The leak was posted on the 4chan messaging board as a 125GB torrent, which is said to include the entirety of Twitch and its commit history within it. This means the source code for the streaming giant is online for anyone to access, including all past and current versions of the site. The leak was labeled as “part one”, implying the existence of a second torrent, but nothing has been released so far. The leak does not appear to include any personal information for its users, but it includes a full history of payments to creators from Twitch.
