The problem
Origin and custody claims are asserted by whoever holds the goods, and corrected retrospectively when they are challenged.
01
What is anchored
Custody events, inspections and origin claims.
02
When it is revealed
Anchored at each handover, along the whole chain.
03
Who checks it
Buyers, customs and downstream partners.
The cycle is identical
Canonicalise the artifact, hash it with a secret nonce, anchor the fingerprint, then reveal inside the window. Only the schema and the window change from one application to the next.

The whitepaper specifies the canonicalisation, the hash construction and the contract surface in full.
