Building a BitTorrent client from the ground up in Go

Over the holidays, I challenged myself to learn Go by torrenting the Debian ISO -- from scratch. This post is a bit of a brain dump about everything I've learned over the past week.

Any chance you'll do independent write ups to cover all the missing bits? Especially the ones that build character. :)

Would also be good to include how BT uses a merkel tree, that's quite a key component in the software.

Does any client support the new standard? I was under the impression that no one did.

It doesn't until the second version, which isn't mainstream.

Wow, I've been looking for a BT tutorial at about this level of abstraction for two years or so. And would have liked to have read it a decade or two back as well.

Wondering if there are any similar docs or a book for implementing a server in Python, and a client in Python or Dart/Flutter? I know libtorrent bindings are a thing but the docs seemed quite dense and I didn't even know where to start—until now that is.

Here's a pretty good one in JavaScript: https://allenkim67.github.io/programming/2016/05/04/how-to-m...

Same same. But just in Javascript more.
