By not accepting connections from strangers we constrain a lot of attack classes. In our fully distributed setting it is difficult to protect yourself from various kind of attacks, like the Sybil attack. Here we start to deviate fundamentally from the random-circuit building approach, used in Tor. Youtube-like streaming focus and auto-seeding #573 Anonymous seeding and rewards experiments #655 1 TByte of seeding #21, running code: Credit investments test: donate 1 TByte anonymously #23ĭarknet mode: deny any connection with strangers Maximize the yield of your bandwidth by automatically detecting and anonymous seeding of swarms. mining for anonymous seedingĪutomatically boost poorly seeded anonymous swarms.
Toward a Youtube-like experience within Tribler. Improved anti-spam measures, family filter accuracy and metadata in general Show overall tunnel + hidden seeding reliability and performance for a tunnel tests and 50MB downloads. Measure the proxy bandwidth donations and online duration (reliability) of yourself and neighbors. Add to the Tribler debug screen how many unique neighbors have been seen. Advanced programmer-minded feature and debugging. Real-time anonymous tunnels reliability statisticsĮach member of the collective measures their perception of network performance and shows it to the user. Be harsh, Tribler is only for social people! Notify users they are freeriding and disable anonymous downloading. Real-time statistics of your relaying contributions and tunnel ratio Each peer builds a database with the reliability of their neighbors, visualize in a graph (locally no central accountant, controlling server). These proof-of-work records are shared in the community (like Bitcoin public ledger). Double signed signature record is created after proxy helping. Similar to private Bittorrent communities we use the sharing ratio to identify freeriders. Our protocol follows the Tor specification as much as possible, our circuits have a maximum lifetime of 10 minutes and also terminate after 55MByte of traffic (security limiters). Instead of pointless hashing we use proxy helping bandwidth as our proof-of-work. Introduce a Bitcoin-like accounting system. Share with the rest of the network who is actively helping others and who is freeriding.

Ticket: No longer serve by default as an "Exit node" flag #1174 tit-for-tat for anonymityĭevelop an open community to disseminate sharing ratio of participants. If content is "pulled into the darknet" we can switch to end-to-end encryption and rely on hidden seeding. Ideally, only a single copy of each piece of content needs to be relayed by our exit nodes. Lawyer-based attacks are very real for exit node volunteers. Running an exit node has proven to be a risky non-trivial task for the main Tor community.
These are the peers that receive encrypted messages from the darknet and unencrypted messages from Bittorrent peers. Our smooth backwards compatibility with Bittorrent comes with the cost of exposure in existing Bittorrent swarms.
Tribler users never become an exit node, unless they explicitly volunteer. Fallback option background: anonymous seeding and public-swarm fallback policies #885
This feature can be disabled easily if you prefer pure darknet-only downloads. Tribler offers this fallback option by default after trying for 180 seconds.
OPT INTO TRIBLER DOWNLOAD
If there are no hidden seeders available, you can anonymously download from normal Bittorrent seeders. It always prefers downloading from hidden seeders using end-to-end encryption. Tribler can download from both hidden seeders and existing Bittorrent swarms. Hidden seeding requires connectability of rendezvous and introduction points. This ensures sufficient content becomes available with strong privacy in our darknet. Hidden seeding is the default in Tribler for sharing content and cannot be disabled. Tribler users never seed naked in Bittorrent swarms.īittorrent swarms offer no protection, they leave people exposed and naked. slow anonymous downloads: Crypto CPU bottleneck #1882 Currently our GCM cypto or other bottleneck is slowing things down. Only 330KByte/sec is unacceptable for our video streaming use-case.
