Based on blockchain, Hainan Free Trade Port Information Platform Architecture Design

With the country actively promoting the construction of Hainan Free Trade Port, cross-border e-commerce is developing rapidly, and there are many supply chain-based supply chain information service platforms. However, under the background of Hainan Free Trade Port, technical breakthroughs are needed on the pain points such as inefficient information service, untidy information sharing, authenticity to be verified, weak openness and low payment security. Because blockchain technology decentralization, openness, autonomy, non-tamperable digital transparency, traceability and so on can effectively solve the problems of cross-border e-commerce, many scholars have also carried out a lot of research and analysis. In promoting the construction of smart free trade port, this paper analyzes the pain points of cross-border e-commerce and supply chain information services, studies the advantages of blockchain technology applied to supply chain information service platform, and designs the blockchain and supply chain information service platform suitable for Hainan's local development in combination with the FTZ policy.
