Optimism (CRYPTO:OP), an Ethereum (CRYPTO:ETH) layer-2 network, has achieved “Stage 1” decentralization by integrating fault proofs into its smart contracts, according to OP Labs.

This milestone allows users to independently initiate withdrawals without third-party involvement.

The new system enables any user to challenge and remove invalid withdrawals, shifting default validation to the users.

This progress towards full decentralisation includes plans for multiple fault-proof systems and further security measures.

Optimism founder Karl Floersch emphasized the significant strides being made towards decentralisation despite the complexity involved.
