OP Labs, the core developer of Optimism, released fault proofs on the OP Sepolia testnet before their upcoming implementation on the OP Mainnet.

“Open-source, feature-complete fault proofs are live on OP Sepolia. With permissionless validation, anyone can participate in the system without an allowlist,” the firm stated.

Fault proofs serve as security mechanism for Ethereum Layer 2 networks, enabling users to contest transactions that may be fraudulent or incorrect. They are critical in ensuring that off-chain transaction processing remains free from manipulation.

The OP Mainnet currently lacks fault proofs, a cause for concern regarding the network’s security and decentralization. This means that on the network, users must trust that the block producers submit correct Layer 1 state …
