2002 according to https://en.wikipedia.org/wiki/Kademlia - and this is a nice article for the layman (who still understands basic CS) to understand it.

I'm a bit dubious about where the name "Kademlia" came from :-)

> Where does the word “kademlia” come from? What I know is—it is a Turkish word for a “lucky man” and, more importantly, is the name of a mountain peak in Bulgaria.
