Fraud Proof System Design

Architecture

Fraud proof system design operates as a specialized security framework within layer-two blockchain scaling solutions, specifically engineered to ensure the integrity of off-chain transaction states. It relies on a challenge-response mechanism where participants, known as watchers, monitor state roots for inconsistencies against the canonical chain. This structure necessitates a permissionless environment where any party can submit a cryptographic proof to invalidate fraudulent state transitions, thereby reverting the system to a known secure configuration.
