Twitter founder Jack Dorsey pumps $10 million into a nonprofit to build Nostr-based social media apps (techcrunch.com)

Having fucked up social discourse with Twitter and then Bluesky, Jack Dorsey claims he has seen the error of his ways, and definitely won't do it a third time with his new nonprofit aimed at helping developers build and deploy (OSS or commercial) social media tech built on the Nostr platform (with AI!). Yeesh, I might be biased. Maybe I shouldn't be writing these summaries.

What are the differences between Nostr, AT Protocol and ActivityPub?

[โ€“] artifex@piefed.social 11 points 20 hours ago* (last edited 19 hours ago)

I think the main one is that Nostr is supposed to be really simple, and derive some security/privacy from that simplicity. Whereas ATProto and ActivityPub store and forward content so that each rely has a copy, on Nostr nodes the messages are all ephemeral. So it has something of a following with crypto bros and privacy enthusiasts. With nostr IDs are also based on public/private keys unlike ATProto/ActivityPub that use a username@instancename scheme, so signing and identifying content that belongs to a user is easier and more guaranteed to be correct, and your username isn't tied to any specific server "instance"
