An analysis of Blockchain-based IoT solutions to overcome current challenges

With the ongoing boom in IoT technology its usage has increased drastically and that took over a vast range of use cases. As the use of IoT increases over time so does the need to solve the challenges which come with it. Security, Data Privacy & management, and single point of failure are some of those major challenges. A decentralized & distributed technology called blockchain emerges as a workable remedy to this problem. The goal of this paper is to give a review of published papers that provides possible blockchain-based solutions to overcome challenges faced by IoT. This paper analyses the multiple papers to provide a comprehensive survey on security & other improvements achieved in IoT systems using blockchain and the challenges that originate during this integration.
