61  Economy / Securities / Re: ASICMINER: Entering the Future of ASIC Mining by Inventing It on: July 29, 2014, 06:50:26 AM
To dear shareholders:

We indeed had a hard time starting from the end of 2013. The BE200 performance was inferior than expected, and our prediction for the capacity of OEM producers and the individual mining market was a big miss. However, we had not stopped our work on designing our own products and finding proper farms after our chips passed the tests. Meantime we had tried many cooperations with OEMs (premium+balance payment, chip franchising) but the overall improvement on volume was not significant. Now the new hardware solution matures and we got the resources on deploying, we can turn the newly produced chips to the market where the highest margin is.

There are some guesses about our integrity also starting from the end of 2013. We would like to emphasize the following:

1. There are no umbrella companies from ASICMiner. There are indeed some unsolved conflict of interests on someone investing both on ASICMiner and other chip manufacturers, but ASICMiner did not offer any information other than what it is supposed to do, for example, holding board member meetings.

2. ASICMiner has not participated in its share market in any means.

Update

1. Due to the relatively lower interest from individual miners as well as OEM producers, the self mining has re-started from middle of July. We had gain access of cheap electricity and high power capacity. We hope to regain the average hashrate percentage similar to 2013 with this generation of chips.

2. The price rockminer gets is not the sales price. It's the premium of franchising. We gain the part of profits after the devices begin to generate revenue like the franchising of devices. The sales price of chips stay a relatively high margin because our option of building our own devices and sell/deploy is always wide open.

3. We announce the sales of our own devices. We would arrange an offline meeting in Shenzhen first to share more information. We will post the English version of it on the meetup sub-board.

We confirm the partnership between Eden.

We also confirm that Eden purchased a large quantity of BE200 from us.

What makes you think that's a scam?  Looks like a real piece of hardware built off of a specific design AM published a month or so ago as open source...  Remember?  The sexy one with the amazing heatsink design that everyone wanted just for looks.  Hell... I want one just to put on a shelf, fuck if it makes ROI!


this their official site: http://www.edentech.org.cn/

Do you think a normal commercial company would use a domain (org.cn) like this?

Why don't they show us some videos rather than only ONE blurry and small photo?

Besides, I think you might agree that PRE-order is almost means a SCAM in this industry.

btw, I have some shares of AM. That's to say, if this company do exists and is using chips from AM, it will be a good news for us all.
The sales of this company said the device was desinged by AM, they just sell it.
He also said FC will approve it tomorrow, just waiting.
Their devices are based on BE200 X-24 design. And they indeed have collaboration to us and bought a large number of BE200 chips.

We have been in close partnership with allied-control from the last year.
67  Bitcoin / Hardware / Re: btcgarden-AM-v1 sold out! New coming will be 21st June! on: June 17, 2014, 04:21:47 AM
did friedcat or somebody from AM confirmed that they are legit?
suddenly sold out, but no one received their miner?
We confirm that they had placed a large order of BE200 chips. We also confirm that their miners are real.
68  Bitcoin / Hardware / Re: The Open Source Block Erupter Project on: June 14, 2014, 05:25:07 AM
Friedcat, any news regarding overclocking/undervolting?
300MHz at 0.78V works fine (need to change the 3kOhm resistors on BOM list to 3.6kOhm resistors).

Undervolting on this design is not effective as expected because as voltage gets down the efficiency of TPS53355 also decreases. Changing to a more dedicated DC/DC solution for lower voltage is recommended.
69  Bitcoin / Hardware / Re: The Open Source Block Erupter Project on: June 14, 2014, 05:18:27 AM
Friedcat,

Regarding the design for the new cube, will each boards of the cube require a power supply and Ethernet connection? Will the cubes need a stratum proxy to operate like your previous builds or are you updating the mining software?
For power supply: we are going to open source the PSU adapter for 4*2*6pin power sockets.

For ethernet: we are going to open source the ethernect controller based on microchip PIC-32 MCU with a built-in stratum proxy. Each controller can drive as many as 32 boards (8 devices). Remember that since the boards are chained in a string instead of connected to the controller separately, raspberry-pi or PC with limited IO ports would also do the job.

The CAD of the mechanical design for X24 has been put in the repo:

Suggestions, modifications and brand new designs are all welcome.
71  Bitcoin / Hardware / Re: The Open Source Block Erupter Project on: June 10, 2014, 10:46:32 AM
My god it's beautiful.

Where do we buy them??

Also how many chips @ 192gh?
You can purchase chips and make this devices of your own.

You can also buy from our customers who are going to produce according to this open source X24 design.

Each board has 24 chips and hashes at 192gh at this setting. So the total is 192*4=768gh. The hash speed
can be got higher or lower according to your voltage.

Maybe you should point out in the original post that the whole miner hashes at 768 GH/s and the single boards hash at 192 GH/s, each. One may be led to think that each chip only performed at 2 GH/s otherwise - which would be quite low.
Good work apart from that, it is a remarkable strategy to open up the designs and let potential customers/resellers produce their own miners. Also, the increase in communication over the last few days is very much appreciated!
Fixed. Sorry.
72  Bitcoin / Hardware / Re: The Open Source Block Erupter Project on: June 10, 2014, 08:48:02 AM
It's not the cube.

When we release source of BE100 based cubes there might be some contributors who can do BE200 based cubes for us.

74  Bitcoin / Hardware / Re: The Open Source Block Erupter Project on: June 10, 2014, 07:59:38 AM
We had AM_BE200_X24 boards sampled and tested. We also sampled the compatible heatsinks and supporting structures for them. It hashes at 768GH (each board 192GH) with 0.85-0.92W/G (PSU loss excluded). Power draws on higher/lower hashrate with higher/lower voltage is under testing. The design files of heatsinks/structures are going to be released a little later.



It should be emphasized that QUAD and X32 are also sampled and well tested before X24.
75  Bitcoin / Hardware / Re: The Open Source Block Erupter Project on: June 08, 2014, 10:43:31 AM
Any chance the chips might be open source too? Wink

Yes. But there are no written plans in the near term yet.

Also it's much harder than making a piece of software open source, because the whole flow to generate GDS has tons of manual operations and very fab and technology node specific.

Please don't do this in the near future Cheesy
On a serious note: I'm curious, though, how would this profit AM?
Whenever open-source or not doesn't make difference in AM profits, both immediate and potential, we will do.

Update
1) We would like to let the project run by contributors. Please mail to jason@bitquan.com to discuss details of pull requests. And if you would like to help us by being our project manager who could maintain both this thread and github repos, please also apply by mailing to jason@bitquan.com so that we could give you payments covering your time and opportunity cost.

2) Our support for contributors besides direct reward are twofold. First, we offer sample chips to the contributors. Second, we are able to manufacture sample boards and system according to the contributors' designs. The average time of making PCB is three working days, while SMT takes only one working day.

3) We offer Bitcoin rewards to contributors who submit significant improvements or new designs. And when the de-facto core developer team emerges, we make it official in the form of continuing salary.

4) The next gen chips, BE300, are likely to be compatible with BE200 with respect to pinouts and package. Therefore all efforts on BE200 based designs are always useful in the long term.

https://github.com/blockerupter

We start this project to improve the design of Bitcoin mining devices powered by ASICMiner chips. It also aims to tackle the technical challenges of Bitcoin mining in general. We hope that with the help of the community we can keep the project active and successful.

The initial submissions consist of our own reference designs for BE200 chips. They contain hardware, firmware and software, and we had them produced and tested. They can be directly used for mass production. Contributions in forms of patches, forks and brand new designs, are all welcome.

We would like to see the project evolve and attract more and more able engineers. Thus we are in preparation of rewarding contributors and would like to be the sponsor of the future core developer team in the long term.

Brief Answers to Shareholder Questions

First of all, we would like to explain the situation we had in this May. The sales of chips mainly happened before May, while the ramp-up speed of chip sales slowed down mainly because of the lack of flexible whole-device solutions (having features of easy transportation, widely available components, etc) from our customers (device producers). As dedicated projects on improving the design of BE200-based devices we believe we will see much better sales because the room for hash rate growth is still huge and our cost in terms of $/G is highly competitive.

The other point we would like to address is that we are not cooperating with any mining device producers other than in the forms of simple buyer-seller relationship. Nor we hold shares of any other device producers. Our pricing strategy was discussed in the board before, which targets low margin large quantity instead of high margin small quantity because: 1) If both device producers and miners can have real profit after risk premium we will develop reliable consumer of chips in the long time. 2) It alleviates the problem of many potential purchasers waste time waiting for future price adjustments. 3) Higher quantity of orders in this generation leads to much more support from the fab with respect to all future generations of chips.

1) On the Balance Sheet, approximately how many chips does the current Inventory (Products + Materials + Masks) represent?
A little less than 60P of wafers, most of which are on their final stages of production. The materials consist mainly of lead frames for packaging. The mask is re-usable for years if there are continuing demands for the corresponding wafers.

2) How many months of inventory do you estimate that represents?
Depending on the Bitcoin price. Under this price we expect it to be 1-1.5.

3) On the Cash Flow there was significant expenses for gen3 production (~6mil USD). Does that represent the bulk of gen3 expenses, or are the expenses for gen3 going to continue (additional wafer batches ordered, etc.)?
It represent the order we already placed and paid for. There still are forecast plans for June we haven't paid for. They may be cancelled or delayed to later months according to how fast customers can turn Bitcoin chips to hashing power.

4) When will dividends start, and how frequently will they occur?
When the cash-flow becomes positive. After we decide to put significant quantity of chips on ASICMiner owned farms it should be per week. Before that, per month.

5) What is the status of gen 3.1 (shipping to customers, I think?)? How much does it help with energy usage -- do we have final chip performance numbers yet?
All shipped chips are gen 3.0 ones. What we had chosen for 3.1 helps with energy usage at 10% range and has some performance degrades. The final chip performance number is about 0.7W/G at 0.78V and 320MHz. Below that voltage we have less power draw and less speed.

6) What is the progress on gen4?
It is 28nm and has two major improvements: the first one is to fix the design errors we had with 40nm (which made our silicon data two times worse than simulated data). We believe that 0.35W/G at rated speed of 400MHz would be achievable in 40nm if no mistakes were made before. The second one is the technology improvement from 40nm to 28nm in terms of density, speed and power.

We are on the stage of evaluating the final design choices by running the physical design flow on different settings.

7) What is the status of self mining? What is the rollout schedule for the data centers?

8 ) What is the status of franchising partners? When can we expect to see income from them?
We will report the more detailed status to the board first. The short answer is that deploying and financing is easy while getting cheap electricity and proper device solution takes time. When we have farms running we can update the related information with real time hash rate.

9) Can you please clarify this sentence from 21st April : "The dividend schedule will be aggressive, as AM will not require large sums of retained capital." < is this still actual, or meanwhile something changed?
It is still actual. The condition in May is not a part of the plan. When we were forecasted permissively about this summer's production power of the fab, we ordered as many wafers as we could to prevent the bottleneck with wafer production.

10) What is the average selling price of AM gen3 chips (price per Gh/s)?
About 0.5$/G for sold chips.

11) What is that ~4M CNY in financial report/expenses at exchange?
Exchanged to USD.

12) What is the cash flow ratio between the amount of Chips Fabricated and the percentage of the batch that is dedicated to cost.
There are no orders dedicated to cost in the short time. So it's 1:0.

13) What is the Break Even Point of this batch of Chips?
Although the cost of making could be estimated by companies with experience on fabricating chips of high-end technology nodes, we
would rather retain the accurate price per chip from the public.

14) What is the estimated conversion time from chip sales to dividends?
The conversion time itself is fast and should not be the main stagnation of the time frame.

15) Will the funds from future Gen 3 chips be used to fund Gen 4 chips or distributed as a dividend, and what relative percentage of income will be retained for Gen 4?
Both. 1/3 as forecasted.

16) Previously our Asicminer farm was mining bitcoins and distributing a weekly dividend, will Asicminer update its present hash rate in the mining farms to account for current difficulty changes and to procure a secondary supply of Bitcoins to adapt for rapid changes in Bitcoin prices?
Yes. But that should be when we replace the farm with BE200 based devices, otherwise it is no point considering the 0.12-0.15$/kwh electricity price we get for our old farms.

17) What ever happened to the dedicated PR person and should AM make a website for distributors and for Chip inquiries?

18) Can we please get weekly, bi-weekly or monthly updates about progress, plans, sales etc. for preventing FUD in this thread?

19) Can you please communicate more clearly/frequently with shareholders?
When we are sure we get a good solution for the lack of communication we will announce.

20) What are the future plans and visions of Asicminer?
There will be at least two generations ahead. If future Bitcoin market cap allows there can be more. As we are keeping the chip design capability to grow with state-of-the-art technology as well as good channels with fabrication we can be flexible in terms of business mode be it chip-based or device-based.
80  Bitcoin / Hardware / Re: [ANN]ASICMiner Publicly Looking for Potential Customers/Partners for New Chips on: May 30, 2014, 04:00:29 PM
Some questions...

What is the behaviour if task address is changed while the chip is busy hashing?

What about when address 44 is changed?

How is nonce_mask to be interpreted?

Is there any safeguard against a race clearing r_ready after reading nonce(s)?
For example, the order of events:
  • Host reads nonce from chip
  • Chip finds new nonce
  • Host clears r_ready

1) 2) When the chip is busy hashing the values in task addresses (including 44) cannot be changed.

3) Each 1 in the nonce_mask indicates a nonce for the current job. If the number of nonces exceeds 4, the first ones will be dropped.

4) There aren't safeguards.

For 1) and 2) we suggest a higher SPI clock for better efficiency. Using the difficulty setting larger than 1 could alleviate most hashrate losses caused by 3) and 4).
Hmm, is there any way to tell the chip to abort processing a work then?
Or we just need to wait it out?
The soft reset can be triggered no matter if the chip is working or not. After that you need to reconfigure the PLL though, which will take about 0.2ms.
