Sarah Jane Hughes was a featured speaker at the annual symposium sponsored by the University of Texas' Law School's Texas Journal of International Law. This year, the symposium was jointly sponsored by the Strauss Center on National Security at the LBJ School of Public Affairs and was aimed at Blockchain Technologies and International Law. Sarah Jane's presentation posed two questions: Can blockchain technologies make us safer? Will cryptocurrencies make us less safe? The answers to both questions in her view are YES, and YES.
