Problems solved by technology

[0003] However, from the analysis of the current situation, for steel products sold by weight rather than quantity, such as rebar, coiled snails, round steel, and wire rods, steel mills only provide warranty certificates by car number when the steel leaves the factory. When the variety is split and sold, there will be a problem that the original warranty cannot be split, resulting in the lack of warranty for the steel after split sales

Embodiment 1

[0037] Such as figure 1 As shown, the present embodiment provides a block chain-based method for generating and managing a steel material warranty, the method comprising the following steps: building a block chain platform, a steel production organization (steel mill) and a steel sales organization (e-commerce trading platform) ) to access the blockchain platform based on the unique identity authentication information. The unique identity authentication information includes the identity code identity_key and key pair (public-private public_key and private key private_key). Registered blockchain users realize information interaction with the blockchain platform; the blockchain platform receives the steel resource data and steel material protection data encrypted and uploaded by the steel production organization; the blockchain platform receives the steel sales organization’s Feedback the corresponding steel material warranty data after querying the request; the block chain plat...

Embodiment 2

[0048] This embodiment provides a blockchain-based steel warranty generation and management system, which includes:

[0049] The block chain platform is used to realize the information interaction between the steel production organization, the steel sales organization and the steel material warranty management platform. The block chain platform adopts the method of Embodiment 1 to generate and manage the steel material bond;

[0050] The distributed file storage module is used to store the electronic files of the warranty certificate generated by the steel material warranty management platform.

[0051] The method for generating and managing the steel warranty certificate involved in this embodiment is the same as that in Embodiment 1, and will not be repeated here.

[0052] The method and system for generating and managing steel material guarantees provided by the above embodiments have the following advantages:

[0053] The steel mill provides encrypted factory steel qualit...

Abstract

The invention relates to a steel quality guarantee book generation and management method and system based on a block chain. The method comprises the following steps that a block chain platform is constructed, and a steel production mechanism and a steel selling mechanism are connected into the block chain platform; the block chain platform receives steel resource data and steel quality guarantee data which are encrypted and uploaded by a steel production institution; the block chain platform feeds back steel quality guarantee data after receiving the query request of the steel sales institution; the block chain platform receives order data encrypted and uploaded by a steel sales institution; the block chain platform sends a request for generating a quality guarantee book electronic file tothe steel quality guarantee book management platform after receiving a quality guarantee book application request of a steel sales institution; and the steel quality guarantee book management platform generates a quality guarantee book electronic file based on the order data and the steel quality guarantee data, generates quality guarantee book information and uplinks the quality guarantee book information. Compared with the prior art, a real and effective quality guarantee book can be provided for split and sold steel.

Description

technical field [0001] The present invention relates to the technical field of steel industry informatization, in particular to a block chain-based method and system for generating and managing steel guarantee documents. Background technique [0002] When steel products leave the factory, the steel factory will provide a quality assurance certificate, indicating the specifications and performance parameters of the materials used, which has legal effect. Many steel mills use the steel e-commerce trading platform as an important spot sales channel. They place goods on the trading platform and upload the steel quality information. Buyers can obtain the original warranty certificate of the purchased steel after purchasing the steel. In order to make it easier for buyers to obtain warranty certificates, Chinese patent application CN104503715A discloses a dynamic warranty certificate management system for the steel industry, including a warranty certificate structure configuration...
