A digital warehouse receipt is worth more than custody proof. Once a receipt is hashed on-chain with SHA-256 and its title and status are verifiable, it acquires a financial-asset character - it can be pooled, split and discounted much like a receivable.

Concretely: a trader injects in-transit crude or rubber receipts (say 5kt of natural rubber, roughly 95 million yuan of value) into a special-purpose vehicle, and the future delivery right plus the repayment cash flow become the underlying asset of a 6-12 month supply-chain ABS. Investors buy the certainty that the goods exist, title is clean, and they can be liquidated - not a price bet.

On the bank side the key is not the collateral face value but the on-chain status: is the goods in storage, in transit or already lifted? Has the title been pledged twice? SHA-256 pins every transfer, blocking duplicate financing at the technical layer first. Lending moves from the 3-5 day letter-of-credit negotiation to T+0 discounting, at a funding cost roughly 150 basis points below traditional negotiation.

For SNSUC the point is to activate smaller traders: we hold the real title and provenance data, so acting as the ABS asset servicer is lighter and steadier than simply advancing capital. The risk line is unambiguous - a one-vote veto on origin (Iran) sits in onboarding, and any abnormal title status pauses pooling. Scale never justifies relaxing it.
