As the data market becomes ubiquitous, it is necessary to study the data streams generated by Internet of Things (IoT) devices. For example, nowadays, security problems are crucial to the process of data transaction. Due to the decentralization of blockchain and difficult data tampering, blockchain can well solve the security problems in data transaction. However, the transaction efficiency of blockchain can hardly meet the current market due to latency and other problems. This article mainly reviews existing research on blockchain and IoT data and put forward possible solutions for dealing with some of the current problems. The present study is mainly divided into three parts, including the classification of research problems, research methods, and the classification of experiments. The main research questions are about insufficient functionality and poor performance on the Internet of Things and data markets. In addition to the discussion on whether to use blockchain, this article also proposes some feasible research directions for future research.
