Abstract: 【Objective/Meaning】As the upgrading of fresh goods consumption market, cold chain logistics has become the focus of society in China. It is supposed to be effective for the disadvantage of cold chain logistics for agricultural products, i.e., low efficiency, lack of trustworthiness, to integrate blockchain technique with cold chain logistics. 【Methods/Procedures】Based on the blockchain theory and method, the technology of blockchain was applied into the cold chain logistics system of agricultural products.【Results/Conclusions】The application assumption and development idea of blockchain in cold chain logistics were put forward in this paper. As a new technical support for cold chain logistics, blockchain has important application value in the field of cold chain logistics, which is expected to reshape cold chain.
