What is Nostr?
Nostr (Notes and Other Stuff Transmitted by Relays) is a simple, open protocol that enables a truly censorship-resistant and global social network.
Unlike traditional social media platforms that are controlled by a single company, Nostr is a decentralized protocol where:
- Your data isn't owned by any single entity
- No central authority can censor or remove your content
- Your identity travels with you across all Nostr clients
- Multiple independent relays ensure redundancy and resilience
How Nostr Works
1. Clients
Apps that let users read and write to the Nostr network
2. Relays
Servers that store and transmit events between clients
3. Public Keys
Your identity on the network, independent of any platform
When you create a Nostr account, you generate a key pair (public and private keys). Your public key is your identity, while your private key (or "nsec") signs your messages cryptographically, proving they came from you.
Messages on Nostr are called "events" and have different "kinds" - from simple text notes (kind 1) to profile metadata (kind 0) to zaps (Lightning Network payments, kind 9735).
Benefits of Nostr
Censorship Resistance
No single entity can silence you or remove your content across all relays.
User Control
You own your identity and can move between clients freely with your key pair.
Innovation Freedom
Developers can build new clients and services without permission.
Global Access
Anyone with internet access can join the network without restrictions.
