Abstract: Based on the analysis of the characteristics and problems encountered in the development process of smart agriculture, the solution is discussed by using the characteristics of blockchain technology, such as traceability, decentralization, difficult tampering, openness and transparency. By using comparative method, case analysis method, inductive and deductive method and other methods, this paper explores how to apply blockchain technology to smart agriculture and how to better serve smart agriculture from the production, circulation, processing, financial services, consumption and other links of smart agriculture industry chain. The flow chart is used to analyze the logical process of the blockchain technology to solve the bottleneck of the development of smart agriculture, and at the same time, it discusses how to use the blockchain technology and smart agriculture to help solve some problems encountered in the practice of targeted poverty alleviation. Finally, some challenges that may be encountered in the application of blockchain technology in smart agriculture are summarized and corresponding countermeasures are proposed.
