The Internet of Things (IoT) offers connectivity of billions of low-power devices and sensors through the Internet which generates a large amount of data. Recently, blockchain technology is investigated extensively for security and privacy in IoT. In this chapter, we provide an overview of the use of blockchain technology for IoT. First, we analyzed the recent literature for the better understanding of research direction in blockchain for IoT systems. We also present challenges associated with the deployment of IoT and blockchain for the IoT systems. We then discuss two case studies on smart homes and food supply chain traceability to show the effectiveness of blockchain technology for IoT. Finally, we outline the future research directions in this area.
