Talk on Fungibility, Privacy & Identity

Talk at Tel Aviv Bitcoin meetup, Feb 2014, on “Fungibility, Privacy & Identity”

and slides are here. Take away: counter-intuitively, privacy and fungibility are related but independently configurable properties, plus I argue that identity has no place on the blockchain layer and should be used opt-in where desired, with end to end security, between users at payment protocol layer.
