    How verification works

    Four steps from Stamp ID to decision-time evidence.

    01

    Submit Stamp ID

    Enter a Stamp ID or paste a verification URL

    02

    Query Official Verifier

    Request hits verify.goodproof.mindchill.ai — the only trusted source

    03

    Receive Status + Evidence

    Get the current lifecycle state, scope, expiry, and signer

    04

    Act on Decision Rule

    VALID → proceed. Anything else → block or escalate (fail-closed)

    Fail-closed by default

    Timeout, TLS failure, domain mismatch, malformed response, or any non-VALID status → block or escalate. Never fail-open.

    Try it with demo stamps

    Click any demo stamp to see verification in action.

    Any unrecognized ID returns NOT VERIFIED (fail-closed).
