We have previously covered Tor which is perhaps the most popular decentralized overlay anonymity network (DarkNet) in the world.
Today we’ll cover I2P, which is a decentralized overlay network much like Tor in many ways. But with more features built into it.
From I2P site:
I2P is an anonymous overlay network – a network within a network. It is intended to protect communication from dragnet surveillance and monitoring by third parties such as ISPs.
I2P is used by many people who care about their privacy: activists, oppressed people, journalists and whistleblowers, as well as the average person.
I2P offers features like blogging, forums, email, anonymous sites and more. It is a younger project than Tor but has many promising advances and features when compared. It is a great addition to your privacy arsenal.
