基于双区块链的产品溯源系统研究与实现
Research and Implementation of Product Traceability System Based on Dual Blockchain
摘要
Abstract
Due to the limited block information storage capacity,the existing blockchain traceability system mostly adopted the combination of blockchain and cloud storage,which could not fundamentally solve the problem of blockchain traceability information storage and data leakage.The dual blockchain mode was constructed,the query chain was used to complete the uploading of traceability information and to realize the basic functions of the tracea-bility system.The storage chain was combined with the interplanetary file system to ensure data integrity and securi-ty.On this basis,the improved capacity proof consensus algorithm was used to ensure the underlying security and meet the application requirements of blockchain traceability system while reducing energy consumption.The test showed that the average upload speed of the system could reach 80.66 M/s,and the average download speed could reach 90.75 M/s,with good upload and download performance.Blockchain transactions per second reached 125.88,and the carrying capacity of a single transaction could meet the demand for block transactions of the trace-ability system.关键词
