According to Odaily Planet Daily, at the ETHBerlin event last week, Ethereum co-founder Vitalik Buterin described some of his regrets about the initial design of Ethereum. Vitalik said that there are a series of things he could have done differently, including the development of the Ethereum virtual machine, smart contracts, and the PoS consensus mechanism. He also said that even though Ethereum is becoming more and more mainstream, it is still misunderstood. Vitalik said that Ethereum's original EVM design chose 256-bit processing instead of 64 or 32 bits. The original design was too complicated for 256 bits, which is very inefficient and can generate a lot of redundant data on the blockchain even when performing simple tasks.
Vitalik said that Ethereum's switch from the PoW consensus mechanism to the PoS mechanism in 2022 should have been done earlier. He also mentioned: "The automatic log of Ethereum transfers should have existed from the beginning, and it only took us 30 minutes to code it, but it became an EIP." EIP-7708, submitted by Vitalik on May 17, will make this precise change. Vitalik said that if he chose again, he would use SHA-2 to encrypt Ethereum instead of the Keccak encryption algorithm currently used. Despite a series of small design mistakes, Vitalik said that any project is bound to encounter such a situation. He said: "I am really happy that I feel that our core developers and their execution capabilities seem to be improving every year. We now have the ability to effectively and safely correct some of these mistakes."
