I’m sure it’s possible to build a similar platform with a central database handling transactions and Stripe payouts, but I’m not sure it would be met with the same enthusiasm (and, despite the possibility of this with past tech, no pre-blockchain digital art marketplace has come close to meeting it in sales).
Due to the decentralization of the art tokens (via the blockchain), the community has been able to grow and evolve in a way that a centralized platform could not. For example: while the site’s contract was paused to repair a bug, artists continued to trade tokens directly peer-to-peer (no platform needed), and even build new sites and platforms that enabled trading & auctioning on the same Hicetnunc-minted tokens.
