about provably fair:
bitcoin game with Provably fair!
Your game is not provably fair. I could copy your game and generate a losing result for the player 100% of the time while it would still "verify" according to your method. I can do this by simply using a slightly different time, because there is NO fixed time on a transaction.

I have explained this multiple times now:

You cannot use timestamps if you want to be provably fair. There is no fixed timestamp at bitcoin transactions. There can be a 0 - 10 second delay EASILY between when a bitcoin node gets the transaction. You could maliciously change the timestamp to 1,2,3,4.. seconds later to make the player lose. There is no way for the player to verify if you did this. Therefor it's impossible to generate a provably fair outcome with this.

I am not saying you are a scam. I am also not saying that you are cheating. I could believe that you are honest. But provably fair is not about believing or trusting.

Provably fair is a way for the players to verify and prove if they have been cheated or not. On your site, they cannot verify and prove this, because using "timestamp" is unreliable as shown in my previous posts. Therefor the player just has to trust you to be fair.

That is "trust us, we are fair" and not "provably (=you can prove we are) fair".

And in more detail starting from: https://bitcointalk.org/index.php?topic=1666167.msg17188778#msg17188778


Since you continue to ignore me and claim that this game is provably fair (while it really is NOT provably fair AT ALL), I will add negative trust too. Your game doesn't have to be provably fair, but if it's not, you should not promote it as provably fair.
