Issues Related to the Use of Blockchains in IoT Applications

Abstract

We are currently witnessing an impetuous development of blockchain technology in various fields like business, supply chains, or personal identity protection. Another technology that is becoming more widespread is the Internet of Things (IoT), which can be found in a lot of smart applications. In this paper, we aim to study how blockchain finds its utility in IoT applications. Finally, we analyze comparatively the reliability and availability of centralized and decentralized blockchain oracle mechanisms that provide data from IoT devices.
