| 中文摘要: |
| 近年来，随着数字货币的日益兴起和商业应用，区块链技术越来越受到政府部门、工业界以及学术界的关注和认可。与此同时，移动通信网络的快速发展和广泛覆盖，促使物联网（IoT）逐渐走入日常生活，极大程度地提升了工作效率与生活品质。然而，物联网场景中仍存在能效性低、数据传输安全性差等问题，使用区块链技术可有助于促进物联网更好地发展和普及。本文对区块链技术在物联网中的应用进行了系统性综述，首先介绍了背景知识和相关研究，其次提出了区块链的基础架构模型，并且详细阐述了区块链技术应用于物联网各场景的发展现状以及相关特征，最后讨论了一些挑战及未来发展趋势。 |
| 英文摘要: |
| In recent years, with the increasing rise and commercial application of digital currency, blockchain technology has attracted attention and obtained recognition from government departments, industry and academia. At the same time, the rapid development and extensive coverage of mobile communication network have prompted the Internet of Things (IoT) to gradually enter daily life, which has greatly improved work efficiency and quality of life. However, there are still some problems in the IoT scenario, such as low energy efficiency and poor data transmission security. The blockchain technology can help to promote the better development and popularization of the IoT. In this paper, we systematically review the application of blockchain technology in the IoT. Initially, the background knowledge and related researches are introduced. Then, we propose an infrastructure model of blockchain, and elaborate the state-of-the-art and related features of blockchain technology applied in various scenarios of the IoT. Finally, some challenges and future development trends are discussed. |
