OMNI.ai is proud to announce that we have integrated Chainlink VRF (Verifiable Randomness Function) to empower our Celebrity NFT Drops and the In-App Giveaways System. Chainlink VRF is a secure and auditable random number generator (RNG) that enables smart contracts to access a source of randomness that is provably fair and tamper-proof.

Through Chainlink VRF, OMNI now has a transparent and unbiased source of randomness for our Celebrity NFT Drops, 2,000 NFTs collectible art representing some of the top 100 most celebrated, legendary artists, cultural icons, and sporting heroes. Chainlink VRF will be used to select random participants in the Omni Strong Holder program — those who hold at least 5000 OMNI tokens — to receive one of these rare Celebrity NFTs.

Additionally, OMNI will use Chainlink VRF to randomly select posts and/or comments to empower creators’ sponsored giveaways and promos inside the app. This will bring a much-needed layer of transparency to the Giveaways taking place inside Social Media Posts.

We ultimately selected Chainlink for RNG because it is one of the oldest and best-known decentralized oracle networks, helping secure tens of billions in value for applications throughout DeFi, blockchain gaming, and NFTs. Chainlink VRF uses secure off-chain computation to provide users with full transparency into the integrity of each random number provided and has already supported major NFT drops such as the Bored Ape Yacht Club.

How does Chainlink VRF work in OMNI?

OMNI wrote a simple smart contract to use Chainlink VRF. Our participants will be on a list ordered by the wallet address. Each wallet will be assigned an index starting from 0. Ex: 200 participants will be indexed from 0 to 199.

The round winner will be picked by applying a math modulus between the random number and the number of participants. The result will be the index of the winner.

For Example:

  • random number (RA) = 123456789
  • total participants (TA) = 200
  • index = RA mod TA = 189
  • Therefore the wallet on index 189 is the winner

In the future, we plan to continue leveraging Chainlink VRF to access a secure, verifiable, and transparent source of randomness to help power fair giveaways, promotions, competitions, and more.
