In this day and age, Internet use is growing, which has led to development of the Internet of Things (IoT), IoT facilitates the communication, computation and coordination of machines and objects. IoT is classified in two types, first is “inside of IoT” and second is “outside of IoT”. Inside of IoT is considered as protocols. Outside IoT is consider as sensor, actuators and other physically components. In inside of IoT, there are protocol stack which have different layers example Application layer, Transport layer, Internet layer and Physical/Link layer. IoT's layers role is to ensure open and effective communication and transaction between two objects and use of different applications to build a continuous bond between them. One of the major concerns on today IoT is to enhance its security, when privacy of network’s users is increased, the reliability of system increases correspondingly. IoT faces many security and privacy issues due to less computation power, heterogeneity, and limited resources available with its devices. Data is transferred among these devices with little or no human interaction. Data Confidentiality and Integrity are very critical parameters and can be achieved by securely sharing information in IoT scenarios. There is a need to mitigate these new threats and vulnerabilities and ensure Confidentiality, Integrity and availability. This paper is going to introduce blockchain of things with the aim of mitigating all possible vulnerabilities and threats associated in IoT Devices by increasing management of these IoT devices.
