Briar Mailbox This project aims to develop an easy way for Briar users to increase their reachability and lower the battery drain of their phone. In Briar messages are exchanged directly between contacts (peer-to-peer). This kind of synchronous message exchange requires contacts to be online and connected to each other. While this is great for privacy (no central server which can log things or be censored) it's bad for reachability, especially in mobile networks where connectivity can be limited.
