Unstoppabledomains.com is selling NFT domains. Once you purchase a domain from them, you have to mint it. If you don’t mint it, they say that the domain name is still yours but you haven’t proven the ownership by minting it on the blockchain. What’s stopping someone else from just minting domain names that are purchased by someone else on unstoppabledomains? And what exactly are they doing that prevents someone else from selling NFT domains with their own extensions? And what prevents me from minting random domain names on Ethereum blockchain? After all unstoppabledomains is not a central authority.
