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.
