A Blockchain-based Framework Of E-commerce Supply Chain

With the rapid development of e-commerce in recent years,the collaboration of delivery requests among supply chain participants has also increased,and the establishment of trust among supply chain network participants has become a key issue.Due to cultural,legal and ideological differences between countries,information asymmetry is easy to occur,and information sharing between suppliers is difficult to establish,which makes it difficult to achieve true product traceability in e-commerce.The emergence of block chain technology has introduced a new way of thinking for supply chain management.Blockchain technology provides us a new tool to solve the product traceability problem in supply chain management.This research focuses on the e-commerce context,to propose a blockchain-based framework,and develop a set of corresponding techniques and methods for achieving traceable products and transactions in supply chain management.A general blockchain-based product traceability framework is introduced.This framework is based on a e-commerce supply chain context,incorporating a series of blockchain-based models,including multi-chain structure model,data management model and block structure model.Several core methods and algorithms are also developed,such as information anchoring method,key distribution method,information encryption algorithm and anti-counterfeiting method.The framework,models and methods form a complete and comprehensive solution,which are evaluated by applying to several typical problems and attack cases.The case analysis results show that the framework,models and methods can successfully deal with key recover problem,and protect against clone attack,counterfeit tag attack and counterfeit product attack.The effectiveness,extendibility,security,implementation and governance issues of applying these solutions are also discussed.The new theoretical framework,model and method proposed in this study also have certain reference value for the study of supply chain management.A formal solution to the problem of product traceability and information sharing in supply chain management is proposed.The application of several typical problems and cases proves the feasibility and effectiveness of the method.These models and methods form effective and complete solutions to typical supply chain management problems and provide important methodological enlightenment for supply chain management research.
