“…The blockchain technology became an increasingly popular solution in the past few years (Bahtiyar et al, 2020) for providing decentralized trust and security in many digital systems after its success with Bitcoin (Nakamoto, 2008). As blockchain removes the requirement for a trusted third party in a transaction system, it has been applied in domains such as access management (Di Pietro et al, 2018), digital content distribution (Kishigami et al, 2015), supply chain management (Hofmann & Johnson, 2016), smart contracts in the Internet of Things (IoT) domain (Christidis & Devetsikiotis, 2016), distribution and verification of sensitive business documents (Aitzhan & Svetinovic, 2016), enhancing privacy in healthcare (Yue et al, 2016;Aydar & Çetin, 2020), firmware update of embedded devices (Lee & Jong-Hyouk, 2016) and many more.…”
