What Are ZK-Rollups in Blockchain: Complete Scalability Solution Guide

Zero-knowledge rollups, or ZK-rollups, are layer-2 scaling solutions that process blockchain transactions off-chain and submit cryptographic proofs to the main network.[web:33][web:36] Understanding what are zk-rollups in blockchain helps developers and users grasp how modern scaling works. ZK-rollups bundle hundreds of transactions into a one batch, generate a mathematical proof of validity, and settle the final […]
