RNG (Random Number Generator) vs Provably Fair
What each means, how they relate, and when to use which.Both aim to make outcomes trustworthy, by different means. An RNG produces random results and is trusted through independent certification. Provably fair is a cryptographic method, common in crypto casinos, that lets a player verify each individual result was not tampered with. One relies on lab attestation, the other on math the player can check.
The software (or hardware) that decides the unpredictable outcome of a digital gambling game — which cards, reel stops, or numbers come up — so every result is down to pure chance.
Use it when Use RNG for the generator behind random outcomes, trusted by certification.
Full definition of RNG (Random Number Generator) →A cryptographic scheme that lets a player verify a game round's random outcome was committed before betting and not altered afterwards.
Use it when Use provably fair for the crypto method that lets players verify each result themselves.
Full definition of Provably Fair →The key distinction
- An RNG is trusted via third-party certification; provably fair is verifiable by the player directly.
- Provably fair uses cryptographic seeds and hashes; a standard RNG does not expose per-bet proofs.
- Provably fair is associated with crypto gambling; certified RNGs are the mainstream standard.
