How does an entity that designed and built the best mousetrap known to man go bankrupt, while inferior mousetrap manufacturers continue to exist, supplying their customers with highly sough-after sub-par products?
You act as if HF is the first company in history to go bankrupt despite having a superior product, but you are far too old for that to be the case.
Yes, HF is the first bitcoin manufacturer in history to spend ~$15m on NRE and design a chip that is only on par with the competition.
BTW where is the document that outlines Hashfasts expenses? I've been looking through the documents here but can't seem to find it:
https://cases.processgeneral.com/cases/document/case/5/hashfast-technologies-llc/Both definitions are correct, but in common usage the complete die(s)+substrate package constitutes a chip.
No both definitions are not correct. A substrate is just the board part of any PCB (other part is components/copper traces). There are no ASICs that do not go on a substrate.
If I'm wrong, please tell the class what competing die(s)+substrate object offers higher performance than HF's. Come on, don't be shy. You can do it! Oh wait, no you can't.
I'm assuming you mean in terms of gh/s per substrate so here's your useless comparison:
Hashfail - 750 gh/s
Cointerra - 800 gh/s
SP10- 800 gh/s
SP30- 2,250 gh/s
BFL monarch - 800 gh/s
Since you want to be a pedant, let's just agree that HF's GH per sq mm of wafer is the highest of any design, regardless of how obnoxiously narrowly you want to define "chip."
If anyone is being obnoxious it's you. Nobody cares about how much gh/s you can fit on a chip/pcb. What's important is the $/gh and w/gh for complete hardware not just the chips.
Yes the golden nonce is very good in terms of $/gh (~$0.1/gh I'd guess) but the w/gh is horrible and the amount of money they spent on engineering completely negates the production cost savings.
