In order to solve the problems of slow matching between supply and demand, information authenticity and security, and lack of trust in traditional logistics platforms, the author proposes an international logistics management system based on cloud computing technology. The system uses blockchain as the underlying technology, combined with related technologies such as smart contracts and NSGA-II algorithms, 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 network-wide broadcast and consensus, so as to realize the intelligence of the transaction and the nontampering and traceability of the information. The experiment found that in the case set by this example,

, meaning that the final matching result is as follows: P2, the cross-border logistics provider, is matched with U5, the consignor; P3 matches U9, P8 matches U4, P9 matches U3, P1 matches U6, P5 matches U1, P7 matches U2, P4 matches U7, P10 matches U8, and P8 matches U10. Satisfactory matching results show that the algorithm is effective. Experimental results show that the system can increase the transparency and sharing of cross-border logistics information, help to reduce forged data information, improve the level of automation and intelligence, and provide a reference for the application of blockchain technology in the field of cross-border logistics.
