zigtorrent

Toy Bittorrent (original spec) CLI client that serves as a learning proyect for myself so its not expected to work optimally.

Features

• Download a piece
• Download a file
• Succesfully downloaded a debian iso
• Multithreaded (works but is a bit experimental)

Todo

• Better piece selection
• Better peer selection and keeping track of them
• More testing (ie. torrents such as ubuntu iso don't work)
• Dont upload the entire file in memory. Just preallocate a file and seek and write to it.
• Multifile torrents
• Magnet links
• Support seeding
• DHT
