Research on International Trade Settlement and Tracking System Based on Blockchain Technology

The research on international trade settlement and tracking system based on blockchain technology aims to solve the problems of low efficiency, lack of transparency and data security in the traditional cross-border trade settlement process. By introducing distributed ledger technology, the system can realize real-time tracking of all links of cross-border trade, ensure the immutability of data, and thus improving data transparency and traceability. The application of zero-knowledge proof technology in this system further guarantees the privacy of transaction data, that is, the legality and authenticity of the transaction can be verified without revealing specific sensitive information. This system can not only significantly reduce the trust cost of relying on intermediaries, but also improve settlement efficiency through automated processes. Through simulation analysis, the test results show that the system shows high stability and reliability when processing high-concurrency transactions, especially in protecting data privacy, reducing trust costs and improving settlement efficiency. The precise data analysis of the simulation results further verifies the feasibility and effectiveness of the system in the actual international trade environment, laying a solid foundation for future promotion and application.
