I’ve bene running a Tor exit node in the Netherlands since August 2013. I believe in the cause of Tor and it was only a matter of time before I started adding code in some for or another.
gonionoo is Go wrapper for OnionOO – the Tor Network Status protocol as is the first step in a slightly larger project I’m working on that I’ve been planning for a while ever since I’ve became a Tor exit node operator.
The OnionOO API has lots of interesting data on the Tor network. You can see it visualized as part of the Atlas project.
