BlackArrow has been claiming that somehow running a Bitfury mine is proof that they can deliver their own design.
They never made such a claim. Instead someone visited their factory and took pictures of a bunch of bitfury boards there were running. That's all.
I am, however, still waiting for an explanation of what all those boards are doing there. They were said to be customers' boards. If that's so, why haven't they been shipped out to those customers?
