What is Provably Fair?
Provably Fair is a fairness verification mechanism used primarily in crypto gambling that enables players to confirm the integrity of game results. It relies on cryptographic methods to prove that each outcome was generated randomly and was not altered by the casino.
How provably fair works
A provably fair system typically uses a combination of cryptographic elements such as server seeds, client seeds, and nonces. These values are combined through a hashing algorithm to generate a game result that can be verified after the round is completed.
Before gameplay begins, the casino commits to a server seed by publishing its cryptographic hash. After the game round ends, the original seed is revealed, allowing players to reproduce the calculation and verify that the outcome matches the published hash.
Provably fair in gambling games
Provably fair systems are most commonly used in crypto-native games such as dice, crash games, and other blockchain-oriented gambling formats. Some online slots and table-style games also implement provably fair verification methods.
The provably fair mechanism does not change game probabilities or expected outcomes. Its purpose is to provide transparency and allow independent verification of fairness rather than relying solely on trust in the operator.
Provably fair and transparency
By enabling post-game verification, provably fair systems increase transparency and player confidence in game integrity. The verification process is optional but available to any player who wishes to confirm the fairness of results.
Provably fair does not guarantee favorable outcomes or winnings. It only ensures that each outcome is generated according to predefined, verifiable rules.
Frequently Asked Questions
What does provably fair mean in gambling?
It means that game results can be independently verified using cryptographic methods.
Is provably fair the same as RNG certification?
No, provably fair allows player-side verification, while RNG certification relies on third-party testing.
Does provably fair affect game odds or RTP?
No, it only verifies fairness and does not change probabilities or expected returns.
Are provably fair systems used only in crypto casinos?
They are most common in crypto casinos but can be used in other digital gambling systems.
Can players verify every provably fair result?
Yes, verification is possible for each round if the required data is provided.
Does provably fair guarantee winning outcomes?
No, it guarantees transparency, not favorable results.
