I can't seem to account for over 500 Gh/s worth of the network's PoW. As of writing it's 600 gh/s.
There's hardly 100 GH/s altogether on all the public pools I can find (zpool/hashbag/etc), is there a large pool I'm completely missing?
I suppose this has something to do with all the orphaned blocks and pools not finding a block for over an hour after getting multiple per hour.
