High-credibility steel hanging identification method and system based on blockchain evidence storage verification

Abstract

The invention relates to a high-credibility steel hanging identification method and system based on blockchain evidence storage verification. The method comprises the steps that a blockchain platform,a warehouse information system and a steel sales platform are constructed and accessed to the blockchain platform; after the steel enters the warehouse, the warehouse information system acquires thesteel information of each operation link in real time, and uploads the steel information of the key operation link to the block chain platform for evidence storage to generate evidence storage information; the steel sales platform receives a merchant hanging request and sends a verification request to the blockchain platform; the block chain platform verifies the evidence storage information of the to-be-mounted steel, determines whether the to-be-mounted steel is high-credibility steel or not, generates a verification result and returns the verification result to the steel sales platform; andthe steel sales platform receives the verification result, and if the steel is high-credibility steel, a reputation identifier is added to the hung steel. Compared with the prior art, higher credit endorsement is provided for high-quality steel resources, the credibility of steel resource information is ensured, the communication cost in the transaction process is reduced, and the transaction efficiency is improved.

Description

technical field [0001] The invention relates to the field of information technology in the iron and steel industry, in particular to a high-reliability steel identification method and system based on blockchain storage and verification. Background technique [0002] With the continuous development of the Internet, steel transactions in the bulk field have also been online. Among them, Ouyeel Cloud Business, Zhaogangwang, and Steel and Silver E-commerce are all leading steel e-commerce platforms in the industry; online steel transactions have a relatively difficult The problem to be solved is how to ensure that the online information is consistent with the real thing. [0003] Taking a steel network as an example, it clearly stated in its transaction rules: "All information, materials, goods and services displayed are provided by the merchant itself. Unless otherwise expressly stated in writing, it is not right to find steel network on the platform. Information, materials, g...

Problems solved by technology

To a certain extent, this model ensures the authenticity of some basic information such as cargo rights and weights of steel coils, but due to the limitations of warehouse management, other more steel coil information cannot be obtained;

[0005] At the same time, in order to seek personal gain, some merchants maliciously tampered with quality information, brand names, specifications and other information, laying many hidden dangers for subsequent transactions and production links
