I am not sure if you picked up it but it looks like they just purchase a batch of Avalon or BFL Chips and are re-packaging them into a solution. I am leaning towards Avalon. If you buy a Avalon batch then you get 3 Th per batch. Nothing suggests that this is there own chip.
Yes, they are doing their own chip. Not BFL or Avalon AFAIK.
was about Alydian's order: 1+ million 65nm chips...
