Provably Fair Verifier — Verify Your Casino Bets

Here's the deal. Before you bet, the casino locks in the result by creating a Server Seed — a secret string hashed with SHA-256. You get the hash upfront. You can't reverse it, and they can't change it. That's the commitment.

You bring your own seed. Your Client Seed gets combined with the Server Seed and a Nonce (round number). The combination goes through HMAC-SHA256 — a one-way cryptographic function. The output determines your result. Crash point, dice roll, mine positions — all derived from that hash.

After the round, the casino reveals the Server Seed. You plug it in here. If the hash matches and the result checks out, the round was fair. Period. No trust needed — just math.

I've verified thousands of rounds. The math doesn't lie. If a casino's results don't match, you'll know in seconds. That's the whole point of this tool.
