Offchain Labs team disclosed two serious security vulnerabilities in Optimism to OP Labs, occurred on March 22. The vulnerabilities were found in Optimism fraud proof system deployed on the testnet. OP wiped out nearly 2% of its value in the past day. The tweet explains that these were identified in Optimism ’s fraud proof system deployed on the testnet.
The OP Stack could have faced an attack from a malicious party and this could force the Stack to accept a fraudulent chain history. This could prevent Optimism from accepting a correct chain history. Today, we disclosed two serious vulnerabilities in the recently released OP Stack fraud proofs. We coordinated closely with the OP Labs team on this disclosure. We’re all on team Ethereum, and happy to lend resources to make Ethereum safer for everyone.https://t.
