Topic: [PicoStocks] 100TH/s bitcoin mine [100th] - page 82. (Read 470203 times)

Yep, someone had to make good bussines when price dropped and now is investing <- speculation...

Wow, someone bought ~1600 shares, with the last and highest trade at 0.0707 BTC. Already 77% higher than the IPO price (0.04 BTC)!

Lol

Chip production update
The wafers will be completed on 2013-05-19 (May 19th). We are negotiating the timing of packaging now.

Zmienił się raport na Picostocks, może warto również tutaj zamieścić info?

On Picostocks site report have been changed, maybe it's worth to publish it here?

1. We will discuss with FinCEN the legal aspects of bitcoin mining in US :-)
2. Dave is preparing tha data center for "cyber" attacks
3. There is no theft protection ... we will think about this
This is not planed. This would complicate the deal. There is still sufficient variability of profitability due to the unpredictable network hash rate and btc price. It is possible that the mine generates revenues that are higher that the presented optimistic scenario.
Funding is independent. Even if there would be no funds raised the project would continue as planned. The IPO* was intended mainly to test the shares as a distribution channel. However after publishing the FinCEN guidelines we believe the shares could be less risky for US miners than possession of mining equipment :-)

What are the long term plans for the 100TH security? Will the capacity be expanded? If so, what kind of share dilution will there be? Was funding for these 3 projects separate or all under the umbrella of the "100th"? With Asicminer, they have a separate company, bitfountain, that owns the majority of shares, but I believe future development and hashing power is added to the total capacity of ASICMINER. Is this project similar or are the other business activities separate ventures?

thanks

Tape out submitted.
The mask production start tomorrow with the lowest layer. Then ca. 1.5days per layer is needed and we need 31 layers => the wafers will be ready in 2 months. We actually still work on design of minor elements while lower masks are produced. We have left arrays of NADN2 cells that we can later connect to build logic with it [something like fpga hardcopy :-)]. We have approximately 2 weeks to get to the stage where the connections have to be final. After the 2 weeks we will start planning the board, work on followup logistics and talk with suppliers and manufacturers for the final devices.
We can not tell who we sell the chips to, unless the customer wants to disclose this. Any serious ASIC miner manufacturer will disclose the source of the chips. Saying that the company XXX does not have our chips does not mean they have no chips and does not stop any scams :-)

someone should make a list of potential scam ASIC companies, there are so many nowadays and everyone is talking about hundreds of Thash/s

Much like this scam has been identified as such back in Feb.

Doth not surprise me he's trying to support his fellows by lending vague support to scammy claims.

It would probably be wise to publish a list of who purchased chips because of the number of scams popping up online. They will all just be marked as scams instantly and ignored as soon as they announce their product.

I will post a report, after the design is submitted. I also wait for this impatiently :-)
Selling chips will be easier than selling hardware (less paperwork and less clients), but before we sell anything (more) we want to have precise characteristics available. This will be available end of May the soonest :-( My expectation is that in 2014 only 28nm chips (or better) will remain on the market, so timing will be also crucial (as always).

Świetne wieści. Pora napisać nowy raport na Picostocks.
Cyfry robią spore wrażenie. Gdy układy będą gotowe i sprawdzone z chęcią bym kupił trochę. Oczywiście jeśli udostępnicie dokumentację

18 wafers (more than 200TH/s). 1/2 goes for the mine. 1/4 is already sold as chips to undisclosed manufacturers. They will use them to produce hardware for customers [but who knows when this will be ready]. Rest goes for own development.

thanks for the update. how many total wafers did you order?

I don't want to promise any speed boost because after we get the chips they may not even run at the expected speed of 3.3GH/s :-) [see BFL problems]. Also we will still order mainly tt wafers (!) and only 2 ff wafers just to see if they work as expected (ordering ff wafers now for the mine would be too risky). If they work better we can use the ff wafers in a later production run => the buyers of hardware few months later could benefit from the option to lower voltage and adjust performance based on selected gh/joule. To be able to do this we need to design the chip to handle low VDD. We can not modify the chip later. But the benefits will come after the 100th-mine deployment if we ever decide to produce more chips [this depends on other chips on the market].

whoa..does that mean we're getting a 65% speed boost?!

We will try to offer hardware but this is not priority now. It is a lot of additional work.
...
Tapeout is on Wednesday. We had additional delay because we had to investigate the option to use other process corners (the foundry provides also the option to produce fast transistors (FF model)). We found little advantage of using the FF corner at or above 0.6V, but after some additional simulations we found that the chips would work very nice in the FF corner at 0.50V - 0.55V. To be able to operate at this voltage not only the hashing cores but also the IO transistors must be "tuned". We made sure the chips will work at that voltage.
Provisional estimations are below:
vdd   m   gh/s   watt   gh/J
0.60   tt   3.34   0.96   3.49
0.60   ff   8.02   3.67   2.18
0.55   ff   6.84   2.23   3.07
0.50   ff   5.51   1.38   3.99
[m: model, tt: standard, ff: fast transistors]
=> at 0.5V we get faster chips that have higher gh/joule than tt chips at 0.6V
Of course these are just simulations.
...
We understand the the most important is timing of deployment. We loos a lot of money with every day of delay. We still think start on July 1st is feasible. We selected a packaging facility that is in the same city as the foundry so we hope to have the packaged chips in house end of May. The rest is fast :-)

I really hope you release retail products and not only to Poland but at least for whole EU. Little bit of competition with Avalon would be good and we will need some manufacturer in Europe too.

That said... I might still invest for some shares.
