Abstract
The effective traceability of fire products is an important guarantee to prevent potential safety hazards. Aiming at the problems of unverifiable authenticity of fire product information and insecure data storage, this paper constructs a fire product traceability model and implements a traceability system. The traceability model uses the Internet of Things technology to ensure the credibility of the data source, and stores fire data in combination with blockchain and IPFS (Inter Planetary File System). Meanwhile, the traceability system is designed based on the Hyperledger Fabric architecture to achieve efficient information sharing and traceability management of fire products. The experimental results show that compared with the traditional traceability system, the traceability system has low design and maintenance cost and improved security.
