SNSUC computes a SHA-256 fingerprint of warehouse-receipt fields directly in the browser and anchors it on a blockchain, so title transfer and claim happen at once. The same hash also carries ESG carbon-footprint data, giving every transshipped batch a traceable carbon ledger from load port to delivery.

SNSUC generates a SHA-256 fingerprint of warehouse-receipt elements directly in the browser, binding title and timestamp without a central server. The same chain extends downstream to ESG carbon-footprint accounting, with emission factors attached per grade across the 13 categories.
