Hi All, We have implemented parts of the Tor protocol in Python, it uses UDP and integrated it with a decentralised gossip-based directory service.
Today we're launching a public trial for testing and feedback. We hope this could be an alternative for avid torrent users and move some of the file sharing load (50%) away from Tor. This trial in no way connects to the Tor network. Feature under test: router are behind NAT and use UDP puncturing to create 3-hop tunnels This is very much work in progress and under active development. We tried to follow the Tor message specifications as best as we could and use UDP exclusively. Our todo list is still long, for instance, DTLS is not yet used. Help welcome.. All participants in our trial automatically become guard/relay and exit node for a single Bittorrent test swarm. Congestion control is end-to-end, done by LEDBAT within Libtorrent. The trial network does not use directory authorities. Every client includes a list of hard-coded IP addresses to bootstrap. Every participant contacts them and then builds up their own view of online routers using gossip messages. This makes this network vulnerable to a wide range of attacks, especially the Sybil attack. Our full decentralisation clearly weakens security. Our motivation is to empirically validate one possible design alternative, one fully focused on decentralisation and scalability. details: https://github.com/Tribler/tribler/wiki/Anonymous-Downloading-and-Streaming-specifications code: https://github.com/Tribler/tribler/blob/v6.3.0/Tribler/community/tunnel/community.py#L271 press: http://torrentfreak.com/tribler-makes-bittorrent-client-anonymous-built-tor-network-140902/ about us: http://tribler.org/about.html Greetings, Johan Pouwelse, Delft University of Technology -- tor-talk mailing list - tor-talk@lists.torproject.org To unsubscribe or change other settings go to https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
