 Briar: Encrypted Private Social, Forums,
 and Messaging with no Central Server

 https://briarproject.org/how-it-works/

 Exchange data over Tor, WiFi, Bluetooth.
 Run a digital dead drop without Internet.

 Briar is a messaging app designed for activists,
 journalists, and anyone else who needs a safe, easy and
 robust way to communicate. Unlike traditional messaging
 apps, Briar doesn’t rely on a central server – messages
 are synchronized directly between the users’ devices. If
 the Internet’s down, Briar can sync via Bluetooth, Wi-Fi
 or memory cards, keeping the information flowing in a
 crisis. If the Internet’s up, Briar can sync via the Tor
 network, protecting users and their relationships from
 surveillance.

 Briar provides private messaging, public forums and blogs
 that are protected against the following surveillance and
 censorship threats:

 Metadata surveillance. Briar uses the Tor network to
 prevent eavesdroppers from learning which users are
 talking to each other. Each user’s contact list is
 encrypted and stored on her own device.

 Content surveillance. All communication between devices
 is encrypted end-to-end, protecting the content from
 eavesdropping or tampering.

 Content filtering. Briar’s end-to-end encryption prevents
 keyword filtering, and because of its decentralized design
 there are no servers to block.

 Takedown orders. Every user who subscribes to a forum keeps
 a copy of its content, so there’s no single point where a
 post can be deleted.

 Denial of service attacks. Briar’s forums have no central
 server to attack, and every subscriber has access to the
 content even if they’re offline.

 Internet blackouts. Briar can operate over Bluetooth and
 Wi-Fi to keep information flowing during blackouts.
