Isn’t this where https://pears.com wins? Why can’t it be incorporated into NOSTR to reduce dependency on relays? Everyone becomes a relay.
relay goes bye bye when you turn off phone lol
How long you have the phone off during its life time? 0,1%?
Also if you understand how hole-punch / pears works then you’d realise it’s not an issue.
It totally should be. But I think Nostr devs don’t see the issue.
