Integration of Blockchain and IoT (BIoT)

Abstract

The internet of technology (IoT) refers to the connectivity of smart devices with the internet to accumulate data and transfer it to smart devices. But with the lack of built-in security measures, IoT is vulnerable to privacy and security threats. Blockchain technology assists in the security needs of IoT devices. The main characteristics of blockchain technology like immutability, transparency, auditability, and encryption of data sort out the inadequacy of IoT devices. This chapter represents an inclusive survey on blockchain and IoT technologies with the integration of these technologies to overcome the shortfall. This chapter includes an overview of both technologies with their advantages and disadvantages. It also highlights the domains of their applications and represents the advantages of integration of blockchain and IoT technology to develop BIoT (blockchain-based IoT). Also, it analyzes the main challenges faced during the smooth integration of blockchain and IoT technologies.
