Research on Grain Supply Chain Information Collaboration and Sharing Network Based on Blockchain
The guarantee of national grain security and the development of modern agriculture rely on an efficient grain supply chain information collaboration network.Backed by the strong encouragement of na-tional policies,new generation information technologies such as cloud computing,big data,the Internet of Things,and blockchain are being gradually integrated in-depth with traditional agriculture.In the face of is-sues such as information silos,information distortion,information traceability,and node trust in grain supply chain information collaboration,we can leverage the technological strength of blockchain such as distributed ledger,asymmetric encryption,and smart contracts to ensure data authenticity,timely information sharing,and traceability.It can specifically address the problems existing in the information collaboration and sharing process,promote information collaboration among various nodes in the grain supply chain,and provide tech-nical support for optimizing China's grain supply chain.First,after clarifying the information and entities involved in grain supply chain information collaboration,this paper analyzes the compatibility of China's grain supply chain with the blockchain technology;secondly,starting from the existing problems in China's practice of grain supply chain information collaboration and sharing,in combination with the characteristics of the blockchain technology and the information character-istics of the grain supply chain,it constructs four different structures of blockchain architecture,namely main grain supply chain,node operation side chain,demand preference side chain,and government supervision side chain;and finally,utilizing the blockchain cross-chain technology,it forms the grain supply chain infor-mation collaboration network that combines the four chains and analyzes the information sharing process of this collaborative network to achieve collaborative sharing of information among multiple entities in the grain supply chain.The grain supply chain information collaboration and sharing network constructed in this paper is mainly examined in its theoretical support and technical compatibility.However,in its specific implementation pro-cess,the willingness of various entities to participate in information collaboration,the value distribution be-fore and after information collaboration,data standards in the information collaboration sharing process,and the construction of relevant legal and regulatory systems may all affect the construction and development of the grain supply chain information collaboration network.Therefore,future research should not only ex-plore the willingness of various entities to participate and the distribution of value in conjunction with practi-cal issues but also actively give play to the guiding role of the government,accelerate the construction of rele-vant laws and regulations in the information field,and protect the rights and interests of various entities,thereby promoting the substantiation of the blockchain-based grain supply chain information collaboration and sharing network.
