If you know much about the bitcoin world, implementing a new "cryptocurrency" is not exactly a technical challenge. I never created one because I could have done so during any one-week or so period of time. The problems were entirely legal.

Also note that my primary goal, misunderstood by everyone but Yishan, was not just to make reddit notes work, but build reddit's cryptofinancial system. p2p payments on reddit had enormous potential, now substantially delayed.
