NIP-01

Basic protocol flow

NIP-01 is the foundation that makes Nostr work. It explains the basic shape of a Nostr message, called an event, and how apps send those events to relays so other people can read them. If Nostr were a postal system, this NIP would describe what an envelope looks like, how it is signed, and how post offices should accept and deliver it.

For a normal user, this is the reason your notes, replies, follows, and other activity can move between different Nostr apps. The apps may look different, but they agree on this basic format, so your identity and content are not trapped inside one company's database.
