The real danger in resale title is not price swings but the same cargo pledged twice. With many intermediaries and fast transfers, a paper bill plus email confirmation can break at any hand; a bank that cannot see the full picture advances funds and the risk is buried.

Chained attestation works like this: each time title moves, a hash is generated that bundles the previous hand's hash, the timestamp, vessel and voyage, and the transferee, then a new SHA-256 hash is appended to the chain tail. The whole chain is tamper-evident like a fingerprint; alter any hand and every later hash fails to match.

Before lending, the bank no longer looks only at the final bill but pulls the entire chain: who loaded, how many intermediate hands, whether each transferee and timestamp line up. Only when the ownership chain is intact and carries no double-pledge flag does the money move. This stops one cargo, many sales before funding, not after the fact.

For a resale structure hung on an offshore SPV, chained attestation also settles the cross-bank due-diligence problem; who touched it, in whose name the cargo sits, and which hand the cash should follow are visible on the chain, sparing a fresh KYC run every time.
