Once a month we rent out the Lucky Lab's private room and present on the projects we've been working on as well as various topics related to Ethereum and blockchains in general.

Matt Goldenberg will be going into detail about the reputation and contest system behind his prediction market, Crystal. His slides are available on his website and the presentation will be livestreamed on YouTube. Please watch the EthereumPDX Twitter feed for notifications related to the livestream and for the chance to ask questions of Matt.
