Cryptocurrency Cabal will be offered in Fall 2015. It is listed as a cs4501 (Special Topics in Computer Science) with class meetings Mondays and Wednesdays, 2:00-3:15pm in Olsson Hall 120. The expected background for the Fall 2015 course is having completed cs2150 and cs3102 (or equivalent experience and knowledge in some other way). Exceptions will be made for students who bring some other interesting background or perspective to the class.
This site is all the materials from the Spring 2015 course. The syllabus for this semester's course will change some for the next version of the course, but that page and the rest of the material on this site will give you a good idea what to expect.
