Design Of A Fabric Based Cross-border E-Commerce Logistics Quality Traceability System

Since 2010,with the upgrading of domestic consumption background,the demand of consumers is increasing,which also leads to more diversification and diversification of products.In this case,domestic products can not fully meet the needs of domestic consumers.The low efficiency of cross-border cold chain logistics information dissemination leads to the weakening of the reliability of information and the lack of trust among the participants in the logistics transportation chain.Therefore,it is necessary to introduce a logistics chain that can be supervised by a third party to solve such problems.In this study,according to the previous research conclusions,it is proposed that the blockchain system can be combined with the existing traceability system to change the existing regulatory system in traceability.On the other hand,it is of practical and theoretical significance to solve the current trust problem between consumers and enterprises through the deployment of fabric and the design of smart contract.Firstly,this paper analyzes the research background and significance of cross-border cold chain logistics traceability system.Through the discussion of the current situation of cross-border cold chain logistics traceability system in China,this paper summarizes the advantages of this study in solving the problems of consumers'distrust of enterprises,the complex regulatory process of institutions to enterprises,and the trust problems in business groups,It includes the development of cross-border cold chain logistics,the emergence and development of blockchain,and the application of blockchain in traceability system.Next,this paper systematically analyze the application characteristics of blockchain and its application in cross-border cold chain logistics,combined with the existing blockchain framework,and propose that blockchain can make the existing problems better solved on the basis of current research.Combined with the characteristics of fabric's access network environment and high modularity,supporting programming language,and having pluggable consensus mechanism,the system is preliminarily analyzed and judged.At the same time,it splits the data structure and system architecture of the whole cross-border cold chain logistics,designs the structure of the blockchain system,the problem of data link,and completes the explanation of the chain code.Finally,Caliper is selected to analyze the performance of blockchain system.After the performance test,the performance of the system and the reasons for this performance are discussed,including the impact of the performance of fabric itself,the hardware configuration of virtual machine and the size of the block on the overall performance.Combined with the characteristics of fabric,this paper analyzes the key elements that may affect the performance of blockchain,such as block size,request sending speed,etc.,and finally comes to the conclusion that the current system performance has reached a better point of view.At the same time,it summarizes the possible shortcomings of the research,the key problems that can not be solved at present,and puts forward the topics that still need further research,and puts forward some ideas and methods to solve these problems.
