Welcome to Nostr!
On the surface, it’s a simple tweeter like experience, but decentralized. Your notes are pushed to multiple relays, and you can setup your own relay for peace of mind (back up). You can browse the feed using the client of your liking, Nostr is just a protocol. But…
Under the hood, Nostr is bringing more and more possibilities that will create a new content broadcasting network, long form text, visual, music, videos… with built in payment system. Nostr will soon have all it needs to setup markets of all kind.
What Nostr can become and how it will allow us to communicate with each other and interact with content nobody really knows. It is community developed and everyone is and will contribute their own way.
