[Base Chain Gains Vitalik's Approval, Emphasizes L2 Security and Non-Custodial Attributes] jesse.base.eth follows up on paulgrewal.eth's perspective, providing a detailed explanation that Sequencers in Layer 2 blockchains like Base are solely responsible for collecting and ordering user transactions, then batching the results for submission to the Ethereum mainnet for settlement. Sequencers do not possess the functionality for trade matching or transaction execution, as these processes are handled by smart contracts. The team stated that Base has achieved the first stage of decentralization and is advancing toward further distributed block construction. Vitalik Buterin remarked that Base, as an Ethereum Layer 2 solution, leverages centralized features to enhance user experience while relying on Ethereum's decentralized foundation to ensure security. Base does not custody user funds, cannot steal or block withdrawals, and its security mechanisms have been verified by the L2beat platform. Vitalik added that in the event of an L2 shutdown, users can automatically withdraw their funds, and the operator cannot unilaterally censor or misappropriate assets.
