区块链中基于多级委员会的去中心化节点管理方法
A decentralized node management approach based on multi-level committees in blockchains
摘要
Abstract
In response to the challenges of high centralization,low node voting enthusiasm,and vulner-ability to manipulation in committee-based blockchain systems,this paper proposes a decentralized node management method based on a multi-level committee structure.The method introduces a comprehensive node assessment model for preliminary screening of all network nodes,and incorporates a point decay al-gorithm to dynamically elect block-producing nodes,thereby ensuring the system's decentralized nature.Finally,a reward and punishment incentive mechanism is introduced to encourage nodes to maintain ac-tive behavior within the blockchain system.Experiments show that the multi-level architecture and the proposed consensus algorithm improve the decentralization level of the blockchain system compared to similar algorithms,and achieve better performance in terms of resistance to manipulation,block produc-tion speed,node voting enthusiasm,and the speed of malicious node removal.关键词
