I2P is a decentralized privacy overlay network, much like Tor, except it is much better suited for use by P2P and Torrent apps.
DarkMX is now capable of making user to user connections over I2P, using an external I2P client of your choice. This feature can be activated from Settings > I2P.
You can download a fairly simple I2P client called i2pd. It's website is
https://i2pd.website/. We don't have anything to do with it's development, so do your own due diligence before installing it. The original I2P client (Java-based) is available from
https://geti2p.net/en/. There are also other clients available, easily findable using any search engine.
DarkMX connects to your local I2P client over the local loopback 127.0.0.1 interface using the I2CP protocol, which is a low-level message based protocol. DarkMX has implemented its own streaming layer on top of I2CP.
IMPORTANT If you use the I2PD non-java client, you must enable the I2CP protocol by running it with
--i2cp.enabled 1
