ZK Proof Aggregation
Frequently Asked Questions
Get specific answers about our ZK cross-chain proof aggregation service, from technical details to project timelines and support.
ZK proof aggregation is a technique that combines multiple zero-knowledge proofs (like zkSNARKs or zkSTARKs) from different blockchains into a single, verifiable proof. You need it to drastically reduce the cost and latency of cross-chain operations. Instead of verifying each proof individually on a destination chain—which is gas-intensive—you verify one aggregated proof. This enables scalable, trust-minimized bridging, messaging, and state synchronization between chains like Ethereum, Polygon, Arbitrum, and zkSync, cutting verification costs by up to 90%.
