信誉驱动的区块链分片共识及激励机制设计
Design of reputation-driven blockchain sharding consensus and incentive mechanism
摘要
Abstract
The PBFT(Practical Byzantine Fault Tolerance)consensus algorithm was confronted with several chal-lenges in the blockchain sharding environment,including high communication complexity,random leader election,node insecurity,and insufficient participation incentives.To address these issues,a reputation-driven blockchain sharding consensus and incentive mechanism was proposed.Reputation mechanisms were utilized to evaluate and incentivize node behavior,thereby enhancing system trust and promoting active participation.Aggregated signature technology was employed to merge consensus node signatures,and node voting weights were determined based on reputation assessments,which reduced communication overhead and improved consensus equality and security.Ad-ditionally,a deposit and incentive mechanism was introduced under reputation management,where initial entry standards were set and gradually increased over time according to reputation values.Differentiated incentive mod-els,based on node roles,were designed to balance stable income and dynamic rewards,thereby continuously im-proving network stability and security.Simulation results demonstrated that the proposed R-PBFT consensus algo-rithm outperformed the traditional PBFT,maintaining lower latency and higher throughput,which effectively en-hanced system performance.Furthermore,compared to proportional incentive allocation based solely on reputation,the proposed incentive mechanism achieves higher consensus participation rates.关键词
