Very cool.  Congrats!

looks like all of their engineering went to their terms & conditions pages

blackarrow

Your device (X-1 and X-3) is based on SHA-256 or own script?
If they are fit for mining Cryptocurrency (Litecoin, Namecoin, PPCoin) or only Bitcoin?

Thx!

Would be good idea to ask mining.thegenesisblock.com to include your miners on their site? At least you have very competitive $ /Gh.

I would say the same things from my conversations with them.

Just want to thank the Black Arrow team for taking some time today to talk. It is really refreshing to deal with people who first know their product and the technology involved and secondly to come across very personable is just a bonus. They are definitely passionate about what they are bringing to the marketplace without the need to oversell it with useless "sales" talk. This is definitely the 28nm chip to watch. I am hopeful our project team gets to use some of these chips in our build.

Why would you assume that? What would be the point of denying root access to customers? It would only bring headache to BlackArrow.

If core devs request miners upgrade their mining code right away to avoid a bug or add a needed feature, would Black Arrow provide a way to patch the Prosperos?  I'm assuming customers won't have root access to their devices.
--edit:  add "  Will the patch be optional to the customer or will it happen via an auto-update feature?"

We've enlarged the DIE size by switching from 48 cores to 64 cores. This was possible due to lower power consumption achieved by our engineers.

We did not have Credit/Debit cards payment method available on our website.

We have approached various credit card processing vendors. As soon as we find one willing to work with pre-orders, we will be able to process credit/debit cards.

We do not know when and who will that vendor be.

Was planning to place an order with CC, but I guess will need to hold this off for now.

Any idea when you will get the CC payments rolling again?

Cheers

Not really following the thread but last time I checked the X-1 was 64GH/s, how comes that now it runs 100GH/s? Also the discount is now 35% from the website. Looks good, I'll consider doing a preorder if the offer lasts.

After consulting with one of our prospective resellers, who have had more interaction with PayPal than we have, we understood that PayPal’s business model does not fit very well with pre-orders. Because our delivery date is over Paypal’s 90 days delivery threshold, we risk having our PayPal account blocked with all customers’ money in it. If such a thing were to happen this might cause huge delays in deliveries and we want to avoid this at all costs.

Our merchant account with PayPal is currently working but we have decided to suspend all future PayPal transactions for items that are not in stock (pre-orders). We have contacted and are currently talking with PayPal to ensure that they understand our pre-sales agreement and to obtain the guarantee that everything is ok, all security checks are done and our account will remain open.

We will reactivate PayPal payments as soon as we get PayPal’s approval in writing or as soon as we will be able to meet 90 days delivery condition, which means closer to the release date of the Product.

We have also approached various credit card processing vendors. As soon as we find one willing to work with pre-orders, we will be able to process credit/debit cards. However, because this process might take longer than the time required to sell our first ASICs batch, we hope that the absence of the Credit/Debit card process will not stop our customers from placing orders with us.

Orders placed and paid so far with PayPal are safe and we intend to deliver them as promised. However, if any customer changes his mind and wishes to pay with a different payment method or cancel his order, he/she is welcome to do so. Please drop us an email and we will issue a refund as soon as we read your message.

Or another company sells, say, 2TH/s for 4000$ and you get 25% back either with more hashing power or a partial refund (I guess more hashing power).

Same thing as BTC @ 160$.

+1

+1, and this really counts for any current ASIC provider. I will state my opinion and some facts in this thread because I believe BA is one of the most serious companys in here and has been a proven business partner to many customers, in contrast to many other, new and even established manufacturers that burned their customers money already:

1. With a growth rate based on the experiences of the last months concerning the upcoming mining devices as well there wont be any positive ROI on these or any other devices sold today for the called prices.

2. I am afraid at costs of 270 USD also a Prospero X1 even delivered on time at the end of february will not break even anymore: http://btcinvest.net/bitcoin-mining-profit-calculator.php?diff=148819199.80509&dcosts=270&diff_mincrease=30&blpbtc=25&dhsmhs=100000&diff_mincreasedecrease=0.1&btcusd=129.50&dpowcon=50&btcusd_mincrease=0&pcost=0.25&calcweeks=20&dleadtime=13&action=calc

3. Even without power costs and with mining-friendly decreases in growth rate there is no way to mine back the FIAT invest before 2017 at the current BTC value: http://btcinvest.net/bitcoin-mining-profit-calculator.php?diff=148819199.80509&dcosts=270&diff_mincrease=30&blpbtc=25&dhsmhs=100000&diff_mincreasedecrease=3&btcusd=129.50&dpowcon=0&btcusd_mincrease=0&pcost=0.25&calcweeks=99&dleadtime=13&action=calc

4. And next, even if BTC value increases, it would have been safer to buy bitcoins as they are delivered instantly, and the profit would be much bigger too.

I'd like love to invest in bitcoins or in supporting the network, I would also don't mind to pay a company for a mining device that empowers me to do this. But I won't burn more money on mining devices that probably will not get back the paid money valued in any currency calculated with todays prices.

IMO it's not a complete mistake to choose this high pricing because many will simply buy coins instead of mining devices. You are supporting the increase of bitcoin value. If this happens fast enough, it might be also possible to mine back the FIAT value of your mining device:

http://btcinvest.net/bitcoin-mining-profit-calculator.php?diff=148819199.80509&dcosts=270&diff_mincrease=30&blpbtc=25&dhsmhs=100000&diff_mincreasedecrease=3&btcusd=129.50&dpowcon=0&btcusd_mincrease=1&pcost=0.25&calcweeks=99&dleadtime=13&action=calc

But obviously this is gambling - on top of some more layers and corners than buying bitcoins right now would be. Buying mining devices in the current market situation at this pricings with a foreseeable loss (because it could end up sooo fine) is like you're dreaming that you are dreaming some dreams - of a imagined profit (btw. need to watch inception again).

BlackArrow, you got a nice product but I think feb 2014 is too late for this pricing from todays perspective. Your current pricing IMO is made for BTC value at 160 USD at least:

http://btcinvest.net/bitcoin-mining-profit-calculator.php?diff=148819199.80509&dcosts=270&diff_mincrease=30&blpbtc=25&dhsmhs=100000&diff_mincreasedecrease=3&btcusd=160&dpowcon=50&btcusd_mincrease=1&pcost=0.25&calcweeks=99&dleadtime=13&action=calc

I think, BlackArrow is an interesting option, this one and Cointerra at least for me are 2 good ahead from the rest.

BA answer fast and looks like he try his best to clarify and provide information.

But I have one opinion for all the ASIC providers, they say they can’t provide a business proposal that may make them loose money because if they do that they may go bankruptcy, if that is correct some may agree some not, but if is correct should apply for both sides of the deal, what I see in 99% of the recent past deals is the miners can loose money and will loose money but ASIC providers ask us to guarantee their profit.

Sorry if I hurt someone.

I think Black Arrow has provided more pricing detail than any other pre-order ASIC offer - he quoted several prices (depending on % paid in Sept/Oct or if using trade-ins by Oct 5th), and then promised to match-25% essentially in $/GH/s what the best Feb 24th off-the-shelf pricing of a comparable product to the Prospero is.  He also implied he can't go below $0.5/GH/s.  Now my guess is his company will be forced down some, but nobody can  predict the future....and his promise tells me that we who trust him and pre-order will (if all works out) get a relatively great deal for our miners....and our ROI will be as good as any others (positive or negative) at that Feb 24th point in time.  If the difficulty keeps rising at more than 60% per month, then ROI will be negative for us even at the $0.5/GH/s bankrupting level....and I'd assume the same for other ASICs products.  However, I'm figuring in December the difficulty will taper off its rate of climb due to less energy efficient (W/GH/s) miners turning off their mining equipment due to cost of power.  (At 100B difficulty, only systems more efficient than 0.3 W/GH/s at $0.1/KWhr can afford power to run. --ediited this last line from a guess after doing the calculation at the mining dashboard http://mining.thegenesisblock.com/ .)

Are you taking bets on that ?

None of this should be the customers problems.  As I stated before you keep trying to say anything and everything to get pre-order monies but still no actual set pricing model.  Even if one believes your ability to manufacture this everything else is all over the place.  Customers don't need essence they need an actual price but you certainly appear to not want to give a price.  What happens to your "guarantee" if market prices at the time of shipping happen to be below your costs?
