A couple of questions:
Is it coded entirely in php?
Is it all proprietary code (user authentication, etc.)?
What system does it use to process bitcoin transactions?
What is the maximum number of bets / second you were able to get out of it?
No this is java version.
Yes, it's a closed-source code written exclusively for fastbluff. It doesn't have 2fa authentication implemented, yet.
Currently it uses client on server.
You can set it at 7-8 bets per second but you'll need fast server.
