I think this list encourages fraud.
There are only two companies in your list that have actually shipped:
BlackArrow and BitFountain.
The others:
KNCMiner - science fiction story, they have not shipped anything they do not even have pictures of their products.
t13hydra, terrahash, ryepdx, burnin - rely on avalon ASICs which have not yet been produced.
Butterfly labs - have taken orders of millions of dollars, have not shipped in 1 year, most likely a fraud.
Our company has tried to purchase 30000 IC from Avalon. The law in China is to sign a contract to purchase the merchandise. We asked them for this and they gave us a bogus address in Beijing and confessed that they do not have a company. For this reason I would be very careful regarding the Avalon ASICs.
You're right, BlackArrow. I'm also concerned of Avalon chips actually shipping or not. I guess wi will find out soon enough. On the other hand, why don't you provide ASICs? I have found a book dated baxk to 2002 on how ro build ASICs for SHA-256 for security applications. If i would have a good supplier for the chips, i would shurely not provide group buy for some phantom chips tgat are not even in production yet. I know TSMC will provide them, but will Avalon forward them to us? Or at least order them... Let's do something here. What would it take to ahve asics? 6-7 months? What does it taje to build LTC asics? FPGA and a piece of DDR3 memory? Let's do it.
Thank you, FCTaiChi for the list. At least i know where i stand. I will also be providing lead time as soon as i have the Klondike final design and some money arrangements with the factory.
