Design And Implementation Of Supply Chain Information Sharing Mechanism Based On Blockchain

In recent years,China has shown a rapid and extensive growth trend to intensive and high-quality development.Under the impetus of this environment,supply chain is also developing rapidly,but in the process of development,many problems have been exposed,among which information sharing is the key problem that the supply chain urgently needs to solve.In order to solve the problem of information sharing,scholars have put forward many methods,but there are still some problems such as enterprise distrust and centralization.However,after the emergence of blockchain technology,scholars found that blockchain has the features of decentralization and data transparency,which can solve the problems existing in the supply chain.Thus,the supply chain’s difficult information sharing seems to have found a solution.Based on hyperledger and the characteristics of the workflow engine,this paper design a based on block chain based on workflow and information sharing mechanism,and the mechanism for information sharing of supply chain provides a unified platform,in order to achieve supply chain information sharing,not timely solve business process automation and information sharing and achieving the degree of information sharing,sharing the information.Firstly,the information sharing mechanism provides a channel for both on-chain users and off-chain users to share information,and the information sharing mechanism enables onchain users to realize automatic execution of business processes through workflow engines.Secondly,this paper considers that although the hyperledger can realize information sharing by setting the permission of node users’ information query,there are important information and non-important information in the information shared by enterprises in the supply chain,so the workflow engine is used to design the object information sharing module.The specific information content of supply chain information sharing can be shared in different degrees to ensure the information security of enterprises.Finally,in order to improve the diversification of supply chain information sharing,this paper also designs the "eigenvalue" database,which provides users with a variety of information transmission methods.In addition,according to the designed supply chain information sharing mechanism based on block chain,the supply chain information sharing platform based on block chain is realized.In order to elaborate the implementation method of the platform in the supply chain scenario,this paper takes the rail-highway combined transport supply chain as the application scenario,and applies the existing business process of rail-highway combined transport supply chain to the supply chain information sharing platform based on block chain.Toward by rail transport as a case of the supply chain in detail in this paper,the implementation method,and to show the functions of the platform on the premise of meet the basic function,public transportation in supply chain information sharing platform can achieve basic according to the different roles in different levels of information sharing,business process automation,and improve the timeliness of information sharing,and other functions.
