scala-torrent

A BitTorrent client for which I implemented a P2P protocol over TCP, making torrent downloading fully functional, and a DHT (Distributed Hash Table) from scratch, enabling decentralised peer search. It uses the Akka actor system for concurrency.

In the demo above we're downloading Sintel, an open-source film.

This is a fork of TheDom's project. They did the initial work up to Handshakes.
