A Zero-Knowledge (ZK) Rollup is a Layer 2 blockchain scaling solution that bundles transactions offchain and uses cryptographic proofs to verify them efficiently on-chain. By validating transaction data without revealing its contents, ZK Rollups maintain privacy while reducing congestion on Layer 1 networks like Ethereum.

Examples of ZK Rollups are zkSync and Starknet.
