Nostr is unique in that it has a global public key ID that replicates posts (notes) via relays, so it is scalable, resistant to censorship, and the user fully owns their identity profile. There are only two parts to the network, namely relays and clients, with the Nostr protocol linking them. Every post is signed, and every client validates these signatures.
In this video I explain more about Nostr is, why it is probably one of the easiest networks to get registered and going on, I compare it with some other protocols, and I demonstrate a few of the web as well as Android mobile apps. There are no servers at all needing to be chosen, and it is truly irrelevant which client app is used. I’ll also explain where cryptocurrency may come in, but why you need not worry about it all, or even use it at all.
