Chainlink News and Announcements
Congratulations to the Chainlink Fall 2021 Hackathon winners!
These standout projects are pushing smart contract innovation forward for DeFi, NFTs, & beyond.
Thank you to all the judges, sponsors, & participants who made this hackathon a huge success.
In a new article in @Entrepreneur, @ChainlinkLabs CMO @adelynzhou dives into how blockchains and oracles are redefining the insurance industry.
Here are 4 industry shifts to watch and the innovative projects making blockchain-based coverage a reality.
@Gartner_inc’s latest report on smart contract security highlights the importance of tamper-resistant oracle networks, including an analysis of how Chainlink provides secure data feeds, off-chain computation, and a blockchain middleware for enterprises.
Blockchain projects need a tamper-proof source of randomness to power an array of use cases:
-Secure NFT minting
-Dynamic in-game outcomes
-Fair giveaways
-And much more
See how top dApps use Chainlink VRF to create verifiably fair player experiences.
Chainlink Grants
Testing infrastructure enables developers to ensure their dApps perform in all conditions.

-1 40-acre parcel of land
-950 NFTs representing plots
-1000s of DAO Citizens
@CityDao needed a way to fairly raffle its land NFTs to Citizens.
Chainlink VRF was the perfect solution, providing a verifiably random way to select winners.
A commitment to fairness and transparency is vital for inspiring community confidence.
Explore how @WenLamboDeFi uses Chainlink VRF to help fairly select winners in community drawings, with any user able to independently verify the results.
Verifiable RNG brings more transparency to NFT projects.
@DigiBudz is using Chainlink VRF to help ensure its minting process is fair and to pick airdrop and rewards recipients randomly and transparently.
Blockchain games can benefit from randomization in a number of ways.
@BornSoldiersNFT is using Chainlink VRF to randomly distribute NFTs with several further use cases to follow, helping make their NFT game on @0xPolygon more exciting and fair.
Chainlink VRF is tamper-proof, meaning the oracle cannot manipulate the random number output.
@Decentra_Lotto is using Chainlink VRF to prove that the random numbers used to pick winners in its raffles are unbiased and manipulation-resistant.
Blockchain games can benefit from both verifiable randomness and reliable automation.
@d_skyscraper is using Chainlink VRF to support chance-based mechanics and Keepers to automatically fund VRF requests in its NFT real estate game.
On-chain generative art and verifiable RNG can be a powerful combination.
Creators on the @Nil__dao platform can now use Chainlink VRF to enhance their generative work with unpredictable randomness—with collectors able to verify its integrity.
@MinecryptoMC, a play-to-earn server in Minecraft, is using Chainlink VRF to assign verifiably random purity ranks to in-game NFTs.
@DirtybirdArt is launching a new NFT drop designed by @birdcapstuff and inspired by @VonStroke.
Chainlink VRF is supporting the drop by helping randomly assign a set of traits to each NFT and unbiasedly selecting winners in community giveaways.
Offering simplicity to users can help an NFT marketplace stand out.
