ABSTRACT

Blockchain originated from Bitcoin. Bitcoin system is an electronic cash system, in which the concept of blockchain was put forward. Then blockchain technology was applied to Ethereum until the enterprise-level development platform super ledger appeared. Faced with the problem that agricultural products information resources are too scattered, the combination of blockchain technology and Internet of Things technology has solved the bottleneck of traditional agricultural products traceability system in data transmission, data storage and security mechanism. This paper constructs a flexible and credible traceability system model of agricultural products based on blockchain technology. The architecture model includes application layer, platform layer, data center and other parts. In the data access layer, each link of agricultural products supply chain needs to input the industrial and commercial information of the corresponding enterprise, and some of the information is accessed through the Internet of Things, which mainly includes the growth environment and logistics information of agricultural products raw materials. Smart contract is the chain code installed on the blockchain, and its main function is to provide the interface for operating blockchain services. The system performance test shows that the system meets the requirements of practical application.
