Vitalik Buterin: Some L2 projects are not fully decentralized
ME News, May 16 (UTC+8). On July 3, 2025, Ethereum co-founder Vitalik Buterin said in his EthCC speech that many Layer 2 projects claiming to be built on-chain have backdoors that can be triggered at any time or lack sufficient decentralization. He believes that the architecture of these projects is hardly any different from traditional centralized servers. He pointed out that if developers cannot ensure the project is thoroughly decentralized, directly using centralized servers may be more practical. (Source: MLion)
