The Research And Implementation Of Wine Anti-Counterfeiting Traceability System Based On Blockchain

In recent years,with the continuous improvement of the material level,the demand for consumer goods(such as wine)other than daily necessities has grown rapidly.Because of the large profit margin of wine,counterfeit and shoddy products are endless.In response to the problem of counterfeiting,some large companies use the wine anti-counterfeiting system to maintain the brand image and safeguard the vital interests of consumers.The research and application of anti-counterfeiting traceability system has been developed so far,the existing technology has been relatively mature,but the current market economy environment has not been applied to a large scale,the reasons include the high cost of system implementation and the authenticity of consumers’ traceability information.Not recognized,etc.Blockchain technology is a distributed account book technology that combines multiple technologies.It has the characteristics of de-trust,decentralization,and non-tamperability.It has received extensive attention from national and international scientific research organizations.Blockchain technology has the natural advantage of being able to solve the problem that the traceability system data is easily falsified,data integrity is not guaranteed,and the structure is centralized.This paper introduces the architecture model and technical characteristics of blockchain,analyzes the feasibility and technical advantages of using blockchain technology for wine anti-counterfeiting and traceability,and discusses the process of combining blockchain technology with wine anti-counterfeiting traceability system.Write,broadcast,verify and trace between transaction information.According to actual needs,the Hyperledger Fabric blockchain development platform was selected as the underlying framework,and Kafka clusters were deployed on multiple Ubuntu 16.04 servers to meet the minimum requirements of the Kaflca consensus mechanism.Design the wine anti-counterfeiting trace block alliance chain,introduce the Fabric-ca sub-project to complete the dynamic management of the block alliance chain account,and realize the storage and traceability of the transaction information between the links in the wine supply chain on the blockchain.The research in this paper shows that by combining the blockchain technology with the wine anti-counterfeiting traceability system,the information of the wine in the entire supply chain is jointly maintained by the whole block alliance chain,which reduces the centralization degree of the traceability system.The record of information on the blockchain must be agreed by all nodes to form new blocks for storage,and to achieve reliable and complete traceability of wine information.Meet the needs of the consumer market.As the research on blockchain technology continues to deepen in the industry,the performance of blockchain applications will inevitably improve,and the authenticity of source data of blockchain will inevitably be more guaranteed.
