First, thank you 😊

It touches on both, depending on the service you plug it into. I’ll try to describe what I mean. 

The handle or global namespace is the satoshi name, for instance the satoshi with ord number 1953186218210489 has a name of ‘aaaaaaaaaaa’.

For nostr, you could save the sat name to your profile and after anyone plugging that satoshi name into search could retrieve all history of all pubkeys contained in the inscriptions of that satoshi and it would all be your content.   There are also ways to make sure your pubkeys aren’t appropriated by others.

I can also imagine a service that would handle websites. Dns basically does cert and ip lookup. If you extend the inscription and provide the ip address beside the pubkey, which can be used to verify that the server holds the private key, I can imagine a legit request can be made to get the website data. 

Does that make sense?
