Abstract - The Internet of Things (IoT) is a network connected objects like sensors; actuators, electronics and software that are future requirements of any industry and modern society. These embedded systems are made to provide state-of-the-art facilities to exchange data over the internet. IoT technology can be efficiently used in various sectors like agriculture, healthcare, transportation, water and wastewater management, product manufacturing, power generation & distribution etc. Blockchain has emerged as a key technology is quickly rising to the top, especially considering its widespread use. The integration into workplace networks still faces some difficulties. IoT raises security and privacy issues because data authentication and exchange are handled solely through the central server. The main server model and blockchain technology is added while a component about IoT to label such certainty and problems. Three primary characteristics, namely, extensibility, inactivity, and network longevity, impact security measures without them, internal attack mitigation would be difficult. Using block chain can upgrade net conservation, efficiency and certainty. Recovery after events is fairly simple because the block chain stores the entire history of modifications to device configuration.
