NFTs we’re originally created with the idea of the NFT itself would have utility (ex: the NFT itself is the game license or the TCG card), and not just point to some off-chain asset.

If the NFT isn’t accepted by the intended on-chain contracts then it’s not authentic. In this context ‘authentic’ means that it will be usable for its intended utility, and contracts will identify whether tot hit has utility in their system based on which address created the NFT.

Instead of looking at the creator’s address all the time, incorporating Decentralized Identity can make the process more human-friendly.
