Internet of Things (IoT) is a network of physical devices connected through the internet to collect data and make intelligent decisions. It is a rapidly growing field throughout the world and coming up with rapid growth in research fields as well. It enables us to globally access, monitor, and control these devices.However, the lack of internal security measures puts IoT at risk, and its excessive use contributed to various security and privacy challenges. These shortcomings of IoT can resolve if we integrate blockchain technology with IoT. Blockchain technology is a secure decentralized database management system that stores data in terms of blocks. This study demonstrates a brief review of blockchain and IoT integration. The main contributions of this article are: (i) the advantages of merging both technologies, (ii) the challenges of integrating both Technologies, (iii) Use of blockchain and IoT in education sector, and (iv) future enhancements of IoT with blockchain.
