Modeling of Grain Reserve Multi-chain Supervision System Based on Blockchain
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.
