Every bet is locked with cryptographic certainty
We secure each result using independent seeds and cryptographic hashing. The outcome is tamper-proof and transparently verifiable by anyone. This ensures game integrity without relying on third parties.
How we ensure
all bets are secure
all bets are secure
Verifiable uses a combination of client seed, server seed, and nonce to generate outcomes that can be independently verified. Each value is hashed before use and revealed after the game, so operators can't manipulate results and players can check fairness instantly.
Seed Generation
Server and client seeds are created before the game starts.
Result Calculation
Seeds and nonce are combined to generate a fair and deterministic result.
Verification
Signed proof is revealed so results can be independently verified.
How we ensure all games are secure
At Verifiable.bet, we implement proven cryptographic standards to ensure every game outcome is fair and can be independently verified. Our approach combines battle-tested technology with complete transparency, giving you confidence that every play is handled fairly.
How it works
Our system uses a combination of three elements to create a unique string and verifiable randomness: a client seed that you can change before each game, a server seed that identifies your gaming session, and a nonce that ensures each play is unique. Before you make a play, you'll receive your server seed and have the option to provide your own client seed for additional randomness. The system then generates a unique but predictable incrementing nonce for each play.
When you make a play, our system combines these elements to create an input that's signed with our private key to generate the game outcome. The proof of this signature is stored securely and revealed after the game. This proof, combined with our public key, allows anyone to independently verify that the game was fair and the outcome was determined honestly.

Why our system is better
Traditional online casinos rely on internal random number generators that players can't verify or simple syymetric hashing functions. When an internal random number generator is used, this creates a fundamental trust issue - players must simply believe that the casino is being honest. And symmetric hashing functions whilst secure still have known outcomes to the casino before you press the play button. Our system eliminates this problem by making every game a blind and mathematically verifiable outcome.
The beauty of our system is that it doesn't require trust in third-party auditors or certifications knowing how the casino treats the randomness. Instead, fairness is built directly into the technology. Every player has the power to verify results themselves at any time, and the result isn't known to the operator until after the game is played creating a level of transparency that's unprecedented in online gaming.
Unlike other fair systems that require revealing server seeds and resetting nonces, our system maintains continuous playability while still providing complete verifiability. This means you can keep playing with the same seed for as long as you want, without any interruptions to your gaming experience.

Technical excellence
Our system is built on the ECVRF-SECP256K1-SHA256-TAI algorithm, an open standard specified in RFC 9381 by the Internet Research Task Force. This choice of technology means our system has been thoroughly reviewed by security experts and is built on battle-tested, widely trusted cryptographic principles. The open nature of the standard means any developer can implement their own verification tools, further enhancing transparency.
The same technology is used by the crypto community to generate random numbers for lotteries, raffles. Blockchains use it to perform fair leader elections. Some blockchains have even included native support for smart contracts to generate and prove randomness.

Building trust through security
While the underlying technology provides strong security, we've added additional layers to ensure complete trust. Our servers are completely isolated from operators, who never have access to the private keys used in the verification process. Every outcome is timestamped and stored publicly, creating an immutable record of all games. Our system has been independently audited and certified, providing additional assurance of its integrity.
What sets us apart is that we're an independent provider ourselves, completely separate from the operators. This separation ensures that operators have no access to the private keys or any ability to influence outcomes. The outcomes are never revealed to operators until after the game is played and a publicly accessible record is created, complete with timestamps of when each outcome was generated.

Verifying results made simple
We believe in making verification accessible to everyone. You can verify game results using our open-source verifier, our public API, or by implementing your own verification using our open standards. No matter which method you choose, you'll get the same result - complete confidence that every game is fair.
Our commitment to transparency and verifiability isn't just a feature - it's the foundation of everything we do. We're proud to offer a system where fairness isn't just promised, it's mathematically proven.
