Bitmessage

Bitmessage is a P2P communications protocol used to send encrypted messages to another person or to many subscribers. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities. It also aims to hide "non-content" data, like the sender and receiver of messages, from eavesdroppers. If Bitmessage is completely new to you, you may wish to start by reading the whitepaper.

Download

An open source client, PyBitmessage, is available for free under the very liberal MIT license.

Download for Windows

If you are looking for someone to message, visit the forum or send me a greeting. Here is my address: BM-BcJFNZDyzQKXCVJZtBJGqoon2f7GKo6s

Security Warning

An active attacker who sends many messages to a particular address in a particular way may be able to determine whether or not the address is owned by a user at that particular Internet connection. Further research is needed. In the mean time, Bitmessage supports using Tor.

Source code

You may view the Python source code on Github. PyBitmessage requires PyQt and OpenSSL. Step-by-step instructions on how to run the source code on Windows is available here.

PyBitmessage should run on any OS though it is only lightly tested on OSX. The start-on-boot and minimize-to-tray features are only implemented for Windows thus far.

Forum

A community-based forum for questions, feedback, and discussion is available at Bitmessage.org/forum.
