What does "provably fair" mean at a crypto casino?
Provably fair is a system that lets you cryptographically verify a casino game’s result was not manipulated after you bet. It’s a feature largely unique to crypto casinos.
It works with a server seed (hashed and shown to you before the bet), a client seed (from your browser, which you can change), and a nonce. After the round, the casino reveals the server seed so you can hash it yourself and confirm the outcome matches what was committed beforehand — proving it wasn’t altered.
Provably fair only guarantees the result wasn’t tampered with; it does not change the house edge. It’s a transparency tool, not a way to win more.
Key points
- Cryptographically verify a result wasn’t manipulated post-bet.
- Uses a pre-committed hashed server seed + your client seed + a nonce.
- You can re-hash the revealed seed to confirm the outcome.
- Proves fairness, but does NOT reduce the house edge.
FAQ
Does provably fair mean a casino is safe?
It proves individual game results weren’t tampered with, but says nothing about licensing or whether the casino pays out. Check those separately.
