An NFT collection based on a funding model designed by Vitalik Buterin and others is gaining popularity on Opensea. The collection is called Quadratic Funding.
An NFT collection seemingly associated with Ethereum co-founder Vitalik Buterin has begun skyrocketing in value on OpenSea. The Quadratic Funding Open Edition is a collection that celebrates the quadratic funding proposal that Buterin, Harvard economist Zoë Hitzig, and RadicalxChange founder Glen Weyl published in 2018.

The collection contains various on-chain records of the proposal. This includes a new digital copy of the whitepaper signed by the three authors and two essays by Gitcoin’s co-founders celebrating its impact.
