They should be sending out free prototype chips like other companies which develop new technologies do!

LOL, that'll be the day. Try-before-you-buy dedicated mining hardware.

Soo... Now i'm wondering how many people have 'invested' in this guy.

Anyone dare to speak up?

Which was why I was asking him what part did he used since I expected there would be at least two trip up. The first being unless there's some really super fast breakthrough Flash chip, it would be pretty much damning evidence regardless of his answer Cheesy

Aha - cunning!

There's no reason why a specially-designed Bitcoin mining board would need an SRAM chip; SRAM is large and slow and a Bitcoin miner needs fast access to a small amount of data. This wasn't even a competent scammer...

Use of Block RAM (BRAM) for storage of constants [8]. Reconfigurable hardware devices
such as FPGAs often have on-board memories which can be pre-loaded.
Storing the Kt constants in these memories frees up space in the device
which can then be used to implement extra logic. The free space also leads to
improved routing and, thus, a general speed-up in circuit operation.

As a person who's actually done an FPGA bitcoin mining design that uses block RAM (though not in exactly this way), I know that it's part of the FPGA itself and not a seperate chip. There's no reason why a specially-designed Bitcoin mining board would need an SRAM chip; SRAM is large and slow and a Bitcoin miner needs fast access to a small amount of data. This wasn't even a competent scammer...

Edit: Oh, and the reason it doesn't use block RAM in that particular way? Doing so is only worthwhile if you're designing a standard SHA-2 hash engine that computes the hashes of variable-length pieces of data one at a time, whereas efficient Bitcoin mining compute lots of hashes of differing short pieces of data in parallel.

Well if you try to call there, his phone is turned off cause of insuffcient funds...
i guess the HK Police Department will prosecute this, if you didnt get your refund aswell:

For anyone still in doubt, I can confirm that it is, indeed, a SCAM.
See his post on reddit:

We're currently about to close the sale of a whole first batch of devices to a private investor. We will be required not to duplicate the device for at least 3 years. Sorry guys. We will eventually refund all the people who sent the 5 btc within 48 hours.

And just last night he sent me an email:

Quote

Hello,

Thanks for taking the time to write us an email.
We will have a couple devices left to sell.

Entry level device with 2 boards price breakdown :

Controller device $150.00
ASIC board $250.00 x 2
Shipment $50.00
Total $700

Full device with 10 boards price breakdown :

Controller device $150.00
ASIC board $250.00 x 10
Shipment $50.00
Total $2700

The case will be similar in size to a mid-tower standard PC and you will
be able to purchase 8 additional boards if you decide to go for the entry
level machine now, sorry to inform you that, in that case, there will be
one more charge of $50.00 for shipping.

In case you decide to go ahead please provide details of your order, your
full name, address and valid phone number along with the 5 btc transfer to
1FyZ3qU54jxU5tF2KHxHmnyjkAsdWuiyFr
We will let you know when the production have actually started both via
email and our blog.

Best Regards
Asicminer team

Now why would he be refunding 5 BTC back to everyone if he still has a couple to sell?? Undecided

Anyone who gave him 5 BTC - you will never see it again. So don't hold out any hope.

NO REFUND TILL THIS VERY MOMEN

Do you mean "so far" (as opposed to "until this very moment") in American English, or did you actually JUST get your refund when you posted?

Well, ASIC miner is closing its doors http://www.reddit.com/r/Bitcoin/comments/iynpe/asicminernet_calls_it_quits_wont_sell_product_for/

they claim they just sold a batch to an investor, im gonna go ahead and call bull and say the total network hash wont increase 2.5 terahashes..

i guess we can watch block explorer and find out

LargeCoin continues to plug away quietly, and it's not a scam. For more information, http://largecoin.com.

Alright I admit it, I'm the one who bought his entire batch. But out of love for my fellow bitcoin miners and not wishing to drive away potential bitcoin users, I had decided that I will only put one machine into operation every 3 days, which is why in turn I required that they don't duplicate the machine in the next 3 years.

It could be totally true, there was a research paper from the Chinese University of Hong Kong about using Pilchard "RAM" boards for DES encryption in ECB mode back in 2004.
http://microsys6.engr.utk.edu/~bouldin/pilchard.pdf
http://www.cse.cuhk.edu.hk/~phwl/mt/public/archives/old/ceg5010/pilchard.pdf

And they probably wanted us to believe that this is the paper they used as inspiration:
http://www.ee.usyd.edu.au/people/philip.leong/UserFiles/File/papers/sha_fpl02.pdf

Problem is that this paper is pretty old, and the hardware they mention is outdated. If other people in this forum with much more modern FPGAs couldn't come up with a feasible implementation, there is no way that this could be competitive. This paper was written before GPGPUs became common.

And I couldn't find a more modern version of this Pilchard module.
