Bram Cohen: The Creator of BitTorrent Who Revolutionized File Sharing

The world of file-sharing was revolutionized when Bram Cohen created the BitTorrent protocol in 2001. His peer-to-peer file-sharing system allowed users to download shared files quickly and efficiently over the Internet. Cohen's invention has since become the most widely used protocol for distributing large files, and countless movies and songs have been made available to the world through his system.

Born in 1975, Cohen had already begun coding by the time he was 13. He later went on to refine many popular technologies and enjoyed researching computer network protocols. Though his work was mostly self-taught, he also did brief stints at diverse companies such as Bell Laboratories and IBM. After years of research and hard work, Cohen created BitTorrent and the concept of file-sharing was changed forever.

So what makes BitTorrent so different from other file-sharing systems? To understand this, one must first understand the basics of file-sharing protocols. Most file sharing protocols before BitTorrent required users to upload the entire file before they could begin downloading, thus becoming a kind of middleman between the originator and downloader. This would often cause the file sharing process to be slow and inefficient. By contrast, BitTorrent used random network connectivity to facilitate quick file transfers and allowed the downloader to immediately begin downloading even while still uploading the file.

Perhaps one of the most important aspects of BitTorrent is its use of a distributed tracker. This allows for faster transfers and more efficient use of bandwidth by continually updating and providing clients with a list of peers hosting the same file. It also makes it possible for clients to connect to more peers which reduces latency. Other protocols were unable to match the speed and efficiency of BitTorrent, and it quickly became the go-to protocol for peer-to-peer file sharing.

But despite its popularity, the BitTorrent protocol has had its share of controversy. In 2007, the Motion Picture Association of America filed a lawsuit against Cohen in an effort to have the protocol shut down. This sparked a heated debate between various parties on whether BitTorrent was actually responsible for the illegal downloading that had become so commonplace. But thanks to the efforts of countless individuals and organizations, the lawsuit was eventually dropped and BitTorrent survived.

In 2018, Cohen was awarded an Emmy for his groundbreaking invention. He has since gone on to found several other successful startups, including Chia Network which seeks to improve the scalability and security of the blockchain. Whether you use BitTorrent or not, you can’t deny its importance in revolutionizing file-sharing. It’s hard to imagine what file-sharing might look like today without it.
