Abstract：With the development of economy，consumers’demand for fresh food is increasing day by day，and the cold chain logistics that fresh products must go through has the characteristics of low temperature and complexity，so it is difficult for consumers to understand the production information of products and protect their own rights and interests. To solve the problem，the cold chain traceability information system is designed by using the tamper proof characteristics of blockchain. Ranking，which is according to the number of occupied blockchain nodes，is made to drive the manufacturer record nodes. In addition，the system mainly realizes the production reporting process of manufacturers and product information query function of the public. This system can better strengthen the management of cold chain products and effectively realize the traceability of cold chain products.

Keywords：blockchain；cold chain traceability；food safety；information system
