StrongU made a Blake2b ASIC for Sia, called the U2, before it knew that Sia was forking away to Blake2b-Sia. The fork made the U2 useless for Sia. But now StrongU has put a huge 1.4PH farm of the U2's on Hyperspace. You can see the farm at the top of miners listed at Luxor.
The U2 is the fastest Blake2b ASIC currently available, at 7TH.
With this new farm, the network hashrate for Hyperspace is now at an all-time high of 7.5PH and difficulty is at an all-time high of 3.5PH. StrongU's farm is the largest that has mined Hyperspace so far, by a factor of 3.
