At the request of the Ethereum Foundation, the technology security company Least Authority has completed its review of the ETH 2.0 specification. Based on the final audit report, Least Authority considers these norms to be “well thought out and comprehensive.” However, the team believes that there are no real examples of using PoS and sharding expansion protocols. In this sense, it is currently difficult to assess the long-term stability of ETH 2.0. In addition, the report identified two potential security risks: the block proposal system and the P2P messaging system. The report states that both require long-term research and may be addressed in later stages of the project.
