Internet of Things (IoT) is now in its initial stage but very soon, it is going to influence almost every day-to-day item we use. The more it is included in our lifestyle, the more will be the threat of it being misused. There is an urgent need to make IoT devices secure from getting cracked. Very soon IoT is going to expand the area for cyber-attacks on homes and businesses by transforming objects that were used to be offline into online systems. Existing security technologies are just not enough to deal with this problem. Blockchain has emerged as the possible solution for creating more secure IoT systems in the future. In this project, first an overview of the blockchain technology and its implementation has been explained; then we have discussed the infrastructure of IoT which is based on Blockchain network and at last a model has been provided for the security of internet of things using blockchain. The purpose of this work is to provide guidance for the use of blockchain technology, through cases to make a more secure and trustable IoT model IoT has numerous applications, for example: in making smart homes, Smart City, Improving Health, Autonomous Vehicles, etc. Some IoT devices are currently available in the market like Wearables, Smart Thermostat Systems, Air Conditioners, and refrigerators that use Wi-Fi for remote monitoring. Apart from all these benefits, IoT has some serious issues, which should be sorted out before it gets implemented, like the technologies on which the foundations of IoT have been established have several bugs, so if hackers get access to the system through these bugs, then they can compromise the privacy of the customer or even can cause harm to them. Thus, before implementing IoT, the security of these systems should be strengthened and made free from any bugs. Keeping the IoT device secure is one of the most difficult tasks to accomplish. In making these devices cheap, small and easy to use many security policies are compromised which increases the risk of security breach.
