论文摘要
在过去的十年中，区块链技术在物联网（IoT）系统的研究中越来越受欢迎。作为通过强密码学算法确保的分布式和不可变的分类帐，区块链带来了一个新的视角来保护物联网系统。许多研究已致力于将区块链整合到IoT设备管理，访问控制，数据完整性，安全性和隐私中。相比之下，区块链辅助的物联网通信的研究要少得多。但是，我们看到区块链在分散和确保物联网通信方面的潜力。本文提出了一个由财团区块链技术提供动力的创新物联网服务平台。提出的解决方案摘要机器对机器（M2M）和人与人机（H2M）通信，以提供由IoT设备提供的服务。然后，它通过智能合约和区块链交易来实现IoT网络的数据交换。此外，我们将辅助存储层介绍给提出的平台，以满足各种数据存储要求。我们的概念验证实现已针对不同的块配置下的各种工作负载和连接大小进行了测试，以评估平台的交易吞吐量，延迟和硬件利用率。实验结果表明，我们的解决方案可以在大多数测试场景下保持高性能，并为优化区块链配置以实现最佳性能提供有价值的见解。
Blockchain technology has gained increasing popularity in the research of Internet of Things (IoT) systems in the past decade. As a distributed and immutable ledger secured by strong cryptography algorithms, the blockchain brings a new perspective to secure IoT systems. Many studies have been devoted to integrating blockchain into IoT device management, access control, data integrity, security, and privacy. In comparison, the blockchain-facilitated IoT communication is much less studied. Nonetheless, we see the potential of blockchain in decentralizing and securing IoT communications. This paper proposes an innovative IoT service platform powered by consortium blockchain technology. The presented solution abstracts machine-to-machine (M2M) and human-to-machine (H2M) communications into services provided by IoT devices. Then, it materializes data exchange of the IoT network through smart contracts and blockchain transactions. Additionally, we introduce the auxiliary storage layer to the proposed platform to address various data storage requirements. Our proof-of-concept implementation is tested against various workloads and connection sizes under different block configurations to evaluate the platform's transaction throughput, latency, and hardware utilization. The experiment results demonstrate that our solution can maintain high performance under most testing scenarios and provide valuable insights on optimizing the blockchain configuration to achieve the best performance.
