Nostr is a new protocol that allows you to communicate online without fear of censorship, deplatforming, or deboosting.
Platforms like Twitter and Facebook are controlled by a single company, but no one controls the Nostr protocol.
Nostr is similar to email. No one controls the email protocol, and anyone can build a client (like Gmail, Hotmail, etc.) on top of it.
No one controls the Nostr protocol, and anyone can build a client (like Damus, Amethyst, etc.) on top of it.
If you don't like how a certain client works, you can seamlessly move your Nostr account to another client without losing your followers or content.
Bitcoin is built in natively to the Nostr protocol. If you see content you like, you can easily zap bitcoin to someone as a thank you!
On centralized platforms like Twitter and Facebook, the centralized company earns money from your content. But on open protocols like Nostr, you earn money from your content.
