# Relays

Tik Tok, X, Facebook, and Instagram all use the old model - a single "relay". With those apps, when you make a post, the post is sent from your phone to the company's "relay". When someone else views your post, their phone downloads your post from the company's "relay". When you follow someone or they follow you, only the company's "relay" knows this. ("Relay" = server)

Nostr uses the new model - one or more relays. With nostr apps, when you make a post, the post is sent from your phone to one or more relays, all owned and controlled by different people. When someone else views your post, their phone downloads the post from anyone of those relays. When you follow someone or they follow you, all your relays and their relays know this.

That's a major difference:

Old = a single company controlled relay/server

Nostr = many independently controlled relays/servers
