Embodiment 1
[0066] 1. Blockchain
[0067] In 1991, Stuart Haber and Scott Stornetta first proposed the encryption protection chain product of the block, and then published by Ross J.Anderson and Bruce Schneier&John Kelsey in 1996 and 1998 respectively. Satoshi (Satoshi Nakamoto) first promoted the blockchain as the underlying technology of the Bitcoin payment system in 2008. In the process of Bitcoin circulation, the blockchain is used as the data record support, and the nodes are selected to store and verify the data. Different The nodes are restricted by the consensus mechanism, enjoy the same power over data, have all the information on the entire blockchain, and can verify each other. It is this kind of distributed node verification, which greatly improves data security and data credibility compared with traditional data storage models. Therefore, as a technology in which data is shared on the network through a protocol (consensus mechanism), blockchain's security, credibility, and t...

The invention belongs to the technical field of information processing, and discloses an agricultural product traceability information processing system and method based on a block chain, and the system comprises: a data collection module which is used for collecting production enterprises, production links, logistics information, consumption features and related information; a data processing module which is used for generating a Merkel tree based on a block data processing technology and series hash, stamping a timestamp and processing the data by an asymmetric encryption technology; a dataverification module which is used for performing data verification on the authentication node of each link through a consensus mechanism; and a data feedback module which is used for feeding back datato a production enterprise and performing agricultural product traceability and logistics management at the same time. The invention discloses a set of data structure conforming to agricultural product traceability, which takes agricultural product production enterprises as main data sources and is matched with logistics tracking information and sales information to ensure that reliable information traceability from farmland to dining tables is provided for consumers.
Description
technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a blockchain-based agricultural product traceability information processing system and method. Background technique [0002] At present, the commonly used existing technologies in the industry are as follows: the process of agricultural informatization in my country is tortuous and bumpy. Due to the existence of many uncertain factors in the seasonal, regional and periodic attributes of agricultural production, it is impossible to quantitatively analyze the various aspects of agricultural production. The development process of mutual influence, different data centers have huge differences in data interaction and data sharing due to different data collection modes, which is the main reason for the difficulties in agricultural informatization. In addition, farmers' Internet thinking is backward, especially in the central and western regions, where the educ...
