I am pleased to post Show # 238, May 27, my interview with Prof. Arvind Narayanan of Princeton University on Bitcoin, cryptography, privacy and web transparency. Arvind does a range of information policy-related research and writing as a professor affiliated with Princeton’s Center for Information Technology Policy (CITP). [Note: I am a Visiting Research Collaborator at CITP]. Through studying the operation of and security challenges surrounding the cryptocurrency Bitcoin, Arvind has been able to assess cryptography as a privacy-enhancing and dis-intermediating technology. To that end, we had a wide-ranging discussion, from the varied roles of cryptography to commercial surveillance and transparency. Because Arvind is such a dynamic and interdisciplanary scholar, we had a wonderful discussion that I hope you enjoy!
