Problems solved by technology

[0007] However, the information that needs to be shared in the supply chain is relatively scattered and involves multiple departments in the production of the enterprise. Therefore, in the traditional supply chain information sharing, due to frequent changes in the production plan of the enterprise, the downstream enterprises in the supply chain cannot follow up with the upstream enterprises in time. changes, which lead to the role of the supply chain itself not being played

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. (Note: The use of specific cases is just to better explain the present invention, not that the present invention is only applicable to the following cases.)

[0027] Such as figure 1 , figure 2 As shown, this embodiment provides a blockchain-based supply chain status tracking method. First, an information network based on blockchain technology needs to be built. The software and hardware facilities included in this network are: servers for storage, etc., master nodes (related software and hardware facilities) that manage the blockchain, and slave nodes (related software and hardware facilities) that represent each enterprise in the supply chain.

[0028] The method includes the following steps:

[0029] 1. Use the master node to verify the identity of each slave node, and assign a pair of private keys to the slave nodes that have pa...

Abstract

The invention relates to the technical field of information security, and provides a supply chain state data tracking method based on block chains. Enterprises in a supply chain can divide different department information into different business lines according to business conditions of the enterprises, and each business line is divided according to related business logic and becomes different business nodes; and during information exchange, currently happening business node information, related business node information on other business lines and related planned node information happening in the future are sent to downstream enterprises together. According to the method provided by the invention, the information sharing degree between enterprises is enlarged by clarifying the business lines of the enterprises, dividing the business nodes and then associating the business node information, so that the original scattered information becomes more systematic; and secondly, the accuracy and efficiency of information sharing in the supply chain can be improved by verifying repeated node information in the associated business node information.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a blockchain-based supply chain state data tracking method. Background technique [0002] With the development of information technology, the Internet has become an inaccessible part of the development of all walks of life, especially in enterprise information exchange and data sharing. Information and data sharing between enterprises, in addition to the exchange of information such as conventional purchases and transactions, there is also a special information exchange - the supply chain. [0003] The supply chain is a series of related enterprises, through the control of business flow, information flow, logistics and capital flow, from the purchase of raw materials to the manufacture of intermediate and final products, and the delivery of products to consumers. The overall functional structure of enterprises in various links such as distribution. Therefore, infor...
