IoT Blockchain for Smart Sensor

The Internet of Things (IoT) started as one of the main driving forces of Industry 4.0. Having had its initial phase with results clearly visible still today, we are now beginning to witness the maturity at which this technology can reach. This sophistication of IoT will be made possible with the help of other emerging technologies. Among these technologies is Blockchain. This technology is the ideal candidate to counter the flaws of IoT, among which there is security. This paper proposes a functional infrastructure model that employs IoT smart sensor nodes to monitor environmental parameters such as temperature and pressure. On top of this base architecture a Blockchain network is deployed to mitigate the native vulnerabilities of IoT and to ensure that data collected is decentralized, accessible, transparent, lightweight and scalable.
