Although the trust mechanism for agricultural product transactions has systems and laws to endorse the contract, this kind of "credit relationship" and security mechanism lack sufficient trust. Currently, the design of the RFID traceability system is used to solve the problem of data reading, but situation such as data can be tampered with and problem of data security exist. Blockchain is a distributed, shared and encrypted database. Through distributed accounting, a decentralized credit system is established to enhance data security, which is a new mode to save time and costs. In this paper, On the basis of systematically sorting out the focal points and problems of food supply chain system, reanalyzes the framework of traditional food supply chain systems. Moreover, after analyzing the characteristics the blockchain technology, a decentralized credit mechanism of food supply chain is proposed. Furthermore, the traceability of agricultural products based on the blockchain can realize fast and secure authentication permissions and achieve data security in which data cannot be tampered with or forged from anti-counterfeiting, and information privacy is protected.
