Yup Im out, why waste time on this when FTC is 400% profitable right now

The problem is that the on-device block RAM is insanely slow compared to GPU ram (about 10 times slower for most FPGAs). The per slice block RAM for most FPGAs is also less than 128 KB (more like 8 KB in typical cases).
Well, I'm not as familiar with GPU, but I doubt it is 10 times faster. And I believe you have been misinformed regarding the capacity as well. The Spartan-6 LX 150 used on many of the boards already built has 4.9 million bits of memory. The memory in -3 speed grade part can run at up to 320MHz Newer but similar priced Artix-7 have 13.4 million bits, with up to 509MHz in -3 grade parts. As it relates to scrypt and it's 128KB scratchpad, the core loop accesses memory sequentially in 1024-bit widths. Within an FPGA, you can have access to all 1024 bits in a single clock. While you may not be able to achieve that performance point due to other issues, 1024 bits @ 320/500MHz is nothing to sneeze at. Total block ram on the whole chip for a spartan6 lx 150 (most expensive chip) is 4824 Kb. http://www.xilinx.com/products/silicon-devices/fpga/spartan-6/lx.htmMemory bandwidth for the block RAM is about 30-60 gb/s (your numbers above) while GPU internal bus is usually around 250 gb/s on higher end cards. 7990 - http://wccftech.com/amd-radeon-hd-7990-malta-performance-benchmarks-leaked-crushes-geforce-gtx-690/576.0 GB/s bandwidth. its a high end card , but that's a high end FPGA - and can the FPGA compete with ATI productive to Scale power? not saying it can't be done just saying [Watts and Space] - is the net benefit i see. I hope we can say more about expected performance soon, though two of the primary benefits are certainly much lower operating costs and are way easier to scale up. |

I barely got any coin mining at 1 Khash all night...not so sure about this coin. Switching back to FTC
Won't get anything at 1 khash, lol. Think you mean 1 mhash(1000 k/h)? If so, than it's your pool that is the problem. Er, Mhash yes  I am actually getting a pretty decent trickle of CNC from the p2pool I was on, well see what I got. |

GPU miners are going in altcoins where not even FPGAs really exist yet (unless BlockBurner has something to say about that ), let alone ASIC devices. Bitcoin is going pro, only those with more daring and deeper pockets can mine effectively, leaving coins like Litecoin fertile ground for all manor of lower end investors that missed the Bitcoin wave. ASIC will push GPUs out of Bitcoin, but not the rest by far. GPU mining will be fine until FPGA or ASIC is simply the starting standard for new coins. |

Well, I am getting bombarded with messages! There is a little backlog for me to chew through but if you sent me something I will get back to you in the next day or two.
Overall incredible response guys, from well-wishers to the hardest core miners, we really do appreciate it. The team is off and running charting out hardware and developing our business structure. For only being about 1.5 weeks old, we have already grown tremendously.
For devs applying, frankly we have about 5x more than needed for the moment! As much as I wish I could include everyone that had interest in helping out, I simply can't. I had no expectation that we would have so many interested to be a part of this, which is both amazing to see but sad that I must turn the majority of you down for this one.
But, it is obvious that 1) There is serious passion around these boards and 2) You guys really want to be involved in a community project. So, dev applicants, though you may not be able to be on the core BlockBurner FPGA team (for now), I am thinking about doing something else. I will be getting back to all of you in time to get some feedback on this.

I am very interested , but do not want to BFL this long of wait . This is a failed company .
Our timeline in fact is shaping up quickly, though I cannot give specifics on the near future, I can say there will not be a year long wait without updates (because that is ridiculous). If everyone is still waiting a year from today for this device , I would be inclined to agree with you on our many failings. I would prob argue that graphics cards can be resold just fine unless they are damaged, while a special built FPGA for LTC mining would be a different story altogether. Not that I or anyone really care, if you buy a LTC custom FPGA I would assume you do it with a ROI within reason and resale value not included. Otherwise you have to be nuts!
Well first off, it is not a LTC custom FPGA. It is a LTC, FTC, BBQ, TBX capable FPGA and a possible incentive to think about getting merged mining implemented in the Scrypt-coin world too if you want to extend the usefulness of the device. Maybe by the time LTC, FTC, BBQ and TBX are all far too difficult for the device to effectively mine they could all be merged together and some newer ones thrown into the merge too, extending the useful lifetime of the device. -MarkM- Yes indeed, overall, just like Bitcoin ASICs are in fact SHA356 hashers that can work with a variety of altcoins, our Scrypt optimized board would work on any Litecoin derived coin. Scrypt is used beyond Litecoin as well, making this machine useful for a variety of cryptographic processing. |

Miners are not global conglomerates or corporate bankers, they are tech enthusiasts and futurists. Even if one coin were subverted that way, one of the others could feasibly replace it and simple dis-adoption would remove that OPEC like power structure like cancer. Bitcoin is more self corrective than people give it credit for. It could be true if Bitcoin itself was the only crypto in existence, but Bitcoin and Litecoin have spawned many derivative coins that all ride the same network and hardware.

I'm able to get around 360 kHash per card with moderate OC in Scrypt mining with my 7850s, could probably get that up more with some better cooling.

Iceland would be fertile ground for the first country to go full Bitcoin after their bank collapses. Their citizens don't trust banks further than they could kick them, and introduction of Bitcoin as their defacto currency would be huge!

May I know the hashing power? 10 or 20 mg/s?
It is not bitcoin.. for FPGA it should be in the KH/s, even multiple graphics cards only give you low MH/s Wrong. FPHA has nothing to do with it. It's because LTC is SCRYPT, and I am assuming the goal of the FPGA's would be to reach into MH/Sek otherwise why design them? FPGA's are likely to continue to lag behind GPU for litecoin, currently there are no products I know of that can produce in the MH/s range for a single unit. I.E a single GPU/ FPGA (even with multiple cores), and the reason to design with FPGA are numerous, I will give you two. 1. lower power consumption 2. Ebay scrap. (this works fine for individual miners, but not if you want to build and sell to the public.....) So even if I cannot match GPU:FPGA on a 1:1 basis, I can out purchase on a 1:n basis LTC difficulty is set to jump again in about 2.5 hours (62 blocks to go) and is currently skyrocketing, even to scale up and remain profitable GPUs become unviable at a point. They simply don't scale well from the massive power and cooling cost. The only FPGAs used with Scrypt so far were available Spartan units, which gave decent performance. We are out to build a device with Scrypt in mind. We will not give any numbers until there is something concrete to report. Will the FPGAs take more than a month to be completed? Is there a pre-estimation?
At this time we have no estimations, or even pre-estimations on any dates. The team is just coming together and we are still seeing what we need, but the groundwork and planning has begun in our JIRA dev site (if you are a mac/windows/linux desktop developer PM me!). We have no desire to be a shipper of vaporware or make promises we have no idea that we can keep in the end. As such, announcements will be made when we have real information. Talk is cheap in this industry, we are more interested in letting real results speak for us. It is my own personal desire to see us have a production sample in our hands within 6 months. BlockBurner is only about a week old now, so we have a ways to go before I can say anything more concrete. We are designing a ground up FPGA opposed to using off the shelf parts like FPGAs before it, so there are certainly some unknowns to overcome. I will be creating a FAQ soon with the most common questions I am getting, stay tuned! Operatr |

Target a country like Greece, their citizens are desperate for a way out of the banking system that has done nothing but mercilessly screw them all.

No one is seriously invested in it.
Wrong. Litecoin's market cap = $68,152,758 usd I know of people that hold 100,000+ coins I can't find any decent stats on LTC. Is there a site like blockchain.info, but for LTC? Here's a few good ones. We have to look at the entire picture. I predict Litecoin doing what Bitcoin did but faster as Bitcoin has already blazed ahead of it, which should foster quicker adoption. But moreso, Bitcoin will soon go beyond the reach of mere mortals and weekend traders. Mining is about to go insane with ASIC for BTC, also involving a large upfront investment to get a piece of. 2nd generation coiners have kinda missed the boat at this point unless you can jump right in with either high per Bitcoin cost or high investment in mining gear. But, there is Litecoin, a far cheaper alternative investment, and with ASIC driving GPUs and FPGAs out of Bitcoin, they will find a new home mining alternate currencies. As Bitcoin moves out of reach for average investors, attention will turn to Litecoin. Essentially Litecoin is about where Bitcoin was 2 years ago. Bitcoin made a name for cryptocurrencies ahead of it, I think the progression of the markets will go through phases as accessibility shifts. We may see the other altcoins start gaining traction as well someday. Who knows, but it will be damn interesting to see what happens now. |
