Abstract

Since the Internet of Things (IoT) technology has developed rapidly and been widely used in various fields, issues such as identity verification, data privacy, network security, that need to be considered by IoT will become more important in the distributed environment. And these problems can be effectively solved by introducing blockchain technology into IoT. In this paper, we briefly describe the basic concepts of blockchain and application scenarios of blockchain in the IoT, and review some current relevant research works, among which the works on underlying technologies of blockchain IoT and the problems and challenges faced in the blockchain IoT are emphasized. The work of this paper will provide reference value for the future researches of blockchain IoT.

Key words： blockchain; Internet of Things (IoT); system architecture; consensus algorithm; smart contract
