Ethereum co-founder Vitalik Buterin has discussed the appropriate timing for rollup-based layer-2 platforms to transition to decentralization, stressing that it is not ideal to do so 'as soon as possible'. In a recent post, Buterin stated that the shift should occur when the proof system's failure probability is significantly lower than the risks posed by centralization. His commentary follows remarks from Loopring founder Daniel Wang, who highlighted the importance of code maturity for security. Rollup development is categorized into stages, with stage two representing full decentralization. Wang proposed a 'BattleTested' badge for rollups that securely managed substantial assets over time, underscoring the need for rigorous security standards. Buterin concurred that the underlying proof system's quality is crucial for security. An analyst noted that rollup teams should ensure sufficient security before moving from stage one to stage two. Ultimately, Buterin advised that decentralization should be pursued only when the proof systems are robust enough to mitigate the risks introduced by centralized control.
