现有区块链溯源系统由于区块信息存储容量有限,多采用区块链与云存储相结合的方式,并没有从根本上解决区块链溯源信息存储和数据泄露的问题.针对此问题构建双区块链模式:查询链完成溯源信息的上传,实现溯源系统的基本功能;存储链结合星际文件系统保障数据完整安全.在此基础上,利用改进后的容量证明共识算法保证底层的安全性,在减少能源消耗的同时满足区块链溯源系统的应用需求.测试结果表明:系统上传平均速度可达80.66 M/s,下载平均速度可达90.75 M/s,具有良好的上传和下载性能.区块链每秒交易量达到125.88笔,单次交易承载量可以满足溯源系统的区块交易需求.
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.
