Nostr is a simple, open protocol that enables a truly censorship-resistant global social network.

How it works

Every user has a keypair. Events are signed and broadcast to relays. Relays store and forward events — they are the backbone of the network.

Key concepts

• Events: The atomic unit of data. Everything is an event: posts, reactions, profile updates.
• Relays: Servers that store and forward events. Users choose which relays to use.
• NIPs: Nostr Implementation Possibilities — the spec documents that define the protocol.

Why it matters

No single entity controls the network. Your identity is your keypair, portable across clients and relays.
