good to know. I have never felt JD to be unfair and am up a fair bit there over a long time betting carefully with some luck. but I don't think it'd be able to be perceived anyway, or at least it would be hard to trust a perception of it being unfair after losing so this type of thing is the only way to really know
Well, the randomness and fairness are independent of each other. Even if Doog would could influence it in a non-random manner, it wouldn't make sense, because you decide "hi" or "lo" when you bet (to be on the safe side, you could vary this randomly). Just write down the server seed hash and after some bets verify it with one of the scripts (reveal the server seed with "randomize"). Mathematically there is no way that you can be cheated, all rolls for you are known in advance with a given server seed, which is proven by the hash. Even if someone knows of a fast SH256 collision algorithm (there is none at the moment), it would be impossible to cheat, because the rolls would be different for other server seeds.
For investors it is more problematic, because in theory Doog could rob them indirectly with fake accounts, knowing the server seed. But unlikely, because it is all peanuts for him
and would negatively affect JD and CLAM, if it comes out.
