Ethereum co-founder Vitalik Buterin explained when rollup-based layer-2 platforms should go decentralized, and why “as soon as possible” is not the correct answer.In a May 5 X post, Buterin said there is a right time for rollup-based scalability solutions to transition to a decentralized model. This moment depends on how low the proof system’s failure probability has fallen compared with the risks introduced by centralization.Buterin’s thread came in response to a separate post by decentralized exchange Loopring founder and CEO Daniel Wang. Wang said in his thread that the maturity of a system matters to its security:“Not all code is created equal. A rollup can be Stage 2, but running fresh code that’s never been tested under real stress.“R...
