1. We did not lie on Jan 3. We were planning to tape out before the Chinese New Year. On Jan 3 we were informed that the back end team cannot reach their target and need to try another layout. This meant to do some changes in the RTL code and start back end process all over again. We have immediately announced the worst date we could think of for batch 2 and not announced details about batch one because we did not had them. We just got the final data from the back end team 5 days ago. They have now reached their target and are now 99% sure that they'll tape out 1 week after Chinese new year (15-20 Jan).
 
2. We have looked into our competitors claims together with Global Foundries. GF is obviously not at liberty to discuss the specific projects with third parties but they assured us that it is impossible to finish 28nm in 49days and to cover every step. 28nm is very complicated and DRC/LSV and JDV checking takes at least 14 days. The wafer manufacturing takes 0.8days / layer at their highest speed. Our conclusion is that our competitors have deliberately omitted several steps in their advertising and were only referring to wafer manufacturing.
 
3. The tapeout costs millions of dollars. We do not have a customer that paid that much to make a tapeout just for them. We had to think further than 1 month. 1.5W/Ghash is not only electricity problem. The whole power translates into heat, therefore more things are required: power chips, heatsinks, AC, new case design, etc.
 
4. We cannot produce the PCBs without the exact pin layout of the chip. This has not been yet received.  We could not produce the case without the exact heat estimation.
 
5. Black Arrow is the only Bitcoin ASIC manufacturer that has not betrayed customer's trust. While others let the deadline pass by and did not announce anything we have clearly informed our customers of the situation.
The tapeout is almost complete and the path from here to ASIC is clearly drawn in the industry.
 
6. Yes, we should be able to run at 120Ghash/sec according to our tools and Verisilicon. Verisilicon gives us the SS corner for speed and TT corner for power. FF corner can be even faster.
 
For those who do not know:
SS = slow slow - absolutely lower limit (speed & voltage) where it can run
TT = typical typical - normal usage; note that 28nm is rated at 25C but leakage increases dramatically with the temperature. The real power consumption at 60C is only a guess at this stage.
FF = fast fast - higest speed, highest voltage, also the highest power consumption. - we have no data on this, it's only discovered while testing real chips.
 
7. We only have few Bitfuries left. It would mean to give everybody less than 1% of what they have ordered. This i more trouble than it worths.
 
8. The chip is designed in China, manufactured in Germany, packaged in Taiwan. Finally the Prospero will be assembled in China

Why was there no notification on jan 3 that tapeout targets could not be met? Even if jan 3 target was met, based on the current timeline, the feb 24 target would have still been missed. This was not disclosed to us. Why?

Do you know that the BA chip will be two months later than the AM 40nm chip and have worse performance? Why are we continuing with this?

PCB layouts will soon be out or are already out for AM chips.

BA kept from us knowledge that the jan 3 target was missed. That affects trust. We could've at that point in time mitigated our losses if given full disclosure and options.

You still haven't answered questions re: who runs BA at the top, who pays your wages and the Shenzhen address?

Tell us who is running BA? Is it one person? Multiple people? Who pays your wages? And what is the address of the factory in Shenzhen?
Multiple people run the company. I don't know the address of the factory. That's a better question for Bobsag. I've never been to the factory.

Please feel free to chime in here bobsag3 aka Matt Carson. You met with these guys, you are their US reseller. Level with all of us.

Since you're so insistent on this, I'll level with you. I won't get paid till after the release of the minion. I have a different full time job and I do this because I want to help Black Arrow. I don't want to get paid till the release of the minion so all funds could be used for development. So it's not just customers who are affected by this delay. I hope that answers your question.

BAMatt have you discussed we all feel the 25% free hosting is not acceptable as compensation? I think we would all like to know the context of the meeting you had with bobsag this weekend. Also can you let people know how to go about starting the refund process that you offered the other day?

I think it should be made clear that BA intends only to refund you if a new customer displaces your purchase.

Everyone knows that the 25% extra hashing was not well received. We're all trying to come up with better options. I'm not sure how long that'll take to figure out but we're discussing it. I have never met bobsag. The first step to a refund would be to submit a ticket. It may be worth while to wait a few weeks till we can figure out a better compensation plan though.

Thanks, pretty much what I was thinking. Sorry I was under the impression bobsag was meeting the team this weekend to discuss the latest developments. Please try to keep us posted as things develop, Im sure we all agree that lack of communication has lead to some pretty upset people and some wild allegations

You still have not addressed why jan 3 announcement was not made.

Also, it would've apparent to management that feb 24 target would be missed even if jan 3 target was met based on current timeline.

Who made decision to go ahead knowing targets would be missed, especially in light of the fact that difficulty increases is rising exponentially?

Until you tell us who is responsible, BA has not levelled with us in my eyes.

Also, who will be paying you in event minions are launched?

Then BA has not levelled with us. The chip designer should've understood the ROI implications of his announcement. Which implies BA is in a tight spot, which means they're unlikely to come good. Matt Carson better have some real answers, else the wrath of dz coop will fall on him.

Why don't you just submit a refund request?

What do you expect to get out of bitching and moaning?

Sadly I have to agree, I think that you all have some tough questions to answer here and without direct action by your management team the trust of BA will be lost forever.

I think he is expecting to get answers.
Just because he is asking questions does not mean he wants a refund, I know personally I want the equipment I paid for. I think most of us want to see this project succeed not die in the water but some people have to take responsibility for these missteps and lack of transparency.

I too wish they could deliver on time but they missed their tapeout by a month and a half. How will transparency/identities allow us to get our hardware any faster?

I just want to know how we will be compensated for the delays and how refunds will be handled. And as matt said he will get back to us with those answers.

Also will batch1 customers be compensated for preordering early

I'm personally not interested in the name game, that's just distraction trolling that I'd expect from someone who's been spending too much time on 4chan but lacks their style and panache. If you want to resolve the vapourware concerns you could ask BAS to get Global Foundries to issue a brief press release to confirm the works they're underway with for BAS (I'm assuming GF can't do this without BAS permission, commercial sensitivity etc, but if they come to an agreement I can't see it being a problem).

The second point would be replacing the lost GHS, I'd refer to my earlier post. Something like 100% of the hash rate for the same duration as the delay, or 50% hash rate for 2x the delay.. or so on. This would be my ideal solution.

Please have a think & chat and get back to us. Cheers

(From another Matt!)

This may be the most sensible post on this whole thread. If Global were to issue that statement, I think it would put a lot of rumour and trolling to rest real quick.

Full disclosure, I have no dog in this fight, though I was seriously considering getting a couple of x-1's at tax time. With the above suggestion implemented, I still might. They are a better deal than the Antminer, if they aren't vaporware.

How about it, BA?
