That article performs some sleight of hand, where nodes "control" the currency. Nodes sign transactions publicly, they don't control anything. They can't covertly pick the wrong transaction to sign, if they do it will be very visible.
I mean, I may be wrong, but don't consensus between miners determine whether a block is valid or not? Specifically, 51% of mining power determines this, AFAIK.
