We’re excited to announce that MoonDAO, which is focused on creating a self-governing settlement on the Moon, has integrated Chainlink VRF on Ethereum mainnet. In order to select the winners for a Zero-Gravity flight in a transparent manner, we needed access to a tamper-proof and verifiable source of randomness. This marks the second occasion that MoonDAO has used Chainlink VRF, having successfully used the provably fair RNG to select a lucky winner to travel to space. 

MoonDAO is an international collective on a mission to propel humanity into space to explore the cosmos while upholding the Web3 principles of decentralization, inclusivity, and transparency. As part of our mission to increase access and enable people of all backgrounds to participate in this exciting future, in partnership with Space for a Better World, we’re providing the MoonDAO community with a once-in-a-lifetime opportunity to win a Zero-G flight experience.

The winner of this event will join astronauts Doug Hurley and Nicole Stott in zero gravity. The team will fly in parabolic arcs to create a weightless environment where the winner can float, flip, and soar as if they were in outer space. To enter the competition, you must purchase an NFT ticket. 

Chainlink VRF generates both a random number and cryptographic proof off-chain, then delivers both on-chain where the cryptographic proof is verified on-chain prior to the acceptance of the random number by the consuming application. 

The leading verifiable RNG 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 zero-g flight competition 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 helps provide users with automated and publicly verifiable proof directly on-chain that the winner selection process using Chainlink VRF for randomness is provably fair and cannot be tampered with or predicted by the oracle, outside entities, or the MoonDAO team.

About Chainlink
