With the rapid development of e-commerce,the logistics industry has also developed rapidly.Internet + logistics will quickly integrate e-commerce and logistics companies,express and express delivery,forming a huge modern logistics industry,a large number of logistics companies for China's economic and social development Played a huge supporting role.However,at present,the logistics industry service transaction system is highly centralized and has poor coordination capabilities.Information flow,capital flow,and logistics need to pass the certification of the logistics center node.The information cannot be transparent,traceable,irrevocable,and the security of customer information is not effective.Protection,etc.,affect the information security,automation,and intelligence of logistics company service transactions.Blockchain is one of the hot technologies in recent years.Its essence is a huge decentralized distributed ledger database.It has the characteristics of decentralization,detrusting,non-deterrability and encryption.The application of blockchain technology to the logistics industry can greatly address the logistics scale and geographical expansion faced by modern logistics,the dramatic increase in the scale and complexity of data storage,the establishment of a trust mechanism,the protection of personal privacy,and the reduction of transaction costs.Decentralization,non-modification,information traceability,transaction transparency,breaking industry barriers,promoting fair competition,and bringing positive and disruptive changes to the logistics industry.Therefore,under the cloud computing environment,the application of blockchain technology to the study of consensus algorithms for logistics service transactions has very important scientific and application values.Firstly,the status quo of the research on blockchain technology in logistics supply chain at home and abroad is analyzed,and the significance of the research on the logistics blockchain consensus algorithm is explained;the problems existing in the traditional logistics service transaction process and the blockchain technology are analyzed.In solving the problems of logistics service transaction problems,the basic idea of using cloud computing and blockchain to solve its existing problems is given.Combining the technical advantages of cloud computing and blockchain,the definition of logistics blockchain,cloud logistics blockchain,logistics blockchain cloud computing model and related theories are proposed.Then,according to the basic principles of the practical Byzantine consensus algorithm and the logistics blockchain cloud computing model,combined with the decentralized and non-repudiable information security theory,a cloud blockchain-chain block consensus algorithm is proposed and Map Reduce of the algorithm is proposed.Parallel processing functions such as design and algorithm analysis.Finally,under the Hadoop environment,experiments and comparisons are made between the algorithm and the original practical Byzantine consensus algorithm and the optimized Min BFT algorithm.Experimental results show that the proposed algorithm is superior to the practical Byzantine consensus algorithm and optimized Min BFT algorithm.Therefore,this algorithm is an effective blockchain consensus algorithm in logistics service transactions.The main innovations of this article include:(1)The concept of logistics blockchain and cloud logistics blockchain and related theories are proposed.(2)A logistics blockchain model based on cloud platform was established to realize real-time status simulation of virtual logistics nodes on the cloud platform,hash encryption operations,digital signatures,distributed billing,decentralization of data storage,non-deterrence,traceability Such as logistics blockchain distributed billing consensus process.(3)A cloud block-based consensus algorithm for the logistics blockchain is proposed,and parallel processing functions such as Map and Reduce are constructed.Map functions are used to implement dynamic node allocation,broadcast communication,block encryption transfer,and Reduce function map node status information to achieve practical Byzantium.Mechanism consensus process to solve the problem of data block security trust in logistics blockchain.
