An Enterprise Credit Evaluation Method for Power Grid Service Providers Based on Block Chain is Presented

Abstract

As the main content of credit investigation, credit management is an important part of enterprise operation management, and it plays a dominant role in the management of enterprise personnel, funds, contracts, bidding and other management. The management of credit is essentially the management of data. Traditional credit investigation agencies collect user data through various technical means and establish a credit investigation management database. However, the reliability of data obtained in this way is not guaranteed. The emergence of blockchain theoretically solves the problem of data reliability, and provides a new method for credit investigation, but it can not guarantee the authenticity of the data itself, that is, the nodes that get the accounting can upload the fake data content to the blockchain without verifying the data content itself. How to reduce the damage caused by this uncertainty to the operation and management of enterprises is a major scientific problem that urgently needs to be solved. Therefore, this paper will make research on the consensus mechanism supporting the reliability of data content and the data standardization technology of uploading to blockchain. The main research content includes: 1. Propose a dynamic weight voting consensus mechanism based on incentive mechanism; 2. Propose the standardization technology of data uploading to block chain based on smart contract.The proposal of two technologies provides theoretical support for the authenticity and standardization of blockchain data content. Finally, taking the power grid bidding management as an example, based on the consensus mechanism and the standardization technology of data uploading to block chain proposed in this paper, construct a power grid service provider credibility evaluation model.
