Verify Proof Bundle

Paste any ProofPack JSON and verify it offline. No account required.

All verification runs in your browser. Nothing is sent to any server. The verifier checks the artifact. It does not decide whether a claim is true — only whether the evidence, event chain, and acceptance are intact.

This verifier implements the ProofPack v2 5-step offline verification algorithm: bundle hash (SHA-256), event chain integrity, RFC 6962 Merkle inclusion, Ed25519 STH signature, and cross-reference check. Source algorithms are published in the conformance vectors.
