From the developer:
GNUnet is a framework for secure peer-to-peer networking that does not use any centralized or otherwise trusted services. A first service implemented on top of the networking layer allows anonymous censorship-resistant file-sharing. Anonymity is provided by making messages originating from a peer indistinguishable from messages that the peer is routing.
You may want to check out more software, such as PageScope Network Setup, Veeam FastSCP or CrossFTP Server, which might be related to GNUnet.
