In 1v1 pvp games, there is no need for a fair system, because you and the player can verify, the results immediately.
If a 1v1 pvp game, was rigged, it would be immediately uncovered.
Likewise, 1v1 pvp games, do not require provably fair, to the extent of casino games, like slots.
Because all results, can be cross checked and pen tested by users immediately, without a fair system.
Just providing this information, so users are aware, of this update, in gambling overall.
I am inherit about this, because pvp games, are a better way to gamble.
Versus having the casino siphon your money, and disperse it in areas, you are not familiar with.
At least with 1v1 pvp, games, I can invite my friend, well run a game for 5$ and check the system out.
And immediately, we know if something is wrong, because if the money didn't go to one of us, who did it go to?
Something is wrong, something is rigged, let's not play here, johnny.
Users can work together, to discern these legitimate sources.
It is up to these pvp organizations, to provide you chatrooms, so you can then verify in chat, if you lost, 'Johnny did you get the money?'
If johnny says no and he won, then something is up.
Likewise, if you win, and don't receive anything flag it.
Working together like this, we don't need to read complex code, or hash algorithms, to decipher, the legitimacy, of results.
perhaps are you playing coinflip or you are playing something like case battles. if you are playing coinflip you are 50 50 to get 100% of your amount (- casino house edge, but you get what I mean) and if you are playing something like case battles you are 50 50 to get your "victory" but you don't know the amount you'll get. that's why provably fair is needed there.
