Write a BitTorrent-client in Go

by Ritwik Saha, September 13, 2019

BitTorrent is a peer-to-peer (P2P) file sharing protocol over the Internet, where a computer can join a swarm of other computers to exchange pieces of data between each other. Each computer that is connected to the network is called a Peer. And, each peer is connected to multiple peers at the same time, and thus downloading or uploading to multiple peers at the same time. Unlike normal downloads, a torrent download doesn’t put any signoficant load on a single peer’s bandwidth, so it’s faster.

What this post is for?

In this tutorial we are gonna write a BitTorrent-Client from scratch in Go. Our focus will be downloading files from the peers. We are not gonna focus on file sharing for now. By the end, you can download files via the BitTorrent-protocol from the command-line.

Where’s the “tutorial”?
