Vector Field Integrates Chainlink VRF to Deliver Secure Randomness for On-Chain Materiality in NFTs

The designer Joey Roth has spent his decade-long career creating objects like teapots, speaker systems, planters, and coffee devices. Materials—usually a combination of wood, metal, and ceramic—have always been the starting point and anchor for his projects. His designs have always been physical because of the dialogue that occurs between designer and material.

While much of Roth’s process has always been digital, from CAD modeling and parts analysis to 3D printing to AR demos for prospective collectors, it always played a supporting role to the physical products themselves. That’s because digital design always lacked the materiality, the combination of patina, randomness, and scarcity, that comprised the conceptual core of Roth’s designs.



With the help of Chainlink's industry-leading oracle network, there now exists the possibility of connecting blockchain-based art to physical-world phenomena. Combined with blockchain’s scarcity and provenance mechanics, Roth and his team are now working with a fundamentally new design material—one that combines the speed and flexibility of the digital with the materiality and rarity of the physical.

Vector Field is an NFT project exploring blockchain as a material, the physicality of randomness, and immutable minimalism. Each of the 300 Vector Field NFTs is generated and stored completely on-chain. That means that rather than containing a link to an image file the instructions to draw each Field are encoded within the token itself.

Blockchains are deterministic, but the physical world is not. To give materiality to the digital world, we needed a tamper-proof source of on-chain randomness. We use Chainlink VRF as a secure random number generator to help bring transparent randomness to Vector Field.

Randomness is a definitive property of physical materials. No matter how well understood from an engineering perspective, a good design needs to account for its unique properties, and especially for inevitable variations. While this is a challenge, negotiating the tension between the materials’ physicality and the design intention has formed the basis of Roth’s practice. The pushback from physical materials leads to better design outcomes than would be possible with hypothetically fully compliant materials. Digital was fully compliant, and thus poorly suited to Roth’s process, until the integration of Chainlink VRF.

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 Vector Field 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 cannot be tampered with or predicted by the oracle, outside entities, or the Vector Field team.


With Chainlink VRF, Vector Field will be able to deliver on its core mission to:

  • Generate art that’s built on the physicality of randomness
  • Use collector community behavioral data along with randomness to drive a dynamic NFT art series
  • Convert collectors into trustees who will guide all steps after art-making with smart contract-aligned incentives

The injection of real-world data that’s captured on-chain at the time of mint or beyond makes digital artwork just artwork, with the collector value and scarcity more than a social construct.

The Vector Field contract uses Chainlink VRF, which is an oracle that allows entropy to be called into smart contract functions.

Like physical objects, each Vector Field exists between the artist’s intention and the material’s natural randomness. Through this process, we are using the blockchain itself as a material, imbuing it with randomness that would not normally exist without our intervention.The final Vector Field forms are a record of the dialogue between the smart contract and a random number generated from quantum phenomena.

Chainlink VRF is the best and most secure way to inject randomness into a Solidity smart contract. Combined with provenance and scarcity, this completes the blockchain’s potential for digital materiality.

Although it was the only solution that provided randomness as an easy-to-call Solidity function,  Chainlink’s excellent documentation, developer community, and its extensive suite of decentralized services made our decision to integrate easy.

Chainlink VRF’s verifiable randomness is foundational to the Vector Field concept of blockchain-as-material. Decentralization of other oracles is critical for our dynamic NFT work that’s building on the original Vector Field, currently in progress.

If Vector Field were built on insecure randomness, the visuals would be similar but the meaning, impact, and value of the work would be compromised. Secure, provable randomness is the piece’s connection to the physical world. Other Chainlink oracles will be used in a similar way for near-future dynamic NFT work.

“Chainlink VRF was the missing piece that makes the blockchain a truly expressive material for art and design. Having successfully integrated with Chainlink for the Vector Field launch and mainnet deployment, we’re already working on projects that use Chainlink Keepers and other data source oracles to further extend the connection between digital and physical and bridge materiality in art.”

Just as currency is an encasement of value—goods, hours of work, etc; art is an encasement of an idea or concept at a moment in time.

Vector Field is live now, and some of our Discord community have already started minting NFTs. Check out the following links for more information:
