Maybe I'm just being a bit thick, but how exactly is this a peer-to-peer casino project when you literally state in your post that it has a client-side and a server-side application to it? This sounds more like open source software that allows casino owners to run a casino server, but it doesn't sound like it's peer-to-peer.
I think p2p here means person-to-person games where players play against each other and not against the casino and not peer-to-peer system where nodes connect directly to each other without the need for a server. (maybe OP can clarify this point)
What concerns me in such games is how the provably fair algorithm works and how random numbers are generated! Also, how to know you are betting against a real player not a bot created by the casino?
