I2P: End-to-end encrypted and anonymous internet
I really like I2P as a project, and I think it gets a lot of things right. For example having every network participant relay some internal traffic, instead of relying on altruism from relay operators, makes it much harder for a single entity to control enough hops to deanonymize users.Sadly, outside of torrenting I2P doesn't seem to have much traction, losing out to the better funded tor project
