I2P Comments

Project is under active development, and appears to be reputable.

Positive Comment by fuzzee
about I2P and Tor Browser 15 days ago

As far as I'm aware, this anonymous overlay network has recieved few if any audits from a reputable source. They're slow but meticulous in their development cycles. Such a system isn't as easy to configure as something like the Tor Browser, but is just as easy to initially setup. I recommend for scholars, developers wishing to help, and those who are just curious. (Side note: This project has been bundled into TAILS, or The Amnesic Incognito Live System, which likely warrents some inherent value to the privacy and anonymity people can achieve with this service/program.) I may release a full fledged review in the future.
