Optimism fixes significant testnet vulnerabilities following competitor's alert

🛡 Optimism, a Layer 2 blockchain network, has patched up two ⚠️ critical vulnerabilities in its testnet. These were initially flagged by Offchain Labs, their rival, who discovered potential security threats that could allow attackers to alter the 🔗 chain's history. The issues, reported on March 22, included flaws in the OP Stack fraud-proof mechanism. Optimism addressed the vulnerabilities by updating its testnet on April 25, preventing "subtle attacks" and manipulations.

✔️Despite the rivalry, Offchain Labs acknowledged the complexity of creating secure fraud-proof protocols. Layer 2 testnets serve the vital role of stress-testing the network to uncover such issues before full-scale deployment. Stay alert, stay safe!
