Key Takeaways
- As audits discovered vulnerabilities, optimism returned to permitted fraud proofs.
- A tough fork referred to as “Granite” is scheduled for September tenth to replace the Optimism community.

Optimism has reverted the community to permissioned standing after a community-led audit uncovered a number of bugs, together with two high-severity points, in its not too long ago deployed permissionless fraud prevention system.
The Optimism Basis introduced the rollback of X, saying it took the step “out of an abundance of warning” to keep away from potential instability till the vulnerabilities have been fastened.
In March, Optimism started testing a fault prevention system on Ethereum’s Sepolia take a look at community to strengthen safety and decentralization and handle criticism over earlier vulnerabilities.
The choice comes simply two months after the community carried out permissionless fraud proofs on June 10 and the following token unlocking occasion, which strengthened the community and enabled the withdrawal of Ethereum and ERC-20 tokens, marking a milestone in reaching Stage 1 decentralization as outlined by Ethereum co-founder Vitalik Buterin.
Mofi Taiwo, a protocol engineer representing OP Labs, an Optimism contributor, mentioned: Submitted a proposal The community’s governance discussion board detailed its causes for activating the fallback system, stressing in a publish that the vulnerability had by no means been exploited within the wild and that no customers’ belongings have been ever put in danger.
“Whereas the auditors discovered a number of excessive severity points, no consumer belongings have been put in danger. All the audit points listed beneath have been detectable by our monitoring instruments,” Taiwo mentioned within the proposal.
The recognized vulnerabilities primarily have an effect on contracts associated to anti-fraud techniques which can be outdoors the scope of Optimism’s audit. These contracts have been categorized as posing existential and reputational dangers that don’t require a proper audit, in keeping with the undertaking’s tips.
To deal with this problem, Taiwo has proposed an improve referred to as “Granite”, scheduled for September tenth at 16:00:01 UTC. The improve will embrace a number of updates to the community, together with an L2 laborious fork. Whereas the laborious fork has not been formally audited, OP Labs carried out an inner safety overview and decided that the danger of the change is low.
