Zero-Knowledge Rollups Technology

Architecture

Zero-Knowledge Rollups (ZK-Rollups) represent a Layer-2 scaling solution for blockchains, fundamentally altering transaction processing. They bundle numerous transactions off-chain into a single batch, significantly reducing the load on the main chain. This architecture relies on cryptographic proofs, specifically succinct non-interactive arguments of knowledge (SNARKs) or succinct non-interactive arguments of knowledge with zero-reduction (zk-SNARKs/zk-STARKs), to validate the batch’s integrity. Consequently, only the proof needs to be posted on-chain, drastically improving throughput and lowering transaction costs while maintaining security.
