Thanks for your questions.
Assume one chip is consuming 5-10 Watts (per GHps), your 12THps rig would pull 60-120kW from the wall. Now that's a fat power plug for those used to limit their mining rigs to 1.5kW
Are you prepared to facilitate according needs?
Yes. For a 60-120kW operating, the most similar places are local net-cafes. Larger ones have different electricity cables more close to those of industrial uses than family ones. This is why we have taken the place rent into consideration, it also contains the effort of (industrial-level) power supply.
Second, are you prepared to secure the proper continuous operation of that 12TH rig in terms of immunity to external impacts? We see how the large pools have been under DDoS attacks every now and then and needed to gradually implement counter measures to provide their services. Now if you pop up with a hashing power worth the largest three pools have combined, you inevitably become a target. Are you aware of those risks, and prepared?
Yes, we are aware of those risks, but we haven't immediately began to work on it because currently the highest priority is making our IPO succeed, our design reliable, and our production on time.
In fact there might be more "real-world" attacks like theft. All of them should be finally taken account. We feel that, solving them in parallel with the mask-set production as well as PCB production, are a good idea.
Thanks for your answer and the transparency you provided so far.
You are welcome. More questions and suggestions are always welcome.
