Just came up with a new plan for fixing replaceable events with @npub12262q... The biggest issue with replaceable events (contact lists, profiles, lists,) is that there is no versioning scheme. This leads to many issues where your contact list is dropped, comments+likes+zaps appearing only on older versions of a post, etc. We need a concept of versioned events in nostr and a way of querying those effectively. Looking forward to working with @npub12262q... on this and implementing it in Damus, nostrdb and hopefully strfry once we figure it all out.
