Unless we hit the "Bitcoins and Red Balloons" problem and someone sybil attacks the network to obtain a ton of fees while no one else gets them. There are some weird patterns recently in fees that are a little suspicious: http://blockchain.info/charts/transaction-feesThat may also be evidence of some kind of new form of money laundering: If you're a miner with enough hash power to claim your own blocks, you can not broadcast a bunch of transactions with large fees and give them to yourself when you announce your block. |

I assume he's talking about this: 11 + 3. DELIVERY AND QUANTITIES.
12 + (a) Guaranteed Baby Jet Delivery Dates – Batch 1. All of the 550 Baby Jet units from Hashfast’s first production batch are guaranteed for delivery by December 31, 2013. If Buyer ordered one or more units of such Baby Jets, and Hashfast does not deliver such units by that date, then Buyer may cancel the undelivered portion of the order at Buyer’s request and Hashfast will refund the payment for the units that Buyer purchased but did not receive and cancelled. This cancellation and refund is Buyer’s sole and exclusive remedy for Hashfast failing to deliver by the December 31, 2013 guaranteed delivery date. To avail itself of this remedy, Buyer must cancel the order before such unit(s) are delivered by Hashfast, and in any case before March 31, 2014.
13 + (b) Guaranteed Baby Jet Delivery Dates – Batch 2. All of the 550 Baby Jet units from Hashfast’s second production batch are guaranteed for delivery by February 28, 2014. If Buyer ordered one or more units of such Baby Jets, and Hashfast does not deliver such units by that date, then Buyer may cancel the undelivered portion of the order at Buyer’s request and Hashfast will refund the payment for the units that Buyer purchased but did not receive and cancelled. This cancellation and refund is Buyer’s sole and exclusive remedy for Hashfast failing to deliver by the February 28, 2014 guaranteed delivery date. To avail itself of this remedy, Buyer must cancel the order before such unit(s) are delivered by Hashfast, and in any case before May 28, 2014.
14 + (c) Guaranteed Sierra Delivery Dates – Batch 2. All Sierra units from Hashfast’s second production batch are guaranteed for delivery by January 31, 2014. If Buyer ordered one or more units of such Baby Jets, and Hashfast does not deliver such units by that date, then Buyer may cancel the undelivered portion of the order at Buyer’s request and Hashfast will refund the payment for the units that Buyer purchased but did not receive and cancelled. This cancellation and refund is Buyer’s sole and exclusive remedy for Hashfast failing to deliver by the January 31, 2014 guaranteed delivery date. To avail itself of this remedy, Buyer must cancel the order before such unit(s) are delivered by Hashfast, and in any case before April 4, 2014.
15 + (d) Other Delivery Dates. Except for the delivery dates described in Section 3(a)-(c) above and delivery dates explicitly guaranteed using the words “guaranteed delivery” in the order confirmation sent by Hashfast: (i) delivery dates communicated or acknowledged by Hashfast are approximate only; (ii) Hashfast shall not be liable for, nor shall Hashfast be in breach of its obligations to Buyer because of any delivery made within a reasonable time before or after the stated delivery date; and (iii) Buyer will give Hashfast written notice of failure to deliver and ten (10) days within which to cure. In any case, Buyer’s sole and exclusive remedy after such cure period or guaranteed delivery date is to cancel the affected and undelivered portions of the order, and receive a refund for the undelivered portions that were cancelled.
16 + (e) Products shall be delivered EXWORKS (Incoterms 2000) Hashfast’ manufacturing facility, or other facility as designated by Hashfast.
17 + (f) In the event Buyer contests delivery, the Buyer must request a proof of delivery from Hashfast within ten (10) days of the date of Hashfast’ invoice or guaranteed delivery date (whichever occurs first), otherwise delivery shall be deemed completed. If Buyer fails to take delivery, then Hashfast may deliver the Products in consignment at Buyer’s costs and expenses. Timely delivery requires Buyer to provide all necessary order and delivery information sufficiently prior to the agreed delivery date. Delivery may also be contingent on full payment. No order or any part thereof may be rescheduled or cancelled without Hashfast’ prior written consent except for cancellations permitted under this Section 3. I would say Batch 1 will be shipping in December and Batch 2 in January. Since HashFast has already stated that they are getting their wafers on Nov 1st, and that we have no idea if they need to be respun, and that we haven't seen any prototype boards, I would guess we're a whiles from shipping. If HashFast is doing anything intelligent, they'll be using off-the-shelf liquid cooling units from Asetek eg Corsair H110s. I think a Corsair H90 would struggle to cool 250W, though. See: http://www.guru3d.com/articles_pages/corsair_h90_review,12.htmlA 3770K at 1.3 V pulls about 160-180 W... 250 W is a lot to cool. The whole watercooling thing is moronic if you ask me, I'm hoping they use Corsair H110s so I can pull them off and mount an aircooled unit that is less prone to failure. |

at $2.4 a coin, it is very impressive.
what other real currency is valued this high?
But its peak was already a while ago Just like bitcoin, which rose to $30 and then died at $2 RIP bitcoin  |

I'd guess we won't see the 2nd batch until December at the soonest unless there are no respins and the board production goes incredibly smoothly

we're looking at massive supply deflation in the next sixth months, and a subsequent mass increase in valuation against fiat. I do not think that this is a guaranteed result by any stretch. Bitcoin has the network effect going for it, PPC does not. Strangling the supply so early on in its adoption could result in it simply being avoided. Well, I don't think it'll be another Mincoin or SC2 though because the long expanse in which PPC has been issued since its genesis was reasonably fair and the change in reward is based partially on the userbase and partially on an arbitrary algorithm released by the original designer, rather than just the latter. When the deflation isn't 100% dictated by the designer and is effectively created by the work of the userbase, I think it's a different scenario. I don't think it's a guaranteed result either, but I'm happy to mine it when I know that dumping my ASICs onto it decreases the supply of the currency more than it does for Bitcoin. We've yet to see what happens with elastic reward coins when hash rate increases exponentially. I think it's silly to call PPC "worthless" too, as it was the original PoS coin and most of the other current PoS coins are just clones of it. The same argument went for LTC and LTC has experienced more growth than I ever anticipated. |

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). Are you planning to sell units with lower binning chips for a discount? I'm guessing they're designed so you can still hash even with a large number of faulty hashing "cores". When are you guys getting your first wafers back from the fab? |

PPC network hash rate has doubled in the past few 30 days. http://bitinfocharts.com/comparison/difficulty-ppc.htmlPPC reward halves with every 16 (2^4) fold increase in hash rate of the network. If the network hash rate continues to increase at this rate, that means we'll see block reward halving within a few months. I don't think it's going to continue to do that. I think network hash rate is going to increase much faster. I plan to point my Bitfury devices to the PPC network when they arrive. The second generation of ASICs will bring with it about a 1000 fold increase in efficiency as compared to video cards. If even one fifth of that goes towards the PPC network, we're looking at massive supply deflation in the next sixth months, and a subsequent mass increase in valuation against fiat. If Sunny King foresaw this and created the reward algorithm in PPC to spur on adoption of his PoS methodology: kudos, nice idea. |

Whitepaper version 0.04 is now complete_ingsoc, will be in touch, I'll try to get an e-mail off before I have to give a presentation tomorrow morning forums will be back up soon. night guys. |
|
|
|
|
Not enough voltage, too much heat, or the card is borked

Update:
- Whitepaper 0.04 is pretty much done and has sought to trim down the technical details for readability. It hyperlinks extensively to the wiki, so that if you need more information, you can find it.
- Cunicula may be joining the team for the enhancement of coloured coins with derivatives/dividends, etc.
- Shift is focusing from technical development to actual development. I am meeting people locally who have degrees in both computer science and finance in the hunt for a lead dev.
- Going to contact exchanges soon to see if any are interested in being the go between for crowd funding, and also the premiere exchange for Netcoin.
I will double check the paper tomorrow and release it, then I will be moving full steam ahead with passing this to a lead dev and beginning the crowdfund. In the future, I will be only interacting with the project as a consultant.
As for the other Netcoin, no one cares

I suggest we form our own mining pool or use Slush Pool. BTC Guild is a very high fee pool and takes up too much TH/s on the network. Slush's Pool or BuzzDave Pool or GreaterNinja's Pool sounds good to me. I get 1% pool Fee  But in all seriousness if we formed a pool I bet we can do fees less than 2% which is typically the minimum of what other pools charge. Honestly, if I were you guys I'd mine PPC on Coinotron.com and simultaneously buy a bunch, like maybe $5k-15k USD worth It's where my ASICs are pointed right now. PPC has an algorithm for reward that causes it to shrink with increasing network hash rate... If enough ASICs switch to the PPC network, the price of PPC will probably skyrocket because the supply is contracted. Because ASICs have such massive hash rates, it's likely pretty soon that PPC reward will more than halve. PPC price in general has been going up in the past week, almost 30%. The advent of ASICs are probably what is going to most spur the adoption of this alt currency. And I'm not even hugely fond of it (I only have about 2000 PPC). But it's really easy price manipulation if you have a lot of ASIC power. edit: There's a stratum pool here, which gives less stales: https://bitcointalk.org/index.php?topic=173272.0I don't mean to encourage a super huge pump either... but from the look of things it's already been happening. There's been a 50% increase in difficulty in the past 72 hours. |

I would then assume you are just as skeptical of the other 28nm projects out there as well (KnC, Cointerra, etc.)? I think comparing a general purpose CPU and a bag of logic that does a bunch of right rotates, AND, XORs, and appends is a bit disingenuous. http://en.wikipedia.org/wiki/SHA-2#PseudocodeThe fact that Bitfury was able to produce a 55nm that hashes must be a freakin' miracle. I'm not really skeptical, as almost 1/3 of what TSMC ships out right now is on 28 nm. Which is, I believe, about the same quantity as on 55/65 nm at the current time. But I would be surprised if the ease and cost of developing at 28 nm were the same as for 55 nm. You should also keep in mind that Penryn was a die shrink of the Core 2 microarchitecture, so there was really not a lot new going on there (probably why the first tape-out was so dramatically successful).  What may really kill these chips in terms of development time is that they've selected pretty big die areas for them. At 324 mm^2, HashFast will have a huge problem if they don't meet thermal specs at 250 W as they'll be next to impossible to cool or will not meet specified hash rates. This was the same problem AMD hit early on with their Bulldozer processors, and the Bulldozer series of processors were slightly smaller than this. I would say that anyone who is claiming a 324 mm^2 chip with a target TDP of 250 W can be easily overclocked 25% should be considered suspicious. |

Looking forward to seeing how quickly the GN chips go through spins. To give everyone else here a sense of time, Intel's 45 nm Penryn 5500s did their first tape-out and wafer generation in the beginning of January 2007. The initial chips were able to boot Windows (almost unheard of luck for a first tapeout), but the Q9550 chips had many spins and revisions and were not released until November 2007. However, TSMC has been making solid progress on 28 nm yield for the past while, and I'd expect it'd be through spins in less than a year since it's no longer a bleeding edge process.

2) This is a variant of the above that embraces the enemy instead of fighting it. Implement (1) with reals as cl_double which is supported in OpenCL by NVidia cards but not by AMD cards. Then short AMD stock and go long NVDA for additiona gains. I'm pretty sure this isn't true, cl_double is called in the example source code bundled with AMD's APP SDK The difference in IEEE 754 implementation between nVidia and AMD GPUs is that nVidia tends to be congruent with the results that x86/x64 processors spit out, while AMD's are not because the FP precision is less accurate. But as far as I know if you can do it in the FPUs and it's invertible, you can do it in integer logic too. Whether the FPU operations would hold an advantage in that case, I do not know. |

see: http://en.wikipedia.org/wiki/Floating-pointYou need invertible logic based on integers or bit vectors in order to perform cryptography, because you can't be losing or corrupting data among operations. For instance, the extensive use of the easily invertible logic operation XOR as an additive cipher. |
