Embodiment Construction

[0034] Blockchain is a technical solution like a non-relational database, not a specific technology. Blockchain technology can be implemented through a variety of programming languages ​​and architectures. Compared with traditional databases, blockchains are immutable. A blockchain consists of several blocks. Each block stores several transaction data (messages). Hash calculation (Hash Function, also known as hash function) is performed on the data of each message and the processed messages in the block to obtain the corresponding hash value. In this way, within a block, the change of any message will lead to subsequent changes in the hash value. Therefore, the hash value within the block can be used to verify the validity of the block data and be used to link the next message. Blocks are processed in a similar way, that is, each block performs hash calculation with the hash value of the processed block to generate a new hash value, forming a layer-by-layer nesting relatio...

Abstract

The invention discloses a product traceability verification method based on block chain technology, including a traceability step and a verification step, wherein the traceability step is as follows: 1) Construct a block of plan and production process information data and store it in a private block chain ; 2) Construct verifiable label information from the three basic information; 3) The distribution node adds the product consumption information and the label information to the public blockchain; the verification steps are as follows: a. Obtain the product label ; b. Query the product label in the public blockchain; c. Determine the authenticity and uniqueness of the product according to the product label and the related records of the public blockchain. Adopting this method can ensure the authenticity and reliability of the traceability information obtained, and solve technical problems such as product duplication, spam, and failure to bind the responsible person. At the same time, the invention can ensure the efficient operation of the traceability system and control costs.

Description

technical field [0001] The present invention relates to the specific application technical field of block chain technology, in particular to a product traceability verification method based on block chain technology. Background technique [0002] Product traceability is an important means of modern supply management. As food safety and other issues are getting more and more attention from the government and the public, information application technology in the field of product traceability (such as food and agricultural product safety traceability) is developing rapidly. At present, the mainstream product traceability system is mainly centered and led by relevant government departments or a certain core enterprise, using administrative means or market position to force relevant upstream and downstream enterprises to cooperate in accordance with their specifications, and product traceability records are provided by a certain department or company There are security risks such...
