This mixing of algorithms and gambling in the provably fair section got me wondering: Couldn't one set up a kind of market for randomness? Basically you could buy and sell a variance in exchange for an expected value, and people that agree on a trade send bitcoin (or whatever) to a third party, which then draws and pays out the corresponding amount to each party. It would make for some moderately interesting math, I wonder if there would be an interest in such a service? Basically casinos could then wrap this marketplace and have people gamble, with their expected gains being at a sort of market optimum.
