Abstract
IoT and blockchain are the area that focuses on the security of the data. So many researches are already addressed in this relevant domain. Still there are many opportunities in IoT that need to be addressed [1]. For example, as the number of devices are increasing, the memory space is decreasing, while using the network layer communications protocol for relaying datagram. Its routing function enables internet working, and essentially establishes the internet (IPv4 and IPv6), as well as security issues, such as vulnerable access control mechanisms [5]. This paper’s main objective is to focus on the advantages of blockchain and implement it on IoT. In this research paper, how the combination of blockchain and IoT can create the wonders in the field of data security of smart devices is also discussed. Moreover, based on the past data, some challenges of IoT are also addressed.
