摘　　要：区块链技术与工业物联网(Industrial Internet of Things,IIoT)的融合,为工业领域数据交易和共享带来了革命性机遇.然而,现有区块链模型在IIoT场景下面临着可扩展性、安全和效率的挑战.本文提出了一种基于信用的分布式账本模型CreChain,旨在解决上述问题.该模型通过引入信用账户,优化交易验证过程,实现了高吞吐量和低延迟性能,同时利用Mtree和Credit证明来确保交易安全,保护用户隐私.此外,通过优化信用选择、证明和交换机制,进一步提高了系统性能和可扩展性.实验结果表明,CreChain能够实现20000 TPS(transactions per second)的吞吐量和秒级的交易确认延迟,在共识效率和存储成本方面同样优于主流的区块链扩展方案,能够有效利用区块链实现安全高效的数据交易和共享,使其成为IIoT应用场景的理想选择.The integration of blockchain technology with the Industrial Internet of Things(IIoT)has engendered transformative prospects for the exchange and dissemination of data within the industrial domain.Nonetheless,conventional blockchain frameworks encounter substantial impediments related to scalability,security,and efficiency in the context of IIoT environments.This scholarly inquiry introduces a novel credit-based distributed ledger paradigm,termed CreChain,to mitigate these challenges.The proposed model facilitates elevated throughput and reduced latency by introducing credit accounts and refining the transaction verification mechanism.Additionally,it ensures the integrity of transactions and the preservation of user privacy through the employment of Mtree and Credit proofs.Moreover,the refinement of credit selection,attestation,and interchange protocols augment the system’s performance and scalability.Empirical evaluations demonstrate that CreChain is capable of achieving a throughput of 20000 TPS(transactions per second)and a transaction confirmation latency at sub-second thresholds,surpassing prevalent blockchain scaling solutions in terms of consensus efficacy and storage expenses.This innovation effectively harnesses the potential of blockchain for secure and efficient data exchange,rendering it a promising candidate for IIoT applications.
