From the thesis: "In 2022, the Biden administration published an executive order in which the growing use of digital assets was deemed a national security threat. While this thesis focuses on cryptocurrency, it is more broadly about how the United States can--and should--employ a whole-of-government approach to counter a continuously evolving and adapting threat environment. This thesis begins by examining several assumptions regarding malign actors' adaptations, the adoption and use of emerging technologies by these actors, and strategies for the United States in applying its instruments of power to combat these developments. The research assumes that many adversarial entities engage in multiple activities, such as terrorism, insurgency, and criminality; as these organizations form new alliances, they are also developing new evasion techniques; and this increasingly amorphous threatscape, defined by new malign alliances and technological tools, will require the United States to utilize the entire homeland security enterprise, from the Department of Defense to law enforcement, to confront these actors. This thesis utilizes these assumptions as a foundation to construct an informed policy options analysis that puts forth potential, long-term frameworks to counter this growing diversity of threat actors and their use of increasingly technical and sophisticated tools of evasion."
