Abstract: 【Purpose/significance】In light of the information asymmetry between the agricultural supply chain and financial institu⁃ tions, in order to assist financial institutions and the government in macro-controlling the production and management of the agricul⁃ tural supply chain, increase the availability and productivity of small farmer financing, and encourage the incorporation of small farm⁃ ers into agricultural modernization.【Method/process】We proposed is a blockchain-based prototype of an information sharing for the agricultural supply chain finance. Hyperledger Fabric is utilized as the underlying technology foundation to effectively link the agricul⁃ tural supply chain, government agencies, and financial institutions for information exchange. And investigate the influence of block⁃ chain technology on the resolution of the finance problem by means of an evolutionary game.【 Result/conclusion】On the one hand, the blockchain platform can promote multiple part authentication and sharing of credit information, reducing the financing risk faced by fi⁃ nancial institutions; On the other hand, through reputation incentives and government subsides, it can enhance the financing enthusi⁃ asm of all parties, further enhance the inclusiveness of rural finance【. Innovation/limitation】In comparison to conventional agricultural supply chain finance, we are able to achieve information sharing and real-time monitoring using mechanisms such as chain-specific real-time data, traceability, tamper-prevention, and transaction channel isolation. In addition, we give specific solutions and counter⁃ measures for the creative growth of agricultural supply chain financing on this platform from the standpoint of game theory. However, we do not give the utilization cost and hardware infrastructure of blockchain technology in agricultural production sufficient attention.
