重构图视角下超级账本在物联网的应用研究综述

在部署基于区块链的物联网应用中，出现了缺少细粒度隐私保护、事务处理效率低、高延迟、灵活性和动态性不足等方面的技术阻碍。为进一步推进区块链技术在物联网的普及和应用落地，致力于企业级标准的区块链技术的超级账本引起了研究界的广泛关注。然而在当前的研究中，缺少针对基于超级账本的物联网的客观综述。旨在以独特的视角回顾超级账本在物联网领域的研究。为展示更直观的差异和提供技术融合流程，提出了重构图的分析方法。重构是将文献中核心设计和原架构图融合，重新构造可以展示文献核心思想图的过程。这种方法旨在将文献的核心思想可视化。最后，从低功耗共识算法、智能交易验证、链上链下混合存储和自定义激励机制四个方向对超级账本在物联网的未来研究进行展望和总结。

Survey on application of Hyperledger in IoT from perspective of reconstructing diagrams

In the deployment of blockchain-based IoT applications, technical hindrances in terms of lack of fine-grained privacy protection, low transaction processing efficiency, high latency, and lack of flexibility and dynamism have emerged. To further promote the popularization and application of blockchain technology in IoT, the Hyperledger dedicated to the enterprise standard blockchain technology has attracted wide attention from the research community. However, there is a lack of objective review for Hyperledger-based IoT in the current research. This study aimed to review the research on Hyperledger in the IoT domain with a unique perspective. In order to demonstrate more intuitive differences and provide a faster process of technology convergence, this study proposed a reconstruction diagrams analysis method. Reconstruction is the process of merging the core design of a literature with the original architecture and reconstructing the diagram that shows the core idea of the document. This approach aimed to visualize the core ideas of the literature. Finally, this article prospected and summarized the future research of Hyperledger in IoT in four directions: low-power consensus algorithm, intelligent transaction verification, on-chain and off-chain hybrid storage, and custom incentive mechanism.
