Layer 2 network Optimism has successfully addressed two critical vulnerabilities on its testnet that could have allowed malicious actors to manipulate chain history and execute attacks.

The vulnerabilities were first discovered by Offchain Labs in March, enabling attackers to trick the OP Stack fraud-proof mechanism into accepting fraudulent chain histories.

In collaboration with Offchain Labs, The Arbitrum Foundation has announced the launch of the Arbitrum Expansion Program and the Arbitrum Developer Guild.

This program allows teams to create custom Arbitrum Orbit Chains, allowing them to deploy their own version of the Arbitrum technology stack.

Offchain Labs announced in its 2023 review that Arbitrum Stylus, a new tool that supports multiple languages for smart contracts, is live on the testnet and will launch in 2024.

Arbitrum DAO also plans to deploy Stylus to Arbitrum One and Nova, as well as use Stylus on the Orbit chain.

**🔧Offchain Labs Update**: Offchain Labs, the creator of Arbitrum (ARB), identifies network failure on the 15th due to high traffic concentration causing transaction delays and fee spikes. Normal functionality is restored through a new Arbitrum One version distribution. 💼🌐 #OffchainLabs #ArbitrumUpdate
