摘要:
物联网设备数量的激增和中心化的管理架构给物联网的发展带来了严峻的挑战,区块链技术的去中心化和不可篡改等特点可以用来解决物联网的上述难题,故此将区块链技术应用到物联网领域成为研究热点。随着区块链技术在物联网应用中的深入研究,出现了一个新的概念:"物链网"。本文首先介绍了物联网的行业痛点和区块链相关技术,然后分析了将区块链技术应用到物联网领域的论文和白皮书,把融合文献分为平台架构和应用场景两类后,进行归纳总结,并调研了应用领域的典型公链和商业项目,指出了将区块链技术应用于物联网领域所面临的挑战与机遇,讨论了相应的解决方案,最后展望了"物链网"未来的发展趋势,提出未来研究方向应侧重于数据存储和数据管理方向。

Abstract:
The surge in the number of IoT devices and the centralized management structure have brought severe challenges to the in-depth development of the Internet of Things. The decentralization and non-tamperability of blockchain technology can be used to solve the above problems of the Internet of Things. Applying blockchain technology to the field of Internet of Things has become a research hotspot. With the deepening of the application research of blockchain technology in the Internet of Things, a new concept emerged:"BoT". This paper first introduces the industry pain points and blockchain related technologies of the Internet of Things, then analyzes and summarizes the papers and white papers that apply blockchain technology to the Internet of Things field, classifies the fusion documents into two categories:platform architecture and application scenarios, summarizes them, and investigates typical projects and commercial projects in the application field, pointing out that the blockchain technology is applied to the challenges and opportunities faced by the Internet of Things field. The corresponding solutions are discussed. Finally,we look forward to the future development trend of the "BoT" and proposes that the future research direction should focus on data storage and data management.
