Cryptocurrency and digital currency based on blockchain-enabled IoT: a bibliometric literature review

Blockchain, the mechanism that powers the Bitcoin cryptocurrency, is seen to be both enticing and essential for providing improved security and privacy for a variety of applications in many different fields, including the Internet of Things (IoT) ecosystem. Blockchain has therefore been viewed as a potential technology for IoT since it offers important answers for the digital currency that can handle issues with high maintenance costs, trust and security, and other issues. However, as far as we are aware, no thorough bibliometric analysis has been done in this area. Therefore, this paper has performed a bibliometric analysis of digital currency based on blockchain-enabled IoT between 2015 and 2022 by 1332 articles selected. The Web of Science (WoS), one of the most esteemed databases, served as the study's primary data source. Besides, a network of country collaboration and a network of co-occurrences for co-word analysis was created using the VOSviewer tool. The results showed that the number of cryptocurrencies and cryptocurrency publications on the blockchain had been enhanced quickly since 2018. Computer science, engineering, telecommunications, commerce, economics, medicine, agriculture, and law were among the areas studied in the blockchain domain. Furthermore, China has surpassed the United States as the leading country in terms of total publications and financing for related-topic research. Regarding the total number of citations, 2016 is the most influential, and IEEE Access is the most significant and prolific journal in the number of citations and publications.
