Outbox/Inbox is where clients connect to authors relays directly to fetch content, in Inbox model you write reactions/dms/replies etc to the recipients read relays, this allows the recipient to see your interactions even if you dont have relays in common.

The point of this is to reward people for using clients that support Outbox/Inbox model, i think all clients should have added support for this by now. 

 Is there a NIP for this? 

 @jb55 kinda seems like #damus doesn’t support this? Do we have a ticket for it? cc/ @elsat 

 not yet but once we switch to nostrdb for everything we should. 

 Is Amethyst such a client? No zap when boosted.  

 Not sure about that client. But you probably need to add a lightning address in your #nostr profile. 

 is there a NIP for this? I want to read more about it and understand the whole heated debate that is going on rn
