ZK-Rollup
AdvancedA ZK-Rollup (Zero-Knowledge Rollup) is a layer-2 scaling solution for blockchains like Ethereum. It combines many transactions into a single proof verified on the main chain. Using a zero-knowledge proof, it confirms data without revealing the details of each transaction. This eases congestion on the main chain, lowers costs, and speeds up transactions while maintaining security. ZK-rollups grow more popular as blockchains like Ethereum mature, helping make decentralised applications (dApps) more efficient and affordable for everyday users and developers.
