VRF Randomness

We believe that the most basic requirement for a raffle is to be fair and impartial, so we strive to make all Raffllrrs raffles provably fair. Being provably fair means that you don't have to trust that our games are fair, we can prove they are and you can verify it, which aligns with the blockchain mantra "don't trust, verify".
​Chainlink VRF is the industry-standard source for provably fair, verifiable, and tamper-proof on-chain randomness. Chainlink VRF generates both a random number and cryptographic proof, then delivers both on-chain where the cryptographic proof is verified prior to the acceptance of the random number by the consuming application.
Raffllrr uses Chainlink VRF (Verifiable Random Function). It is a provably fair and verifiable random number generator (RNG) that enables smart contracts to access random values without compromising security or usability to select raffle winners.
