Demonstration of Integration of Blockchain in IoT

In the modern era, blockchain technology has achieved a substantial growth with rapid research developments. Blockchain technology is widely used in the field of cryptocur-rency. However, it can also be applied in other field such as internet of things (IoT). In IoT, data security and integrity is a prime concern where many problems exist such as data reliability and unauthorized access. It creates huge problem in deploying an IoT system on a smaller or larger scale. Hence, this paper reports a possible integration of blockchain technology in IoT to create a secure network. To demonstrate this, the game of Tic-Tac-Toe is implemented by following the rules of blockchain. The main goal of this implementation is to explore the application of blockchain in IoT and practically merge these two fields to get the service of IoT with the security and integrity that the blockchain technology promises.
