provably fair was invented for the player and imo the best invention in gambling business so why to do it away? please correct me if I am wrong
You bring up a good point.
When I first published the side-channel attacks a couple years ago, some casino operators dismissed it by saying things like, "We would never cheat," or "if we did this, we'd get caught" or "if we were caught, we'd lose all our players," without addressing their implementations of provably fair. So, they are countering a cryptanalysis with a PR/marketing spin, which doesn't make sense.
By saying, "We would never cheat," without addressing their implementation, they are only offering a simple promise of fairness, which is no different than a non-provably fair casino.
This is the same type of deflection Nitrogensports is infamous for. They have a clearly rigged Blackjack system but whenever anyone questions it they link to "provably fair". Good to see hard data out there that doesnt make the Casino skeptics looks crazy.
