According to Odaily, Ethereum co-founder Vitalik Buterin recently addressed community member Daniel Wang's suggestion of naming the L2 network's Stage 2 phase as #BattleTested. Buterin emphasized on the X platform that the second phase is not the sole factor affecting security; the quality of the underlying proof system is equally crucial. He presented a simplified mathematical model to illustrate when to transition to the second phase, considering factors like the independent 'break' chance of each security council member and the likelihood of both operational and security failures.
Buterin explained that the security council's configuration changes from 4/7 in Stage 0 to 6/8 in Stage 1, noting that these assumptions are imperfect. He highlighted the potential for 'common mode failures' among council members, such as collusion or similar hacking methods, which make both Stage 0 and Stage 1 less secure than the model suggests. Therefore, transitioning to Stage 2 earlier than the model indicates is optimal.
Additionally, Buterin pointed out that transforming the proof system into multiple independent systems with multi-signature capabilities can significantly reduce the probability of proof system failure. He suspects that all Stage 2 deployments in the coming years will adopt this approach. He also mentioned the importance of proof system audits and maturity metrics, ideally focusing on proof system implementations rather than the entire rollup, to facilitate reuse.
Buterin concluded by suggesting that @l2beat should ideally showcase these metrics to provide a clearer understanding of the proof system's robustness and maturity.#VitalikButerin #Ethereum #L2Network #Security #BattleTested #ProofSystem #CommonModeFailures #MultiSignature #ProofSystemAudit #MaturityMetrics #L2Beat
🚀 Ethereum Co-Founder Outlines Rollup Security Stages

According to Foresight News, Ethereum co-founder Vitalik Buterin has outlined a three-stage security framework for Ethereum Rollups.
In his recent publication, Buterin described the stages as follows: Stage 0 involves a security council with the authority to completely override the proof system, resulting in centralized control. Stage 1 requires the agreement of six out of eight members to intervene, with external member thresholds limiting intervention. Stage 2 allows intervention only in the event of verifiable errors, without arbitrary decision-making.
Buterin recommends a gradual transition from Stage 0 to Stage 2 as trust in the proof system increases. He emphasizes that Stage 0 offers the lowest security and should not be maintained for extended periods. Rollups should ideally start at Stage 1, with a focus on auditing and enhancing the maturity of the proof system.#Ethereum #VitalikButerin #RollupSecurity #Blockchain #Web3 #Decentralization #ProofSystem
