Nostr - Notes and Other Stuff Transmitted by Relays

The simplest open protocol that is able to create a censorship-resistant global "social" network once and for all.

It's a very simple idea: each person can publish their notes to multiple relays (which are just simple servers), and people who follow them can connect to these relays and fetch the notes. The protocol just defines the messages that can be sent between clients and relays in order to publish and fetch the content they want.

Relays can also lie about data published by others, but to ensure that isn't a problem, public-key cryptography is used and every note is signed. When you follow someone you're actually following their public key and clients will check notes received from relays to ensure they were properly signed.

The hardest part is how to find in which relay you will find notes of each person you follow, since they can be anywhere.
