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 think you're completely ignoring memory latency for implementing the hash function.

Still, if any solid proof comes out, stating and proving that this little thing indeed exists and hashes as good as told, I will definitely buy it. It just seems like the perfect way to mine without using mad amount of electricity.

Really hope this turns out as a real deal Smiley

Thats how scams work, the ones that dont see 350 as a big loss if they are scammed are the ones the scammer depends on. It would be nieve to think bitmain wont enter this FPGA mining scene after the x3 debacle. They already use them for other things.
Yes, agreed. I wonder how many scams of 300 euros one can be part of until they realize they're throwing away money  Cheesy Now, I'm not saying this is a scam, I'll give OP the benefit of the doubt.

Bitmain will definitely enter the FPGA scene if they haven't already in secret. But since FPGAs are more comparable to GPUs (when it comes to hash rates) and not as powerful as ASICs, this could be a turn for the better.

Come on guys... give the OP the benefit of doubt until proven otherwise.  If the original quoted pricing holds, what's $350 in the big scheme of things?  I wasted more than that by dropping a GPU that no longer works... LOL!

When they do go on sale, I'd bet someone here is willing to gamble $350 on a few of them!

That's a bad plan but you're welcome to go forwards with it and you can also let us know how it worked out for you  Grin

If things can be easily tweaked to avoid possible scams why take the risk?

This isn't Vegas and the roulette table, it's science  Cheesy

Well, guys, if you are in the Euro zone, that change a lot.

I 'm interested in a sizable number.
I will fly in anywhere in Europe to see samples

 DwarfMiner, don't listen to naysayers and "scam" callers.

 If you need social validation by a trusted member, I am happy to provide it.

 I am euro-based which I presume you are too, so things should be very easy to setup.
Your board looks strikingly similar to the first x11 fpga's, except they needed a fan to cool.

 PM me. I've been officially involved with a few blockchain projects, including a previous top 5 coin, all of which can be verified with my real identity.

(de hecho, por las fotos, parece que somos "vecinos" ... )

This sounds great and if it works as promised 5000 units will be easily sold when they became available.

Very good words and presentation but no one will trust in you.
You need to prove that it is real, some people have already suggested how to do:

-Give 1 piece to a legendary respectable user that can do a good review of the product.
-Escrow the payments.

But like other users said, it is too good to be true.

Yes, I agree anyone who will buy this without an escrow will be exposed to a certain degree of risk. Sorry OP.

I wouldn't trust any Legendary or higher ranked members on this because anyone can be easily bought but certainly it's better than nothing.

..If it's still profitable when it's ready to ship I'd order a couple of them.
..We have not started selling yet. Negotiations with producers and banks are VERY slow... Sales will begin when we receive guarantees from.

The DwarfMiner /may/ be more feasible than that other $5K-$6K FPGA project if you can get it shipping soon.  The circuit board doesn't look that exotic.  Doesn't need MIL-spec anything.  

        Get a couple demo/eval units in the hands of trusted reviewers here.  
  
If they give it a good review, you'll be flooded with orders.  Your bankers will be impressed.  Your suppliers/producers will be reassured and confident to build the boards.

We all know time is money.  Sooner is better.

Interested also, like all the other members.  Prove its real, and way to pay without being scammed.  Looking forward to updates.

We are a group of developers from different countries. After working over the last six months we are ready to present the result - an ecological "green" miner.
Usually, ASICs are designed for “industrial mining” and they are expensive. In addition, these devices threaten decentralization. Changing the mining algorithm involves the risk to not recoup investment.
GPU mining is more flexible but produces a lot of heat and noise. This accelerates global warming and increases the owner's costs. This forms a feud with gamers!  Grin

We have developed an intermediate product. This small device is able to replace one rig and produce 7 kh /  10 W on the v7 and 3.5 kh / 8W on the heavy.
 

This is very efficient. almost as efficient as the ASIC.
