A digital warehouse receipt is not a scanned document filed away. At SNSUC it is a SHA-256 digest computed in the browser for each receipt, then anchored on-chain together with title, inspection and logistics records. A 256-bit hash means changing a single byte anywhere flips the whole digest, so the receiver sees tampering instantly.

SNSUC treats the ESG carbon-footprint field as mandatory on every receipt, matching the due-diligence format international buyers expect. Title transfer runs in three steps — title registration, inspection review, on-chain notarisation — and only a complete set closes the transfer. All 13 core categories at SNSUC are on this flow; no grade is exempt.

For an operator the value is trust cost. Paper receipts need stamps from warehouse, supervisor and bank. After anchoring, a buyer verifies one hash, and dispute evidence that once took weeks now takes minutes.
