Embodiment 1

[0021] Embodiment 1, a blockchain-based decentralized supplier information governance method, the blockchain adopts the alliance chain architecture, and uses the alliance chain technology to manage and share the key information of the supplier. The specific process includes two steps. The first step is to uniquely identify and admit the supplier, and the second step is to conduct a decentralized review of the key information of the supplier; the alliance chain includes management nodes and consensus nodes, the management node is responsible for supplier access review, and the consensus node It is composed of different suppliers and is responsible for reviewing the key information of the suppliers. There are no less than 3 consensus nodes; the architecture of the entire blockchain system includes a data layer, a network layer, a consensus layer and a contract layer. The contract layer is used for various application call.

Abstract

The invention relates to a decentralized supplier information management method based on a block chain, the block chain adopts an alliance chain architecture to manage and share key information of suppliers, and the specific process comprises two steps: 1, carrying out unique identification and admission on the suppliers, and 2, carrying out decentralized auditing on the key information of the suppliers; the alliance chain comprises management nodes and consensus nodes, the management nodes are responsible for supplier admission auditing, the consensus nodes are composed of different suppliersand responsible for auditing supplier key information, and the number of the consensus nodes is not less than three. The method comprises auditing and recording supplier key information by using broadcast and accounting modes of a block chain; eliminating information distortion and asymmetry of the supply chain by utilizing a node peer-to-peer relationship in the block chain; and recording all operation processes of the key information by utilizing the block chain, so that subsequent tracing is facilitated, information tracing of the industrial chain is comprehensively supported, and tampering and repudiation are prevented.

Description

technical field [0001] The invention relates to a blockchain-based decentralized supplier information management method, which belongs to the technical field of blockchain. Background technique [0002] At present, the number of patents using blockchain for data governance and information governance is relatively small, and "201910779290.7 A Data Governance System Based on Blockchain" is relatively close to the content of the present invention. The current literature and patent content lack the combination with specific scenarios, and it is difficult to combine the technical characteristics and advantages of blockchain with the characteristics of application scenarios. 2) The selection of scenarios is unfavorable and the technology is difficult to adapt; 3) The degree of integration between technology and business is insufficient. [0003] With the integration and development of the new generation of information technology and the physical industry, the continuous refinemen...
