ZK-Rollup

Definition

A ZK-Rollup is a layer-2 scaling solution for blockchains that bundles numerous transactions off-chain and generates a cryptographic proof of their validity. This proof is then submitted to the main blockchain, allowing for significantly higher transaction throughput and reduced fees. ZK-Rollups use zero-knowledge proofs, which verify the accuracy of computations without revealing the underlying data. Understanding ZK-Rollups is vital for comprehending advancements in blockchain scalability and the efficiency of decentralized applications.
