ZK Rollup Architecture

Definition

ZK Rollup Architecture is a layer-2 scaling solution for blockchains that aggregates numerous off-chain transactions into a single batch and generates a cryptographic proof of their validity. This proof, a zero-knowledge proof, is then submitted to the main blockchain, significantly reducing the data that the main chain needs to process. This approach vastly increases transaction throughput and lowers fees while inheriting the security guarantees of the underlying layer-1 chain. It represents a powerful method for scaling decentralized applications.
