In the past five months, ARK's funds have solethereum wallet tutoriald more than 1 million shares of Tesla stock. But Tesla is still one of its heavyweights.
This project was very attractive, and soon the virtualwhat does kusama coin do world began to expand. Pandapops completed her aquarium, put it in a tavern, and then inserted the tavern into a village she created, enclosing it in a forest.There are people everywhere in the village, and she is designing a game. "This guy hasn't given us a task yet, but he will," Pandapops said of the bartender. Like all the small characters, he looks a bit like a character in a Lego movie. "That's a bounty hunter," she said. Soon we saw our protagonist, the well-known "Player One", who was jogging through the courtyard with a cute little sword.
Pandapops is not a professional game designer. She is not an employee of Epic, Sony or Electronic Arts. She is using a program called VoxelEdits to create a game for the sandbox. The sandbox is a meta-universe based on blockchain technology. The game launched its public version 1 in late September.According to the company's co-founder and COO Sebastien Borget, even before the launch of Metaverse, the sandbox's Game Maker engine (currently in beta) has been downloaded more than 100,000 times. "Our Game Maker does not require code, and you can make games without any experience," Borget said. "This is what we have been building for more than three years."They have actually been built for 10 years. Sandbox was originally launched in 2011 as an ordinary non-blockchain startup, representing a shift from traditional games to encrypted games. Sandbox was originally a mobile application. Borget said that although the app has been downloaded 40 million times, "the success of the game comes from users." These users have created 70 million assets, which is common in traditional games such as Minecraft and Roblox. After Borget learned about the strong market for CryptoKitties, CryptoPunks, and NFT users, he flipped the sandbox model to a decentralized blockchain meta-universe, which enabled “turning players into creators” and then “helping players and creating People monetize all the content they produce."For non-blockchain enthusiasts, meta universe is still an obscure concept. This may change soon. The New York Times is running the meta-universe interpreter; traditional brands such as Sotheby’s and Coca-Cola are entering the meta-universe; perhaps most importantly, Zuckerberg is linking the future of Facebook with the meta-universe. He told employees in the summer, The company's primary goal is to "bring the virtual world to life."This begs the question, what exactly is the meta universe? Is it just one platform, or the sum of all platforms? Ask 10 different people in an encrypted meeting and you will get 10 different definitions. Venture capitalist Matthew Bauer wrote: "We should not expect to have a single and comprehensive definition of'meta universe'." "Meta universe is best understood as a'further development of the mobile Internet'. This is because of the meta universe. The universe will not fundamentally replace the Internet, but iteratively transform on its basis."
Maybe today and tomorrow, Metaverse is just an online virtual world—like Decentraland, Crypto Voxel, and The Sandbox—where you can play fast games, browse NFTs in art galleries, or hold online parties. This is the initial stage of the meta universe. But after 5, 10, or 20 years, Metaverse may replace most of the work you do online or even offline.What path will we take to realize the future of this meta-universe? Centralized technology route through Facebook? Or through a new decentralized model? As the NFT artist "6529.eth" asked in a viral Twitter thread, "What we are playing is whether our children will be completely immersed in the digital world in the future-there is an illusion of freedom, but not true freedom ."Business data
Qubit's core business data are as follows:We can find that although Qubit's project has been online for less than a month, it currently has a considerable amount of deposits and the utilization rate of funds is relatively high. This is related to Bunny's previous accumulation of a large number of BSC users and the relatively high amount of token subsidies for the project. Currently, QBT's single-day subsidy amount is around US$190,000.Product UIUXQubit's product UI style is simple and clear, the interaction is smooth, the display of key data is reasonable and detailed, and the overall user experience is better.
Qubit product main interface, https://qbt.fi/appMoreover, the current business data and risk parameters of Qubit's specific assets are very detailed, and graphically processed, and there are some historical data available for checking, which is worthy of recognition.
Token modelTotal and supplyThe total amount of QBT is 1 billion, of which 57% is used for liquid mining rewards, and the remaining 43% is controlled by the team. The specific distribution ratio is as follows:QBT distribution ratio, source: Qubit project document
The total amount of 1 billion QBT will be distributed within one year, so QBT will face very high inflationary pressure in the next 12 months. The specific token unlocking rhythm is as follows:In my opinion, there are two core problems in the supply and release mechanism of Qubit tokens:The proportion of team control is relatively high, and most of them have not set strict token unlocking conditions, and the long-term binding of team interests and projects is insufficientThe tokens of the liquid mining part are released too fast, which may cause the project to lack sufficient subsidy budget after one year, which is not conducive to the long-term development of the project
Token value captureCore function: revenue acceleration
Up to now, the main function of QBT is to obtain qScore after lock-up. Through qScore, deposit users can accelerate their deposit income (from the increase in QBT deposit subsidies).This mechanism is similar to Curve's Locker mechanism. Curve's Locker function and economic model consolidate its original competitive advantage and increase the switching cost of liquidity providers and investors. It is a very eye-catching design. However, when the mechanism is applied to a loan agreement, will it still have a good effect? The author remains skeptical about this.
First of all, the reason why some people are willing to lock up the position of Curve's token CRV for a long time after buying it is caused by Curve's strong position in the stable asset business chain and the competition for the governance power of Curve by multiple participants. Because governance power on the Curve platform means two core resources: the baton of liquidity and the accelerator of revenue.Since the issuer of stable consideration assets (stable currency, stETH and other pledge certificates and BTC cross-chain assets such as renBTC are all stable consideration assets), they have great requirements on the stability and transaction depth of their operating assets, so they choose Curve to list. Assets and attracting market-making liquidity are very rigid requirements, which creates a strong position of Curve relative to asset operators, which is determined by the business positioning of its Top1 stable asset exchange platform.In terms of the expansion of asset lending scenarios, the demand from asset operators is far less strong, which has led to a large number of less demanders of Qubit governance rights, and the overall lock-up willingness is difficult to reach the level of Curve.In addition to the revenue acceleration function, QBT currently has no other functional scenarios. The Qubit platform's loan interest spread income does not have QBT's repurchase or dividend mechanism.On the whole, QBT tokens are currently weak in capturing the overall economic value of the platform.risk control
Qubit does not have a very special design for risk control. It basically uses a method similar to the mainstream lending agreement Aave. Each mortgageable asset has two types: LTV (Loan-to-Value) 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.However, the current borrowing ratio of all Qubit assets is the same as the liquidation line, instead of Aave's method of using the liquidation line to be higher than the borrowing ratio.
At 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. As the currency price continues to fall and subsidies are diluted by funds, the current TVL decline of the project is also very obvious. It is worth noting that, compared to other lending project tokens whose core value source is to capture the cash flow of the agreement, Qubit's tokens are not currently linked to the project's profit. The only function is to increase the deposit of 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.Product launch time: not online
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 founder 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 assets
Compared 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:Isolation layer assets: Users can deposit or lend assets, but they cannot use the isolation layer assets as collateral. In addition, if you want to borrow different isolation layer assets, users need to use different accounts on Euler to isolate different assets Between the risks.
Cross-layer assets: It can be used for ordinary lending and cannot be used as collateral, but it is possible to borrow multiple cross-layer assets with one account.Mortgage layer assets: The assets of this layer are similar to those of most mainstream lending platforms. They can be used for ordinary lending, cross-borrowing, or as collateral. Cross-borrowing means that users mortgage assets in one account to borrow multiple mortgage-level assets.
By isolating assets with different risk levels, Euler attempts to increase the supported asset classes on the one hand, and on the other hand to ensure that high-risk assets do not affect the security of mainstream assets.Adopt dynamic interest rate model: improve the sensitivity and accuracy of interest rate pricing
This model is similar to the "dynamic interest rate model" designed by Delphi Digital for the Mars Protocol, the lending agreement of the Terra ecology. On the one hand, it improves the sensitivity and accuracy of interest rate pricing, and at the same time, it can obtain higher interest income for depositors and the agreement itself.To put it simply, the interest rate model is adjusted on the basis of mainstream lending agreements such as Aave. By adjusting the fund utilization formula, the interest rate can be more sensitively adapted to the real capital supply and demand situation of the market in real time, instead of the existing mainstream interest rate. The linear method of the model increases the interest rate. This can prevent the occurrence of a loan agreement that can only watch users use low-cost borrowing on their own platform and then deposit to other platforms to obtain high mining revenues for arbitrage. This will cause borrowers to have no incentive to provide loans, and lenders are unwilling The situation of repayment as soon as possible eventually led to the exhaustion of the liquidity of the loan agreement. The dynamic interest rate model is dedicated to solving such problems.For details of the Euler interest rate dynamic model, please refer to "Introducing Euler" in the reference material.A large number of improvements in the liquidation mechanism: optimization of the liquidation threshold, anti-MEV, internal multi-collateral pool
1. Combine mortgage rate and borrowing rate to customize the threshold of asset liquidationLike 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 ratio 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. Passive exchange of currency into liquidation mortgage assets.
