Optimism has announced the launch of its **liveness module**, a technical solution designed to improve network reliability and uptime. The module addresses critical infrastructure challenges in the Optimism network, though specific technical details are available in their [full blog post](https://www.optimism.io/blog/liveness-module). This development continues Optimism's focus on building robust scaling solutions for Ethereum. The team is actively [hiring](http://optimism.io/careers) engineers interested in solving similar technical problems. Developers can explore building on Optimism's infrastructure at [optimism.io](https://www.optimism.io/).

A critical security primitive has been released as open-source, removing proprietary barriers in the industry. **Key Points:** - The tool is now freely available for anyone to use, fork, or improve - Developers believe making security tools publicly accessible strengthens the entire industry - The release follows a philosophy of transparency over "security by obscurity" The move represents a shift toward collaborative security development, allowing the community to build upon and enhance the tool rather than keeping it behind closed doors.

Optimism has deployed a new open-source module for multisig operations, following a security audit by Spearbit. **Key Details:** - The module is now publicly available and open-source - Successfully audited by Spearbit security firm - Already in production use by Optimism's own multisig wallets - Built to address internal operational needs The team developed this tool to solve their own requirements before releasing it to the broader ecosystem. The module represents Optimism's continued investment in infrastructure tooling for Layer 2 operations.

A new liveness module addresses a critical security gap in multisig wallets. The system works through a simple challenge-response mechanism: - A trusted fallback can challenge the multisig with "Are you still alive?" - The multisig must respond by executing a transaction - If too many keys are lost or compromised, the fallback takes control **Key Innovation:** The module cleverly handles malicious actors who block legitimate transactions while signing liveness proofs to appear active. The solution: honest signers simply don't respond to challenges, triggering the fallback mechanism automatically. This prevents scenarios where bad actors maintain control by appearing operational while blocking real transactions.
