An Exhaustive Analysis on Security Issues concerning IoT using Blockchain

In today's world, the Internet of Things (IoT) has become an important part of daily life. Due to the exchange of information or data generated by sensors and various technologies used in IoT, the safety of an IoT system is becoming a major issue in technology-driven areas. On the other hand, blockchain, which started with Bitcoin, is now being actively explored for smart contracts that remove the need for a third- party and improve processes and transparency in different areas such as asset management, supply chain management, and healthcare networks. Furthermore, it has the potential to improve the quality of analytical systems by enabling users to trace immutable data from beginning to endpoint.The merger of both technologies, IoT and Blockchain, is one of the most noticeable advancements empowering digital transformation in every possible way. Blockchain endorses IoT devices, increasing reliability and clarity in the IoT system. With blockchain, IoT platforms, devices, and apps can run in a decentralized, scalable environment
