Here is the PDF of their paper: http://www.arijuels.com/wp-content/uploads/2013/09/public_gyges.pdf "The Ring of Gyges: Using Smart Contracts for Crime.". This is definitely a paper worth reading.

Subject: Your paper on criminal contracts

Dear Professors Juels (http://www.arijuels.com/) and Shi (runting@gmail.com), and Ahmed Kosba akosba@cs.umd.edu : I've found a reference to your recent paper, http://www.initc3.org/publications.html. "The Ring of Gyges: Using Smart Contracts for Crime." Perhaps you are not aware, but 20 years ago (1995-6) I wrote an essay on a very similar subject. I called it "Assassination Politics". cryptome.org/ap.htm . Jim Bell
