Thank you for your interest in contributing to I2P!

For almost two decades the Invisible Internet Project (I2P) has researched and developed a transport layer and software with a focus on providing privacy and security for online communication. The Invisible Internet Project (I2P) supports the right to access. The project works to constantly improve its circumvention abilities and resistance.

Both the network and its software is completely free to use.

Who Uses The Invisible Internet?

People who are concerned about their privacy and interested in alternatives to the internet make use of the network and its applications to chat, email, torrent and run their own sites and forums. In some circumstances individuals rely on the network to communicate due to safety issues or censorship. Researchers, developers and digital rights defenders make use of the network as well.

How Is The Invisible Internet Project Funded and How Is That Funding Used?

The Invisible Internet Project (I2P) is 100% community funded. In the past the Project has received a grant from DuckDuckGo, and has received support from the OTF Usability Lab providers. This helped to guide improvements to the Java software and website UX and information architecture. Donations support I2P maintainers server costs, and other costs associated with keeping the network services up and running. Donations support improving the I2P protocol, application layer, outreach and design.

I2P accepts donations in cryptocurrencies and via Paypal. Android users may also support the project through the Google Play Store by choosing the "Donate" edition. I2P funding is handled by meeh.
