Topic: 0.19 J/GH - CoinBau looks for investors in German mining technology - page 6. (Read 22388 times)

So.. $1/GH/s production cost or expected retail cost?

Hello all,

the development of the miners is done, so we can and will do tape-out as soon as we have collected the required money. As I've already mentioned, we are open for discussions about selling hardware. But these discussions are only possible with potential investors since we cannot start production without the necessary capital.
Though our concrete production costs are business internal data we can state, the GH/s will cost less than $1 in production.

Once more for all who are interested in investment or our hardware: do not hesitate to contact us via email: [email protected]
There we will be able to provide you more information or discuss your requests.
 
By the way, it is hard to talk about ASICs without the word 'tape-out' 

Best regards,
Markus

my dear mister markus, i would be interested in purchasing some of your asic boards . do not underestimate the market of the masses . orientating yourself torwards only your personal farm would be , at this point , a bad idea since you have alot of competition that has private farms for years now. the real money is in selling your miners at a competitive price on the market . i would love to see a video product presentation and a way to purchase your miners directly from your site. thank you .

I would be interested how high your initial hardware costs are? Your W/Gh/s ratio sounds good but if they cost 2$/gh/s to manufacture it would be worthless..

Wow, a company like Spondoolies-Tech in my neighbourhood!

Seems legit, but caveat emptor as always. Lots of risks involved.

They seem to avoid the high power costs in germany by moving the miners to foreign datacenters (they used one in iceland for their 1st-gen miners).

I'm interested. 

When is the tape out?

The words "tape out" should be banned from this forum... 

Hello all,

There have been some questions concerning our technology and why we are able to realize a power efficiency others can't. It's time to answer them:

Our hashing core is a fully pipelined architecture whereas our key differentiator is a very area efficient custom pipeline implementation which we developed within the last 6 months based on a so called cell based design approach. We combined standard cells with custom optimized complex cells which save area and power.
Our high density core enabled us to realize much more hashing cores on the same silicon area, running at quite low frequencies. The low performance requirements of a single core allow us to apply an ultra-low supply voltage, which is much lower than the standard at this GLOBALFOUNDRIES 28nm process node. Therefore we optimized and re-characterized our in-house standard cell library for such low supply voltages. To ensure that this will work first-time right, we developed the complete concept of this ultra-low voltage design in close cooperation with the GLOBALFOUNDRIES design enablement team here in Dresden, which has detailed knowledge of the selected 28nm technology produced here in Dresden too.
Our unique design achieves in nominal mode 1.4 GH/mm² and 0.19 J/GH. However, similar to other hardware providers, we can change the frequency of the hashing cores in a high performance mode realizing 2.1 GH/mm² at an energy consumption of about 0.29 J/GH.

If there are any questions to be answered, do not hestitate to ask.

Best regards,
Markus

Just had a look at your investment concept. Looks very interesting!
Could you share some more technical information about how you can reach 0.19 J/GH, while existing 28nm ASIC are far away from that?
Which GH/mm2 do you have at this efficiency?

nice interested like old one . maybe you need some electricity and power supply unit
for handle thats  all.

Hello,

Due to the noise the miners cause and the energy they consume and which must be cooled we do not expect them to be used in normal households. Instead, in future we expect Bitcoin miners to run in datacenters. This was the base of our CoinBau project: running our Bitcoin miners in datacenters and still offering everybody the chance to participate.
However, we are also open to discussions with potential investors concerning hardware sale or cloud hashing opportunities.

Best regards,
Markus

they doesn't seems to understand the open way as well as the decentralized point of bitcoin...

So this is not a Hardware announcement, but a chance to have a stake in your company?

Ugh, I thought Bitcoin and all facets of it were supposed to be decentralized.  Now instead of owning and running the miners, we "get a chance to own a shares of the miners they'll sell to the Bitcoin sharks running data centers".

Any chance, you'll ever have resellers for these Wolfblood cards or Wolfcave miners for the hobby miners at home?

How much for a single card?

Hello RoadStress and all interested,

of course you are right, we did not have only the two cases we sold. A few are left and we took some time to make a movie. See it under following link (I cannot post a movie here direclty):

Here is a miner running:

And here the printout of the cgminer running in the case:

And finally a screenshot of Slush's pool (older screenshot from different account):

Why not show us one gen1 unit running too? I can't believe you only had those 2 units.

Hello jimmothy,

we sold two of our miners to Marc Coumans and MAT about 3 months ago in the context of negotiations with them.

However, the miners were developed and produced by us. As you can see on the picture there is our ASICrising logo on the board. Here is an image of the testboard which we used to test the first samples of our chips:

Mining Asic Technologies?

Looks like a nice design. I will happily test a unit.

Hello all,

we know 0.19 J/GH are hard to believe and it is true, concerning our second generation we only have simulation results. For those of you, familiar with hardware design:
we performed a post-Place&Route SDF-annotated simulation of the computation of 500 random hashes of our core. These simulations are pretty close to reality and 500 hash computations are sufficient for a realistic mean power value. The power analysis was performed on the related VCD dump.

Concerning our generation 1 miners:
We do not have any problems showing them hashing. For instance, find a screenshot of one of our miners running at Slush's pool on the following link:
https://asicrising.de/miners-use-case/

We also have a video of one of our gen 1 miners in the lab:

And here some images of our hardware:
