About CCF
Verifiable fairness for crypto casinos
The Crypto Casino Foundation is the independent body behind the CCF RNG-certification standard — and CCF Labs, the lab that runs the tests. We exist so players never have to take a casino's word for it; they can check for themselves.
Our Mission
Make fairness something you can verify, not just trust
The crypto gambling space grew fast — faster than trust could keep up. Players can't easily tell a serious casino from a fly-by-night one, and "trust me" is not evidence.
CCF's answer is evidence. Casinos put their games to independent test — certified against a published statistical standard, with per-test results made public and a method anyone can re-run. The certificate is the credential; the public register lists the casinos that hold one.
Publicly verifiable
Every certificate has a public record. Anyone — players, affiliates, journalists — can check a casino's certification status in seconds without an account.
Reproducible, not just asserted
Our RNG standard is published in full, and the same test battery runs in your own browser on any sample you give it. "Certified" means something because you can see exactly how the test works.
Independent
CCF is not affiliated with any casino, software provider, or affiliate network, and earns no player-referral commissions.
What CCF Does
A published standard, independently applied
CCF publishes an RNG-certification standard and — through its own testing lab, CCF Labs — certifies casino games against it. The casinos that earn certificates are listed in a public register; there's nothing to simply sign up for.
The Record
Earned by certification
There's no membership to buy. A casino appears here only by having its games certified against CCF-STD-001. Certified casinos are listed in the public directory and may display the CCF Certified mark — standing tied to real, current certificates, not a claim.
- → Listing in the Certified Casinos directory
- → Right to display the CCF Certified mark
- → Subject to the public complaints process
The Credential
RNG & RTP Certification
The substantive credential. A game's random output is statistically tested under the published CCF-STD-001 standard (NIST SP 800-22 battery), and where an RTP audit is ordered, its realized RTP is checked against the declared figure. Each certificate carries a unique ID, a public per-test report, and an embeddable badge that links to the casino's live record.
- → Is this game's RNG actually random?
- → Does the payout match the stated RTP?
- → Is the test method public, so anyone can re-run it?
The Certification Process
How a game is RNG-certified
Certification is evidence-based. Every certificate records the SHA-256 hash of the exact sample tested, and the test method is published so anyone can run it.
Sample
The operator provides a certification-grade sample of raw RNG output from the exact game build to be certified.
Statistical Battery
The sample is run through the CCF-STD-001 battery — the NIST SP 800-22 randomness tests — producing a p-value for each test.
RTP Check
Where an RTP audit is part of the engagement, the game's payout logic is simulated over 10 million+ rounds and the realized RTP is checked against the declared RTP.
Version Lock
The certificate is bound to the specific game build and seeding scheme tested. A material change requires re-certification.
Publish
The per-test report, with exact p-values, is published on a public certificate page. The same battery is open to anyone in our test tool.
Lapse & Revoke
Certificates carry a status. A certificate can lapse or be revoked, and the public record reflects it immediately; the badge links to that record.
Transparency
What CCF is not
Not a government regulator
CCF certification is not a legal gambling license and authorizes operation in no jurisdiction. Casinos remain responsible for their own regulatory licensing in the markets they serve.
Certification is per game
A certificate covers a specific game build, not a whole casino. A certified casino may still run uncertified games — each certificate has its own public record you can look up by its WC- ID in Verify a Certificate, so "certified" always means something specific.
Not a guarantee against loss
A certificate means a game's RNG output passed statistical testing (and, where audited, its RTP matched the declared figure) at the time of testing. Gambling is still gambling: a fair game has a house edge, and you can and will lose money. CCF certifies fairness, not outcomes.
