Verified Random Chainlink - provides cryptographically secure randomness using a set of Chainlink nodes: they feed data into smart contracts while maintaining the classic consensus mechanism through the committee of these nodes.

By offering Random Number Generation (RNG) for smart contracts, Chainlink VRF helps developers improve interaction by using random results in their blockchain-based applications. Moreover, tamper-proofed randomness with Chainlink VRF cannot be manipulated by any node operator, user, or even attacker, as each oracle in DON has an associated private/public key pair where the private key is maintained off-chain, while while the public key is published on the network.

Many blockchain gaming and non-fungible token (NFT) DApps require a tamper-proof and verifiable random number generation source to enable advanced features such as airdrop, lottery or gambling development.

Chainlink's Verified Random Function (VRF) relies on a decentralized oracle network (DON) to enhance existing blockchains by providing verified off-chain data.
