区块链溯源在白茶中的应用

Blockchain provides tamper-proof trust for white tea traceability. Applications: (1) Garden registration—GPS coordinates, cultivars, planting area recorded on-chain; (2) Picking records—date, batch number, picker info written to blockchain; (3) Processing records—withering time, drying temperature, tea maker parameters on-chain; (4) Storage records—IoT sensors automatically upload temperature/humidity data; (5) Distribution records—every link from factory to consumer recorded on chain. Consumers scan QR code to view complete traceability chain. Some top Fuding enterprises have piloted blockchain traceability, but industry-wide adoption faces high costs and data input authenticity challenges. GeoMind's supply chain has pre-built blockchain traceability interfaces.
