Abstract

The invention discloses a reputation evaluation method and system. This method is applied to the reputation evaluation system, including: establishing accounts, nodes participating in network interaction creating their own accounts; transactions between accounts, data transfer and amount transfer between accounts, system status update; account reputation update, after account transactions, Conduct mutual reputation evaluations and form an evaluation matrix, use machine learning methods to predict the comprehensive reputation of each account on the network, and update the system status again; generate block uploads, and when the system completes the reputation update, it will take place within this period Transaction records and system state changes are packaged into a block and uploaded to the blockchain, so that the transactions made by each account can be verified and cannot be changed. The present invention improves the safety, accuracy, reliability and scalability of reputation evaluation, and is suitable for establishing network node reputation evaluations in various scenarios.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a reputation evaluation method and system. Background technique [0002] With the rapid development of network technology, the connection and cooperation between nodes in the network are increasing day by day. There are a large number of untrustworthy transactions and services in the existing peer-to-peer network. How to ensure the authenticity of node interaction data and the credibility of nodes is an important research topic. The reputation system is a system for evaluating the reputation of network nodes. The established reputation system can be used to obtain the reputation of each node in the network, thereby helping network nodes evaluate the credibility of transaction nodes. [0003] In the prior art, there are centralized reputation system and decentralized reputation system. In the centralized reputation system, the reputation of network nodes is stored and ...
