Taking a leap of faith and put an order for 4...
I'll let you know in June if i got scammed :p

Did you use Paypal?  So basically if you pay by Paypal this is pretty much risk-free no?

Paypal would cover it if its an online purchase. But not if its person to person transfer, I think.

There is an address in the payment methods in the online store 455yPxusDp2EPBTWhLqmPS7ywgWvCY8hJ7cgFL2ggpWRR6brgi9QS2yVZeBYHuWPpr9HfDkCVqnE5T1 1LnTFgAD5DYN3CdD  Maybe this is the right one?

Xmrpool.net shows zero for that address, last hash: never?

You need to delete space between 11 in that address.

Hello everybody!

We are happy to inform you we will start selling!

We hope to answer faster in the sales period Smiley

A lot of time was spent to the organization of production. It was necessary to arrange the delivery our chips to China, discuss the terms of assembly rules, find a replacement for European components in Asia. Instead of one week, we spent four. But now the whole chain is built!

Yesterday we have begun manufacture of five thousand pieces. It will be ready on June 18. After that we will begin to send orders in the order of payments (first paid - first received). To cover your risks we offer a discount during this period.

Work demonstration you can see on our youtube channel: https://www.youtube.com/channel/UCz6buvT87nX-NuEkfcrNQGg
It does not have a fee, but updates will be charged. We expect $20-50 for each new algo. At now it is tested with monero, graft, haven, sumo and loki. The same coins should work too.

Our online store is available here: https://dwarfminer.webasyst.cloud/shop/  You can find there description and characteristics of the good. You must add to cart the number of devices and delivery to your country. The cost of delivery includes no more than four units (a parcel weight limit is 500 grams). If you need more, please contact us: [email protected]

All orders (except monero payment) are made through the manager to eliminate confusion. The exchange rates will be fixed at the order's time.

I looked up the address in the video at xmrpool and it shows 0 hahses submitted or 0 payments made!

its not clear when will be shipped, well, to be precise:
its not clear who(company in china ?/europe?)  is going  to invoice, when payment will be requested compared to when the product will be shipped

Hi all!

--This is very efficient. almost as efficient as the ASIC.
ASIC uses an array of chips for operation. You can see it on the baikal boards. We use one chip. It consumes as much as in ASIC.

--The circuit board doesn't look that exotic.  Doesn't need MIL-spec anything. 
This is a eight-layer board. All the magic is inside. Most chips have BGA packs. This can be mounted automatically only, with X-ray control.

--If they give it a good review, you'll be flooded with orders.  Your bankers will be impressed.
We are flooded with orders now. Five thousand is too small batch to wait for a review and wasting time up to fork. We made a discount now to cover the risks. The next batch will be bigger and more expensive.

-- Please put me on the waiting list  Grin thx
We have free pre-order. But the batch has not yet sold out Wink

--Your board looks strikingly similar to the first x11 fpga's, except they needed a fan to cool.
in a warm climate it need a fan too

--de hecho, por las fotos, parece que somos "vecinos"
algunas personas - si Wink

--Well, guys, if you are in the Euro zone, that change a lot.
Developers are located around the world but the leader is in Madrid.

-- I will fly in anywhere in Europe to see samples
there are only prototypes and they are all in China now. The whole batch will be made and sent at one time.

--DwarfMiner, tell us more about the architecture of the system  Cheesy
We use a hybrid chip containing FPGA, memory and AES coprocessor. This allows to change the firmware, in contrast to ASIC, in which the entire chip is made on a single crystal.
This means all typical elements are fast, but the algorithm section is made flexible.

--Even if $100 = 500h/s for 7 kh/s will cost $700 and OP wanna sell for $350.
iPhone about three times cheaper than its component parts cost in stores. Because the factory buys millions chips.
We have released a quarter of a million chips. It's much cheaper than buying one IC.

--would like to see pics or videos here and not in zip files
tomorrow

--Newbie with activity 1 selling ... ----> SCAM
Activity: 98 this is much better.

I think you're completely ignoring memory latency for implementing the hash function.
I gave the example of the simplest and cheapest memory. You can find faster memory, distribute it in parallel. I used memory inside the FPGA and achieved 3.5 kh. But it was more expensive, of course.

But like other users said, it is too good to be true.
I do not think so. Look at this article: https://www.iacr.org/archive/ches2005/031.pdf
The hash function has a 524288 cycles, if I understood everything correctly.
From the article:
"Two new FPGA designs for the Advanced Encryption Standard
(AES) are presented. The first is believed to be the fastest, achieving 25 Gbps
throughput using a Xilinx Spartan-III (XC3S2000) device. The second is
believed to be the smallest and fits into a Xilinx Spartan-II (XC2S15) device,
only requiring two block memories and 124 slices to achieve a throughput of
2.2 Mbps. "

It means, XC3S2000-5 for $78 only can generate 1490,12 h/s; https://www.digikey.com/product-detail/en/xilinx-inc/XC3S2000-5FGG456C/XC3S2000-5FGG456C-ND/1951750
+ SRAM memory like https://www2.mouser.com/ProductDetail/GSI-Technology/GS8160Z36DGT-150?qs=sGAEpiMZZMt9mBA6nIyysJQc0%252bdJyBlRwbATLGJ3Hts%3d, $14 for 2,25 megabyte.
About a hundred bucks for one and a half kh. And it's using the components from the online store. If they use an external AES coprocessor, this can work faster.

DwarfMiner, tell us more about the architecture of the system  Cheesy

I dont think that things work like you said.
Even if $100 = 500h/s for 7 kh/s will cost $700 and OP wanna sell for $350.

But it is very simple, like i said before, OP just need to give more information and prove the truth.

Your sram supports a tiny bandwidth of 36bit*260 in read only, In read/write turnaround it only supports 133Mhz. That’s only 600MB/s. Since it takes 32MB/s for each hash you’re only getting 20H/s or worse.

AES is not the bottleneck.
