摘　　要：区块链技术近年来受到广泛关注,很多行业都在尝试基于区块链技术解决信息系统中传统中心化方案存在的可靠性与安全等难题。而将区块链网络与行业实体相关联必须依托物联网技术,因此,结合区块链和物联网技术解决不同领域中的多方协作问题是当前的研究热点。另一方面,物联网自身发展也受到中心化架构的限制,如何利用区块链技术解决现有物联网系统的不足也是一个重要问题。尽管当前区块链技术的相关应用非常多,但其中一些应用实际上并不适合采用区块链技术。首先介绍了区块链技术的应用逻辑,然后基于典型案例分析介绍区块链结合物联网的适用场景,最后讨论了4个区块链与物联网结合的共性问题。Blockchain technology has attracted wide attention in recent years,and many industries are trying to solve the reliability and security problems of traditional centralized schemes in information systems based on blockchain technology.However,the connection between the blockchain network and industry entities must rely on the Internet of things(IoT)technology.Therefore,combining the blockchain and IoT technology to solve the pain points of vertical industries is the current research hotspot.On the other hand,the development of IoT itself is also limited by the centralized architecture,and how to use the blockchain technology to solve the predicament of IoT is also an important issue.Although there are many blockchain related applications,some of them are actually not suitable for blockchain technology.Firstly,the proper logic of blockchain applications was discussed.Then suitable application scenarios of blockchain technology were introduced by typical case analysis.Finally,four common problems when combining blockchain and IoT were discussed.
