Optimism Enhances Security by Disabling Unauthorized Fraud Proofs
Optimism has taken a significant step to bolster its security by disabling unauthorized fraud proofs, following a precautionary measure proposed by a protocol engineer. This decision is part of the Granite network upgrade, a response to vulnerabilities identified by third-party auditors. If the upgrade is approved, it will strengthen the security and performance of OP Mainnet’s fault-tolerant system.
What Is Happening on the Optimism Front?
The decision to disable unauthorized fraud proofs and shift to authorized ones came after audits exposed several flaws in the recently launched system. The audit report highlighted two high-priority issues, prompting the network to implement extra security measures. Despite these concerns, the Optimism team reassured users that their assets remain safe.
Mofi Taiwo, a protocol engineer representing OP Labs, issued 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 reinforcing its core security mechanisms. The network also pledged 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, offering tighter control over potential vulnerabilities.
Impact of the Granite Network Upgrade
The recent audit categorized the vulnerabilities as threats to OP Mainnet’s reputation and vitality. Although these issues did not require formal audits according to the project’s guidelines, they were flagged due to their significance to the network’s fraud-resistant system contracts.
OP Labs does not anticipate 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.
- Unauthorized fraud proofs are now disabled.
- All pending withdrawals are invalidated.
- Withdrawals initiated less than a week before the upgrade will be finalized a week later.
Broader Implications for the DeFi Space
This development highlights ongoing fundamental security concerns affecting the DeFi space. Despite a 0.3% drop in Optimism’s native token OP, reflecting broader market conditions, the Layer-2 network’s Total Value Locked (TVL) has increased by $5.88 million since the upgrade announcement.
OP Labs remains confident that there will be no disruptions due to the Granite Network Upgrade. However, node operators are urged to update their software before the September 11 deadline to ensure continued smooth operation.
