Please note that Chicago BitDevs aims at a technical audience. A general expectation is that people are quite familiar with the design, security, and specification of Bitcoin. Everyone is welcome and we encourage newcomers to observe, but it is unlikely that we will spend time answering introductory questions. Newcomers to bitcoin should make sure check out the Bitcoin & Open Blockchain meetup at https://www.meetup.com/Bitcoin-Open-Blockchain-Community-Chicago/ .
Check out https://ChicagoBitDevs.github.io as the meetup draws near for the topic list.
