Optimism Foundation disables permissionless fraud proofs
#OptimismFoundation has temporarily disabled its permissionless fraud proofs, a system designed to let all users contest transactions on its
#layer2 network. This decision follows security audits that uncovered several bugs, including two high-severity issues. The network will revert to a permissioned state as a precaution.
The Foundation plans a hard fork, named
#Granite , scheduled for September 10, to address these vulnerabilities.
