What Is Nostr

Nostr is a decentralised communication protocol. Not a company, not a platform — a set of rules, like Bitcoin, that anyone can build on.

The name stands for Notes and Other Stuff Transmitted by Relays. It’s a protocol for publishing and reading content without a central authority controlling what’s allowed, who can speak, or what can be seen.

Here’s how it works in simple terms.

Everyone on Nostr has a keypair — a private key and a public key, similar to Bitcoin. Your public key is your identity. Your private key lets you sign your posts. You own your identity in the same way you own your Bitcoin — through cryptographic keys that no company can take from you.

Posts are broadcast to relays — servers that store and distribute content. Anyone can run a relay. Multiple relays mean no single point of censorship or failure. If one relay removes your content, others still carry it.

Nostr clients — apps that let you read and write on the protocol — can be built by anyone. The protocol is open. The data is yours.

The connection to Lightning is natural and deep. Both use keypairs for identity. Both are permissionless networks. Both prioritise censorship resistance and individual sovereignty. Zaps — Lightning payments sent as reactions — integrate directly into Nostr clients.

Nostr is still early and imperfect. The user experience doesn’t match Twitter or Instagram. The content ecosystem is smaller. But it’s growing — and it’s growing among the people most interested in uncensorable communication and direct monetisation.

For Bitcoin holders who care about why Bitcoin was built, Nostr feels like a natural companion. Same principles. Different domain.

Tomorrow: Bitcoin and the creator economy — getting paid in sats.
