【bitcoin drop reddit】

I put on VR goggles, completed a quick tbitcoin drop redditutorial, and took a breath when I found myself standing on top of a skyscraper.

This means that in some characteristics, the price of bitcoin has risen, and there are more shippers, so more USDT is exchanged through the acceptor, and the acceptor will continue to reduce the U price.solana solar farmIn the stable currency trading market, buying and selling USDT will definitely show different prices. The spread is the profit of the acceptor.

This income method will also be used as the core business of many wallets, mainly in the compliance area to complete the sale of cash to stablecoins and tokens such as Bitcoin and Ethereum.With a huge total transaction volume, the wallet can earn huge profits by charging fees.So as long as there is a variable of acceptor in the stable currency market, the price of stable currency must fluctuate up and down. But because if the stable currency in the exchange trading pair is a legal currency anchored stable currency, it may not need to carry too much floating risk. But in the process of transaction, tokens are directly exchanged for legal currency value.It is also because, for example, USDT is a stable currency token between tokens and fiat currency, and the exchange market of USDT is a floating market, which brings about the unstable price performance of stable currency that users understand.What about designing a stable coin to make the price the most stable design?

The answer should be no, because as long as it is a stable currency issued and accepted by a trusted subject, the absolute stability of the price cannot be guaranteed, and the absolute stability of the price also means that there is no market profit margin, and it is impossible to develop a perfect business ecological structure. For example, if the ratio of USDT to U.S. dollar has no price fluctuations. The user using US dollars is the same as using USDT.The result of this is that there is no spread when the acceptor buys and sells USDT. In other words, in the exchange, there is no need to introduce an over-the-counter market, but a stable centralized exchange pool can be established directly by the acceptor. However, the most suitable role for establishing an exchange pool is the exchange itself.Total and supply

The 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 documentThe 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 accelerationUp 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 onlineEuler 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.

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 pricingThis 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.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 exchanged to 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 collaborated to issue 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.

Euler 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. There is still no clear timetable for the launch of the project, but the administrator of the Chinese community Chris (Mr. the well-known encrypted KOL block) said that more news may be disclosed in September.Product launch time: August 17, 2021
