Security

Lineth (formerly the Linea Stack), together with operator-controlled integrations, offers certain security capabilities. These capabilities are provided through both protocol-level guarantees and operator-controlled integrations.

Define security capabilities​

Lineth provides protocol-level guarantees, while operators implement operational controls.

Protocol-level guarantees​

The protocol offers certain security guarantees:

  • Cryptographic correctness guarantees via zk-SNARKs
  • Byzantine fault tolerant consensus (QBFT)
  • Finalization security inherited from the finalization layer
  • Protocol-level security invariants

Operational security integrations​

Operators retain full control over their secure boundaries:

  • Infrastructure isolation and network security controls
  • Role-based access control (RBAC) for APIs and services
  • Secure key management via KMS-backed signing and remote signing through Web3Signer
  • Monitoring and incident response tooling
