Integration of IoT and Blockchain Technology for Enhancing Supply Chain Performance: A Review

A supply chain is getting an advantage from the technology's lucidity, less transaction expenses, and real-time data applications. Internet of Things (IoT) and Blockchain technology (BT) has gain remarkable attention by academician and industrial practitioner in recent years as these pair is disrupting a lot of businesses now. BT enables transactional security while IoT connects the physical and digital world with apps and sensors. In this study, a systematic literature review (SLR) is performed to explore the application of integrated IoT-BT in the supply chain and its implementation challenges. The different technologies listed are grouped into the supply chain's five functional fields i.e., responsiveness, intelligence, deductive, surveillance and operational excellence. The result reveals that IoT-BT is mostly used for surveillance purposes and to achieve operational excellence.
