Consensus Security Inheritance

Definition

Consensus Security Inheritance describes how a layer-2 blockchain or application derives its security properties from the underlying layer-1 network’s consensus mechanism. The layer-2 system relies on the robust, decentralized validation of the base chain to secure its own transactions and state. This relationship means the layer-2’s integrity is directly tied to the cryptographic and economic security of the layer-1. It allows layer-2s to scale while leveraging the battle-tested security of a more established blockchain.
