Linea, a zkEVM layer 2 network developed by ConsenSys, has integrated the Phylax Credible Layer into its mainnet. This infrastructure update allows the network to block malicious transactions before they are finalized, shifting from reactive detection to proactive prevention.
The system operates by integrating security technology directly into the Linea sequencer and the broader Linea Stack. Applications can define custom security rules, known as assertions, written in Solidity. These rules act as invariants that must hold true for any transaction to be processed.
When a transaction is submitted, the Credible Layer simulates the outcome. If the transaction violates a pre-defined assertion, the sequencer rejects it before it is included in a block. This approach allows developers to add security layers to existing smart contracts without requiring redeployment.
At launch, four protocols have adopted the system: Euler, Malda, Denaria, and Turtle Club. The feature is opt-in, meaning protection depends on the specific rules configured by each application. Linea expects additional protocols to integrate the technology in the future.
