Research And Design Of Cross Border Logistics Platform Based On Blockchain Technology

With the deepening of globalization,China's import and export business volume has a breakthrough growth.However,relevant research and data show that,although the market scale of cross-border logistics industry in China is increasing year by year,there are many problems in cross-border logistics platform,such as asymmetric information of both sides of the transaction,difficult logistics information traceability,confused industry standards,lack of trust foundation,long settlement cycle and so on.Therefore,it is necessary to study how to solve the difficulties and pain points of traditional cross-border logistics platform,improve cross-border logistics efficiency and reduce costs.Due to the decentralized way to build trust,blockchain technology has the characteristics of openness,network wide consensus,transparent transaction,non tampering and full traceability,which can effectively solve the problems in the cross-border logistics industry.Based on the theory of blockchain technology and logistics platform,this paper designs and constructs a cross-border logistics platform based on blockchain technology,which can effectively solve the problems of information authenticity and security,lack of trust and so on in traditional logistics platform.The platform uses blockchain as the underlying technology,combines intelligent contract and Web3 and other related technologies,matches the supply and demand sides of cross-border logistics resources,writes the important information generated in the platform transaction into the blockchain,and carries out the whole network broadcast and consensus,so as to realize the intellectualization of the transaction and the non tampering and full traceability of the information.After the completion of the design,the platform can increase the transparency and sharing degree of cross-border logistics information,reduce forged data information,improve the level of automation and intelligence,and provide reference for the application research of blockchain technology in the field of cross-border logistics.The main work of this paper is as follows.(1)This paper analyzes the current situation and main problems of traditional crossborder logistics platform.Firstly,it studies the current situation,platform participants and sub subject business processes,analyzes some pain points and difficulties in the operation of traditional cross-border logistics platform,and lays the foundation for the introduction of blockchain technology into cross-border logistics platform according to the needs of existing consensus building system,platform user matching,customs participation,crossborder Logistics information and cross-border payment.(2)Build platform system architecture based on blockchain technology.This paper analyzes the basic functional requirements and the overall architecture of the platform for daily operation,and proposes a five tier platform architecture combined with the hierarchical structure of blockchain technology.In the main function module design of the platform,the main organization function structure diagram of the platform is established;In terms of the design of blockchain smart contract and platform database,the order contract and settlement contract are designed respectively,and the way of combining blockchain storage with platform server storage is proposed to store the important information generated in cross-border logistics activities in the blockchain through smart contract,while the basic information is stored in the platform database,In order to improve the efficiency of blockchain.Finally,the paper constructs the algorithm model of cross-border logistics service transaction matching under the blockchain,selects the use satisfaction index and designs NSGA-II algorithm to solve the problem of crossborder logistics service transaction matching under the blockchain,so as to make the cross-border logistics platform based on blockchain technology more in line with the actual needs.(3)This paper uses an example to test the matching algorithm of cross-border logistics based on blockchain used by the platform,and packages the matching results into the blockchain to realize the related functions of intelligent contract.The cross-border logistics platform based on blockchain technology is compared with the traditional platform,and the results show that the cost,information,customs clearance,security,and service efficiency of the platform are improved after using blockchain technology,Efficiency and other aspects have certain advantages.
