LooksRare Integrates Chainlink VRF to Help Power YOLO

YOLO: backed by transparent, verifiable randomness.

Been enjoying YOLO?

Our thrilling new game — just like Raffles — is powered by everyone’s favorite source of randomness: Chainlink’s Verifiable Random Function, or VRF.

By integrating the industry-leading decentralized oracle network, we can ensure every YOLO round remains exciting, transparent, and fair for users like you.

Chainlink VRF gives us access to a tamper-proof and auditable source of randomness. It’s what we use to determine the winner for each round of YOLO.

Fundamentally, it can cryptographically prove to the world that every round is 100% fair and unbiased.

Win big with YOLO.

❓Why Not Use Another Source?

A random number generator (RNG) is vital for picking winners fairly. If YOLO happened behind closed doors, an off-chain one could easily fit the use case.

But it doesn’t. So, we needed a solution that could:

👉 Prevent manipulation

👉 Maintain data integrity

👉 Ensure transparency

Something like a block hash could be used to generate random numbers, but miners and validators can exploit this system. Not good enough for us.

We landed on Chainlink VRF because it’s verifiably tamper-proof, giving users definitive proof that YOLO rounds fairly and unbiasedly select winners. Combined with its generation and on-chain verification of cryptographic proofs, Chainlink VRF ensures integrity in every random number supplied to the YOLO contracts.

⚙️ How It Works

Chainlink VRF works by combining block data that is still unknown when the request is made with the oracle node's pre-committed private key to generate both a random number and a cryptographic proof.

The YOLO contract only accepts the random number input if the cryptographic proof is provided, and that proof can only be generated if the VRF process is tamper-proof.

Proving to you (and everyone else!) that the winner selection process wasn’t messed with by the oracle, any outside entities, or the LooksRare team.

How Chainlink works.

“Technologies like Chainlink’s VRF are the cornerstone of an exciting new wave of provably fair, on-chain games,” said Guts, Co-founder of LooksRare. “It’s not just easy to integrate — it provides us with the gold standard of transparent, cryptographic proof that YOLO rounds are truly unpredictable.”
