Nostr Features & Specs

Simple

The protocol is based on very simple & flexibleย eventย objects (which are passed around as plain JSON) and uses standard elliptic-curve cryptography for keys and signing. The only supported transport is websockets connections from clients to relays. This makes it easy to write clients and relays and promotes software diversity.

Resilient

Because Nostr doesn’t rely on a small number of trusted servers for moving or storing data, it’s very resilient. The protocol assumes that relays will disappear and allows users to connect and publish to an arbitrary number of relays that they can change over time.

Verifiable

Because Nostr accounts are based on public-key cryptography it’s easy to verify messages were really sent by the user in question.

Like HTTP or TCP-IP, Nostr is a protocol; an open standard upon which anyone can build. Nostr is not an app or service that you sign up for.
