High Quality Content by WIKIPEDIA articles! Bitblinder was an open source software program that allows users to share bandwidth and IP addresses in order to anonymously download torrents and browse the internet. It was first released in June 2009. It was developed by Josh Albrecht and Matthew Kaniaris of Innominet. The software is based on the principles that Tor uses to create anonymity but was designed to be faster and encourage file sharing in addition to anonymous browsing. It currently comes bundled with an anonymous browser based on Mozilla Firefox and an anonymous BitTorrent client based on BitTornado.
