Crypto-Powered - The Most Promising Use-Cases of Decentralized Finance (DeFi)

Crypto-Powered - The Most Promising Use-Cases of Decentralized Finance (DeFi)
A whirlwind tour of Defi, paying close attention to protocols that we’re leveraging at Genesis Block.
https://reddit.com/link/hrrt21/video/cvjh5rrh12b51/player
This is the third post of Crypto-Powered — a new series that examines what it means for Genesis Block to be a digital bank that’s powered by crypto, blockchain, and decentralized protocols.
Last week we explored how building on legacy finance is a fool’s errand. The future of money belongs to those who build with crypto and blockchain at their core. We also started down the crypto rabbit hole, introducing Bitcoin, Ethereum, and DeFi (decentralized finance). That post is required reading if you hope to glean any value from the rest of this series.
97% of all activity on Ethereum in the last quarter has been DeFi-related. The total value sitting inside DeFi protocols is roughly $2B — double what it was a month ago. The explosive growth cannot be ignored. All signs suggest that Ethereum & DeFi are a Match Made in Heaven, and both on their way to finding strong product/market fit.
So in this post, we’re doing a whirlwind tour of DeFi. We look at specific examples and use-cases already in the wild and seeing strong growth. And we pay close attention to protocols that Genesis Block is integrating with. Alright, let’s dive in.

Stablecoins

Stablecoins are exactly what they sound like: cryptocurrencies that are stable. They are not meant to be volatile (like Bitcoin). These assets attempt to peg their price to some external reference (eg. USD or Gold). A non-volatile crypto asset can be incredibly useful for things like merchant payments, cross-border transfers, or storing wealth — becoming your own bank but without the stress of constant price volatility.
There are major governments and central banks that are experimenting with or soon launching their own stablecoins like China with their digital yuan and the US Federal Reserve with their digital dollar. There are also major corporations working in this area like JP Morgan with their JPM Coin, and of course Facebook with their Libra Project.
Stablecoin activity has grown 800% in the last year, with $290B of transaction volume (funds moving on-chain).
The most popular USD-pegged stablecoins include:
  1. Tether ($10B): It’s especially popular in Asia. It’s backed by USD in a bank account. But given their lack of transparency and past controversies, they generally aren’t trusted as much in the West.
  2. USDC ($1B): This is the most reputable USD-backed stablecoin, at least in the West. It was created by Coinbase & Circle, both well-regarded crypto companies. They’ve been very open and transparent with their audits and bank records.
  3. DAI ($189M): This is backed by other crypto assets — not USD in a bank account. This was arguably the first true DeFi protocol. The big benefit is that it’s more decentralized — it’s not controlled by any single organization. The downside is that the assets backing it can be volatile crypto assets (though it has mechanisms in place to mitigate that risk).
Other notable USD-backed stablecoins include PAX, TrueUSD, Binance USD, and Gemini Dollar.
tablecoins are playing an increasingly important role in the world of DeFi. In a way, they serve as common pipes & bridges between the various protocols.

Lending & Borrowing

Three of the top five DeFi protocols relate to lending & borrowing. These popular lending protocols look very similar to traditional money markets. Users who want to earn interest/yield can deposit (lend) their funds into a pool of liquidity. Because it behaves similarly to traditional money markets, their funds are not locked, they can withdraw at any time. It’s highly liquid.
Borrowers can tap into this pool of liquidity and take out loans. Interest rates depend on the utilization rate of the pool — how much of the deposits in the pool have already been borrowed. Supply & demand. Thus, interest rates are variable and borrowers can pay their loans back at any time.
So, who decides how much a borrower can take? What’s the process like? Are there credit checks? How is credit-worthiness determined?
These protocols are decentralized, borderless, permissionless. The people participating in these markets are from all over the world. There is no simple way to verify identity or check credit history. So none of that happens.
Credit-worthiness is determined simply by how much crypto collateral the borrower puts into the protocol. For example, if a user wants to borrow $5k of USDC, then they’ll need to deposit $10k of BTC or ETH. The exact amount of collateral depends on the rules of the protocol — usually the more liquid the collateral asset, the more borrowing power the user can receive.
The most prominent lending protocols include Compound, Aave, Maker, and Atomic Loans. Recently, Compound has seen meteoric growth with the introduction of their COMP token — a token used to incentivize and reward participants of the protocol. There’s almost $1B in outstanding debt in the Compound protocol. Mainframe is also working on an exciting protocol in this area and the latest iteration of their white paper should be coming out soon.
There is very little economic risk to these protocols because all loans are overcollateralized.
I repeat, all loans are overcollateralized. If the value of the collateral depreciates significantly due to price volatility, there are sophisticated liquidation systems to ensure the loan always gets paid back.

Investments

Buying, selling, and trading crypto assets is certainly one form of investing (though not for the faint of heart). But there are now DeFi protocols to facilitate making and managing traditional-style investments.
Through DeFi, you can invest in Gold. You can invest in stocks like Amazon and Apple. You can short Tesla. You can access the S&P 500. This is done through crypto-based synthetics — which gives users exposure to assets without needing to hold or own the underlying asset. This is all possible with protocols like UMA, Synthetix, or Market protocol.
Maybe your style of investing is more passive. With PoolTogether , you can participate in a no-loss lottery.
Maybe you’re an advanced trader and want to trade options or futures. You can do that with DeFi protocols like Convexity, Futureswap, and dYdX. Maybe you live on the wild side and trade on margin or leverage, you can do that with protocols like Fulcrum, Nuo, and DDEX. Or maybe you’re a degenerate gambler and want to bet against Trump in the upcoming election, you can do that on Augur.
And there are plenty of DeFi protocols to help with crypto investing. You could use Set Protocol if you need automated trading strategies. You could use Melonport if you’re an asset manager. You could use Balancer to automatically rebalance your portfolio.
With as little as $1, people all over the world can have access to the same investment opportunities and tools that used to be reserved for only the wealthy, or those lucky enough to be born in the right country.
You can start to imagine how services like Etrade, TD Ameritrade, Schwab, and even Robinhood could be massively disrupted by a crypto-native company that builds with these types of protocols at their foundation.

Insurance

As mentioned in our previous post, there are near-infinite applications one can build on Ethereum. As a result, sometimes the code doesn’t work as expected. Bugs get through, it breaks. We’re still early in our industry. The tools, frameworks, and best practices are all still being established. Things can go wrong.
Sometimes the application just gets in a weird or bad state where funds can’t be recovered — like with what happened with Parity where $280M got frozen (yes, I lost some money in that). Sometimes, there are hackers who discover a vulnerability in the code and maliciously steal funds — like how dForce lost $25M a few months ago, or how The DAO lost $50M a few years ago. And sometimes the system works as designed, but the economic model behind it is flawed, so a clever user takes advantage of the system— like what recently happened with Balancer where they lost $500k.
There are a lot of risks when interacting with smart contracts and decentralized applications — especially for ones that haven’t stood the test of time. This is why insurance is such an important development in DeFi.
Insurance will be an essential component in helping this technology reach the masses.
Two protocols that are leading the way on DeFi insurance are Nexus Mutual and Opyn. Though they are both still just getting started, many people are already using them. And we’re excited to start working with them at Genesis Block.
https://preview.redd.it/wf1xvq3z12b51.png?width=700&format=png&auto=webp&s=70db1e9587f57d0c470a4f9f4523c216929e1876

Exchanges & Liquidity

Decentralized Exchanges (DEX) were one of the first and most developed categories in DeFi. A DEX allows a user to easily exchange one crypto asset for another crypto asset — but without needing to sign up for an account, verify identity, etc. It’s all via decentralized protocols.
Within the first 5 months of 2020, the top 7 DEX already achieved the 2019 trading volume. That was $2.5B. DeFi is fueling a lot of this growth.
https://preview.redd.it/1dwvq4e022b51.png?width=700&format=png&auto=webp&s=97a3d756f60239cd147031eb95fc2a981db55943
There are many different flavors of DEX. Some of the early ones included 0x, IDEX, and EtherDelta — all of which had a traditional order book model where buyers are matched with sellers.
Another flavor is the pooled liquidity approach where the price is determined algorithmically based on how much liquidity there is and how much the user wants to buy. This is known as an AMM (Automated Market Maker) — Uniswap and Bancor were early leaders here. Though lately, Balancer has seen incredible growth due mostly to their strong incentives for participation — similar to Compound.
There are some DEXs that are more specialized — for example, Curve and mStable focus mostly only stablecoins. Because of the proliferation of these decentralized exchanges, there are now aggregators that combine and connect the liquidity of many sources. Those include Kyber, Totle, 1Inch, and Dex.ag.
These decentralized exchanges are becoming more and more connected to DeFi because they provide an opportunity for yield and earning interest.
Users can earn passive income by supplying liquidity to these markets. It usually comes in the form of sharing transaction fee revenue (Uniswap) or token rewards (Balancer).

Payments

As it relates to making payments, much of the world is still stuck on plastic cards. We’re grateful to partner with Visa and launch the Genesis Block debit card… but we still don’t believe that's the future of payments. We see that as an important bridge between the past (legacy finance) and the future (crypto).
Our first post in this series shared more on why legacy finance is broken. We talked about the countless unnecessary middle-men on every card swipe (merchant, acquiring bank, processor, card network, issuing bank). We talked about the slow settlement times.
The future of payments will be much better. Yes, it’ll be from a mobile phone and the user experience will be similar to ApplePay (NFC) or WePay (QR Code).
But more importantly, the underlying assets being moved/exchanged will all be crypto — digital, permissionless, and open source.
Someone making a payment at the grocery store check-out line will be able to open up Genesis Block, use contactless tech or scan a QR code, and instantly pay for their goods. All using crypto. Likely a stablecoin. Settlement will be instant. All the middlemen getting their pound of flesh will be disintermediated. The merchant can make more and the user can spend less. Blockchain FTW!
Now let’s talk about a few projects working in this area. The xDai Burner Wallet experience was incredible at the ETHDenver event a few years ago, but that speed came at the expense of full decentralization (can it be censored or shut down?). Of course, Facebook’s Libra wants to become the new standard for global payments, but many are afraid to give Facebook that much control (newsflash: it isn’t very decentralized).
Bitcoin is decentralized… but it’s slow and volatile. There are strong projects like Lightning Network (Zap example) that are still trying to make it happen. Projects like Connext and OmiseGo are trying to help bring payments to Ethereum. The Flexa project is leveraging the gift card rails, which is a nice hack to leverage existing pipes. And if ETH 2.0 is as fast as they say it will be, then the future of payments could just be a stablecoin like DAI (a token on Ethereum).
In a way, being able to spend crypto on daily expenses is the holy grail of use-cases. It’s still early. It hasn’t yet been solved. But once we achieve this, then we can ultimately and finally say goodbye to the legacy banking & finance world. Employees can be paid in crypto. Employees can spend in crypto. It changes everything.
Legacy finance is hanging on by a thread, and it’s this use-case that they are still clinging to. Once solved, DeFi domination will be complete.

Impact on Genesis Block

At Genesis Block, we’re excited to leverage these protocols and take this incredible technology to the world. Many of these protocols are already deeply integrated with our product. In fact, many are essential. The masses won’t know (or care about) what Tether, USDC, or DAI is. They think in dollars, euros, pounds and pesos. So while the user sees their local currency in the app, the underlying technology is all leveraging stablecoins. It’s all on “crypto rails.”
https://preview.redd.it/jajzttr622b51.png?width=700&format=png&auto=webp&s=fcf55cea1216a1d2fcc3bf327858b009965f9bf8
When users deposit assets into their Genesis Block account, they expect to earn interest. They expect that money to grow. We leverage many of these low-risk lending/exchange DeFi protocols. We lend into decentralized money markets like Compound — where all loans are overcollateralized. Or we supply liquidity to AMM exchanges like Balancer. This allows us to earn interest and generate yield for our depositors. We’re the experts so our users don’t need to be.
We haven’t yet integrated with any of the insurance or investment protocols — but we certainly plan on it. Our infrastructure is built with blockchain technology at the heart and our system is extensible — we’re ready to add assets and protocols when we feel they are ready, safe, secure, and stable. Many of these protocols are still in the experimental phase. It’s still early.
At Genesis Block we’re excited to continue to be at the frontlines of this incredible, innovative, technological revolution called DeFi.
---
None of these powerful DeFi protocols will be replacing Robinhood, SoFi, or Venmo anytime soon. They never will. They aren’t meant to! We’ve discussed this before, these are low-level protocols that need killer applications, like Genesis Block.
So now that we’ve gone a little deeper down the rabbit hole and we’ve done this whirlwind tour of DeFi, the natural next question is: why?
Why does any of it matter?
Most of these financial services that DeFi offers already exist in the real world. So why does it need to be on a blockchain? Why does it need to be decentralized? What new value is unlocked? Next post, we answer these important questions.

Zhuling Chen
It’s always great to hang out in this group. This group means a lot to the Aelf community. It is the first Aelf community and has been there through all the ups and downs in the world. I would like to start with wishing everyone is staying safe at home during the virus outbreak. It definitely has been a difficult time for all of us, but together we can pull through it.
We understand that the situation is quite striking to all of us. But I really believe that the solution to the virus outbreak is about more global coordination and collaboration.
All of you to be assured, our team in different places are all safe and working from home as normal.
The Aelf team in Beijing were among the early ones experiencing the virus outbreak. As everyone was on the way home for Lunar New Year holiday and then experienced a total city lock-down followed by a 40 days’ work from home policy. It was definitely not easy for them, but our team stayed strong, took necessary precautions and focused on work with the right morale. Mappo has recently published some tips on how to work from home effectively based on our experience. Do check it out. Despite not working in the office since February, we have achieved great progress, including launching Aelf 1.0 preview, which is an important milestone in technical delivery and also the roadmap to mainnet launch (which listed out the essential steps for the community to work together to launch a successful public network)
Let's first talk about Aelf v1.0 preview. It is the cornerstone of the mainnet launch. The product itself has all the features that the public network is needed. The codebase has been reviewed and tested rigorously by the team. And a few highlights of how the network would look like:
  1. The code allows a stable and high throughput blockchain network to operate publicly.
  2. For developers, they will love how flexible the system is to be customized, the number of tools and documentation to help them start developing applications on the network
  3. For the whole community, the system is an ever-evolving one where the voting system is ready in place to conduct network-wide voting on various topics, such as transaction fee adjustment, network protocol upgrade, incentive adjustment, etc
  4. Aelf system is able to run multi-chain architecture where each side chain will host different applications and still ready to work with each other
So you may ask since the software is ready, why have we not yet launched the public network? The answer, in short, is that a public blockchain is launched not by a team but through a community effort and that's why we are coordinating the community effort based on the roadmap we proposed. Aelf team has launched the public testnet based on Aelf v1.0 preview and currently, all nodes are under the team. The goal is to let the community and elected nodes to take it over and launch it on a global scale. Not only launch it but also be familiar with the network and also set the launch parameters in a decentralized way. If we take a car as an example, we have made the car, but ultimately the drivers are you guys and therefore before it really hits on the road, we need to guide the community to do a test drive, adjust the car based on what really works for YOU, and ultimately let YOU drive the car freely and safely
So how are we going to help the community launch the network:
First of all, we have launched the codes, documents about the economic system and governance model and technical features. With all the things available, you are able to understand what the system is about, as a token holder what's your benefit in the system, and being a node in the system plays a big role in the governance
Next, without yet electing the nodes, we will get all token holders to join the current Aelf network through a mapping event. That means as long as you have Aelf tokens, you will be able to get 1:1 test tokens on the public testnet. that gives you full access to all the features, and you will feel like you are already using the mainnet. You will get rewarded in making transactions, voting, etc.
Do try out the Aelf wallet and voting features, you will see how easy to transfer tokens cross-chain. and also how flexible the system allows people to make changes. For example, the community may want to adjust the block rewarding parameters or fees to use certain services on mainnet, they can initiate a discussion and then vote in the system and once voted through, it will be reflected on mainnet.
For people or organizations that want to play a bigger role in the system, we will do a dry run of node election. Take it as the real node election before mainnet launch. We will see who the active members of the community are and being trusted by the community. Among the nodes, we will form a network launch committee. The committee will be the crucial party to oversees and ensures the smooth launch of Aelf mainnet, instead of just relying on the Aelf team. This is our step towards decentralization.
The committee will agree on the actual launch process, final checking all the parameters in the system to be ready for launch and then decide when the criteria are met to launch the network. Once all that is decided. We will invite all interested nodes to apply for the election and let the community know what's their plan to grow the Aelf network. the network will initially be launched with a few nodes from the committee and gradually be replaced by the selected nodes (a bootstrap phase). Along the way, we will work with exchanges to conduct token swap (which we are also designing an innovative system to further enhance security and usability of Aelf tokens in exchanges)
Among this isolated and worrisome time, at least we all have something to look forward to: a successful launch of Aelf network! Once it is launched, we are excited to see a vibrant and technically superior network that is good for Dapps to run on top of it.

Doris Guo Q1: As a Blockchain start-up, what difficulties have you overcome when starting Aelf project? What motivates you to solve difficulties and achieve success today?
Zhuling Chen First, just like launching any start-up, its community and investors are usually regional. There is always some bias on if Asian projects are solid. It is really rare to have an Asian project to be supported by western funds and community from day 1. We were lucky to have overcome that obstacle. Having a global investor line-up from day 1. Having a global team from day 1 and also working with a global community from day 1. This benefited us to have an international perspective which is crucial in the blockchain industry.
Secondly, as a hardcore technology company, it is really hard to put in plain words what is our ambition. Our ambition is huge, achieving key innovations in multiple fronts of blockchain technology and organically combined them to serve real users for the future. Our marketing team has been working really hard to elaborate on what Aelf is. Now we have come to a point that the product is ready. Therefore, it is much easier for all of us to understand how solid Aelf is by trying out the network ourselves! That's exactly what the following events will be about - Try out all the exciting features of Aelf network before mainnet launch.
Doris Guo Q2: What critical problems do you see occurring in the blockchain industry nowadays? How does Aelf solve these problems?
Haobo Ma First, we need to distinguish the difference between BTC and ETH. One is Digital Cash and the other is the Smart Contract Platform. Aelf addresses most of the latter's problems. In short, it can be summarized as performance, end-user friendly, developer-friendly, network economy, and self-governance and upgrading. Each of these areas will probably take up a lot of space, and as a whole are the issues described in our two white papers. In short, Aelf is faster, end-users do not need to know the rules of the blockchain, developers can set up the development environment in 10 minutes, have a good economic model and can carry out proposal governance on the chain.
Doris Guo Q3: What is your long-term vision about the industry which Aelf is working at? Are you afraid someday there will be another project with more innovative technology can replace Aelf?
Haobo Ma Let's talk about where Aelf stands in the traditional Internet. It is essentially a cloud service provider, Aelf provides resources and infrastructure for developers to deploy their services, known as smart contracts. We eventually want Aelf to grow like AAA (Amazon, Azure, AliCloud). Because Aelf is a network that can be dynamically scaled, we can accept any new technology, some of the more advanced technologies we can put on a side chain.
Doris Guo Q4: Why did Aelf choose for cross-chain interaction?
Haobo Ma As I mentioned earlier, Aelf solves the Smart Contract Platform problem. However, there are other digital cash problems as well which we would need to use existing infrastructure such as Bitcoin's chain in order to interact with Bitcoin. There are a lot of infrastructures on Ethereum that we want to interact with. Multi-chain on Aelf network mainly is to isolate resources to improve network performance and network stability.
Doris Guo Q5: What difficulties do the Aelf team have now (I talk about COVID-19)? How does the Aelf team solve it? Have you changed the roadmap?
Haobo Ma There is no great impact. The teams in Singapore and Beijing are communicating with each other remotely on a regular basis. The only change is that most of us are now working from home which has no impact and in fact, it seems conducive to the acceptance of more community developers in the future to come. From the internal working schedule and development timeline, there is no great impact. We do not publish specific timeline as we do not want short term holders (traders) to create too much negative pressure on product development.
Doris Guo Q6: Aelf is an open-source blockchain, and there's the common problem of taking a substantial amount of time for the different participants to agree on strategic decisions. What types of governance models do you use in Aelf to address this issue???
Haobo Ma The issue is about public blockchain network, and who can decide the direction of the network. Our answer is long-term holders. For the short-term holders (traders), we refuse to allow them to participate in any discussion of the direction of Aelf because the short-term holders are likely to make a profit and sell quickly, which is essentially the same example of a person who cheats the President and then runs away for his personal gain. We defined a number of proposal processes, including the logic of the two-party system in the United States, and the participation in the referendum to ensure that the final proposal represents the majority. At the same time, we are looking for some legal solutions to avoid bifurcation, such as prohibiting exchanges from intervening in bifurcated new tokens. While we cannot limit a community, we should be able to find ways to limit a centralized organization. This restriction is akin to a ban on national secession.
Doris Guo Q7: How will Aelf empower Investors, Companies, Developers, Platform Users to deliver impactful solutions and bring value to people all over the world?
Haobo Ma We will learn from the operational experience of successful foundations such as the LINUX foundation and license some commercial companies to use Aelf solutions to solve business problems. At the same time, Aelf is an open-source product under the MIT License, and we accept any use that does not violate this open-source principle.
Zhuling Chen Let me add on to Haobo’s statement: to incentivize and empower the community, we are also exploring ways to let the community decide how to use the funds for Aelf (allocate to where it matters to our community) once mainnet is launched. This means you guys can decide what are the projects to be funded on Aelf, etc
Doris Guo Q8:When will the node campaign start? How will Aelf attract users to participate in nodes election?
Haobo Ma According to our published roadmap, the timeline can be dynamic, but I don't think it will be too long. The main idea is to let everyone understand what we envision Aelf to be like, and what are the rights and benefits of being a node in the future. We hope to find nodes that fully recognize the efforts of Aelf at the present stage and are willing to participate in the future development of Aelf. We will run a simulation of the node campaign on the testnet and set up a temporary mainnet launch committee. Please follow our official Twitter for more upcoming details!
Doris Guo Q9: Token swap form 2 is some kind of cross-chain transfer? It will be handled by a smart contract?
Haobo Ma It is handled by the smart contract, we define an asset cross-chain transfer protocol, but it may be opened after a snapshot.
Doris Guo Q10: Which Exchanges will support token swap? Do you have any plan to list Aelf in some big exchange like Binance, Houbi, Kucoin, .......?
Haobo Ma We are already in talks with some exchanges, there is still competition between exchanges, and many are still hoping to attract more users by getting access to mainnet token swap early.
Doris Guo Q11: Aside conversion of the current tokens to mainnet tokens, what other main features will be accomplished with the mainnet launch?
Haobo Ma We have a documentation file that has been published, which has listed some features: https://Aelf.io/gridcn/Aelf_public_testnet_and_supporting_features_introduction_en_v1.0.pdf
Doris Guo Q12: Do you have any plan to burn or buyback your coin?
Haobo Ma We have plans for the community to govern through DAO, we have no interest in short-term price incentive adjustment as we would prefer to drive the project to higher adoption. After mainnet starts operation, there will be a part of network revenue get destroyed automatically.
Doris Guo Q13: Often, as a newbie developer, I face difficulties on most blockchains. How easy and convenient is it for me on Aelf, and what programming language and tools are needed??
Haobo Ma We set up staging for DAPP developers on GitHub and configured CI. Develop a smart contract using C# with React Native on the front end. So, in fact, developers can fork the source code without setting up the environment locally, and you can conduct unit testing with the help of CI. You can also release the smart contract and generate the installation package of iOS and android online. https://github.com/AElfProject/Aelf-boilerplate
Doris Guo Q14: What is the progress of business development and what are some of your commercial partnerships? How will Aelf rapidly develop the number & performance of DAPP?
Haobo Ma First of all, the blockchain industry is still fairly small and users with ETH and EOS wallets are considered a very small group and its not effective to even promote within these groups. What we need to consider is how to enable users who have never been exposed to blockchain to use DAPP. The competitiveness of Aelf is to make it easier for Aelf developers to promote their DAPP to ordinary users, rather than to teach ordinary users a lot on blockchain knowledge. The average user doesn't like to hear about private keys, mnemonic, Gas Price, RAM, CPU, etc. Only until we solve such problems, companies that need to solve problems through blockchain will be more inclined to use Aelf in technology selection. Therefore, our main work is to explain the competitive advantages of Aelf, ETH and EOS to everyone. We have some business cooperation’s, but we also believe that simply through case-by-case business cooperation will not be able to gain adoption so quickly, therefore we still need to put our products to stay ahead of the next generation.
Doris Guo Q15: What other activities can encourage more people to be confident about Aelf?
Haobo Ma We are only going to state the truth by having those that have faith in us to stay and those that don't to leave. The development of Aelf is not driven by a single foundation, but by a steady stream of contributions from the community. In the future, we will also place the activities in the DAO for on-chain governance, and let the community make decisions by itself.

Kun Aguero As you know that in the present market situation many new coins or either dying or thriving for liquidity? How will you manage this liquidity problem?
Zhuling Chen Aelf started in 2017. we have gone through a few cycles in the market, still, remember the big down period in 2018-2019. Aelf is financially solid and the team has always been working hard. if you are referring to liquidity in exchanges, we are among the lucky ones that are listed in all major exchanges
Xinshu Dong Hello, great discussions! I would like to ask what are the criteria to join the committee for launching the mainnet? Would love to participate
Zhuling Chen Hi xinshu, great to see you here. The committee will be chosen among the nodes elected during the testnet dry run. Which means, it is really important to participate in the testnet dry run and also start to establish your reputation in the community so that people will elect you as a node. The detailed criteria will include what is your plan to help Aelf to grow, tech competency and reputation.
An Da What are Aelf’s achievements in 2019? Who had supported you to get those things?
Zhuling Chen To name a few, in 2019, Aelf is one of the most active projects on GitHub. This means Aelf is evolving and improving fast in this space and our team has the tech strength. In addition, we have also successfully listed on all major cloud service providers, such as AWS, Azure, Google. So large companies can easily launch Aelf side chains in their organization with minimum hassle.
John How does the voting for master nodes candidates occur? And why is the development of this system important for your project?
Zhuling Chen Voting is going to be pretty simple. All token holders can vote for the nodes they support on our block explorer.
Miha After mainnet lunch, how will you assure that transactional fees will stay low? We know what sometimes happens to fees on ETH blockchain.
Zhuling Chen First of all, due to the fact that is Aelf is scalability, this will reduce transaction fee. Secondly, all transaction fees will be voted by the nodes (which will be elected by you). So they will represent your interest
Bobbyfernandito Currently, as we see All projects are concerned with the speed and security. So, tell us here - what are the facilities Aelf provide to their user and investors?
Haobo Ma Security: we have an automated smart contract code audit. During contract deployment, production nodes and the community audit participation are required. On the other hand, we are also planning to provide a standardized model of centralized exchange access for 100% asset certification and emergency measures to deal with exchange attacks, which we will be released later. Speed: Aelf has been working on improving performance, which is transparent to users which they can also experience by themselves.
An Da What effect does Aelf token have on the Aelf ecosystem? Holding Aelf, what benefits will users receive?
Zhuling Chen Holding ELF enables you to use all the services on the Aelf network. ELF has a deflating system where the total amount will reduce as the network grows. token holders can also vote for the nodes to run the network and also vote for big decisions in the network. part of the fees in the system will also be distributed to token holders via a smart contract
ahihi132 Which companies do you view them as potential partners and that they are somewhat also beneficial for both the user base and Aelf itself?
Zhuling Chen Great question, if I could write a wish list, that will be: let medium-sized financial institutions to use Aelf to challenge the big boys. Let telecommunication companies use Aelf for micro-payment and other innovative business models. We also would like to try out a few public sector projects, which blockchain will is still more transparency and trust
Misun Q1: Which programming languages are you using in your project? And why? Q2-What are another big MILESTONES you have planned for 2020 roadmap and how are they supposed to benefit your costumers? Will it be an exciting year?
Haobo Ma For Q1: We mainly use C# for development, I personally like it. Performance is good, development environment IDEs are strong, and C# creators are influential in the industry. We believe in the right thing, though it may take a while to develop. The smart contract will then add support for multiple languages, such as WebAssembly, depending on the needs of the community. Now it seems that C# is enough.
Hambi crypto Which platforms are your competitors? How will you soar above them, and what better things do you offer than them? So, What’s your outlook on the future of cryptocurrencies in this year and next few years?
Haobo Ma As I have already mentioned this before, Eth and Eos. We provide better performance, cross-chain support (already implemented), end-users do not need to know the details of the blockchain, developer’s payment models and so on.
Floris-Jan What plans is Aelf making to prevent centralized exchange to take over the DPoS algorithm like what happened to Steem? Are we talking about blacklisting exchange wallets, or having the foundation say "No", or putting all trust in the community?
Zhuling Chen Great question, Floris. I’m not going to give away all the details of what Haobo has proposed to work on this, but in a nutshell, in Aelf system, exchange wallets will not be allowed to vote, but only the sub-wallets for each individual can vote. This will also help exchanges to prevent hacking and theft in the future
Alex What your plans in place for global expansion, are Aelf wallet focusing on the only market at this time? Or focus on building and developing or getting customers and users, or partnerships? Can you explain this?
Haobo Ma Our core focus will be through the developers to promote, developers will help Aelf to attract more users. So our product has to be attractive to developers. Just like AWS, they only focus on getting their service right, their developers will think about how to promote it. We don't want to burden them in their promotion process.
Ellkay What do you think are the major threats and barriers that could face the development and adoption of Aelf?
Haobo Ma If I'm a DAPP developer and I need to promote my APP to people who don't recognize blockchain, then I'd like to choose a platform that doesn't have to explain a lot of blockchain details to the end-user, so they can use it easily. We've provided some options in the Boilerplate that allow you to log-in simply via QR code + Password, and our recommended Dapp is an independent wallet and a separate iOS/Android application.
ahihi132 Give me some important reasons why we need to hold Aelf token where in fact hundreds of projects failed and it went to bankruptcy or even developers run when they collect millions/billions of funds?
Haobo Ma First of all, we will not give any suggestions as we only describe the fact that the long-term token holder will be able to govern the Aelf network, get Aelf mining reward and Aelf network profit. At the same time, Aelf network is a deflation model, Aelf network received transaction fees, profit dividends will immediately destroy 10% etc. All investments are risky, and we don't judge the behaviour of other developers. There are so many things in this world that cannot be understood and unfair. It is important to do our job well. I cannot explain these things.
见愁 I remember that boss Ma mentioned to only find those truly innovative applications and enterprises with blockchain, how to find and win partners in these aspects?
Haobo Ma When Linus was developing Linux, I did not think he would find a lot of collaboration when the code was not good. The response we can give is that we already have a lot of interest in cooperation, including what we have announced, what we have not announced, etc.
见愁 How interested are cloud computing providers in participating nodes?
Haobo Ma The vast majority of our nodes should be using cloud services, and as long as a large number of our 17 nodes and other candidate nodes are based on cloud services, our network robustness is determined by these cloud computing providers. Of course, in the expansion, we can also use cloud computing services.

Decred Journal – August 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link) to see all the links.

Development

dcrd: Version 1.3.0 RC1 (Release Candidate 1) is out! The main features of this release are significant performance improvements, including some that benefit SPV clients. Full release notes and downloads are on GitHub.
The default minimum transaction fee rate was reduced from 0.001 to 0.0001 DCkB. Do not try to send such small fee transactions just yet, until the majority of the network upgrades.
Release process was changed to use release branches and bump version on the master branch at the beginning of a release cycle. Discussed in this chat.
The codebase is ready for the new Go 1.11 version. Migration to vgo module system is complete and the 1.4.0 release will be built using modules. The list of versioned modules and a hierarchy diagram are available here.
The testnet was reset and bumped to version 3.
Comments are welcome for the proposal to implement smart fee estimation, which is important for Lightning Network.
@matheusd recorded a code review video for new Decred developers that explains how tickets are selected for voting.
dcrwallet: Version 1.3.0 RC1 features new SPV sync mode, new ticket buyer, new APIs for Decrediton and a host of bug fixes. On the dev side, dcrwallet also migrated to the new module system.
Decrediton: Version 1.3.0 RC1 adds the new SPV sync mode that syncs roughly 5x faster. The feature is off by default while it receives more testing from experienced users. Other notable changes include a design polish and experimental Politeia integration.
Politeia: Proposal editing is being developed and has a short demo. This will allow proposal owners to edit their proposal in response to community feedback before voting begins. The challenges associated with this feature relate to updating censorship tokens and maintaining a clear history of which version comments were made on. @fernandoabolafio produced this architecture diagram which may be of interest to developers.
@degeri joined to perform security testing of Politeia and found several issues.
dcrdata: mainnet explorer upgraded to v2.1 with several new features. For users: credit/debit tx filter on address page, showing miner fees on coinbase transaction page, estimate yearly ticket rewards on main page, cool new hamburger menu and keyboard navigation. For developers: new chain parameters page, experimental Insight API support, endpoints for coin supply and block rewards, testnet3 support. Lots of minor API changes and frontend tweaks, many bug fixes and robustness improvements.
The upcoming v3.0 entered beta and is deployed on beta.dcrdata.org. Check out the new charts page. Feedback and bug reports are appreciated. Finally, the development version v3.1.0-pre is on alpha.dcrdata.org.
Android: updated to be compatible with the latest SPV code and is syncing, several performance issues are worked on. Details were posted in chat. Alpha testing has started, to participate please join #dev and ask for the APK.
iOS: backend is mostly complete, as well as the front end. Support for devices with smaller screens was improved. What works now: creating and recovering wallets, listing of transactions, receiving DCR, displaying and scanning QR codes, browsing account information, SPV connection to peers, downloading headers. Some bugs need fixing before making testable builds.
Ticket splitting: v0.6.0 beta released with improved fee calculation and multiple bug fixes.
docs: introduced new Governance section that grouped some old articles as well as the new Politeia page.
@Richard-Red created a concept repository sandbox with policy documents, to illustrate the kind of policies that could be approved and amended by Politeia proposals.
decred.org: 8 contributors added and 4 removed, including 2 advisors (discussion here).
decredmarketcap.com is a brand new website that shows the most accurate DCR market data. Clean design, mobile friendly, no javascript required.
Dev activity stats for August: 239 active PRs, 219 commits, 25k added and 11k deleted lines spread across 8 repositories. Contributions came from 2-10 developers per repository. (chart)

Network

Hashrate: went from 54 to 76 PH/s, the low was 50 and the new all-time high is 100 PH/s. BeePool share rose to ~50% while F2Pool shrank to 30%, followed by coinmine.pl at 5% and Luxor at 3%.
Staking: 30-day average ticket price is 95.6 DCR (+3.0) as of Sep 3. During the month, ticket price fluctuated between a low of 92.2 and high of 100.5 DCR. Locked DCR represented between 3.8 and 3.9 million or 46.3-46.9% of the supply.
Nodes: there are 217 public listening and 281 normal nodes per dcred.eu. Version distribution: 2% at v1.4.0(pre) (dev builds), 5% on v1.3.0 (RC1), 62% on v1.2.0 (-5%), 22% on v1.1.2 (-2%), 6% on v1.1.0 (-1%). Almost 69% of nodes are v.1.2.0 and higher and support client filters. Data snapshot of Aug 31.

ASICs

Obelisk posted 3 email updates in August. DCR1 units are reportedly shipping with 1 TH/s hashrate and will be upgraded with firmware to 1.5 TH/s. Batch 1 customers will receive compensation for missed shipment dates, but only after Batch 5 ships. Batch 2-5 customers will be receiving the updated slim design.
Innosilicon announced the new D9+ DecredMaster: 2.8 TH/s at 1,230 W priced $1,499. Specified shipping date was Aug 10-15.
FFMiner DS19 claims 3.1 TH/s for Blake256R14 at 680 W and simultaneously 1.55 TH/s for Blake2B at 410 W, the price is $1,299. Shipping Aug 20-25.
Another newly noticed miner offer is this unit that does 46 TH/s at 2,150 W at the price of $4,720. It is shipping Nov 2018 and the stats look very close to Pangolin Whatsminer DCR (which has now a page on asicminervalue).

Integrations

www.d1pool.com joined the list of stakepools for a total of 16.
Australian CoinTree added DCR trading. The platform supports fiat, there are some limitations during the upgrade to a new system but also no fees in the "Early access mode". On a related note, CoinTree is working on a feature to pay household bills with cryptocurrencies it supports.
Three new OTC desks were added to exchanges page at decred.org.
Two mobile wallets integrated Decred:
Reminder: do your best to understand the security and privacy model before using any wallet software. Points to consider: who controls the seed, does the wallet talk to the nodes directly or via middlemen, is it open source or not?

Adoption

Merchants:

Marketing

Targeted advertising report for August was posted by @timhebel. Facebook appeal is pending, some Google and Twitter campaigns were paused and some updated. Read more here.
Contribution to the @decredproject Twitter account has evolved over the past few months. A #twitter_ops channel is being used on Matrix to collaboratively draft and execute project account tweets (including retweets). Anyone with an interest in contributing to the Twitter account can ask for an invitation to the channel and can start contributing content and ideas there for evaluation by the Twitter group. As a result, no minority or unilateral veto over tweets is possible. (from GitHub)

Markets

DCR started the month at USD 56 / BTC 0.0073 and had a two week decline. On Aug 14 the whole market took a huge drop and briefly went below USD 200 billion. Bitcoin went below USD 6,000 and top 100 cryptos lost 5-30%. The lowest point coincided with Bitcoin dominance peak at 54.5%. On that day Decred dived -17% and reached the bottom of USD 32 / BTC 0.00537. Since then it went sideways in the USD 35-45 / BTC 0.0054-0.0064 range. Around Aug 24, Huobi showed DCR trading volume above USD 5M and this coincided with a minor recovery.
@ImacallyouJawdy posted some creative analysis based on ticket data.

Relevant External

StopAndDecrypt published an extensive article "ASIC Resistance is Nothing but a Blockchain Buzzword" that is much in line with Decred's stance on ASICs.
The ongoing debates about the possible Sia fork yet again demonstrate the importance of a robust dispute resolution mechanism. Also, we are lucky to have the treasury.
Mark B Lundeberg, who found a vulnerability in atomicswap earlier, published a concept of more private peer-to-peer atomic swaps. (missed in July issue)
Medium took a cautious stance on cryptocurrencies and triggered at least one project to migrate to Ghost (that same project previously migrated away from Slack).
Regulation: Vietnam bans mining equipment imports, China halts crypto events and tightens control of crypto chat groups.
Reddit was hacked by intercepting 2FA codes sent via SMS. The announcement explains the impact. Yet another data breach suggests to think twice before sharing any data with any company and shift to more secure authentication systems.
Intel and x86 dumpsterfire keeps burning brighter. Seek more secure hardware and operating systems for your coins.
Finally, unrelated to Decred but good for a laugh: yetanotherico.com.
