Generative vs Non-Generative NFT Marketplaces
Erick Calderon, CEO of Art Blocks, on the evolution of NFT marketplaces
The distinction is really about when the artwork comes into existence and who mints it. On a generative platform like Art Blocks, the artist uploads code, not a finished image, then the collector mints and the final output is created at purchase. On a non generative platform like Foundation, the creator uploads a finished file, mints it into their own collection, then chooses how and when to list it for sale.

This changes the artist workflow. Art Blocks is built for artists who can write or work from an algorithm that can produce many distinct outputs from one script. Foundation starts with a finished asset file, hosted on IPFS, then wraps that file in an NFT the creator owns before sale.

It also changes the collector experience. Art Blocks treats the mint itself as the creative moment, because token data and the on chain script combine to render the piece. OpenSea and Foundation mostly act as venues where already minted NFTs are displayed, listed, and traded, with creator earnings layered on after the asset exists.

That is why specialized marketplaces matter. General marketplaces are good at cataloging and trading many NFT types, but dedicated art venues win when the medium needs custom storefronts, live rendering, curation, or creator specific sales mechanics. Art Blocks and Nifty Gateway both fit that specialist pattern, though they focus on different kinds of art objects.
The next step is more infrastructure splitting by medium. Generative art platforms will keep building minting, rendering, and curation tools around code based works, while broader marketplaces stay strongest as secondary liquidity hubs. That pushes the NFT market toward a structure closer to the traditional art world, where specialist venues shape creation and general venues aggregate trading.
