"Every new contact list that gets published overwrites the past ones, so it should contain all entries. Relays and clients SHOULD delete past contact lists as soon as they receive a new one.”

Nostr is an event system. It would be useful to have a state management system on top of it, so changes are merged instead of overwriting.

I think it would be powerful to combine gundb with nostr for that purpose. I originally built iris.to on gundb and I’m now adding nostr.
