Innovating mainstream technologies such as the Internet of Things (IoT) and Blockchain Technologies (BCT) are witnessed as technological breakthroughs with the potential to revolutionize our society. IoT is envisaged as a global network infrastructure that has outstretched the communication and information sharing not to just between typical computers and humans, but also numerous daily usable dumb objects. Although IoT’s benefits are limitless, it has to face various scalability and security challenges for smooth adoption in real-world implementations. This also encumbers the proliferation of IoT applications in a large scale. However, these two technologies include technically dissimilar philosophies. BCT competence can be used as an integral part of resolving many shortcomings of IoT applications. This research work incorporates these two diverse technologies where BCT is employed in the context of IoT to provide a secure decentralized architecture to resist vulnerabilities and privacy threats.
