NOSTR (Notes and Other Stuff Transmitted by Relays) is a protocol not a platform or single app. It operates by individuals running a Relay, which anyone can do. Then you or anyone else , can use any app or website client to connect to that Relay and transmit notes and other stuff. No one entity or person controls the network. Free your speech.
