Qubit does not have a special design for risk control. It basically adopts a method similar to the mainstream lending agreement Aave. Each mortgageable asset has twbitcoin drop priceo types: LTV (Loan-to-Value, borrowing ratio) and liquidation threshold (Liquidation Threshold). The main parameters, the former determines the upper limit ratio of funds that can be lent for a fixed-value collateral, and the latter determines when the debt/collateral comes to the ratio, the liquidation window will be opened.
Qubit's LTV and clearbitcoin halving date and priceing line parameters (data not updated), source: Qubit documentAt present, the borrowing rate of most assets on Qubit is 60%, which is slightly higher than the initial 50%. While this reduces the risk, it also reduces the pledger's capital utilization efficiency to some extent, especially the mortgage rate of all stablecoin assets is only 60%. There is still a lot of room for optimization of the overall parameters.
In terms of contract security, Qubit only received an audit report from the Peckshield family before it went live in August, which was slightly thin, and the oracle used Chainlink.The total deposits and TVL growth rate of Qubit was very fast since the launch of Qubit. The product's data board function is complete, the product interaction is smooth, and the interface is more beautiful, but overall there are not many innovations. With the continued decline of currency prices and the dilution of subsidies by funds, the current decline in the TVL of the project is also very obvious. It is worth noting that, compared with other lending project tokens that capture the cash flow of the agreement as the core source of value, Qubit's tokens are not currently linked to the project’s profit. The only function is to increase the deposit’s tokens through lock-up. Subsidies, which also caused the intrinsic value of project tokens to weaken, and the high inflation of tokens further aggravated the selling pressure of tokens.Euler is a license-free lending agreement developed on Ethereum founded by Michael Bentley, a researcher at Oxford University. The development company is Euler XYZ. Euler XYZ won the Encode Club’s “Spark” college hackathon in 2020, and subsequently won a $800,000 seed round led by Lemniscap. Other participating funds include LAUNCHub Ventures, CMT Digital, Difference Ventures, Block0 and Cluster. And Luke Youngblood, an influential Coinbase angel investor. On August 25, 2021, the project announced that it has received a new round of investment of 8 million US dollars led by Paradigm. Other investors include Lemniscap and individual investor Anthony Sassano (The Daily Gwei), and Bankless founder Ryan Sean Adams With David Hoffman, Synthetix founders Kain Warwick, Hasu (Uncommon Core podcast).Project FeaturesIn response to the many shortcomings of existing lending projects, Euler has carried out quite a wealth of product mechanism innovations. Due to space limitations, only the key parts are introduced:
License-free listing mechanism: Provide a lending platform for long-tail assetsCompared with the current licensing system adopted by mainstream lending platforms, the introduction of assets on the Euler platform does not require a license, as long as the asset has a WETH trading pair on Uniswap V3. Of course, in order to protect users from low liquidity and the risk of violent fluctuations in long-tail assets, Euler divides assets into three categories based on the risk of assets:1. Combine mortgage rate and borrowing rate to customize the threshold of asset liquidation
Like mainstream lending agreements, Euler requires users to ensure over-collateralization, that is, the value of assets is greater than the value of liabilities. When the value of liabilities exceeds a certain ratio of the collateral, it will allow the liquidator to liquidate the mortgagor's assets and repay the debt. But in the calculation of debt value, Euler also introduced the concept of borrowing factor. The liquidation threshold of each borrower is tailored to the specific risk profile associated with the assets they borrow and use as collateral. In other words, when the value of the borrower's risk-adjusted liabilities exceeds the value of the collateral, it may be liquidated. Specifically, compared to the original lending mechanism, Euler's mechanism also adds a multi-dimensional risk assessment of liabilities, which further improves the safety margin of liquidation.At present, the main liquidation incentive model adopted by mainstream lending agreements such as Compound is: the liquidator can purchase the mortgagor's assets with a fixed percentage discount. Under this mechanism, all liquidators face the same liquidation opportunity, and their potential profit percentages are the same, so they can only compete for liquidation opportunities by increasing Gas, where the high MEV value (Gas cost) becomes the liquidator’s The additional cost also increases the risk of the system. On the other hand, for mortgagors, the fixed asset discount auction rate also allows them to lose the opportunity to lose a lower liquidation penalty.In response to this problem, Euler’s plan is to use Dutch auctions in liquidation, which can ease the joint bid of liquidators and may also obtain lower asset liquidation losses for mortgagors. At the same time, Euler also provides a discount acceleration mechanism for the collateral provider, so that he is eligible to conduct self-liquidation before the liquidator conducts the Dutch auction and reduce the mortgagor's loss. The above two measures are to restrict miners from grabbing excessive MEV fees in the liquidation, so as to improve the overall security of the system in the liquidation storm.In order to further reduce the transaction cost of liquidators in liquidation, Euler also borrowed the stable pool model pioneered by the Liquity protocol and expanded it into a multi-collateral stable pool form, allowing lenders to provide liquidity to the stable pool of each loan market. Support liquidation.
Liquidity providers in the stable pool earn liquidation collateral rewards by depositing eToken (a deposit certificate of the Euler protocol, similar to Compound's cToken). When the liquidation is in progress, the liquidator directly uses the liquidity from the stable pool to repay the debts of the borrower, and will proportionally reward the liquidation collateral obtained to the stable pool, that is, the lender can eventually replace it during the liquidation period. The currency is passively converted into liquidation mortgage assets.For example: Euler provides a stable pool for the USDT that lends assets. The lender who is willing to participate in the stable pool can deposit their own USDT deposit certificate eUSDT into the stable pool as the counterparty of the liquidator, so that the liquidator is auctioning After obtaining the mortgaged assets, the mortgaged assets are replaced with the deposit users of the stable pool at a discounted price (after deducting their own income), which is equivalent to that the users of the stable pool purchase the collateral at a discounted price.
Compared with Liquity which only supports the LUSD stable pool, Euler's multi-token stable pool contains specific types of tokens that have not been disclosed, but it is believed that it will still be based on stable currencies or mainstream currencies.The advantage of adopting this mechanism is that the agreement believes that when the borrower reaches the liquidation threshold, the liquidator can use the internal liquidity source to immediately liquidate, without the need to exchange assets from a third-party trading platform, which greatly eases the liquidator When the market fluctuates sharply, the internal clearing price is inconsistent with the external platform price, and the high transaction slippage causes the liquidator to lose or fail.In addition, Euler does not intend to use an external oracle, but uses the time-weighted average price (TWAP) of assets on Uni V3 and WETH to measure the ratio of assets to liabilities.In the information that Euler has released, it has not disclosed the total amount of its governance token Euler, the distribution method, and the unlocking time. But it has made a preliminary outline of the functions and scenarios of its tokens. Euler will follow Compound's governance paradigm, and its governance functions include the ability to determine the level of assets, important parameters of the agreement, and the framework of governance itself. In addition, Euler also has a Vault mechanism, which can ensure the security of the agreement through staking.
Since the product has not yet been launched, the risk parameters of project assets and other information have not yet been disclosed. In terms of contracts, Euler has officially disclosed three contract security partners, including Certora, Halborn, Solidified, and ZK Labs (the two jointly issued reports), and they have obtained two contract audit reports. Since Euler has introduced more innovative mechanisms, the amount of native code is also large. The issue of contract security is the top priority, and the team still attaches great importance to it.otherEuler is committed to becoming a Uniswap in the lending field, providing lending liquidity and composability for more long-tail assets, and has a strong investor background. The agreement has introduced many innovative mechanisms to address the shortcomings of the current lending agreement, but since the agreement has not yet been launched, the practical effects of these innovations remain to be seen. The project is still not onlineBeta Finance is a decentralized permissionless lending platform incubated by Alpha Finance. Its feature is that users can spontaneously establish currency asset pools, focus on the long-tail asset market, and focus on scenarios where assets are short-selling.
Beta Finance received a strategic investment in July this year. Investors include Spartan Group, ParaFi Capital, Multicoin Capital, DeFiance Capital and Delphi Digital. Generally speaking, the investors have a pretty good background.Last week, I became a consultant for Sushi.com. In the past year, we have gone through a crazy journey, from launching the income farm to migrating more than one billion US dollars from Uniswap to Sushiswap in "Vampire Attack".
When Chef Nomi decided to cash in on the road, he was experimenting with human greed. Many community members not only believed in the initial value from the first day of the project, but also decided to continue to invest in construction desperately. They fell into the abyss and then stood up again.We now have more than 20 core contributors, able to integrate all UI into one, and launch another two protocols Kashi and Miso, which are deployed on more than 10 EVM compatible chains (Polygon, Arbitrum, Fantom, Harmony, xDai, Avalanche, Moonriver and many more). We are trying a new NFT project (http://shoyunft.com/88). Trident has opened the source code a few days ago. I feel confident that the current team can pursue and develop this without me. project.
I will change from day-to-day operations to a consultant role to help cultivate the next generation of teams built on Sushi, support from the side, and help the wider DeFi ecosystem, no matter where they are deployed, it doesn’t matter. I still believe in the Ethereum community, especially after Layer 2 goes live. The most exciting experiments all appeared in Ethereum first. Of course, such exciting attempts are being made elsewhere.I have been working hard to make Sushi a leaderless organization. My role is a contributor. I don't want anyone to recommend any member to the throne and become the so-called "leader" of Sushi. I will encourage decentralization as much as possible. Some things are crucial, such as on-chain governance, recommendation programs for various products (Kashi and Trident!), oSushi guides emissions in a transparent manner, and so on.The liquidity providers of Sushi and ETH, as well as the holders of xSushi, have the best team in the DeFi world to serve them and should be fully utilized.I want to stay in the vault multi-signature group, but if the community does not want this, I will also withdraw after the snapshot vote.I hope the community will not forget:All double reward programs
New agreementSushi is not Maki, and Maki is not Sushi either
MOVR liquid mining project, community members will be responsible for how to operate the funds (0.25% of the supply! Nearly 10 million US dollars at current prices)Support Avalanche Rush Incentives – Polygon – xDai – Celo (our LP's transaction volume exceeds 75 million US dollars)
All funds that join the community believe in this vision of DeFiAmazing items were first launched on Sushi, and will likely continue to be launched here!
Expand this team from 1-2 people to 24 peopleKeep Sushi's fun, open, "Degen", and radically different!The future of France has never been so bright!On a personal level, I put Sushi before physical and mental health, relationships, family and friends. In the next month or two, I will slow down. It must be interesting to build on top of Sushi. Unfortunately, I will not post spam on Twitter. Maybe I will de-anonymize it a bit? Write an in-depth book...Who doesn't want a Hollywood-produced Sushi/DeFi version of "Social Network"? Ha ha. I might divide my BAYC ape into several parts for fun, and then airdrop it to everyone in this community.
After all... We are 0xMaki in some ways, and we have no intention of leaving this space. I have joined the community for a long time, and I am ready to come back when the community needs it. I am a lifetime asset of you.The "two giants" in the game field
In the field of "playing and earning" games, the two most famous projects are Axie Infinity and YGG.Axie Infinity created an unprecedented type of game that is "play while earning", just like "Candy Legend" created the dominance of free games in 2012.
At this stage, Axie Infinity already has more than 1.5 million daily active players, mainly in the Philippines, Indonesia, Brazil, Venezuela, India and Vietnam. For thousands of users, playing Axie Infinity has become their source of livelihood, and sometimes the revenue provided by this game far exceeds their income from working locally. Although most players are not native users in the crypto industry, through viral word-of-mouth marketing, many people have learned about the Axie Infinity game. The explosive growth, global influence, and extensive revenue generation achieved by the Axie Infinity game is indeed impressive. The reason for this achievement is mainly because they created a new game model of "play while earning". In terms of gameplay, Axie Infinity is similar to Pokémon. Players need to breed and breed Axies, a cartoon character that looks like a salamander, and then participate in the battle. The difference is that instead of winning points, the winner gets the game’s native token-Smooth Love Potion (SLP), which can be immediately transferred to another crypto asset or used as collateral, or Cashed as legal tender. Axies and the digital land of games can be bought and sold between individuals as NFTs, and they even launched a governance token (AXS) that allows holders to determine the future of the game.Another project is Yield Guild Games (YFF), which is a "guild" aimed at the new "play while earning" economy. This union is managed by a decentralized autonomous organization (DAO) for those who want to professionally play Axie Infinity and Other people who "play and earn" games provide "scholarship" incentives to share part of their income. Therefore, this decentralized autonomous organization holds NFTs from various Metaverse games, making its governance token YGG an index of game earning economy. Although the project is still in its infancy, there are already more than 4,500 "scholars" with weekly transactions exceeding US$1 million.
In recent months, some other "play while earning" mode games have become more and more popular, such as CryptoBlades, Zed Run, Cometh, REVV, etc. In fact, in the "play while earning" mode games have obtained orders. After the jaw-dropping success, this game revolution is very meaningful for big-name game developers. This trend cannot be ignored, and the futureThe future may see some mature game industry participants begin to incorporate these ideas into their games and bring this game model to a wider audience.Gaming is an industry that covers the world: There are currently more than 2.7 billion gamers in the world, mainly in Asia, Europe and Latin America. In addition, games are firmly integrated into the daily lives of many people: 60% of Americans play video games in some form every day, and video game streaming has 1.2 billion viewers every year. For example, Fortnite is a popular product of Epic Games. Last year, there were more than 350 million live players per month and generated 5.1 billion U.S. dollars in revenue, which shows that even a single game can achieve great success. Some analysts predict that the value of the gaming industry will exceed US$300 billion in the next few years.However, despite the promising development trajectory of the game field, there are still three major shackles:Shackle one, traditional game players don't really "own" anything. Players mainly buy clothing, weapons, props, etc. on in-game items, but even so, last year's consumption in this area still exceeded US$50 billion. However, in addition to improving player performance and game fun, these game items cannot be used for any other purpose, nor can they be sold, lent or mortgaged for any game items purchased by themselves. These purchase transactions are not real investments.
Shackle two, the interoperability between traditional games is very limited. To a large extent, many games on the current market are still walled gardens: they are independent of different "game worlds" and have their own items and experiences. Of course, this problem is not surprising! Game developers want to gain complete independent control over their own creative efforts, but what if game developers can collaborate with each other in more complex ways?Shackle three, traditional games lack business model options. At this stage, more than 80% of total digital game revenue comes from free games (or "freemium games"). In some successful paid games, most of them only get income through the purchase of skins, which will also limit the design space of some developers. Form follows function. As more game developers launch new business models (such as secondary NFT sales commissions), new game forms will also appear.
Why the "Playing and Earning" game can get a big explosionIn fact, there are five major trends that have driven the explosion of "play while earning" games:
Trend 1: The blockchain network continues to expand. Remember the network congestion caused by the "crypto cat" CryptoKitties game in 2017? But now, with the emergence of the second-layer Ethereum expansion protocol, a new high-throughput blockchain, and other scalability solutions, the development of blockchain native games has a solid foundation;Trend 2: NFT becomes mainstream. Many innovations, including the ERC-721 standard, have spawned the recent upsurge in NFT applications. Game companies now have the tools to NFT games, and more importantly, the public can better understand why rare game assets are valuable.
