Abstract The Internet of Things (IoT) refers to a network
concept that extends its clients to any item for information exchange and
communication. Blockchain is a new application paradigm of distributed data
storage, point-to-point transmission, consensus mechanism, asymmetric
encryption, intelligent contract and other computer technologies. Blockchain
technology for IoT has been a hot topic in academia and industry. This paper
mainly summarizes the main existing research results of the challenges faced
by IoT, the technical characteristics of blockchain, the advantages of
applying blockchain technology in IoT, security challenges (key management,
intrusion detection, access control, privacy protection) and the technology
to deal with them. Finally, the prospect of this industry would be summarized
and discussed. On the basis of this study, we hope to put forward suggestions
and provide references for future research orientation. Keywords: Internet of Things (IoT), blockchain,
