Base to Launch Fault Proofs This Month to Enhance Decentralization

Base, the Ethereum Layer 2 platform incubated by Coinbase, is set to implement permissionless fault proofs on October 30, marking a significant step toward decentralizing the network and reducing single-entity control.
"Fault proofs are coming to Base mainnet on October 30th, marking a key milestone on the path to decentralization," the platform announced.
Since its launch in August 2023, Base has quickly grown to become the largest Layer 2 rollup on Ethereum by total value locked, developed using Optimism’s OP Stack package.
The upcoming implementation of fault proofs will follow a similar model to that already in place on Optimism’s flagship blockchain, OP Mainnet. Both Base and Optimism are part of the Superchain ecosystem, which includes projects like Zora, Mode, and Fraxtal.
Base has collaborated closely with Optimism to enable this upgrade. Fault proofs will allow users to challenge potentially fraudulent or incorrect transactions on the network, enhancing overall security. Prior to this upgrade, only a centralized proposer could submit state output roots for the Base network, which meant users had to trust operators to accurately report state roots to the mainnet.
With the introduction of fault proofs, any participant will be able to claim the current state of Base and contest invalid withdrawals, thereby strengthening the network’s integrity.
While many optimistic rollup blockchains have not yet incorporated fault proofs or decentralized contract upgrades, notable exceptions include Arbitrum and OP Mainnet, which have already implemented these features.
