example （Instance）BI，IP。IPBC Construction ， 1 BC example BI

[0056] When it is necessary to generate an instance (Instance) BI of the block type BC for storing traceability information of agricultural products, execute the block initialization process IP. IP is the constructor of BC, first generate a BC instance BI;

[0057] BI=new BC();

[0058] IP assigns values ​​to each attribute of BH and BB in BI respectively, and sets them as default values:

[0059] BI.BH.BS=0;

[0060] BI.BH.PH=””;

[0061] BI.BH.NC=””;

[0062] BI.BH.HH=””;

[0063] BI.BB.BD=””;

[0064] BI.BB.DH=””;

[0065] After the initialization process IP is completed, the block assignment process AP is started.

[0066] Assuming that the input traceability information of agricultural products is plain text, after serializing it in JSON (JavaScript Object Notation) format, the obtained values ​​are as follows:

[0067] {

Abstract

The invention discloses an agricultural product traceability information storage method based on a block chain, and the method comprises the steps: generating block data comprising the head part of ablock, a block body and other information, and achieving the streaked, normalized and persistent storage of the agricultural product traceability information; information such as a block number and forward Hash is added to the head part of the block, and information such as ontology Hash reality is added to the block body, so that all the blocks form a one-way linked list together. The invention discloses a traditional agricultural product tracing information storage technology. the storage of the tracing data can be realized; query and block-based data integrity verification can be realized;the prevention control, check control and recovery control capabilities of enterprises, consumers and administrative competent departments on agricultural product traceability information are improved, the transparency of the agricultural product traceability information is promoted, and the safety awareness and participation degree of all the society bounds on the quality of agricultural productsare enhanced.

Description

technical field [0001] The invention relates to information acquisition and processing technology in the field of information technology, in particular to a method for storing traceability information of agricultural products based on blockchain. Background technique [0002] At present, with the rapid development of the economy and the continuous improvement of people's living standards, food safety issues have gradually become the focus of social attention. In response to this demand, various ministries, local governments, and administrative departments have begun to pilot the construction of traceability systems in various industries, and have made considerable progress. [0003] Unlike stereotyped packaged foods, the current production process of agricultural products in my country is limited by the scale of production and the level of informatization, and the whole process of information traceability has not yet been realized. In recent years, with the development and ...
