Class 18: Useful Proofs-of-Work

Posted: Mon 23 March 2015

Schedule

Wednesday's class will be a visit from Josh Cincinnati. You are encouraged to read some of his blog posts before his visit, including Minimalist Socialism through Cryptocurrency and Lenovo Under Sustained Man in Middle Management Attack. Josh graduated from UVa in 2007 (double-majoring in Political & Social Thought and Mathematics) and has been involved in several interesting companies since then.

Next week, each team will have an opportunity to present your project idea. The schedule will be posted separately soon.

Note: due to a bug in slideshare's updated player, ink markings no longer appear in the viewer.
If you download the slides, they are present though. Hopefully, the player will be fixed someday.
