【Abstract】COVID-19 has made the world realize that the world is a whole, and international trade is the main way to connect countries. With the increase of international trade, the trade data has also become gradually huge. However, the current international trade data is still transmitted using the traditional Internet, which not only is inefficient, but also has poor security. Therefore, this paper aimed to use blockchain technology to explore the big data sharing model and key mechanism of international trade. This paper mainly introduced the design and implementation of a blockchain-based IoT data security sharing system. Firstly, the functional architecture of the prototype system was comprehensively introduced. According to the division of different functional modules, the data interaction design of different modules and the design of related smart contracts were expounded. According to the characteristics of international trade big data, the encryption and decryption algorithms are designed for the transmission of international trade big data. Finally, the prototype system was introduced from data acquisition, experimental environment deployment, system-related functional verification, and performance testing. The experimental test results showed that the encryption and decryption of transaction data by the data security sharing prototype system were more than 2 times faster than those of the traditional algorithm, and the transmission efficiency of the system at different nodes fluctuated within 10%, which showed that the system could perform security interactive sharing of data.
