Nostr (Notes and Other Stuff Transmitted by Relays) is an open, simple protocol for building a censorship-resistant global social network. Users sign notes with cryptographic keys and publish them to independently operated relays, with no central trusted server.

Use cases

• build a censorship-resistant social network
• post short notes without a central platform
• self-host a relay server for social content
• follow people by public key across relays
• implement a Nostr client or relay from the NIP specs

When to choose

• you want decentralized, tamperproof social publishing without P2P complexity
• you need an open protocol with many independent clients and relays
• you want identity based on cryptographic keys rather than platform accounts

When to avoid

• you need a turnkey social app with moderation and rich features out of the box
• you require guaranteed content availability, since relays are voluntary and may drop data
• you need strong privacy, as notes are public and signed by design
