An ex. of how some things are functioning in the web3 space right now: alignment on the prod dev approach “almost all name service providers are including Nfts and same approach for registration and metadata”,

On the other hand have anyone noticed that we have .Bitcoin names by two different providers UD & Stacks, from a user perspective I have to check which provider is integrated by the apps am using, Not very optimal, isn’t ?
