Design of a consensus network reorganization mechanism based on credibility score

Abstract： In view of the dependence of the consensus algorithm on the proportion of benign nodes, a consensus network reorganization mechanism based on credit score is designed, so that the network can quickly repair and reorganize when it suffers from attack or failure, which significantly improves the antiattack ability and service continuity. In this paper, a distributed credit scoring system based on the theory of credit mechanism is developed to evaluate the node reputation in real time and effectively deal with potential malicious nodes. Furthermore, a consensus network reorganization mechanism based on credibility scoring is proposed to enhance the network resilience and security by identifying and isolating malicious nodes. This mechanism designs the network elastic reorganization algorithm, which integrates the redundant setting, fault diagnosis and service node reconfiguration functions to ensure the stable operation of the network and high reliability. This research has important application value in high security needs areas such as financial services, cloud computing and Internet of Things where consensus technologies are widely used.
