Vitalik: Both Optimism and Arbitrum meet the voting threshold requirements of the security council and cannot unilaterally steal funds

ChainCatcher message, Ethereum co-founder Vitalik Buterin responded on the X platform to "currently all major L2 networks in the mainnet can technically steal user funds," stating an important detail: the rules of Phase 1 require that code can only be overturned when the security council reaches a voting threshold of 75%, and the members preventing a quorum (i.e., ≥ 26%) must come from outside the company. Both Optimism and Arbitrum meet this requirement. Therefore, these organizations cannot unilaterally steal funds.
