The weak point of a traditional warehouse receipt is not whether a record exists, but whether it can be verified independently. SNSUC moves that step into the browser: the title certificate computes a 256-bit SHA-256 hash client-side, and the fingerprint ships with the certificate so the buyer recomputes it and accepts only a match.

Title and ESG carbon footprint ride the same hash chain. At issuance, each receipt carries structured fields — load port, transport mode, emission factor — which are hashed and anchored on-chain. A buyer in due diligence no longer chases emails or calls the warehouse; one hash comparison confirms both origin and carbon load.

For transshipment, this turns "clear title" from a promise into a verifiable mathematical fact. Before presenting documents under a letter of credit, both the bank and the trader check the same hash key, cutting the back-and-forth cost of verification.
