How the Stake Game Verifier Works

Stake.com uses a provably fair system based on HMAC-SHA256 hashing. Before each bet, Stake commits to a server seed by publishing its SHA-256 hash. After you rotate seeds and the server seed is revealed, this stake provably fair verifier computes HMAC-SHA256(server_seed, client_seed:nonce) and derives the exact game outcome — proving the bet was never manipulated mid-session.

Steps to Verify

  1. Rotate your server seed on Stake.com to reveal the active seed.
  2. Copy the revealed server seed, client seed, and nonce.
  3. Pick your game on this page and paste the three values.
  4. Click "Verify" — the computed result should match what Stake showed you.

Why Use an Independent Stake Verifier?

Stake ships an in-site verifier, but the whole point of provably fair is that you don't have to trust the casino's own tooling. A third-party stake game verifier re-implements the cryptography from the public spec, so you're auditing Stake's math with nobody's word to take for it. StakeCruncher's verifier is open to anyone — no sign-up, no rate limits, no API keys. Pair it with our Stake RTP calculator to sanity-check realized return-to-player against what provably fair math predicts.

Deep Dive Nonce Scanning

Use Deep Dive mode to scan hundreds of nonces at once. This lets you verify an entire session of bets in one go, checking that every single result across multiple rounds matches the expected provably fair output. Ideal for spot-checking hot or cold streaks.
