Problems solved by technology

However, this method of pasting two-dimensional codes on fruits and vegetables is prone to incomplete display of two-dimensional codes due to sunburn, insects, etc., which affects scanning. The way of QR code with higher rate is easy to lead to the problem of less stored information

Embodiment Construction

[0054] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0055] figure 1 It shows a schematic flow chart of a blockchain traceability method for agricultural products provided in this embodiment, including:

[0056] S101. Perform distributed identity DID registration on the agricultural products and the participating units in the production, agency and sales links of the agricultural products.

[0057] S102. Issue or verify a verifiable statement for each agricultural product through each DID, and put the verifiable statement of each agricultural product on the blockchain.

[0058] S103. Print a two-dimensional code on the surface of the agricultural product according to the agricultural product printing technology, so th...

Abstract

The embodiment of the invention discloses an agricultural product block chain traceability method and device. The method comprises the following steps: DID registration is carried out for the agricultural product and the participating units in each link of production, agency and sale of the agricultural product. Each DID issues or verifies verifiable declarations for each agricultural product andplaces the verifiable declarations for each agricultural product on the block chain; according to the agricultural product printing technology, a two-dimensional code is printed on the surface of theagricultural product, and a user can obtain a block chain certificate containing the information of the agricultural product after scanning the two-dimensional code, thereby realizing traceability ofthe agricultural product. The embodiment of the invention creates verifiable declaration of agricultural products and their participating units through registered DID through block chain technology, Signature, verification, revocation and possession, and the generation of two-dimensional code to facilitate users to trace the origin of agricultural products, to solve the agricultural products fromthe production to the sale of all links of data easy to tamper with, untrustworthy and difficult for users to obtain information.

Description

technical field [0001] The embodiment of the present invention relates to the field of agricultural technology, and in particular to a blockchain traceability method and device for agricultural products. Background technique [0002] In the agricultural field, the data of the whole process of fruits and vegetables from production to sales often lacks credibility, which involves a variety of technologies, such as traceability technology, information reading and writing technology and printing technology. [0003] Product traceability in traceability technology is the combination of the current advanced Internet of Things technology, automatic control technology, automatic identification technology, and Internet technology, and assigns a unique two-dimensional code or barcode to a single product through professional machinery and equipment as an anti-counterfeiting ID card. Realize "one item, one code", and then collect and track data from various links such as product product...
