zkSync challenges: generating zero-knowledge proofs requires a lot of computing resources, and the eth price january 2021hardware threshold for zkSync verifiers is relatively high; it is difficult to implement general smart contract functions (this is a problem that all adopters of ZK Rollup solutions currently face).
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 arebuy bitcoin kucoin 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.For example, in the POW chain, when mining pool A is attacked or there is a problem with the node, in theory, the block generation speed on the chain will be greatly reduced at this time. A block in the previous 10 minutes may now take 15 minutes on average, unless it is time to adjust the difficulty. , But for miners, they can cut their own computing power to other mining pools, which completes the redistribution process of computing power. The mining pool's computing power is reshuffled without affecting the efficiency of the overall network, and blocks are generated. The time will soon return to the previous 10 minutes, which completes the adaptive adjustment of the network.
Therefore, the impact of attacking a certain mining pool node of Bitcoin and Ethereum on the network is relatively small, so why does the POW network not improve the efficiency of the chain?In fact, this is mainly because the POW chain requires a large number of calculations to determine the hash value, which increases the difficulty of tampering and forks to a certain extent, thereby ensuring security, although the current block generation speed of some POW chains is also Increase, but we can clearly compare the problem that may exist when the speed increases, that is, the problem of easy bifurcation.Bitcoin is a block in 10 minutes, and it is not easy to forkEthereum has a block in about 13 seconds, and sometimes an uncle block is needed to ensure that the transaction does not forkA public chain with a higher block generation rate has a block every two seconds. Except for the uncle block, there is a certain rejection rate when mining to ensure that there is no fork.
The faster the chain, the higher the possibility of forking. Therefore, in order to ensure a complete chain, it can only bring a higher rejection rate or try to ensure the computing power while increasing the ability to perform multitasking at the same time. The fork will soon be strangled into the cradle.For non-POW public chains, this does not happen, because they no longer need to rely on competition to ensure their own block qualifications, some are in turn, and some are random, so that they wait until the node has a block. In the case of block qualification, only a small amount of computing power is required to successfully generate eligible blocks. Because of this, the non-POW public chain itself can have high block generation efficiency, and most of the resources will be used above the block generation speed.Mainstream lending platforms only support mainstream assets, the range of options is small, and the price fluctuations of mainstream assets are small, and the potential for short-selling is insufficient
Beta Finance fits the needs of users on these two points.First of all, it provides a one-click short-selling interface for short sellers. Users can quickly select their short-selling collateral and short-selling objects. Beta will automatically borrow the corresponding short assets through its own currency market and sell short on the selected DEX. , And then the assets obtained from the sale will continue to be included in the collateral to reduce risk. In this process, users do not need to interact with multiple protocols, thus saving high gas fees and avoiding rushing in the face of sudden market opportunities.In addition to the improvement of the short-selling experience and the reduction of costs, Beta Finance's permissionless features and product positioning focusing on long-tail assets also mean that there will be more non-mainstream assets available for short-sellers on Beta Finance in the future. These non-mainstream assets often have more extensive short-selling or hedging needs.We have seen that despite the short launch time of the product, the TVL of the project has risen rapidly. On the one hand, Alpha endorsed the project. On the other hand, the official also publicly stated that subsequent airdrops will be carried out for deposit and borrowing and short-selling users. The project brought in a lot of funds. However, the utilization rate of Beta Finance funds is currently low.
Among all the listed assets, USDC ranks first in deposit volume and capital utilization rate.We found that because Beta is in the first stage of its launch, 16 of the assets are all certified assets (Verified Markets) that are officially reviewed and rated. Among them, the only asset of Risky Markets is Feisty Doge NFT's fragmented token NFD. , NFD is an ERC-20 ownership token after the Feisty Doge NFT (Dogecoin prototype NFT) is split on the NFT fragmentation protocol Fractional. It is a typical long-tail asset and it is also the main asset type that Beta Finance wants to support in the future. .
Beta Finance's product functional interface style is simple, the layout is reasonable, the interactive design also conforms to the user's intuition, and it is easy to use. On each business function page, the data display is also quite detailed, which is reassuring.At present, the project has not issued any tokens, nor has any information related to the total amount of tokens and distribution methods found on the official website, nor has it described the usage and scenarios of the tokens.It is expected that the detailed token model will not be disclosed until the tokens start to be distributed.risk control
Beta Finance will classify certified assets (Verified Markets), with the highest level being S level (three stable coins), followed by ETH and WBTC being AA level. Different levels of collateral correspond to different lending rates (LTV) and liquidation line parameters, but currently only ETH and three stable coins are supported as collateral.Beta Finance's certified asset level and corresponding risk parameters, source: Beta Finance documentIt is worth mentioning that Beta Finance also disclosed the classification logic and model of certified assets. The evaluation dimensions include smart contracts of assets, counterparties and transactions of assets, which are very detailed.In terms of smart contracts, Beta Finance has obtained reports from Peckshield and OpenZeppelin, two audit institutions, and has launched a Bug bounty program in cooperation with Immunefi.
On the whole, Beta Finance's security preparations are relatively complete.Summarize
Beta Finance has accurate product positioning and business scenarios, focusing on long-tail asset lending and short-selling services, which is a distinct difference from the existing large-scale lending platforms. Its product concept is concise, and the functional combination of long tail assets + one-click shorting also has a large market growth space. In addition, Beta Finance's investor background is quite good. Although the project has not officially started the token distribution and has not announced the token model, it deserves long-term attention.Project Status
Product launch time: August 19, 2021Benqi is the first native lending agreement on Avalanche, led by Ascensive Assets, with participation from Dragonfly Capital, Spartan Group, Ava Labs, GBV Capital and other institutions. Benqi's current products are similar to most mainstream lending platforms, adopting the borrowing model of a pool of funds, and all product mechanisms are quite satisfactory, without much innovation.Project FeaturesAs mentioned above, Benqi itself does not have much innovation in mechanism. Its TVL soaring comes from first-mover advantage on the one hand, and from the 3 million US dollar liquidity mining jointly launched by Benqi and the Avax Foundation on the other hand. In addition to mining subsidies, Benqi itself will also distribute project tokens QI to the users of the agreement as a reward. The total monthly subsidy amount exceeds 10 million U.S. dollars.Business conditionsBenqi is the largest project in the avalanche protocol ecology. According to data from DeFi Llama, its TVL has accounted for 47% of the total TVL of the avalanche protocol.
We can find that Benqi's high total funds and capital utilization rate are largely due to the higher token subsidies at the current stage.Product UI/UX
Benqi's product interface is relatively simple and quite satisfactory. Compared with Qubit and Beta Finance, it displays less data and still has room for improvement.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. 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.Blockchain News, September 18 The intersection of blockchain and games will undoubtedly become a hot topic in many industries in the future-there are actually many similar topics. But in this field, there is a new trend that is very interesting, that is, play and earn (P2E) games.
The "two giants" in the game fieldIn the field of "playing and earning" games, the two most famous projects are Axie Infinity and YGG.
