Provably Fair Verifier
Enter server and client seeds to independently verify game outcomes from provably fair crypto casinos.
What Is Provably Fair?
Provably fair is a cryptographic system used by crypto casinos to prove that game outcomes weren't manipulated. The casino provides a server seed hash before the game, you provide a client seed, and after the game the full server seed is revealed — letting you independently verify the result.
1. Casino commits to server seed hash2. You set a client seed3. Combined → game outcome4. Casino reveals server seed → verify!

Note: This tool uses a simplified educational demonstration of provably fair algorithms. Real casino implementations may use different derivation methods (e.g. HMAC-SHA256 or specific byte extraction). Always use the official verifier provided by your casino to get exact results. This tool is for learning how provably fair works.
