Fraud Proofs

Fraud proofs are a security mechanism used in optimistic rollups to detect and challenge invalid state transitions. If an operator submits an incorrect state update to the base layer, a watcher can submit a fraud proof that demonstrates the error using the transaction data.

The base layer then verifies this proof and, if valid, reverts the incorrect state and penalizes the sequencer. This system relies on the assumption that at least one honest participant is watching the chain to detect fraud.

It is a fundamental component of optimistic scaling solutions, allowing for high throughput while maintaining security. The design of fraud proofs requires careful consideration of the virtual machine logic and the ability to reproduce the execution state accurately.

By providing a pathway for correction, they ensure that the system remains honest even in a decentralized, permissionless environment.
