On an unrelated note, can anyone explain how site seed being known can cheat the gambling site? Doesn't JD and LN publish the site seed?
I am not 100% sure about ED, but for PD the bet result is determined by sha512(secret, server seed, client seed).
The "secret" are different for each day, and will only be revealed after the day.
Only sha(server seed) will be published before your bet, but not the server seed directly.
Client seed can be set by the player himself.
So, with only server seed and client seed, the player still shouldn't be able to know the bet result beforehand...
