Certificate of Origin
The most-signed document in global trade, rebuilt as code.
The Certificate of Origin is the document customs, buyers, and retailers all fall back to. Volum issues each certificate as a signed cryptographic record, linked to its custody events, verifiable by any downstream party without a phone call.

Volum Registry Node 04
The redesign
What the paper certificate cannot do.
01 - verify
Independent verification.
A downstream buyer verifies the certificate against the Volum registry without contacting the issuer.
02 - link
Linked custody trail.
The certificate is anchored to the underlying custody events. Provenance is auditable end-to-end.
03 - revoke
Revocation and correction.
Errors and revocations propagate to every verifier in seconds via the on-chain status list.
