Problems solved by technology

However, changing the block structure will increase the block information, resulting in a waste of space resources
On the other hand, it is often difficult to simply use blockchain technology for data traceability due to the need to ensure that it cannot be tampered with.

Embodiment Construction

[0071]In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementations obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0072]In many areas of industrial production, there are many needs related to the traceability of goods or goods information. When a commodity or a good is purchased by a consumer, it must go through a series of processes such as selection of raw materials, processing and production, logistics and transportation. The data in this process can be stored and stored uniformly through data tamper-proof methods such as blockchain. Management, but how consumers or...

Abstract

The invention relates to a traceability information verification query method, device and equipment based on blockchain. The method comprises the steps: constructing a blockchain based on preset nodesand preset trust relations, wherein the blockchain comprises at least two organizations, and the trust relations comprise the trust relations between the preset nodes, the trust relations between thepreset nodes and the organizations and the trust relations between the organizations; constructing a data center node in each organization, wherein the data center node is used for storing data; receiving a traceability verification query request, wherein the traceability verification query request carries request query node information; based on the blockchain, performing verification query of different modes according to the request query node information and the trust relationship. Different types of nodes and data center nodes in a chain are constructed, the data center nodes only store message abstracts of batch data in a blockchain, a data center periodically performs self-inspection to recalculate the message abstracts, multi-mode verification query is provided according to different trust degrees of nodes requesting query to the data center nodes, and convenience and quickness are achieved.

Description

Technical field[0001]The invention belongs to the technical field of regional chain databases, and specifically relates to a method, device and equipment for verifying and querying traceability information based on blockchain.Background technique[0002]Blockchain is a shared database. The data or information stored in it has the characteristics of "unforgeable", "full trace", "traceable", "open and transparent", and "collective maintenance". In recent years, due to the emergence of cryptocurrency, blockchain has made certain breakthroughs in every technical field. These technologies have a certain help to the anti-tampering of traceability technology. Blockchain technology has gradually been applied in the industrial field, which makes the research focus of blockchain technology gradually become closer to database-related technologies. For example, some methods have improved the area by reordering transactions or data fragmentation. For the transaction throughput of the block chain, ...
