Last updated: February 16, 2017


i2pd (I2P Daemon) is a full-featured C++ implementation of I2P client.

I2P (Invisible Internet Protocol) is a universal anonymous network layer. All communications over I2P are anonymous and end-to-end encrypted, participants don’t reveal their real IP addresses.

I2P client is a software used for building and using anonymous I2P networks. Such networks are commonly used for anonymous peer-to-peer applications (filesharing, cryptocurrencies) and anonymous client-server applications (websites, instant messengers, chat-servers).

I2P allows people from all around the world to communicate and share information without restrictions.

  • End-to-end encrypted communications

  2. Didn’t install UBUNTU 16.04 – after the “install i2pd” entry, I got “E: Could not get lock /var/lib/dpkg/lock – open (11: Resource temporarily unavailable)”

    Any clues of how to proceed next?

  3. I had to make sure to create .i2p.config file and add in “SUDO” to it.
