Idunno, this is pretty interesting. In the Bitcoin op_return data, is a link to this website. I checked it out, and people are using Json scripts in inscriptions to to emulate Ethereum's ERC-20 (tokens) and ERC-721(NFTs). Called BRC-20s and BRC-721. I mean, it's shitcoiny, yes. But goes to show everything you can do elsewhere, you can also do on Bitcoin.
