In fact, this is mainly because the POW chain requires a large number of calculations to determine the hash value, which increases the diffichainlink oracle feesculty 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.

I will change from day-to-day operations to a consultant role to help cultivate the next generation of teams bdid ethereum difficulty changeuilt 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 programsNew agreement

Sushi is not Maki, and Maki is not Sushi eitherMOVR 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)Trend 4: Web2 interoperability. Many traditional large-scale technology giants have also begun to join the decentralized ecosystem, and have also opened up a new distribution mechanism for encryption-driven games. For example, Apple’s recent changes to the App Store can make it easier for iOS users to directly access NFT-based “sides”. Play and earn” game.

Trend 5: Metaverse. "Meta universe" has become a new frontier of digital experience, and the rapid rise of this emerging concept has even aroused Facebook's interest.SummarizeThis summer, Axie Infinity achieved explosive growth, and many people were also very excited about Yield Guild, which in turn promoted the flourishing of "play while earning" games. After this craze, traditional game giants and cryptocurrency thought leaders have also begun to pay attention to "play while earning" games-under this strong tailwind, what other projects will be built in the future is very worthy of attention. For investors exploring the field of "playing and earning" games, now is of course a very "fun" moment, but from a broader perspective, it also marks the occurrence of our views on labor, leisure and value Changes-therefore, the "play and earn" game is definitely an important trend we must pay attention to.If you say which one is the most brilliant chain in the second half of this year, there is no doubt that solana is worthy of its name. SOL was founded by former Qualcomm, Intel and Dropbox engineers at the end of 2017. Solana is high-performance, fast, generous and rich in the project, and the team has SBF. Blessing, these distinctive features have enabled solana's defi to be launched one after another since May, and reached a blowout level. This is mainly due to the continuous development of the market and ecology of solana, and three consecutive hackathons were held within a year. Most of the projects have been effectively incubated. Obviously, Solana's reputation has overtaken polkadot and become a new public chain giant.

The specific situation is actually very simple. The ecological project parrot conducts IDO. According to official regulations, users can receive tokens when IDO is completed, and then they can trade at the same time. On the one hand, the enthusiasm for participation is high and the user base is large. Most people wanted to sell at a high price for the first time, which caused congestion on the chain and data overflow and collapse of most nodes. In the end, the network was paralyzed for more than ten hours. It can be said that similar incidents are almost hard to come across.On the one hand, the enthusiasm of users is indeed too high. On the other hand, the high-performance public chain also faces the risk of being questioned. Fortunately, after the official team released the new version of the program, the solana network returned to normal and everyone can continue to play.

However, this incident has given many people a thought as to what kind of public chain we need in the future.On 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 decentralizationFor 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.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.The future Ethereum 2.0 adopts the method of sharding. In fact, it decentralizes the rights of nodes and realizes another mode of decentralization as a whole. However, from the perspective of each shard chain, it is still It is relatively close to centralization, so just like others' laughter, most public chains run in centralized computer rooms. As long as the computer room is powered off, the public chain can die for a large amount of time. It is biased, but it can show that there is still a long way to go in the exploration of public chains.

In the investor letter in the first quarter of 2021, the asset management company Polen Capital had increased its selling of some stocks, and LendingTree, Inc. was among them."We also emptied LendingTree's position. LendingTree is a two-sided market in the consumer financial services vertical that connects borrowers and lenders. The company has established a brand for more than 15 years, and it has borrowed money by letting banks compete. People provide savings. The company was acquired by IAC before the financial crisis and then spun off at the height of the global financial crisis. The company re-emerged by increasing the value of the mortgage market after the global financial crisis. The company used it. The strong cash flow generation in the model expands to neighboring regions and diversifies the income base. Over the years, product supply has been expanded mainly through acquisitions, including credit cards, personal loans, and insurance. This diversification strategy has benefited from demand shocks , Such as the decline in mortgage demand 18 months ago, and then the demand disruption caused by the pandemic. However, diversification also has some drawbacks. Although it can protect the company from major demand disruption shocks, in our view, with As the product is favored due to macro factors, it is also difficult to promote sustained long-term compound interest. Although we believe that LendingTree has solved a unique problem, we don’t think it has the same compound interest potential in the future."
