dht in Tenen & Foxman 2014
erable to charges of
aiding and abetting copyright
infringement.^[43](#fn-2025-43){#fnref-2025-43}^ Early in 2008, Cohen
extended *BitTorrent* to make use of "distributed sloppy hash tables"
(DHT) for storing peer locations without resorting to a central tracker.
Under these new guidelines, each peer would maintain a small routing
table pointing to a handful of nearby peer locations. In effect, DHT
placed additional responsibility on the swarm to become a tracker of
sorts, however "sloppy" and imperfect. By November of of 2009, *Pirate
Bay* announced its transition away from tracking entirely, in favor of
DHT and the related PEX and Magnetic Links protocols. At the time they
called it, "world's most resilient
tracking."^[44](#fn-2025-44){#fnref-2025-44}^
Despite these advancements, the decentralized model of file sharing
remains susceptible to several chronic ailments. The first follows from
the fact that ad-hoc distribution networks privilege popular material. A
file needs to be actively traded to en
tent to log IP
addresses.^[46](#fn-2025-46){#fnref-2025-46}^ Researchers exploring this
vector of attack were able to harvest more than 91,000 IP addresses in
less than 24 hours of sharing a popular television
show.^[47](#fn-2025-47){#fnref-2025-47}^ They report that more than 9%
of requests made to their servers indicated "modified clients", which
are likely also to be running experiments in the DHT. Legitimate
copyright holders and copyright "trolls" alike have used this
vulnerability to bring lawsuits against individual sharers in
court.^[48](#fn-2025-48){#fnref-2025-48}^
These two challenges are further exacerbated in the case of *Aleph*,
which uses *BitTorrent* to distribute large parts of its own
architecture. These parts are relatively large--around 40-50GB each.
