Title holders hash the bill of lading, inspection and delivery note locally with SHA-256 before going on-chain; the ESG carbon ledger is traced per leg while holders keep their source documents.

SNSUC digital receipts hash client-side with SHA-256 and sign on-chain, cutting title transfer from three days to ten minutes while ESG footprints are fixed as verifiable records.

Bills of lading, inspection and title are hashed in the browser to a 256-bit digest; title transfer compares hashes only, and the carbon footprint rides the receipt for one-click compliance pulls.
