Base has achieved the first phase of Ethereum Rollup Decentralization, launching a fault-proof mechanism and establishing a security committee.

On April 30, Base reached the "first phase" of Ethereum Rollup decentralization, launched a proof-of-fault mechanism and established a security committee. According to Base developers, the network has reached the "first phase" of Vitalik Buterin's Rollup decentralized framework, making progress in reducing its reliance on centralized actors. "Base has achieved the first phase of decentralization, which is a key milestone in the process of building an open global on-chain economy. This was achieved through the introduction of permissionless proof of failures and the decentralization of the contract escalation process through the Security Committee." Launched in August 2023 using Optimism's OP Stack package, Base has grown to become the largest Layer 2 rollup for TVL on Ethereum. Previously, Base was classified as a Phase 0 Rollup, mainly because it still relied on CEX-controlled centralized sequencers and its mainnet lacked fully operational proofs of permissionless failures.
