The best overview I’ve seen so far on the subject of cryptography for blockchain is by Christian Cachin of IBM Research in Zurich.
The video is available here: http://brightcove04.brightcove.com/hd2/o1/2360034885001/2360034885001_5220794209001_5220774962001.mp4
and the companion PDF is available here: http://tle.atlanta.ibm.com/replays.html?type=ems&id=EF0C1C3C0849804A8525804C000940EA
