The team has implemented fault proofs on Optimism mainnet, and users can now independently initiate withdrawals “without involvement from any trusted third parties.”
Ethereum layer-2 Optimism has implemented fault proofs into its smart contracts, according to its development team, OP Labs. According to the team, Optimism has now reached “Stage 1” of decentralization, referring to a list of milestones articulated by Ethereum co-founder Vitalik Buterin.
At least four other OP Stack networks will implement the fault proofs “soon,” including Base, Metal, Mode, and Zora.
On Optimism, users can now initiate withdrawals of Ether (ETH) and ERC-20 tokens “without involvement from any trusted third parties,” OP Labs said in a post. In addition, if the team’s sequencer attempts to process invalid withdrawals, they can be “challenged and removed” by any user who submits a fault-proof showing that the withdrawal is invalid.
