Optimism disabled unauthorized fraud proofs as a precautionary measure proposed by a protocol engineer. The proposal outlines the Granite network upgrade, which responds to vulnerabilities identified by third-party auditors. If the upgrade passes, it will provide better security and performance to OP Mainnet’s fault-tolerant system.
What Is Happening on the Optimism Front?
Disabling unauthorized fraud proofs and opting for authorized ones came after audits revealed several errors in the recently launched system. The report indicates that the audit uncovered two high-priority issues, prompting the network to take extra precautions. Importantly, the Optimism team assured users that their assets remain secure. Mofi Taiwo, a protocol engineer representing OP Labs, shared the following statement:
“Had an attack been detected, the Auxiliary Guardian role held by the Optimism Foundation and revocable by the Security Council would have been expected to blacklist any vulnerable dispute game or enable authorized rollback.”
In a May upgrade proposal, the Optimism network committed to enhancing its core security mechanisms. It also promised to gradually build trust in the system’s reliability over time. This commitment led to the decision to enable authorized rollback and restrict output proposals, providing tighter control over potential vulnerabilities.
The recent audit categorized the vulnerabilities as threats to OP Mainnet‘s reputation and vitality. According to the project’s guidelines, these did not require formal audits and thus fell outside the scope of Optimism’s audit. Nonetheless, they were flagged due to their relevance to the network’s fraud-resistant system contracts.
Details on the Matter
OP Labs does not foresee any disruptions due to the Granite Network Upgrade. However, if the hard fork proposal passes, node operators must update their software by September 11, before the deadline. Since unauthorized fraud proofs are now disabled, all pending withdrawals are invalidated. Withdrawals initiated less than a week before the upgrade will only be finalized a week later.
The development reflects ongoing fundamental security concerns affecting the DeFi space. Optimism’s native token OP fell by 0.3%, paralleling broader market gloom. However, the Layer-2 network’s Total Value Locked (TVL) has increased by $5.88 million since the upgrade announcement. OP Labs does not foresee any disruptions due to the Granite Network Upgrade.
