Independent verification · no login

Verify a signed AxiomSeal audit report.

Drop the report your counterpart handed you. This page checks the Ed25519 signature and rebuilds the SHA-512 seal chain from the memory content itself — so you can confirm the record without taking AxiomSeal's word for anything.

How this verifier works

Signature. The report is re-serialised into its canonical form — key-sorted, no whitespace, its own signature field removed — and the Ed25519 signature is checked over exactly those bytes with the public key published at /.well-known/axiomseal-audit-key.json.
Seal chain. Each memory is re-hashed as sha512(canonical_body + ":" + prev_sigma) and compared against the seal stored in the report. The first mismatch is reported by seal number — everything after it is unproven.
No network trust. Only the public key is fetched. Your report is read locally and never transmitted.
