Nostr is a way to share information around the world without anyone being able to stop it. It helps make social networks better. Instead of having one person in charge, everyone who uses Nostr can have a copy.
A direct integration with Bitcoin and the Lightning Network makes it decentralized social and decentralized value.
Here is a list of great open-source Nostr resources on GitHub.
