Economic Fraud Proofs

Mechanism

Economic fraud proofs are a core component of optimistic rollups, where transactions are assumed valid by default, but a challenge period allows participants to submit a proof of fraud if they detect an invalid state transition. This mechanism relies on economic incentives to ensure honest behavior, requiring sequencers or validators to stake collateral that can be slashed if fraud is proven. The proof itself is a cryptographic verification that demonstrates a discrepancy between the proposed state and the actual outcome of the transactions.
