| Name | Beschreibung/Ziele |
| GNUnet | GNUnet is a framework for secure peer-to-peer networking that does not use any centralized or otherwise trusted services. |
| Freenet | Freenet is free software which lets you anonymously share files, browse and publish „freesites“ (web sites accessible only through Freenet) and chat on forums, without fear of censorship. Freenet is decentralised to make it less vulnerable to attack, and if used in „darknet“ mode, where users only connect to their friends, is very difficult to detect. |
| MUTE | MUTE File Sharing is a peer-to-peer network that provides easy search-and-download functionality while also protecting your privacy. |
| Nodezilla | Nodezilla is a secured, distributed and fault tolerant routing system (aka Grid Network). Its main purpose is to serve as a link for distributed services built on top of it (like chat, efficient video multicasting streaming, File Sharing, secured file store …). |
| Free Haven Project | The Free Haven Project aims to deploy a system for distributed, anonymous, persistent data storage which is robust against attempts by powerful adversaries to find and destroy any stored data. This model of decentralized system has been classified as peer-to-peer by recent popular media. |
