Project: Distributed, trustless, anonymous, encrypted, messenger/mailer with the goal of hiding senders and receivers of messages. Also can't be brought down since it is distributed. Problem: Limited time to work on it. I have a working prototype with one-to-one, one-to-many, and many-to-many messaging/mailing working fully encrypted over ipv4. Building out the transport methods is the next main task (ipv4 works, need ipv6/tor/i2p/file/qr/etc).

I'm curious about your cryptographic schema. Are you using encryption-by-proxy to hide the sender/receiver? How are you making them anonymous?

  Elliptical curve asymmetrical keys for the actual encryption. No encryption by proxy by default. Basically think of a shared database where you don't know who inserts data or who selects data. Making all payloads the same size, and constantly transmitting/receiving at a set rate ensures that even your isp can't tell if you are the sender or receiver of a message. The security/anonymity levels are adjustable so you don't have to use the features if you'd rather not. Also with shared asymetrical keys, users can communicate without having to sign/identify themselves within the message. This also provides plausible deniability. There are a lot more layers, but I'll keep it brief here.

  Kind of, but more anonymous and not tied to tor. More like Bitmessage (https://bitmessage.org https://bitmessage.org) but with a fresh approach. You can connect via tor (tor-tor) and talk to people on i2p, or clearnet, sneakernet, etc.

    Sounds really interesting. Would you mind shooting me an email at aakil at safezero dot org?

You might find Ethereum's Whisper messaging protocol interesting. https://github.com/ethereum/wiki/wiki/Whisper https://github.com/ethereum/wiki/wiki/Whisper
