Independent verification
Verify a record.
Trust no one.
The open-source verifier recomputes every hash, signature, chain link, Merkle root, and witness cosignature from scratch, trusting neither the agent that produced the record nor the sink that stored it.
Runs entirely in your browser. Your bundle never leaves your device, not even to us.

The exact same verifier runs offline in the
pr verify CLI and is tested against a
frozen public conformance-vector suite, in both Python and JavaScript. Want to record your own
