don't take it personally HashFast_CL, I'm sure you are a nice person and just want to do your job right. Your boss released you in a desperate situation. We are just a few pranked guys who lacerate everthing thats thrown in their direction. We made wrong decisions, based on false promises, resulting in a significant loss for all early believers in HashFast.
You know what, we are maybe a few pranked guys, but we surely won't lacerate if HF throws to us some sort of meaningful compensation instead of this "Wov, 500GHs!" marketing b***s***, which adds insult to financial injury. How about shipping BabyJet upgrades immediately with batch #1 BabyJets instead of shipping them later? How about shipping complete Sierra instead of bare bone motherboards for MPP? Do we have to think about those things or it is a HF marketing department job to think about some ways of improving customer relations buy acting in customers interest even if it significantly reduces HF profit from batch #1? Isn't it logical to give up some batch #1 profit to compensate their most worthy customers (we jump-started their company) after HF spectacularly screwed delivery time? As a Batch One customer, I fully understand the anxiety and frustration of watching my BTC ROI dwindle as difficulty rises. Of course ROI in fiat is an entirely different story and a source of much consolation.  500GH per second is an engineering fact, not "marketing" BS. Another engineering fact is that only a finite and very limited number of Batch One chips exist. HashFast cannot use magic or wishes to create more, so shipping extra capacity is impossible until more chips are ready. MPP chips have already been paid for and are being fabricated. Once our production line is complete, meaningful estimates for MPP shipping dates may be anticipated. While it has been a long process, we are nearing the end of the beginning! Best, -HF_CL |

Am I the only one to find this HF bragging about speed increase insulting to intelligence? @HF_CL: It is totally irrelevant if chip hashes at 300, 500 or 700 GHs. It will mine >50% of it's lifetime returns in the first 2 months or less of it's total mining life. The position of these 2 months on the timescale determine the total value of the product, so the only important thing for all of us about your product is it's shipping date. Correction: other important thing is shipping speed, since it can also mess with a few days of mining. Hashing speed is totally irrelevant, since 25% increase is worthless because it is negatively compensated at least that much when difficulty increases >25% every 11 days. I know there's no way you don't understand these simple facts, so yours "Wov, 550GHs!" makes me really offended. Do you really think you are dealing with idiots?
What i don't understand is the bragging while they only got 2 cores out of 4 to work. I know that it's easy to multiply by 2 the speed that you got with 2 cores and they may get that speed, but bragging without actually having a proof is just lame and sad. Roadstress,
Per Eduardo, all 4 Golden Nonce "cores" (dies actually) are working to produce the announced 500GH/sec speed.  Our next blog post will elaborate on the details. itod, The promised mining speed of 400GH is what HashFast's customers paid for. Exceeding that advertised minimum by a whopping 100+ GH (25%) is highly relevant to their ROI, regardless of difficulty. If we only shipped 300GH instead of 400GH, I'm sure HashFast customers would find that anything but "totally irrelevant." CIARA has tremendous logistical experience which should benefit HashFast customers by reducing shipping times to the minimum possible. http://www.ciaratech.com/product.php?id_prod=305&lang=en&id_cat1=5&id_cat2=39 CIARA ships daily in large volumes from our 14 loading docks. We have the ability to ship via all transportation modes as we are located less than 2 miles from the FEDEX, UPS and DHL hubs as well as being less than 4 miles from Montreal International Airport. Having this proximity allows CIARA shorter transit times than most agents. CIARA offers flexible shipping hours spanning from early in the morning to midnight at month or quarter ends. Whether it is during the regular day, end of month, quarter, year or simply an urgent shipment CIARA will get your shipment out. Export compliance management can be very confusing as it is constantly changing. Managing this for our customers is not a problem as it is a daily occurrence. Whether you are shipping domestically or internationally, CIARA has the logistical experts that can prepare your paperwork, guide your shipment while reducing your freight expense. Of course the sooner we ship the better, and we anticipate meeting the Dec 31 deadline for Batch 1. Best, -HF_CL |

Who cares? You're months late.
HashFast customers will be pleasantly surprised by a free 25% boost in mining speed. We anticipate shipping batch one before our deadline at the end of the month. Otherwise, refunds will be issued. |

Looks like Baby Jets will be closer to 500GH than 400GH!  https://hashfast.com/hashfast-announces-fastest-bitcoin-mining-chip-in-the-world/
HashFast Announces Fastest Bitcoin Mining Chip in the World! Posted on December 13, 2013 by Janielle Denier in Baby Jet, Blog, Development, Golden Nonce ASIC, News, Rig Assembly HALF A TERRAHASH/s (500GH/s) on a single chip. HashFast ASIC Golden Nonce- Half a Terrahash Complete bitcoin mining system as found in the BabyJet This result was achieved during the bringup process of HashFast’s GN chip and module. The engineering team are progressively testing the system, and have not yet reached the full speeds the system was designed for. We expect to see better results over the next few days. This milestone represents a breakthrough in Bitcoin mining technology and is several times faster than existing Bitcoin mining chips. We are starting volume production of mining systems now. Stay tuned for further speed results. Kind regards, Simon Barber |

Hello eldentyrell, Please update your nifty list with HashFast's confirmed info. We're using 4 9x9mm chips (18x18mm total) to produce 500GH+.  What are the die size, package type, core voltage, transistor count, operating frequency, and projected TDP of the chip?
The package is a BGA, containing a multi chip module. There are 4 dies, each 9mm x 9mm, spaced out by 5mm. The core voltage and frequency vary according to the cooling available to the chip. The chip contains a temperature sensor on die, and increases or decreases the operating voltage and frequency to maintain a target operating temperature at the die. The allows the maximum possible performance to be achieved, given the cooling that is available. In a colder environment the chip will operate at a slightly higher voltage and frequency, and return a higher hash rate than in a warm environment. Simulation runs show that the best silicon will have a TDP of 250W when operating at the name plate (nominal) 400GH/s. Worst case silicon will consume a few % more power to reach this nominal 400GH/s. Note - simulation results can be out by +/- 20%, although they typically come in high (expect lower numbers in real silicon). I'd like to write today about a small piece of why we are confident our product is better than KnCs. So today's topic: Our silicon design is superior. Both are 28nm designs, but HashFast's is far more powerful and energy-efficient. Let's look at KnC's 28nm ASIC, and some basic details as we can pull from their documentation. https://www.kncminer.com/news/news-25First let's calculate the hash rate per square millimeter of silicon. This is a measure of the efficiency of the design. Honestly, we don't need much to estimate this. The lid size for their chip is enough to make some good estimates. KnC's diagram shows their chip has a 41.2mm lid, and implies that the silicon under that lid may be between 30mm x 30mm, and 36mm x 36mm. (The additional space is needed for decoupling capacitors and such.) Let's use those two numbers as bounds for the size of the silicon under the lid. If the die(s) take up just 30x30mm of the space under the lid, then: 30x30mm = 900mm^2 100 GHash / 900 mm^2 = 0.11 GHash/mm^2 Or if the die takes up a bit more of the space under the lid, 36x36mm = 1296mm^2 100 GHash / 1296mm^2 = 0.077 GHash/mm^2 HashFast's Golden Nonce chip: I don't have to estimate the size because I work at HashFast. One 18x18mm die is able to do 400 GHash (nominal - more overclocked**) Hashing per square mm: 18x18mm = 324mm^2 400 GHash / 324mm^2 = 1.23 GHash/mm^2 Let's compare those numbers, for the high and low values for KnC's chip: 1.23 / 0.11 = 11.2 1.23 / 0.077 = 16 So HashFast's chip is between 11 and 16 times more efficient, in hashing per square mm, than KnC's chip. This has an impact on how fast we can deliver units to customers. One wafer of HashFast's chips has the same capacity as 11 to 16 wafers of KNCs. For each silicon wafer delivered by the foundry, KNC will be able to satisfy 11 to 16 times fewer customers than HashFast will be able to. You'll get your units faster once production starts from us. In addition, the HashFast chip operates much more efficiently. You get four times the hash rate for the same amount of power (250W). (Based on 250W for 100 GHash from KnC, and 250W for 400 GHash from HashFast.) Calculations such as this are a small part of why we are confident that we are delivering a quality product to our customers. We figure it's time to start sharing. Amy Woodward VP Engineering HashFast ** P.S. Simon made me put in the line about overclocking. But as per the 'warranty' thread, no one would ever do that to our beautiful chips, right?  https://hashfast.com/hashfast-announces-fastest-bitcoin-mining-chip-in-the-world/HashFast Announces Fastest Bitcoin Mining Chip in the World!

Dear Community Liaison, as people kindly explained you, we don't know what to do with your 20% speed increase of a product that was priced for a delivery 2 months ago (aka, in a 5 times more friendly mining ecosystem).
Think about shipping the MPP as soon as possible and if you want to do something useful that you can actually do, ask them to answer my case, (#449), that with legit questions is still unanswered after a week.
Dear cedivad, HashFast fully anticipates meeting the stated guaranteed delivery date of Dec 31. Otherwise, refunds will be issued. 500GH is an increase of 25% (not "20%") over the initial 400GH spec. And there may still be additional capacity yet to be unleashed! HashFast already paid for Batch 1's MPP chips and they are being manufactured at TSMC, the world's most advanced wafer fabrication plant. You may rest assured Batch 1 customers will receive their extra MPP miniboards as soon as possible. |

what is the mining interface/controller? After all the baby jet was supposed to be self contained miner.
HashFast uses a standard USB interface. Anything that runs cgminer will work as a BabyJet controller. |

I'm not sure where the " <0.5W/GH/s underclocked" claim came from.
It came from Simon himself: Chip Specs
- 28nm custom ASIC
- Power Consumption: significantly less than 1.0 W/GH at nominal clock speed
- Designed to be underclocked for greater efficiency – better than 0.5 W/GH*
- Designed to be overclocked for greater performance - better than 500GH/s**
Oh I see, thanks! That squares with the advertised specs when you factor in the rest of his post: * Real silicon power consumption may vary from simulation results by plus or minus 20%

@HashFast - 4 Dec 13 - 2:32PM ET
GN chip bringup - Power consumption: 0.14ua/MHz at 0.77volts at low speeds. That's 0.56W/GH/s. More tests happening now.
These twitter updates are great. Whoever at HF is doing these, thank you. 0.56W/GH/s does not sound very encouraging since they were advertising <0.5W/GH/s underclocked. Not sure at what speed they are testing at but it looks like consumption is +10% of what they were shooting for? HashFast_CL is doing them, though I have no idea who that is. I asked them for W/GH/s and I'm glad that they put it up today. They said they should have details on max clock speed and thermals within the next 24 h The W/GH/s is preliminary and will change when the chip runs at full speed. I'm not doing the tweets. According to Amy, Simon is posting them. I've let them know they are a very popular improvement over forum updates and blog posts. According the product page, HashFast is advertising Power Consumption at the chip: less than 0.65 W/GH/s +/- 20%
Designed to be underclocked for greater efficiency, and overclocked for greater performance* so I'm not sure where the " <0.5W/GH/s underclocked" claim came from. Follow HashFast on Twitter for all the latest exciting updates! https://twitter.com/HashFast |

At first I was going to tell you hashfast, but after seeing them delay again I have no idea....
New customers buying currently availabe hardware are not affected by the recent clarification of Batch 1/2 shipping dates. HashFast has chips in hand and is working with two independent design firms to complete a suitable substrate ASAP. Substrate design, like chip design/NRE/tape-out, is a one time ordeal/expense (unless your design is flawed ). Customers buying HashFast hardware now will in no way be (negatively) affected by the current race to complete the substrate. Best, -HF_CL Will there be any compensation for those that pre-ordered batch 1/2 babyhash without the miners protection program? All Batch 1 BabyJets include MPP. We initialized the MPP early (Oct 31) to make up for the time lost. |

Hi everybody!
Sorry for the lack of communication; I was ill and unable to liaison with the HashFast execs last week.
I'll go in to the office on Monday and see what news/updates can be shared with the forum.
Best,
-HF_CL
PS I've been reading about the new Global Work Queue. It has the potential to do for devices what stratum did for cgminer (IE keep everything topped up and minimize idle time to squeeze out every last drop of performance)!
So its near the end of the work day on the east coast. Do you have anything to share with the forum? I'm at the new office but the execs aren't here ATM. Everybody is out working furiously to get the hardware built and shipped ASAP. This is clearly a company that intends to be around for the long haul, and is in the middle of both growing and birthing pains. If I can get the printer working, that will be a small victory! Best, -HF_CL |

Just an fyi - they are saying that they are leasing out equipment with HashFast chips, yet we have no idea who this is: http://leasebit.com/Braun-1-Assalter.htmlIf you are behind this website, and have actually purchased equipment from us, please contact me personally, and I will confirm here. -John Thanks for clearing this up. I'd hate to have customers intending to buy HashFast products not get what they paid for. Does this mean he confirmed it? No, HashFast has not confirmed LeaseBit is a customer. Until LeaseBit responds to our open offer to contact John, be very careful of this potential scam. |
