Anyone can run a relay. A relay is very simple and dumb. It does nothing besides accepting posts from some people and forwarding to others. Relays don’t have to be trusted. Signatures are verified on the client side.

When you open your nostr client, you will see all the notes posted by you and those you follow in chronological order.

There are no algorithms deciding what to show you, what to withhold from you, or censoring your posts.

Like Bitcoin, nostr uses public/private key pairs.

PUBLIC KEY = npub, like a username

PRIVATE KEY = nsec, like a password

In both of the above examples, one could postulate that Satoshi was using numbers to indicate a reversal, an unwinding of the damage inflicted by government overreach.
