NFTs rely on the cryptographic security of public blockchain networks for properties like traceable provenance and ownership. This is what gives us the ability to "own" digital data, and by extension, gives them value.
When it comes to AI generated art, however, the full extent of the provenance paradigm is currently unfulfilled. Until zkMon, AI art had to be created fully off-chain, then brought on-chain manually — despite the art generation process being digitally native. This means that, until now, outputs generated from an AI artist could never have been cryptographically linked to that original art model.
