Natural rubber trades at 19,260 yuan a tonne. A single 5,000-tonne bonded warehouse receipt therefore carries a value near 19,260 × 5,000 ≈ 96.3 million yuan, tying up a sizeable credit line.

Pledge loans used to settle at T+3 because title confirmation waited on three separate documents — the warehouse receipt, the bank's internal review and the customs release — all arriving together. Whichever link stalled, the cash sat three extra days, and the same credit rolled one fewer cargo.

Now each batch's intake, inspection and ownership are turned into a SHA-256 fingerprint computed in the browser and written to the chain. The bank receives not a stamped PDF but a receipt it can re-compute on its own, so confirmation drops from three days to the same day and the loan lands at T+0.

Turnover moves from 9 times to above 10 times, letting the same credit roll one more cargo cycle. Cross-chain recognition lets that receipt circulate a second time between two banks without re-inspecting the goods or re-running confirmation at every hop.
