OP Labs has released bug proofs on the Layer 2 OP Mainnet blockchain — bringing the project to phase 1 rollup in terms of decentralization.

The proof-of-fault system allows withdrawals of ETH and ERC-20 tokens from the OP Mainnet without the need for trusted third parties – allowing users to challenge and eliminate invalid withdrawals. Fault proof acts as a mechanism for Ethereum's Layer 2 networks, allowing users to dispute potentially fraudulent or erroneous transactions.

Before being approved through Optimism's governance structures, the proof-of-fault implementation was supported by multiple core development teams within the Optimism (or Superchain) ecosystem, including OP Labs, Base and Sunnyside Labs — shows a collaborative effort.

Previously, OP Mainnet had no proof-of-fault – requiring users to trust operators to send correct state roots to mainnet.

OP Mainnet and other Optimism ecosystem chains use optimistic rollups as a scaling solution, aggregating off-chain Ethereum transactions for cheaper processing.

OP Labs — the developer of OP Mainnet — also operates a development software stack called OP Stack, which allows developers to launch their own Layer 2 blockchains. Cryptocurrency exchange giant Coinbase developed its blockchain, called Base, using the OP Stack.

While proof-of-bug is now live on OP Mainnet, other OP Stack chains will upgrade to include this feature, starting with Base, Metal, Mode, and Zora.

Oversight role of the Security Council

Although open participation in the bug proof system is active, the Optimism Security Council can still intervene and roll back the system to a permissive state in the event of a system failure as part of the implementation process. Declare safely and responsibly. Additional protections allow the Security Council to effectively handle system failures, including the ability to reset withdrawals if necessary.

OP Mainnet has a roadmap towards a completely permissionless and decentralized phase 2, managed entirely through smart contracts.

Most optimistic blockchain rollups have yet to decentralize their networks using a combination of proof-of-fault and maintaining decentralized contract upgrades. However, Optimism's closest competitor, Arbitrum, also offers bug proofing.
