I intend to focus on Bitcoin network privacy - which is currently woeful (IMHO) - with some discussion of "off-blockchain" transactions. Possibly coffee time and a question/answer session might help us to get to know each other as well. Otherwise, I'm open to suggestions. It's hard to pick spectacular topics without knowing all of you a little better. Bring yourself, and your ideas to contribute if you want to contribute. I'll happily cede time to anyone with an interesting or helpful topic.
