Blockchain technology has the characteristics and functions of distribution, information encryption, information irreversibility, intelligent contract, etc. Through improved traceability and traceability, as well as automatic data acquisition and other ways, blockchain helps to reduce the complexity of the supply chain, improve the visibility of the supply chain. Through literature review, it is found that the application of blockchain technology in supply chain mainly includes: improving the transparency of supply chain, to build trust between upstream and downstream; reduce information cost, help to improve the efficiency of supply chain information transmission; help to realize supply chain traceability and tracking function, especially for the food supply chain. Besides, the research on the application of blockchain in the supply chain is analyzed from the aspects of technology, policy, and organization, and it is believed that the technical bottleneck needs to be overcome, other intelligent technologies need to be integrated, and the integration platform of industry-university-research should be constructed.
