Surfing Blockchain wave, or drowning? Shaping the future of distributed ledgers and decentralized technologies

Blockchain is a promising technology whose four TRs (TRaceability, TRacking, TRansparency, TRrust) features are bound to revolutionize material, information, financial flows and transactions inside and outside organisations. Many studies have been published showing the potential of this disruptive technology in many fields and this enormous amount of papers calls for a more systematic approach to analyse the overall trend in this research field. In this paper, a bibliometric approach based on performance analysis and network analysis techniques is used to examine the evolution of blockchain technology research. Firstly, this paper contributes to the body of literature by discussing the most influential countries, authors, subject areas and journals of the current blockchain research. Secondly, this paper identifies six main clusters of blockchain-related research contributions and, based on the analysis on centrality and density measures, it classifies research themes in motor themes, basic themes, emerging or disappearing themes, and specialised themes. Practitioners and policy makers may exploit the results of this research to rethink many traditional processes in the light of blockchain technology implementation, exploit the benefits of the four TRs to manage processes, automate common tasks, generate actionable results, and improve everyday operations.
