Block chain-based credit score generation method and device

Abstract

The invention provides a credit score generation method and device based on a block chain, and the method comprises the steps: obtaining and storing target data, and determining a data type contained in the target data; wherein the target data at least comprises one data type, and the data type comprises a supplier contract type, a supplier competitiveness type and a commodity user experience type; determining a weight value and a scoring formula corresponding to each data type included in the target data according to the intelligent contract model; determining a credit score of the target data according to a scoring formula corresponding to each data type included in the target data; and determining a comprehensive credit value according to the weight value and the credit score corresponding to each data type included in the target data. The target data related to the supplier is processed through the intelligent contract model in the block chain to obtain the comprehensive credit value of the supplier, and the target data and the comprehensive credit value of the supplier are stored at the same time, so that the non-tampering and traceability of the supplier credit information are realized.

Description

technical field [0001] This application relates to the technical field of e-commerce, in particular to a block chain-based credit scoring generation method and device. Background technique [0002] With the rapid development of economy and electronic information technology, supply chain management plays an important role in the development and competition of enterprises. As the source of supply chain management and the end point of supply chain circular feedback, suppliers play a very important role in the process of supplier management, which affects product quality and technology, and restricts the development of the entire supply chain. [0003] The existing database storage technology can see the stored data in the background or in the database, and the staff can intentionally or unintentionally tamper or leak the data; and, in order to achieve data traceability, an additional log record table will be added to record key data The process of being modified, but the loggi...
