Abstract

The invention provides a pesticide quality traceability system research model constructed based on a block chain technology. Safety and reliability of pesticide quality are ensured, a pesticide quality traceability system hierarchical model is established according to a blockchain architecture (a data storage layer, a network communication layer and an application layer), and the data storage layer and the network communication layer are independent of each other but have a relationship. According to the invention, a blockchain-based architecture is established for the traceability characteristics of pesticide products, is different from a traditional traceability architecture, can realize real-time traceability of the pesticide products, and has the following advantages compared with a traditional traceability method: data can be subjected to multi-point input in the aspects of a data layer and a network layer, and personnel who input the data can be subjected to identity verification; in the aspects of a consensus layer and a contract layer, the formula and agreement of the data can be subjected to rule limitation.

Description

technical field [0001] The present invention relates to the field of information processing, in particular to a data traceability system. Background technique [0002] In recent years, blockchain has been widely used in industry, agriculture, transportation, shopping malls, banks, public security and other fields. It is one of the important means of modern management and monitoring, which greatly improves management efficiency and automation level. Generally speaking, the sharing and traceability query system consists of the following parts: manufacturers, processors, regulatory agencies, transporters, retailers, and consumers. [0003] With the continuous development of the Internet, as well as the development of information technology and network technology, people's demand for data sharing has become more and more intense. In today's global big data environment, people gradually hope to obtain information on all aspects of society through data sharing mechanisms. As far...
