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).
