Commodity anti-counterfeit traceability method and device based on block chain, and node of block chain

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. [0003] In the pro...

Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found that the traditional technology has at least the following problems: the anti-counterfeiting traceability information of commodities is easy to be forged or tampered, and such phenomena are unfair to users themselves
