PoW² explored — A post-launch look at some of the security implications

This is the first in a series of articles I’ll be doing that focus on various aspects of the latest gulden release and PoW² specifically; I’ll be releasing more articles over the coming weeks each focusing on different aspects of the system or from a different perspective — so follow me if you want to know more.
