On November 25th, Vitalik, the co-founder of Ethereum, said in an interview with Tencent's "Perspective" that he is worried that if the particularly intelligent people do not do Crypto, the people who stay in the Crypto field may not have any interesting ideas, and the only application is the financial application that everyone has been doing for many years. This will become a situation - send a coin, be an exchange; send another coin, be an exchange; send another coin, this coin has cute dogs on it - these things are fun, but if they are the only ones our industry does, then this industry is a failure. The challenge for our industry is to make an application that is meaningful and that many people like to participate in. In response to the question of why the Ethereum ecosystem and the Web3 ecosystem still do not have practical applications, Vitalik said that before this year, transaction fees were too high, some important technologies were not yet mature, and account security and privacy issues were not solved. Therefore, before this year, our industry did not have enough technology to make applications that ordinary people can participate in. The only reason why the successful application is DeFi is because DeFi can make more money. This year, we finally started to solve these problems. This year is the best time to make meaningful applications.
