Vitalik Buterin Explains the Importance of Proof Systems for Ethereum’s L2 Network Stage 2 Transition

On May 5th, COINOTAG News reported on a significant discussion within the Ethereum community regarding security protocols for Layer 2 (L2) networks. Responding to Daniel Wang’s proposed hashtag #BattleTested, Ethereum co-founder Vitalik Buterin emphasized that the security of these networks hinges not only on its stages but also on the robustness of the underlying proof system. In his post on Platform X, Buterin elaborated on a mathematical model that assesses risks associated with transitioning to Stage 2. He pointed out that the assumptions underlying this model are imperfect, highlighting potential vulnerabilities such as collusion among security council members. Moreover, he advocated for a shift towards a multisignature proof system, which could significantly reduce the risks of proof system collapses. The conversation underscores the necessity for enhanced auditing and maturity metrics in the L2 ecosystem to mitigate protocol collapse.
