One of the best descriptions I’ve seen. No fluff, no technical jargon. Why Jack left X and Bluesky, was because he wanted a social platform that was also going to be censorship free. The Nostr design depends on numerous hosted relays, and there is/are no central server/s that store posts. Nostr is quite different from the decentralised type hosting of Bluesky or Fediverse servers.
I’m glad too he touched on Nostr not working on top of blockchain, because although there are many who punt crypto on Nostr, and you can tip any poster in crypto if you wish for their post, you firstly do not have to use any of that (it is optional) and the network does not rest on top of it. Many users on Nostr (like myself) don’t mention crypto and post about perfectly normal things.
