Stable currency is an important role in the cryptocurrency world and a bridge between cryptocurrency and real finance.cardano coinbase when Today's stablecoin scale continues to rise, which is one of the important growth signals of the cryptocurrency market. The maturity of stablecoins has reason to become one of the necessary conditions for the growth of cryptocurrencies.

However, this incident has given many people a thought as to what kind of public chain we need in the future.xrp price live tickerOn the one hand, POW-type mining public chains such as Bitcoin face the problem of low TPS and cannot carry the high-demand transactions of the existing DEFI. On the other hand, chains such as Solana, fantom, and polygon are facing a tendency to become more centralized. When there is a peak, the network becomes unstable, and even this kind of network is paralyzed. However, it seems that there is still no good solution to get the advantages of both at the same time.

Why is the high TPS public chain unstable?Many people may have heard of the "Impossible Triangle" in the currency circle, that is, high performance, security and decentralization are not available at the same time. Security is one of the main directions at present, so high performance and decentralization It becomes the opposite, and solana mainly improves the transmission rate, that is, performance, so there are naturally certain shortcomings in decentralization.However, this situation does not hurt a lot in the bull market. The rise of DEFI in the bull market is still based on practicality. Solana is obviously more practical, so this does not prevent capital from paying attention to it.But for other high-performance public chains, they may all face similar problems. When the user group's sentiment is high, the transfer on the chain reaches the upper limit of the load, and there is no certain protection measure, then the network may collapse, and Solana has funds. Yes, even if it collapses, the currency price is still relatively stable, and it has not fallen much. On the contrary, it shows that the ecological development is successful and the user participation is high. Compared with other public chains, if it collapses, can you still have such good luck? Probably not.The POW chain still maintains good network security and decentralization

For the early POW chains, their decentralization is still relatively high, such as Bitcoin, Litecoin, and Ethereum. The degree of decentralization of the network mainly depends on the decentralization of the true owners of computing power. Many people mistakenly believe that the current Bitcoin mining pools account for a large percentage of the computing power of the mining pool. If the mining pool is attacked, it is equivalent to the block producer being attacked, which will affect the network security. To a certain extent, this view is still partially flawed.The computing power we are talking about is mainly based on the actual autonomous distribution rights of users, rather than the operating status of the block node. For example, most mining pools are actually running in professional computer rooms. The computing power of mining pools is high. To a certain extent, it will lead to centralization, but the mining power of an individual can change at any time. That is to say, the mining rights of the mining pool are the result of the choice made by the miners, and this choice can be changed instantly. For example, cutting off computing power is also a matter of minutes. Non-POW nodes have to undergo a series of processes such as reselection and voting, which also delays a certain amount of time. Therefore, POW is relatively advantageous.In terms of the type of lending business, whether it is the number of projects or the amount of funds, basic lending projects account for a higher proportion, followed by leveraged mining lending projects, and other relatively new ones such as risk-graded interest rate products. The business volume is currently relatively small.

This research report will focus on newly born lending projects in the past 1-2 months with rapid business growth (TVL has entered the top 15 lending category), and Euler, a project with many innovative combinations in mechanism.The following is a detailed analysis and analysis of each item.In the combing and analysis part, the author will present and analyze the product positioning, project characteristics, business conditions, token model and risk control of the four projects, in order to analyze these four emerging lending projects as a whole as possible.Basic lending platform

Qubit is a decentralized currency market that uses a mainstream borrowing capital pool model. Qubit's development and operation team is the team behind Pancakebunny-Mound, which was first deployed on BSC, and there are plans for multi-chain expansion in the future.Project FeaturesThe main features of Qubit compared to other basic lending projects are:Its token QBT can increase the rate of return of deposit users after lock-up, which is called "Boost" function

Qubit is part of Mound’s product matrix, and Mound’s products are highly combinableQubit does not support lightning loan functionBusiness conditionsBusiness 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 Features

In 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.
