Today's #nostr idea:

Notification-only relays

If we think about the ultimate decentralized version of Nostr, it would be that everyone runs their own relay to host their own notes.

That would pose a scaling issue, because if you follow 1000 npubs, you have to check 1000 relays to stay up to date.

What if we had some shared relays (notification-only relays), containing only notifications that an npub has posted something, but not the content. So it's just a signal that if you are following them you should go get the new stuff from their personal relay. Running such a notification-only shared relay would have a much lower liability than running a "full" shared relay, because you don't host actual content, and you would also have reduced storage requirements because no content.

Apologies if this is a dumb idea, just throwing this out there
