Design And Implementation Of A Blockchain-based Luxury Supply Chain Platform

With the growth of the global economy and the improvement of people's living standards,the market size of luxury has expanded dramatically.Although the rise of the luxury market has brought vitality to the economy,it also led to flood of counterfeit luxuries.At present,these counterfeit luxuries on the market are of good workmanship,and the styles are very similar to genuine products,ordinary consumers can be deceived by them.The counterfeit luxuries not only harm the interests of consumers and enterprises,but also seriously distorted the market order.In order to deal with the phenomenon of the flood of counterfeit luxuries,luxury merchants were using a variety of anti-counterfeiting technologies to verify their own genuine products.However,these anti-counterfeiting technologies are not secure: some can be easily imitated by counterfeiting,such as the paper anti-counterfeit labels and identification certificates attached to the products;some have high thresholds,such as the RFID tags based on the Io T.So they have never been effective in curbing counterfeit products in the market.The emergence of blockchain technology can solve this problem.Blockchain is a distributed ledger technology,which has the characteristics of openness,transparency,immutability,and data traceability,the import of smart contracts adds the advantages of autonomy and reliability to the blockchain,thus it is often used in supply chain traceability.In this paper,blockchain was integrated into the supply chain platform as a underlying technology,which makes the information in the supply chain to be stored in the blockchain safe and reliably,realize the traceability,verifiability and anti-counterfeiting of the products,and solve the difficulty in verification of luxuries;Hyperledger Fabric was chosen as the framework for blockchain,multi-channel technology was used to divide blockchain into four channels:supply chain upstream channel,supply chain downstream channel,market channel and query channel,which ensures data sharing,independence and privacy of data in different parts of the supply chain.The main work and result of the paper is as follows:(1)In blockchain layer,docker is used as containers to simulate nodes from different manufacturers to join corresponding channels.By useing the multi-channel feature,mesh storage model is designed and used to store data in the blockchain,which improves the efficiency of tracability of ledgers.According to the different attributes of products in different stages,Golang is used to write specific smart contracts for each channel.(2)In application layer,a B/S architectured system was built using the Spring Boot framework,and five functional modules of the system are designed,all the operations on the blockchain were completely encapsulated in the modules,which is user-friendly.(3)In the completed platform,manufacturers in each stage of the supply chain system can enters the information of the goods into the blockchain by websites,consumers can use the blockchain's tracking and tracing function to look up the genuine luxuries' information.The platform would alert consumers and administrators once counterfeit commodities or suspicious operations were detected,which reduces the number of counterfeit and protect the rights of manufacturers and consumers.
