Paper bills move by courier and endorsement; a single title transfer often takes days. Under the Model Law on Electronic Transferable Records and the MLETR framework, electronic bills of lading gain the same legal standing as paper, lifting title from a physical document onto a verifiable data object.

The mechanics: hash the bill's key fields — number, vessel, voyage, load port, quantity — with SHA-256 and record the digest on-chain. Any party can verify at any time whether the bill has been altered and who currently holds title. Steps that once needed mailing, checking and endorsement become minute-level state changes on the chain.

On settlement, electronic bills replace roughly a quarter of letter-of-credit document examination. The bottleneck in an LC is rarely funding; it is the examination, where a discrepancy can stall the whole transaction. With the bill on-chain, checking shifts from matching paper by hand to matching hashes by system, pushing discrepancies to the issuance stage.

Banks demand enhanced due diligence on high-attention structures such as offshore transfers, and the core is three-way consistency: the bill of lading, the inspection certificate and the payment flow must all agree before title, cargo and funds stand up. SHA-256 anchoring lets each document be verified independently, trading repeated manual reconciliation for a single computation.
