Direct answer (as of 31 Aug 2026)
Provably Fair is not a badge. It is a SHA-256 handshake: you receive the hash of the server seed before the wager, then recompute the result from server seed + client seed + nonce. Stake Originals and Beef original titles post that hash. A GLI certificate on a closed RNG can still be honest. It is not something you can recompute. Evolution live is that closed feed — isolation is a different test.
Hash vs PDF
The protocol, per the NIST SHA-256 family: commit (hashed server seed) → bet → reveal. If the revealed seed does not match the hash, the operator cheated in public. Centralized RNG sends a payload to a vendor server and returns a result. You trust the lab.
| Operator | What you can check (31 Aug 2026) | RTP lock | Status |
|---|---|---|---|
| Stake | SHA-256 on Originals | Player-checkable; some titles ~99% | Pass |
| Beef | On-chain hash on originals | No local slider | Pass (no recovery if flagged) |
| BitStarz | Closed provider RNG, server-lock | No operator slider | Pass (cert, not a hash) |
| Retail cage (typical) | PDF / “certified RNG” | Slider 96% → 92% | Fail |
The Fail is the slider, not a missing logo. You still eat every dead spin on the low profile.

A certificate is a third party saying the box is fair. A hash is you checking the box. Do not confuse the two on a seven-figure turnover.
