Ethereum co-founder Vitalik Buterin told The Block that the multi-client Ethereum 2.0 testnet may be released in April. He said, “The best way to think about when to start the Ethereum 2.0 Phase 0 mainnet is to first require a multi-client testnet, and then wait for the testnet to run for a period of time before starting, which is in line with our ETH 1.0 process in 2015. It ’s similar. So it ’s difficult to predict when the mainnet will be launched, although we expect the multi-client testnet to go live as soon as possible, April seems to be very likely. ”Previously reported by the chain, the technology security company Least Authority has completed the ETH 2.0 specification. Review. According to the final audit report, Least Authority believes that these specifications are “thoughtful and comprehensive”, but there are two potential security risks, and it is difficult to assess the long-term stability of ETH 2.0. These two potential security risks are: the block proposal system and P2P messaging system. The report states that both require long-term research and may be addressed in later stages of the project.
