DRDC commissioned this scientometric study on distributed ledger technology (DLT) with a view to understanding the potential impact of new research on future security and defence capabilities and operations. To answer the questions posed in the mandate, publication references from the past 10 years were retrieved and analyzed using text mining software and a variety of information visualization tools. In total, 2,520 journal articles, conference papers, theses, books and government reports were published on DLT in the scientific literature between January 1, 2008 and October 1, 2018, and the number is growing rapidly. Just over 51% have been published so far in 2018 alone, a testament to the velocity of research interest recently. An analysis of an aggregated field of keyword subject groups created from the set of 2520 documents shows that some of the primary topics of R&D interest are cryptocurrencies, data security, applications and the Internet of Things. The top publishing author-affiliations are the Chinese Academy of Sciences (49 publications), IBM (48) and Australia’s CSIRO (36). In Canada, the University of British Columbia is the most prolific entity, with 11 publications. The top military-related organizations in the dataset are China’s National University of Defense Technology (19 publications), the US Air Force Research Laboratory (11) and the US Army Research Laboratory (5). According to the literature, potential applications of distributed ledger technology,
