A prominent example is zero-knowledge proving mechanisms that operate off-chain, such as a zk-SNARK or zk-STARK. These protocols prove that the transactions in a batch satisfy the rules of the protocol. These proofs are submitted to the L1 chain and verified without needing further interaction. An interactive method involves a back-and-forth process between parties to validate transactions. A -prominent example is fraud proofs, as used in optimistic rollups. If a dispute arises, a challenge +prominent example is the usage of fraud proofs, as used in optimistic rollups. If a dispute arises, a challenge mechanism is triggered, where a "prover" submits evidence (fraud proof) to demonstrate that a transaction is invalid. This can require multiple steps, with both the challenger and defender submitting data to the L1 chain.
