TechFlow news — Offchain Labs co-founder and chief scientist Ed Felten stated that since the initial mainnet launch in August 2021 featuring built-in security mechanisms, no fraud proofs have been submitted on Arbitrum.
Additionally, Felten noted that Arbitrum is rolling out a new version of fraud proofs called the "BOLD" protocol (Bounded Liquidity Delay). Arbitrum's BOLD protocol was launched by Offchain Labs on August 4. Arbitrum's fraud proof functionality will soon become permissionless, allowing anyone to help ensure chain correctness when challenges arise.
