You may have noticed yesterday that STEEM was offline for multiple hours. It was all related to a negative power down initiated by @nijeah 8 days ago. Once the power down attempted to move SP to liquid STEEM the block chain froze. Seemingly a very simple bug in STEEM that surprisingly had yet to be discovered. Hopefully there aren't anymore of these chain stopping bug out there!
If you want to read more about the details of the chain crash they can be found here. Also, included is some witness drama....
