Fire Equipment Information Traceability System based on Blockchain

To solve the problems of centralization, tampering, incomplete storage, and privacy fire fighting equipment traceability system, this paper proposes a information system based on blockchain. The is developed Fabric blockchain platform Hyperledger. environment equipped with three organizations: manufacturer, dealer, consumers, query request initiated function in chaincode. Finally, through certificate authentication user account can realize inquiry, response time average value 19.5 ms. characteristics are difficult to tamper with, timestamp transaction traceability, which be well applied equipment, makes more perfect, consumers get all information, including production logistics usage equipment.
