisk that focuses on a smaller feature set. Ark wallets can only vote for one delegate at a time which forces delegates to compete against each other and makes cartel formations incredibly hard, if not impossible.
  19. Neblio: Similar to Neo, but 30x smaller market cap.
  20. NEM: Is similar to Neo No marketing team, very high market cap for little clarilty what they do.
  21. Bancor: Bancor is a Decentralized Liquidity Network that allows you to hold any Ethereum token and convert it to any other token in the network, with no counter party, at an automatically calculated price, using a simple web wallet.
  22. Dragonchain: The Purpose of DragonChain is to help companies quickly and easily incorporate blockchain into their business applications. Many companies might be interested in making this transition because of the benefits associated with serving clients over a blockchain – increased efficiency and security for transactions, a reduction of costs from eliminating potential fraud and scams, etc.
  23. Skycoin: Transactions with zero fees that take apparently two seconds, unlimited transaction rate, no need for miners and block rewards, low power usage, all of the usual cryptocurrency technical vulnerabilities fixed, a consensus mechanism superior to anything that exists, resistant to all conceivable threats (government censorship, community infighting, cybenucleaconventional warfare, etc). Skycoin has their own consensus algorithm known as Obelisk written and published academically by an early developer of Ethereum. Obelisk is a non-energy intensive consensus algorithm based on a concept called ‘web of trust dynamics’ which is completely different to PoW, PoS, and their derivatives. Skywire, the flagship application of Skycoin, has the ambitious goal of decentralizing the internet at the hardware level and is about to begin the testnet in April. However, this is just one of the many facets of the Skycoin ecosystem. Skywire will not only provide decentralized bandwidth but also storage and computation, completing the holy trinity of commodities essential for the new internet. Skycion a smear campaign launched against it, though they seem legit and reliable. Thus, they are probably undervalued.

Market 3 - Ecosystem

The 3rd market with 11 coins is comprised of ecosystem coins, which aim to strengthen the ease of use within the crypto space through decentralized exchanges, open standards for apps and more
  1. Nebulas: Similar to how Google indexes webpages Nebulas will index blockchain projects, smart contracts & data using the Nebulas rank algorithm that sifts & sorts the data. Developers rewarded NAS to develop & deploy on NAS chain. Nebulas calls this developer incentive protocol – basically rewards are issued based on how often dapp/contract etc. is used, the more the better the rewards and Proof of devotion. Works like DPoS except the best, most economically incentivised developers (Bookkeeppers) get the forging spots. Ensuring brains stay with the project (Cross between PoI & PoS). 2,400 TPS+, DAG used to solve the inter-transaction dependencies in the PEE (Parallel Execution Environment) feature, first crypto Wallet that supports the Lightening Network.
  2. Waves: Decentralized exchange and crowdfunding platform. Let’s companies and projects to issue and manage their own digital coin tokens to raise money.
  3. Salt: Leveraging blockchain assets to secure cash loands. Plans to offer cash loans in traditional currencies, backed by your cryptocurrency assets. Allows lenders worldwide to skip credit checks for easier access to affordable loans.
  4. CHAINLINK: ChainLink is a decentralized oracle service, the first of its kind. Oracles are defined as an ‘agent’ that finds and verifies real-world occurrences and submits this information to a blockchain to be used in smart contracts.With ChainLink, smart contract users can use the network’s oracles to retrieve data from off-chain application program interfaces (APIs), data pools, and other resources and integrate them into the blockchain and smart contracts. Basically, ChainLink takes information that is external to blockchain applications and puts it on-chain. The difference to Aeternity is that Chainlink deploys the smart contracts on the Ethereum blockchain while Aeternity has its own chain.
  5. WTC: Combines blockchain with IoT to create a management system for supply chains Interesting
  6. Ethos unifyies all cryptos. Ethos is building a multi-cryptocurrency phone wallet. The team is also building an investment diversification tool and a social network
  7. Aion: Aion is the token that pays for services on the Aeternity platform.
  8. USDT: is no cryptocurrency really, but a replacement for dollar for trading After months of asking for proof of dollar backing, still no response from Tether.

Market 4 - Privacy

The 4th market are privacy coins. As you might know, Bitcoin is not anonymous. If the IRS or any other party asks an exchange who is the identity behind a specific Bitcoin address, they know who you are and can track back almost all of the Bitcoin transactions you have ever made and all your account balances. Privacy coins aim to prevent exactly that through address fungability, which changes addresses constantly, IP obfuscation and more. There are 2 types of privacy coins, one with completely privacy and one with optional privacy. Optional Privacy coins like Dash and Nav have the advantage of more user friendliness over completely privacy coins such as Monero and Enigma.
  1. Monero: Currently most popular privacy coin, though with a very high market cap. Since their privacy is all on chain, all prior transactions would be deanonymized if their protocol is ever cracked. This requires a quantum computing attack though. PIVX is better in that regard.
  2. Zcash: A decentralized and open-source cryptocurrency that hide the sender, recipient, and value of transactions. Offers users the option to make transactions public later for auditing. Decent privacy coin, though no default privacy
  3. Verge: Calls itself privacy coin without providing private transactions, multiple problems over the last weeks has a toxic community, and way too much hype for what they have.
  4. Bytecoin: First privacy-focused cryptocurrency with anonymous transactions. Bytecoin’s code was later adapted to create Monero, the more well-known anonymous cryptocurrency. Has several scam accusations, 80% pre-mine, bad devs, bad tech
  5. Bitcoin Private: A merge fork of Bitcoin and Zclassic with Zclassic being a fork of Zcash with the difference of a lack of a founders fee required to mine a valid block. This promotes a fair distribution, preventing centralized coin ownership and control. Bitcoin private offers the optional ability to keep the sender, receiver, and amount private in a given transaction. However, this is already offered by several good privacy coins (Monero, PIVX) and Bitcoin private doesn't offer much more beyond this.
  6. Komodo: The Komodo blockchain platform uses Komodo’s open-source cryptocurrency for doing transparent, anonymous, private, and fungible transactions. They are then made ultra-secure using Bitcoin’s blockchain via a Delayed Proof of Work (dPoW) protocol and decentralized crowdfunding (ICO) platform to remove middlemen from project funding. Offers services for startups to create and manage their own Blockchains.
  7. PIVX: As a fork of Dash, PIVX uses an advanced implementation of the Zerocoin protocol to provide it’s privacy. This is a form of zeroknowledge proofs, which allow users to spend ‘Zerocoins’ that have no link back to them. Unlike Zcash u have denominations in PIVX, so they can’t track users by their payment amount being equal to the amount of ‘minted’ coins, because everyone uses the same denominations. PIVX is also implementing Bulletproofs, just like Monero, and this will take care of arguably the biggest weakness of zeroknowledge protocols: the trusted setup.
  8. Zcoin: PoW cryptocurrency. Private financial transactions, enabled by the Zerocoin Protocol. Zcoin is the first full implementation of the Zerocoin Protocol, which allows users to have complete privacy via Zero-Knowledge cryptographic proofs.
  9. Enigma: Monero is to Bitcoin what enigma is to Ethereum. Enigma is for making the data used in smart contracts private. More of a platform for dapps than a currency like Monero. Very promising.
  10. Navcoin: Like bitcoin but with added privacy and pos and 1,170 tps, but only because of very short 30 second block times. Though, privacy is optional, but aims to be more user friendly than Monero. However, doesn't really decide if it wants to be a privacy coin or not. Same as Zcash.Strong technology, non-shady team.
  11. Tenx: Raised 80 million, offers cryptocurrency-linked credit cards that let you spend virtual money in real life. Developing a series of payment platforms to make spending cryptocurrency easier. However, the question is if full privacy coins will be hindered in growth through government regulations and optional privacy coins will become more successful through ease of use and no regulatory hindrance.

Market 5 - Currency Exchange Tool

Due to the sheer number of different cryptocurrencies, exchanging one currency for the other it still cumbersome. Further, merchants don’t want to deal with overcluttered options of accepting cryptocurrencies. This is where exchange tool like Req come in, which allow easy and simple exchange of currencies.
  1. Cryptonex: Fiat and currency exchange between various blockchain services, similar to REQ.
  2. QASH: Qash is used to fuel its liquid platform which will be an exchange that will distribute their liquidity pool. Its product, the Worldbook is a multi-exchange order book that matches crypto to crypto, and crypto to fiat and the reverse across all currencies. E.g., someone is selling Bitcoin is USD on exchange1 not owned by Quoine and someone is buying Bitcoin in EURO on exchange 2 not owned by Quoine. If the forex conversions and crypto conversions match then the trade will go through and the Worldbook will match it, it'll make the sale and the purchase on either exchange and each user will get what they wanted, which means exchanges with lower liquidity if they join the Worldbook will be able to fill orders and take trade fees they otherwise would miss out on.They turned it on to test it a few months ago for an hour or so and their exchange was the top exchange in the world by 4x volume for the day because all Worldbook trades ran through it. Binance wants BNB to be used on their one exchange. Qash wants their QASH token embedded in all of their partners. More info here https://www.reddit.com/CryptoCurrency/comments/8a8lnwhich_are_your_top_5_favourite_coins_out_of_the/dwyjcbb/?context=3
  3. Kyber: network Exchange between cryptocurrencies, similar to REQ. Features automatic coin conversions for payments. Also offers payment tools for developers and a cryptocurrency wallet.
  4. Achain: Building a boundless blockchain world like Req .
  5. Req: Exchange between cryptocurrencies.
  6. Bitshares: Exchange between cryptocurrencies. Noteworthy are the 1.5 second average block times and throughput potential of 100,000 transactions per second with currently 2,400 TPS having been proven. However, bitshares had several Scam accusations in the past.
  7. Loopring: A protocol that will enable higher liquidity between exchanges and personal wallets.
  8. ZRX: Open standard for dapps. Open, permissionless protocol allowing for ERC20 tokens to be traded on the Ethereum blockchain. In 0x protocol, orders are transported off-chain, massively reducing gas costs and eliminating blockchain bloat. Relayers help broadcast orders and collect a fee each time they facilitate a trade. Anyone can build a relayer.

Market 6 - Gaming

With an industry size of $108B worldwide, Gaming is one of the largest markets in the world. For sure, cryptocurrencies will want to have a share of that pie.
  1. Storm: Mobile game currency on a platform with 9 million players.
  2. Fun: A platform for casino operators to host trustless, provably-fair gambling through the use of smart contracts, as well as creating their own implementation of state channels for scalability.
  3. Electroneum: Mobile game currency They have lots of technical problems, such as several 51% attacks
  4. Wax: Marketplace to trade in-game items

Market 7 - Misc

There are various markets being tapped right now. They are all summed up under misc.
  1. OMG: Omise is designed to enable financial services for people without bank accounts. It works worldwide and with both traditional money and cryptocurrencies.
  2. Power ledger: Australian blockchain-based cryptocurrency and energy trading platform that allows for decentralized selling and buying of renewable energy. Unique market and rather untapped market in the crypto space.
  3. Populous: A platform that connects business owners and invoice buyers without middlemen. Invoice sellers get cash flow to fund their business and invoice buyers earn interest. Similar to OMG, small market.
  4. Monacoin: The first Japanese cryptocurrency. Focused on micro-transactions and based on a popular internet meme of a type-written cat. This makes it similar to Dogecoin. Very niche, tiny market.
  5. Revain: Legitimizing reviews via the blockchain. Interesting concept, though market not as big.
  6. Augur: Platform to forecast and make wagers on the outcome of real-world events (AKA decentralized predictions). Uses predictions for a “wisdom of the crowd” search engine. Not launched yet.
  7. Substratum: Revolutionzing hosting industry via per request billing as a decentralized internet hosting system. Uses a global network of private computers to create the free and open internet of the future. Participants earn cryptocurrency. Interesting concept.
  8. Veritaseum: Is supposed to be a peer to peer gateway, though it looks like very much like a scam.
  9. TRON: Tronix is looking to capitalize on ownership of internet data to content creators. However, they plagiarized their white paper, which is a no go. They apologized, so it needs to be seen how they will conduct themselves in the future. Extremely high market cap for not having a product, nor proof of concept.

Market 8 - Social network

Web 2.0 is still going strong and Web 3.0 is not going to ignore it. There are several gaming tokens already out there and a few with decent traction already, such as Steem, which is Reddit with voting through money is a very interesting one.
  1. Mithril: As users create content via social media, they will be rewarded for their contribution, the better the contribution, the more they will earn
  2. Steem: Like Reddit, but voting with money. Already launched product and Alexa rank 1,000 Thumbs up.
  3. Rdd: Reddcoin makes the process of sending and receiving money fun and rewarding for everyone. Reddcoin is dedicated to one thing – tipping on social networks as a way to bring cryptocurrency awareness and experience to the general public.
  4. Kin: Token for the platform Kik. Kik has a massive user base of 400 million people. Replacing paying with FIAT with paying with KIN might get this token to mass adoption very quickly.

Market 9 - Fee token

Popular exchanges realized that they can make a few billion dollars more by launching their own token. Owning these tokens gives you a reduction of trading fees. Very handy and BNB (Binance Coin) has been one of the most resilient tokens, which have withstood most market drops over the last weeks and was among the very few coins that could show growth.
  1. BNB: Fee token for Binance
  2. Gas: Not a Fee token for an exchange, but it is a dividend paid out on Neo and a currency that can be used to purchase services for dapps.
  3. Kucoin: Fee token for Kucoin

Market 10 - Decentralized Data Storage

Currently, data storage happens with large companies or data centers that are prone to failure or losing data. Decentralized data storage makes loss of data almost impossible by distributing your files to numerous clients that hold tiny pieces of your data. Remember Torrents? Torrents use a peer-to-peer network. It is similar to that. Many users maintain copies of the same file, when someone wants a copy of that file, they send a request to the peer-to-peer network., users who have the file, known as seeds, send fragments of the file to the requester., he requester receives many fragments from many different seeds, and the torrent software recompiles these fragments to form the original file.
  1. Gbyte: Byteball data is stored and ordered using directed acyclic graph (DAG) rather than blockchain. This allows all users to secure each other's data by referencing earlier data units created by other users, and also removes scalability limits common for blockchains, such as blocksize issue.
  2. Siacoin: Siacoin is decentralized storage platform. Distributes encrypted files to thousands of private users who get paid for renting out their disk space. Anybody with siacoins can rent storage from hosts on Sia. This is accomplish via "smart" storage contracts stored on the Sia blockchain. The smart contract provides a payment to the host only after the host has kept the file for a given amount of time. If the host loses the file, the host does not get paid.
  3. Maidsafecoin: MaidSafe stands for Massive Array of Internet Disks, Secure Access for Everyone.Instead of working with data centers and servers that are common today and are vulnerable to data theft and monitoring, SAFE’s network uses advanced P2P technology to bring together the spare computing capacity of all SAFE users and create a global network. You can think of SAFE as a crowd-sourced internet. All data and applications reside in this network. It’s an autonomous network that automatically sets prices and distributes data and rents out hard drive disk space with a Blockchain-based storage solutions.When you upload a file to the network, such as a photo, it will be broken into pieces, hashed, and encrypted. The data is then randomly distributed across the network. Redundant copies of the data are created as well so that if someone storing your file turns off their computer, you will still have access to your data. And don’t worry, even with pieces of your data on other people’s computers, they won’t be able to read them. You can earn MadeSafeCoins by participating in storing data pieces from the network on your computer and thus earning a Proof of Resource.
  4. Storj: Storj aims to become a cloud storage platform that can’t be censored or monitored, or have downtime. Your files are encrypted, shredded into little pieces called 'shards', and stored in a decentralized network of computers around the globe. No one but you has a complete copy of your file, not even in an encrypted form.

Market 11 - Cloud computing

Obviously, renting computing power, one of the biggest emerging markets as of recent years, e.g. AWS and Digital Ocean, is also a service, which can be bought and managed via the blockchain.
  1. Golem: Allows easy use of Supercomputer in exchange for tokens. People worldwide can rent out their computers to the network and get paid for that service with Golem tokens.
  2. Elf: Allows easy use of Cloud computing in exchange for tokens.

Market 12 - Stablecoin

Last but not least, there are 2 stablecoins that have established themselves within the market. A stable coin is a coin that wants to be independent of the volatility of the crypto markets. This has worked out pretty well for Maker and DGD, accomplished through a carefully diversified currency fund and backing each token by 1g or real gold respectively. DO NOT CONFUSE DGD AND MAKER with their STABLE COINS DGX and DAI. DGD and MAKER are volatile, because they are the companies of DGX and DAI. DGX and DAI are the stable coins.
  1. DGD: Platform of the Stablecoin DGX. Every DGX coin is backed by 1g of gold and make use proof of asset consensus.
  2. Maker: Platform of the Stablecoin DAI that doesn't vary much in price through widespread and smart diversification of assets.
EDIT: Added a risk factor from 0 to 10. The baseline is 2 for any crypto. Significant scandals, mishaps, shady practices, questionable technology, increase the risk factor. Not having a product yet automatically means a risk factor of 6. Strong adoption and thus strong scrutiny or positive community lower the risk factor.
EDIT2: Added a subjective potential factor from 0 to 10, where its overall potential and a small or big market cap is factored in. Bitcoin with lots of potential only gets a 9, because of its massive market cap, because if Bitcoin goes 10x, smaller coins go 100x, PIVX gets a 10 for being as good as Monero while carrying a 10x smaller market cap, which would make PIVX go 100x if Monero goes 10x.

A block can contain an indefinite number of individual transactions; the limit is only the block size. This is 1 Megabyte (MB). The miners compete for the production of these blocks. The proof-of-work is a cryptographic puzzle that determines which miner is allowed to write the next block into the Bitcoin blockchain. The miners take the transactions (or their Merkle tree) and add a random ...
