the basic architecture of Nostr is basically what i've been saying that ActivityPub should have been - but ActivityPub was designed by a W3C workgroup, so of course it had to centre around existing web standards to even get accepted

i've basically been complaining for years about how ActivityPub chose to solve the identity problem. i've been on Mastodon since 2017 - a year after it was released - and the lack of nomadic identities was always a pet peeve of mine
should nostr adopt some things from ap?
i think there are a couple of things but i'd have to think about it. a big one that was recently implemented across many servers was editing. when you edit a post, others can see that it was edited and you can check the edit history if you want. also, if you repost something and it gets edited, you get a notification about it, so you can check if you still approve of what you reposted. but you can't withdraw anything on Nostr. you can't undo a like or a repost.
