Optimistic Proofs

Definition

‘Optimistic Proofs’ are a cryptographic technique used in zero-knowledge rollups to verify the validity of transactions on a blockchain. They operate under the assumption that all submitted transactions are valid by default, and only challenge invalid transactions during a specific dispute period. If a transaction is proven to be fraudulent, a penalty is applied, and the incorrect state is reverted. This approach allows for significantly higher transaction throughput compared to traditional on-chain verification methods.
