Abstract

The invention relates to the technical field of commodity anti-counterfeiting traceability, in particular to a commodity anti-counterfeiting traceability method based on a block chain and a device thereof, a block chain node. The method comprises the following steps: receiving the two-dimensional code information of the commodity sent by the client, wherein the two-dimensional code information isused for indicating to skip to the anti-counterfeiting traceability page, and the anti-counterfeiting traceability page records the information of each link of the commodity; the hash value to be verified being calculated according to the information of each link in the anti-counterfeiting traceability page. Each block chain node stores a hash list recording the true hash value of each commodity,and the hash list has been verified by the block chain consensus. Whether there is a true hash value corresponding to the hash value to be verified in the traversal hash list; if yes, returning the commodity verification success information to the client; if not, the merchandise verification failure information is returned to the client. Because the block chain has the characteristics of non-tampering, decentralization and high transparency, it can provide reliable anti-counterfeiting traceability information.

Description

technical field

[0001] The present invention relates to the technical field of commodity anti-counterfeiting traceability, in particular to a blockchain-based commodity anti-counterfeiting traceability method and its device, and a blockchain node. Background technique

[0002] How to crack down on counterfeiting and shoddy products from the root cause? Simply verifying product manufacturer information is far from meeting market demand. While anti-counterfeiting can monitor product raw materials, production, warehousing, and logistics information, it has become the main focus of anti-counterfeiting development in recent years. Therefore, many manufacturers put electronic labels with anti-counterfeit traceability information on the products when they leave the factory for users to check. The anti-counterfeit traceability information can record product traceability information in the links of raw materials, production, warehousing, and logistics information.

Embodiment Construction

[0059] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0060]Blockchain technology, also known as distributed ledger technology, is a distributed Internet database technology. The network built based on blockchain technology can be called a blockchain network. The blockchain network contains multiple blockchain nodes, each node corresponds to at least one blockchain, and each blockchain contains at least one block . Blockchain technology has the characteristics of decentralization, openness and transparency, non-tampering, and trustworthiness. Therefore, the application field of blockchain technology is becoming more and more extensive.
