Abstract

Abstract: In view of the information asymmetry and opacity of the existing system for centralizing the regulation of grain reserves, which reduces the reliability of data, and at the same time, the independence of various business links of grain reserve supervision, which brings information islands, a modular, pluggable and configurable model of grain multi-chain reserve management is proposed based on the characteristics of blockchain technology. The model adds channel technology in Hyperledger Fabric to isolate public traceability data and private data. An authorization mechanism for enterprise users is set up. An intelligent contract for authorization information is designed to check and judge the data format in order to secure the chain and so on. Through the construction of the supervision model and the experimental test results, it is shown that the system can well guarantee the data upload, query and safe storage under the condition of complete functions. It also realizes the supervision of the whole process of the data on the chain, the efficient processing and traceability of the problem events. It can enhance the credibility of grain reserve supervision data and ensure the safety of grain reserves.

Key words: blockchain, food supervision, multi-chain, smart contract, IoT (Internet of Things)
