PROVABLY FAIR
Fairness should be checked, not merely promised
EZPoker uses a commit-and-reveal process: a cryptographic commitment is created before the hand, future cards stay secret while play continues, and verification data is revealed after the hand.

1. Commit before the hand
The server creates the random seed and deck, then calculates a cryptographic commitment tied to the hand and room. The commitment represents the chosen deck without revealing it.
2. Protect unknown cards during play
Publishing the seed or full deck before the hand ends would expose future community cards and private cards. Only the commitment is shown while the hand is active.
3. Reveal and reproduce the check
After the hand, the disclosed seed and deck can be recomputed against the earlier commitment. A match shows that the committed deck was not replaced during the hand.
What this proves—and what it does not
The check is designed to detect a changed deck after commitment. It does not make claims about player skill, outcomes, or profit, and it must be described separately from any optional chain anchoring status.
FAQ
Frequently asked questions
Why not reveal the deck before the hand?
Because that would expose future community cards and potentially other players' private cards. The commitment can be public without revealing the deck.
What does a matching commitment show?
It shows that the revealed verification data reproduces the commitment recorded for that hand.
