A new era awaits the development of cryptocurrency and blockchain technologies. This study highlights the influential and conceptual aspects of blockchain and cryptocurrency literature with bibliometric analysis. There are 1965 related documents from 2015 and 2020, represent various structures and technologies, cryptocurrencies, and blockchain applications. We have deployed “bibliometrix 3.0”, the r-package, and VOS viewer to analyze key literature aspects. IEEE Access is the core journal for cryptocurrency and blockchain publications. The University of Cagliari, Notreported, and Peking University are key affiliations, and the USA, China, and India are core countries for literary research. H. Wang is the core author with the central theme of security of blockchain technologies. It is a set basis for conceptual aspects, core, and future research streams and themes. The study proposes three research streams: the structure of cryptocurrencies and implications of blockchain technologies, privacy, security management of data and information, and development of optimal information systems. The study further segregates themes into highly centralized and motor themes that are also core themes. Topics related to Consensus protocols, proof of work, distribution ledger technology, blockchain, and cryptocurrency procedures and structure comes under core themes. Highly developed and emerging themes are considered as a stepping stone for future directions. Underlying topics are related to fintech, Islamic finance, valuations, and dynamics of cryptocurrencies.
