Bitstream or GTFO....  

Now seriously, on your next 16nm chip you need to do two main things, if and only IF you want to dominate the bitcoin mining business:

• Sell it on small quantities: 3-packs (no problem with markup here) or even have a sampling program (look at TI's or Microchip's program, you get the drift). TSSOP or QFNQFP versions would make you my personal heroes, like, really heroic.
• Release a GOOD, CLEAR AND INFORMATIVE SPEC. Bit-level timing, SPI commands, application notes with usual circuits for working the chip.

These two points aren't really that hard, and would show your commitment to a real decentralized, hobbyist oriented business. I just want to get my iron, solder and create my own money making machine. Is it that too much to ask?

I would assume they are releasing the board info so engis and small companies can prep designs to incorporate their 16nm chip....

16nm chip will work on 28nm boards.

"So from 1 UART connection we're able to service up to 1700 hash chips (over 20TH/s with our 28nm chip and even more with the 16nm). 16nm will work in a very similar way."

You are releasing your 28nm designs when you already have a 16nm chip out in the wild. Economically this is useless. If you wanted a decentralized Bitcoin Blockchain you would've release this last year, not now.

Really? Are you for real? Nobody will buy these chips when they are less than 1 month away from mass deploying their new 16nm chip that needs less than 0.1W/GH. Please stop with your shilling!

Dude, stop being so naïve. Brownnosing to chip vendors is nowadays the only marketable skill for non-technical people. Bitcoinorama is now back posting, go reread his story. Maybe he finally got paid by KnC?

Shill is actually a highly honorable occupation centered around getting paid by the vendor.

I am sorry, but I find this move to be FULL OF SHIT.

PLEASE STOP LYING ABOUT YOUR DECENTRALIZATION EFFORTS.

BitfFury is deeply committed to a decentralized Bitcoin Blockchain ecosystem and we want to do all we can to ensure that as many hobbyists and engineers as possible have access to the technology we have developed with the support we've had from the Bitcoin community. Therefore we have decided to release our 28nm designs under Creative Commons Attribution Share Alike 3.0 License to give you the opportunity to get familiar with the style of our latest designs.[/size]

I do applaud Bitfury for making a presence on the forum, I hope it is because they are truly committed to us "little guys". 

StringPowerBlock.pdf is probably the most interesting one. This is a block of one 250nm communicator chip and seven 28nm chips. Here you can see how the individual blocks are interconnected (differential pairs), hashing chip connections and how the StringPower design that BitFury pioneered with our first 55nm chip works.

189 chips/board x 25Gh(BF 28nm - 32GH)= 4725 Gh/s / board at 0.2 its 1kw/board, is that correct?

Fair point on Cheap hyrdo power in China eg the 3 Gorges Dam but frankly, that vast majority of overall power production production is spoken for. For most heavily industrialized countries, for just one segment - aluminum production - takes one helluva chunk. ref: http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/
"According to Alcoa, the world’s largest producer of aluminium, the best smelters use about 13 kilowatt hours (46.8 megajoules) of electrical energy to produce one kilogram of aluminium; the worldwide average is closer to 15 kWh/kg (54 MJ/kg).

Worldwide production of aluminium in 2010 was 41.4 million tonnes. Using the figures above this means that 621 billion kilowatt hours of electrical energy were used in the production of aluminium. To put that in perspective, the total world production of electrical energy was 20261 billion kilowatt hours, meaning that more than 3% of the world’s entire electrical supply went to extraction of aluminium."

Toss in the other more pressing power needs of China and you get my point.

Ja certainly a lot of low cost power will be available to local (ish) peta-farms but not as much as you think. Outside of being right next to the power plant/dam (the now closed Alcoa smelter site in Washington state comes to mind) the infra over there just does not support someone suddenly deciding to run 25-50MW much less 100MW or more without a helluva lotta prep and time/cash for it to be done.

All bitmaintech need is 100 mega watts at 1 cent that = 300 to 400 ph.

https://en.wikipedia.org/wiki/Three_Gorges_Dam   this plant can do 22,500 mega watts
