What is a nostr node?
few understand we have one of the best protocols for efficiently syncing datasets between nostr nodes. nostr officially grows up when NIP-77 lands.
Discussion
a relay or a client with a database
does that mean that some relays don't store any data?
the damus notification relay doesn't store any data
so by my definition of a "nostr node" the damus notification relay technically isn't a nostr node, since there's no way to sync notes between it and yours. maybe nostr node = node that understands nip77 could be one definition.
this could enable nostr to be more like a p2p network in the future with the right overlay network, with nodes syncing with each other via negentropy. me and martti and a few others have been thinking about this.
