Woofun AI reports that Shanghai has deployed the initial batch of blockchain-based digital warehouse receipts for non-ferrous metals. The initiative utilizes the "Warehouse Registration Chain," which operates on the national "Maritime Trade Chain" infrastructure and was initiated by the Commodity Warehouse Receipt Registration Center. Sinograin Group's Global Futures Delivery Business Headquarters issued these receipts, establishing a closed-loop on-chain process that covers issuance, registration, and cancellation.
