Yes, its possible I remember hearing a similar discussion in bustabit or bustadice chat room (forgot which one) and they explained this kind of provably fair to one of their users that was curious. I think you can also find this topic being discussed in their main thread. There's positives and negatives to it but still possible afaik.
the what ? the verfication of bets ? or as known as provaly fair system ? and what is its negative side ? i dont think it has but i can only say that its a good idea that they implement such system because this is for their users to verify if the site is legit or not .
I'm talking about the provably fair part since they've been doing it with bustadice, it's kind of like a multi sig where it's divided to three parties. Here's a quote from bustadice's thread explaining the whole thing.
Enhanced provable fairness
bustadice builds upon conventional provably fair systems to provide additional guarantees to players, investors and the casino itself:
For players: If a dispute over fairness arises with a legacy casino, it's largely their word against yours. In bustadice, on the other hand, all bets are committed to an independent audit server in real-time and can be reviewed and verified by Ryan if need be.
For investors: Neither I nor Ryan can undetectably cheat by predicting future rolls. Assuming you trust the two not to collude, investing becomes provably fair.
In addition, the casino itself gains increased confidence that all wins are legitimateeven if the game server were to be compromised.
The way we do achieve is by introducing a third party: The auditor (Ryan). Final roll results are computed with input from all three parties: The player, the game server and the auditor. When a server seed is revealed, both the player and the auditor can verify its bets.
