🔐 Transparency and Security

JellyBet smart contract communicates with an off-chain service powered by Chainlink which ensures the randomness of the results and prevents the system from being exploited and hacked.

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 JellyBet 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 JellyBet’s games is provably fair and was not tampered by the oracle, outside entities, or a JellyBet staff member.
