Shared Private Data
NorthStar Social: People. Privacy. Period.
NorthStar Social is where your public and private social networks converge. The world's first decentralized local-first social network to keep you in control of your data. Your privacy is too precious to leave in the hands of corporations and billionaires who don’t have your best interests in mind. Privacy is built-in. Your public and personal social connections in one app.

And more importantly, how do we keep bad actors from simply pulling their data straight from a relay?

A Cypherpunk's Manifesto
Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn't want the whole world to know, but a secret matter is something one doesn't want anybody to know. Privacy is the power to selectively reveal oneself to the world.

In 2026, @bsky.app is focused on what’s next for open social: bringing together users for conversations around live events, creator and platform monetization, and private state, giving users truly private data while preserving ownership and portability at the protocol level.
