Title: Crowd funded ASIC miner device Post by: bitfreak91 on March 31, 2013, 11:24:07 PM I'm starting a new topic on this (old) theme to ask you guys if you think you see the possibility of starting a crowd funded ASIC miner project.
My proposal is to start is for me to startup new company funded by you, the people interested in buying such a device. The things can be arranged legally so that I would not be able to access the funds (or be able to access them and risking extortion charges) of this company without your permission (and this could be done with a voting system by signing messages from a bitcoin address). The profit that I get if the device will be a success can be proportional to some variables like: the price of the final product, delivery time, performance, power efficiency etc. About myself: I have electronics background. I hold now an engineer position where I develop HDL code and design PCBs. I discovered the bitcoin three months ago and started to make my own FPGA mining rig with some FPGAs that I had at home, so the algorithm it is well known by me. The project was a success: 20GHash/s and 1,2kW consumption. So, anybody interested? Opinions? Title: Re: Crowd funded ASIC miner device Post by: SebastianJu on March 31, 2013, 11:27:58 PM I think its a bit late trying to develop an asic from the start. But if you want to try you first would need to provide data to ensure youre a real person and so on. Otherwise people wont invest into an anonymous user with 8 posts on the forum.

But if you want to try you first would need to provide data to ensure youre a real person and so on. Otherwise people wont invest into an anonymous user with 8 posts on the forum. It is impossible to not reveal my identity and do the things as I proposed. For the moment we are just talking if it is possible my proposal. The future is very uncertain so I don't know if it is too late, that's up to you. I estimate that 9 months to one year is needed to manufacture such a device. If by that time some ASIC miner "providers" don't deliver then it's a good idea to do this project. Title: Re: Crowd funded ASIC miner device Post by: tbd on April 01, 2013, 12:42:37 AM Leaving out building the miner, what do you think of developing the ASIC and selling the chips? Should be faster time to market, and relatively straightforward if you've already developed your own SHA256 core.

With as many preorders failing to ship and other issues, I don't think any other company is ever going to be able to take preorders or crowd funding. I think, as a community, we've been burned enough times. For a serious suggestion, start this company and go as far as you can go without taking anyone else's money. If you show that you've put in your own money and time, people will be much more willing to buy-in in the future. I suggest you get some designs going, get a quote from someone (and release the details, such as the company, price and delivery schedule). After you've done all this and have mountains of work to show, then you can come back and ask for funding. In the meantime, on tribute back to the forums and community by releasing details about your FPGAs and mining operations. If we can't trust you to share info like this, what makes you think we'll trust you with our money? Title: Re: Crowd funded ASIC miner device Post by: bitfreak91 on April 01, 2013, 02:29:22 AM @tbd: really I optimized the existing open source code to be able to squeeze two fully unrolled SHA256d cores in one big FPGA. About the ASIC: the chip is the expensive and the most time consuming part of the project and as I propose that the public fund the project I think is miners what they want and not chips.
@witherworth: there is no company. With me everything must start from zero as that is exactly what I have in terms of money. I know that the community lost money and hopes as many failed to keep their promises but I cannot do anything without your financial support. And also any technical support will be welcomed. Here is one of the two rigs: under each heatsink there is one Virtex 6. The green PCB next to each heatsink is a power supply with 25A@1V for the FPGA core. One level below the top you can see a Digilent Nexys3 board. That board acts as a remote (over TCP) multiple serial port. Hope you enjoy. http://i47.tinypic.com/2rfubf4.jpg Title: Re: Crowd funded ASIC miner device Post by: jubalix on April 01, 2013, 02:33:50 AM I'm starting a new topic on this (old) theme to ask you guys if you think you see the possibility of starting a crowd funded ASIC miner project.

If you could make a FPGA LTC miner now that would be something I may invest in Title: Re: Crowd funded ASIC miner device Post by: bitfreak91 on April 01, 2013, 02:39:59 AM jubalix: you wouldn't. I realised that the FPGAs that I have can give 150-200 kHash/s for LTC and that is a 3000$ FPGA.
Title: Re: Crowd funded ASIC miner device Post by: tbd on April 01, 2013, 03:43:06 AM Ultimately, yes, people would like devices and not chips. However, there have been some challenges and many apparent scams of companies promising to deliver said devices, so the community is understandably wary. I think getting funding would be difficult.
Another option would be to get funding from a smaller number of investors/partners for the chip development. There's clearly a demand for chips, both for a small ASIC device (https://bitcointalk.org/index.php?topic=161715.0 (https://bitcointalk.org/index.php?topic=161715.0)) and others interested in bulk purchases (https://bitcointalk.org/index.php?topic=162613.0 (https://bitcointalk.org/index.php?topic=162613.0), https://bitcointalk.org/index.php?topic=159257.0 (https://bitcointalk.org/index.php?topic=159257.0)). You can consider me part of this group. Title: Re: Crowd funded ASIC miner device Post by: bitfreak91 on April 01, 2013, 11:28:34 AM Ultimately, yes, people would like devices and not chips.

You can consider me part of this group. I see people are desperate to buy these chips/miners these days. It's because we are in the days where difficulty is relatively low. As I proposed there is one year needed for this project to have a consumer device and by that time difficulty will be very high. Unlike ASIC-based miner manufacturers who forget to mention that difficulty goes very high when a lot of ASIC miners enter the bitcoin network, I am warning everybody about this fact. Maybe from this point of view the perfect investor/buyer would be the category of people who own a moderate to high amount of BTC: they will initially fund this project and this will attract a lot of more people who are not a part of this category. This way more and more people will have access to ASIC based miner and the BTC will gain strength. Also the competition would learn a lesson (hopefully ASIC monopoly/oligopoly would go down) and stop selling their ASIC-based miner at these prohibitive prices.

In my proposal the buyers/investors have powers to take decisions if the project should go on at any point, or if strategy should be changed (in case performance is not considered satisfactory). There is somebody selling ASICs nowadays and he started from selling FPGA-based devices. I think it is a good point to start and you can add to that a lot of time that I can dedicate to this project and people like you giving advices and making decisions so that things finish good for everybody. Title: Re: Crowd funded ASIC miner device Post by: ShadesOfMarble on April 01, 2013, 02:26:12 PM What about using existing chips? I.e. Avalon.

I can imagine that, since the SHA256 algorith used in bitcoin is pretty well defined, that pooping out RTLs won't be very hard. I think that the functional design cannot become much more optimized than it is now. The only place where you will be able to compete is at the physical design stage. Title: Re: Crowd funded ASIC miner device Post by: aTg on April 01, 2013, 03:41:31 PM You mean those PCBs work with Virtex6? Because we can not see a photo of the FPGA without heatsink and a photo of hashing on PC?

I think that the functional design cannot become much more optimized than it is now. The only place where you will be able to compete is at the physical design stage. You are right about that, physical optimization will bring such an ASIC to a better performance vs. actual miners. But that is true only when using the same node as the other manufacturer (I consider Avalon the only at this moment!). In this project we can use smaller technology node, and as more people fund this project the better will be the ASIC. You can have a lot of advantages over the current market offer: small price, miner performance, eliminate the possibility of the manufacturer mining in the backyard etc. What other proposal can be better than this when I have no money to do this project? OK, maybe another person with an ASIC background, but the funding scheme is good I think. Title: Re: Crowd funded ASIC miner device Post by: bitfreak91 on April 01, 2013, 04:13:24 PM What about using existing chips? I.e. Avalon. For the moment they are the best public solution in the bitcoin network. But they can be taken out of the game soon if they don't come up with a better solution. Maybe this is a strategy of theirs: to start selling chips using old technology and then giving better solutions when the market is hungry again.

OK, maybe another person with an ASIC background, but the funding scheme is good I think. This is what i actually mean by physical design. The only way to get better than competition is to win on the physical part, no matter the node. Everyone will converge to current node technology so this win will decrease in the future. In a year other ASICS will be on the market baked with smaller masks. You will need to make sure now that you will be on top then because otherwise your (or in this case, our) investment will go down the drain. This is why i'm very sceptical about crowd funding someone who can't guarantee a certain product in a year. This project looks way too risky unless you already have a complete plan on what you need to achieve in your product a year from now. Title: Re: Crowd funded ASIC miner device Post by: toffoo on April 01, 2013, 05:57:44 PM I think you could argue that ASICMINER (https://bitcointalk.org/index.php?topic=99497.0) was "crowdfunded", and successful, so there you go. Best of luck with the project.

Frankly, i doubt it will work to have 25A @ 1V over a cable connection for a device with high speed switching. Also the 'power supply boards' look for me like some random surplus boards.

I will not post anymore photo. Believe what you want but I will give you technical details. The green board is capable of delivering 30A and because of those cable that you mention the voltage that reaches the FPGAs is 0.90-0.91 V (read using the JTAG). So because of those cables and high current voltage drops but even so the FPGAs work stable. Yes I know, the minimum voltage specified in the FPGA's documentation is 0.95V but they are still stable at 0.90V. About the high speed switching again there is no problem: the FPGA board has it's own capacitors for DC filtering. If you have EE background/knowledge I guess you understand all this.

And the were only for less that the half current. Not to talk about the inductance of the power cable. And in combinations with the 2 high current switching devices it would give the funniest results rather than a stable power supply. And then just for curiosity, how do you read the voltage level over jtag? |
