The development of Ethereum 2.0, the upgraded protocol that Ethereum will be shifting onto was found to have vulnerabilities with the peer-to-peer (p2p) networking layer and the block proposer system after a security audit.
Security firm Least Authority carried out the security audit at the request of the Ethereum Foundation, and claim in the audit report, ‘specs to be very well thought out and comprehensive.’
Untested PoS Could Create Problems
However, the auditing team said that because there hadn’t been any real-world example of a large-scale proof-of-stake (PoS) protocol, it would be difficult to assess the success of ETH 2.0 and its long term stability.
‘It is one of the first Proof of Stake/sharded protocol projects planned for production,’ the report said. ‘As a result, there has been minimal opportunity to study the impacts of design decisions on real-world uses of such blockchain implementations, and none at the same scale. The long term stability of PoS blockchains is an area of active research that will need to be monitored over time as they are used in production.’ Read More..
