Shared Security Model

Architecture

A shared security model describes an architectural approach where multiple independent networks or applications derive their security from a single, larger, and more robust underlying blockchain. This design pattern, often implemented by Layer 2 solutions, leverages the base chain’s consensus mechanism to secure its own state transitions. By submitting proofs to the main chain, Layer 2 networks benefit from the high-cost-to-attack threshold of the parent network without performing all computations directly on it.
