Frequently Asked Questions
Get clear answers on our development process, security, and timelines for custom ZK Proof Storage Verifier solutions.
A ZK Proof Storage Verifier is a smart contract or off-chain service that cryptographically verifies the integrity and authenticity of data stored off-chain (like IPFS, Arweave, or cloud storage) using Zero-Knowledge Proofs. You need one to build scalable, trust-minimized applications where data availability is separate from consensus, such as layer-2 solutions, verifiable data markets, or privacy-preserving dApps. It ensures users can trust that the data referenced on-chain is correct without having to store the full data on-chain, drastically reducing gas costs.
