ZK Rollups are a layer 2 scaling solution that uses validity proofs to scale computation: each batch of transactions comes with a cryptographic proof (ZK-SNARK) that is verified by an Ethereum smart contract. This way every single transaction is fully verified by all Ethereum full nodes before a block is finalized.
