Chainlink VRF
Tamper-proof on-chain randomisation
To handle tamper-proof and verifiable randomisation, we integrated Chainlink Verifiable Random Function (VRF) on Polygon Mainnet for the in-game features of "Play & Kollect".
Chainlink VRF will handle the Random Number Generation (RNG) by combining block data that is still unknown when the request is made with the decentralised oracle network node’s pre-committed private key to generate both a random number and a cryptographic proof.
Our 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 you with automated and verifiable assurances directly on-chain that all the randomisation in "Play & Kollect" is provably fair and was not tampered with by any third party like the CyberKongz Team, the oracle or other outside entities. So for instance, if someone finds a rare NFT on their adventure run, everyone can relate to the fact that they truly deserve it.
Chainlink VRF brings absolute transparency as RNG for "Play & Kollect".
