• Users are granted the ability to challenge and invalidate any incorrect withdrawal attempt initiated by the team's sequencer.
• The development team at OP Labs reports that Optimism, Ethereum's layer-2 solution, has incorporated fault proofs into its smart contracts, marking the transition to what Vitalik Buterin, the co-founder of Ethereum, calls 'Stage 1' of decentralization.

As per the team's announcement, the OP Stack networks – Base, Metal, Mode, and Zora – are preparing to integrate the fault proofs shortly. Users of Optimism can now independently request withdrawals of ERC-20 tokens and Ether (ETH) without the dependence on trusted third parties. Furthermore, users retain the right to challenge and dismiss any fraudulent withdrawal attempt made by the team's sequencer by presenting evidence of its inaccuracy.

Progressing Towards Full Decentralization

The recent development empowers the Optimism Security Council to supersede the fault proofs with a six-of-eight majority. This new protocol, as explained in the announcement, does not entirely eliminate the sequencer's authority to halt legitimate withdrawals or process incorrect ones. However, with this transition, users are now responsible for verifying withdrawals, and any modifications to this process must be approved through a council vote.

Transitioning to 'Stage 1' is a crucial step towards achieving full decentralization, with future aspirations for 'Stage 2.' The roadmap includes scenarios where the Security Council can only bypass the fault proofs in case of conflicting outcomes from diverse proving systems.

The team envisions a future where Optimism incorporates multiple fault-proof systems beyond just Cannon, aiming to achieve a state of 'multi-proof nirvana.' This state will entail the sequencer confirming only legitimate transactions using a variety of evidence mechanisms.
