# Transparency, Fairness, and Security

The Shikkubo on-chain casino ensures transparency, fairness, and security for all players. By leveraging the power of blockchain technology, the casino eliminates any doubts regarding the integrity of the games and ensures that outcomes are determined based on provably fair algorithms.

In order to ensure transparency and unbiased randomness within the games, we need access to a secure random number generator (RNG) that any user could independently audit. However, RNG solutions for smart contracts require several security considerations to prevent manipulation and ensure system integrity. For instance, RNG solutions derived from blockchain data like block hashes can be exploited by miners/validators, while off-chain RNG solutions derived from off-chain APIs are opaque and don’t provide users with definitive proof of the integrity of the process.

The Shikkubo Casino smart contract will only accept the random number input if it has a valid cryptographic proof, and the cryptographic proof can only be generated if the VRF process is tamper-proof. This provides our users with automated and verifiable assurances directly on-chain that the randomness underlying Shikkubo's games is fair and was not tampered by the oracle, outside entities, or a Shikkubo staff member.
