In peer-to-peer file transfer, the properties of privacy and performance are often mutually exclusive. Although there are a wide variety of peer-to-peer applications and networks which attempt to close this gap, even the most elegant systems still present privacy and performance as start trade-offs to one another. Amidst continually increasing concerns about privacy, as well as ever growing amount of data being transferred, a peer-to-peer system which provides a more balanced approach to anonymity and performance is desperately needed. In this research, I propose a new system called Excelsior which embraces both of these properties in a hybrid network utilizing DC-nets, entanglement, and BitTorrent-style content distribution. This system is designed to provide a simple and straightforward means for the ubiquitous BitTorrent to vastly increase user privacy with the minimum possible performance sacrifice.
