一种信誉机制的区块链分片重组模型
Reputation-based blockchain sharding reorganization model
摘要
Abstract
Currently,bitcoin and other mainstream cryptocurrencies face significant scalability challenges due to their single-shard blockchain architecture.To address this limitation,sharding technology has emerged as a promising solution for improving blockchain scalability.However,it also introduces a range of new technical and security challenges.Existing sharding approa-ches often overlook the effects of disparities in reputation,communication latency,and node distribution across shards,which can result in performance imbalance and potential security vulnerabilities.Moreover,full-scale sharding reorganization entails substantial computational and temporal overhead,thereby reducing overall system efficiency.To solve these issues,this paper proposed a reputation-driven sharding reorganization model for blockchain systems.The model employed a constraint-based op-timization algorithm to allocate nodes with varying trust levels to appropriate shards,thereby achieving balanced sharding repu-tations and enhancing overall reliability.Theoretical analysis and experimental evaluations demonstrate that,compared with conventional sharding methods,the proposed model significantly improves both throughput and latency performance while re-ducing the sharding failure rate.Furthermore,the model enables dynamic node load balancing,mitigates the risks of node cen-tralization and collusion attacks,and ensures robust dynamic security for the blockchain system.关键词
