Carbon Creatures Integrates Chainlink VRF To Fairly Distribute Rewards to Carbon Negative NFT Holders Connecticut, CT, March 15, 2022


Meta Carbon, the US-based blockchain company helping brands engage their audience on the topic of climate change, has integrated decentralized oracle network Chainlink to support the provably random distribution of rewards for its Carbon Creatures NFT collection.



Determined to enlist more people and corporations to fight the climate crisis, Meta Carbon’s unique NFT collection of 8,888 animal-inspired tokens (minted at CarbonCreatures.com) gives collectors a fun way to reduce their carbon footprint, support social projects, and save endangered creatures from around the world.


“We believe that slowing climate change requires the participation of every person, every corporation every government, and every investor ” says Meta Carbon co-founder, Tom Herman.


“Our vision is to use Web3 technologies to bring financial resources to the front lines of biodiversity loss. To bring transparency to how our individual climate investments create social and environmental impact. By helping brands engage their audience, we can be part of a powerful environmental movement that will make the world a more sustainable place. We’re delighted to be using Chainlink to create something truly amazing that’s not only good for Carbon Creatures collectors but also good for the planet!”


Wear Your Eco-Friendly NFT With Pride

Carbon Creatures NFTs continue to mint on the Polygon blockchain and can be found on NFT platform OpenSea. NFTs include Silverback Gorillas, Bengal Tigers, Black Rhinos, Hawksbill Turtles, Slender Snouted Crocodiles, Brown Monkeys, and the Scimitar Horned Oryx. The next tranche of creatures will include Asian Elephants, Polar Bears, Lemurs, Blue Iguanas, Blue Whales, Great White Sharks, and more. Each NFT animal represents one of these endangered species “frozen in carbonite” and the funds from each sale are invested in carbon projects, carbon offsets, and charities that support endangered animals and the restoration of their habitats. Each Carbon Creature is backed by at least one metric ton of carbon offsets which is the equivalent of an economy class return flight from New York to London.

As well as having a positive social and environmental impact, Meta Carbon’s innovative, eco-friendly NFTs can be named, leveled up, nurtured, traded, and played in a range of specially-built Carbon Creatures and third-party metaverse gaming environments.

Using Chainlink VRF for Secure Randomness


Meta Carbon chose Chainlink Verifiable Random Function (VRF) as a secure and verifiable source of randomness for Carbon Creatures because the industry-leading random number generator (RNG) enables smart contracts to access a verifiably tamper-proof source of randomness on the Polygon blockchain. In this case, Carbon Creatures is using Chainlink VRF to help provide a provably fair random selection for NFT holders, enabling Carbon Creatures to distribute rewards to NFT holders in a fair manner.


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 Carbon Creatures 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 using Chainlink VRF for randomness is provably fair and cannot be tampered with or predicted by the oracle, outside entities, or the Meta Carbon team.


“Meta Carbon is a novel NFT project that helps tackle climate change by giving community members the chance to offset their carbon footprints in a fun and practical way,” says Tomasz Wojewoda, Head of Global Sales at Chainlink Labs.

“Chainlink VRF supports Meta Carbon by helping ensure each animal-inspired Carbon Creature NFT is generated in a provably random process that anyone can verify.”


In addition to using Chainlink VRF, Carbon Creatures will integrate Chainlink Keepers to automatically trigger the gift minting or “airdropping” of NFT assets like Turtle Egg NFTs and Mangrove Seedling NFTs to owners of Carbon Creatures.

“We love the various Chainlink solutions as they enable us to reward our community as it grows with NFT rewards and upgrades when the community hits certain milestones or special events. By using Chainlink, we can leverage time-tested decentralized infrastructure and introduce significant transparency guarantees to our processes,” says Sunita Chaudhary, Meta Carbon’s technical co-founder.


“The ability to access a fair and unbiased source of randomness in a verifiably secure manner enables us to build a whole new set of applications for our NFTs, lucky draws, marketing campaigns, fan rewards, and fair selection across our platform,” she adds.


“Carbon Creatures was developed on the Polygon Network to reduce the emissions typically associated with Ethereum NFT minting by almost 99%,” says Mark David, Meta Carbon’s Chief Strategy Officer. “Some NFTs claim to be carbon neutral, but Carbon Creatures' NFTs are actually hundreds of times carbon-negative meaning that every NFT you buy reduces your carbon footprint rather than increases it!”


As an oracle provider, Chainlink also offers Carbon Creatures the chance to connect actions in the metaverse to their social and environmental impact in the real world, and vice versa.

Carbon Creatures looks forward to using a variety of decentralized Chainlink solutions to enable smart contracts to execute based on real-world events such as releasing funds to Carbon Creatures charities or triggering upgrades in NFTs when the populations of rare animals increase in one of Carbon Creatures’ chosen conservation projects.
