It's a great chip but I think AM's chip easily on par even though was a "failure". - 1 year later...

To date AM has never made an amazing chip...they just had chips en masse first. The huge divs were because they were early and sold over priced hardware. Sorry to sound negative, but I just do not get why you guys think AM is so amazing. Maybe gen 4 will be a killer, but competition these days are no joke.

Just because it was made 9 months later means it's somehow an inferior chip?

AM's chip basically what I'd expect a Bitfury 40nm chip to be like. (had they not scrapped it)
862  Economy / Securities / Re: ASICMINER: Entering the Future of ASIC Mining by Inventing It on: October 22, 2014, 11:09:26 PM
When taking (pre)orders, you can generally bet against vendor claims for rather obvious reasons. Bitfury however is one of the few exceptions so far, delivering their asics pretty much on target (what was it, one day late?) and on spec (also in a different league than the competition, outclassing 28nm competitors with a 55nm design).

Nope even Bitfury missed their estimated specs. Their first chip was supposed to reach 5 gh/s and couldn't even go past 3 gh/s. It's a great chip but I think AM's chip easily on par even though was a "failure".

Bitfurys Rev.1 chip is 14 sq mm so they get ~4000 chips per 300mm wafer.  The chips would need be underclocked to ~1.8 gh/s to achieve 0.75 j/gh at the wall so they would get ~7.2 TH/s per wafer.

In comparison AM get's ~23.5 TH/s per wafer at 0.75 j/gh. (It was supposed to be 40 TH/s at 12.8 gh/s per chip)

Bitfury probably cannot even produce 55nm hardware for the price AM is selling it for.

Quote
They got their money from VCs and only released this information long after securing the funding. They have very little incentive to lie or even exaggerate.  If it where a bluff intended to scare competition, it would be too late to have a meaningful impact.

That's actually not true at all. They release their roadmap on Sep 15 and announced that they secured the $20m investment on Oct 9. It was clearly a strategic move.

They will need to make massive improvements to their design if they expect 0.2 j/gh without it being ridiculously expensive.

Show me where Bitfury announced a 40 or 20nm design, specs and timetable and then blew it.

Surely you can imagine how it might be beneficial to not disclose how many designs you've scrapped to the public/potential investors right?

Quote
Out of passing curiosity, feel free to point out where the CEO of a competitor made that claim, but I dont even see how thats relevant.

List of recent failures:
- Still didn't TO their custom UMC 40nm effort (AFAIK, unconfirmed)
- Scrapped big 28nm ASIC on Thermals. They got burnt from big ASICs and keeping the small ASICs design approach.
- Scrapped 20nm custom ASIC effort. "Too complicated and takes too much time". Straight from the horse mouth.
- Starting again a fully custom 28nm ASIC

Hashnest sells GHS at 0.001125 BTC.

If PBM can´t cover the costs at .0016, then how do you guys figure Hashnest does it?

Or are they a scam as well ?

You can verify it's not a scam via the blockchain: https://blockchain.info/tx/ea82419ded154267803bee5649101b50ff92fe2ce162c307ae123e938b797ca2

You might have to enable scripts and coinbase to see that they sign each block with "Mined by AntPool".

When you include fees (~$0.13/kwh) hashnest is not really such a great deal. If you mined for 3 months the fees alone would be ~$0.3/GH.

Hashnest is run by Bitmain who manufactures the hardware and has been mining with it for months. They know $0.13/kwh is no longer competitive which is why they are now selling cloudmining.

Wait are you saying that address its pbminings proof?

No it's Hashnests proof.

Hashnets = Bitmain = Antpool.

Keep dreaming Jimmy. Bitfury already manages 0.62J/GH at the wall on 55nm with their very first design. And it can do 0.5J/GH when underclocked. There never was a failed 40, 28 let alone 20nm BF design.

How do you know there wasn't a failed 40,28 and 20nm design? Do you have better insider knowledge than the CEO of SPtech who is in bed with Bitfury?

Their first chip is a perfect example of how they will overclock it until they need to underclock.

I'm willing to bet they still haven't underclocked their gen1 hardware because it doesn't make sense financially with their ultra cheap electricity rates.

Bitcoin hashrate today: 250 Ph and flat
https://blockchain.info/charts/hash-rate?showDataPoints=false&timespan=&show_header=true&daysAverageString=7&scale=0&address=

BitFury: 100 MW with .2 J/Gh = 500 Ph

If BitFury wants to roll out 500Ph and control less than 51% they need to:
 - 1) either have the network reach 1 Eh, therefore they need someone else to add another 250Ph
 - 2) either start selling and shipping their hardware / chips, in which case the 100MW argument becomes irrelevant.

Let's go with 1), 250 Ph / 1 Eh = 25% of the network

Who is going to sell / own those 250 Ph?
Seems in line with AM's plan.

You're absolutely bonkers trying to spin this as somehow being a positive for AM.  Its right up there with the dude saying having 3x worse power efficiency is a good thing because it allows you to serve different markets.

A few hints for you: BF has no incentive to maintain less than 51% of the network. Aside from selling actual hardware they also resell and host a significant portion of their hashrate to partners like cryptx and DigitalBTC. No one cares if >51% of the network runs on hardware produced by the same vendor. 

Moreover, BF doesnt have to fill its DC's to capacity. They will add hashrate for as long it makes financial sense, regardless of their % of the network. If it no longer makes financial sense for BF to add more, despite having access to hardware at cost, access to extremely cheap hosting and electricity (check out their datacenter design and electricity prices in georgia republic) and despite probably having (by far) the most power efficient hardware, then who do you think will buy or deploy AM gear?

Of course, bitfury still has to make good on its promises, it may fail to deliver, or you may hope on it being a bluff, but based on their trackrecord, I wouldnt bet a satoshi on that.

You mean Bitfurys track record of failed 40nm, 28nm, and 20nm ASICs? I would bet a few satoshis on them missing their target again.

Don't forget that when Bitfury says 0.2 w/gh they mean underclocked to the best possible efficiency. They will most likely fill the DC with ~0.5 w/gh hardware until it makes sense to underclock.

They said when? January? August? Did they say that their operations or most of them were in Canada? Just because the headquarters are there doesn´t necessarily mean that the operations are there too.

What makes you assume they are located in Iceland?

As I said, even if they have the worlds cheapest electricity and have hardware costs below every manufacturers production costs, their contracts are still too low for them to make a profit.

PBmining would have to be most efficient mining operation in existence to be legit.

There are tons of people who would be willing to invest massive amounts of cash in to such an operation but it's never going to happen when PBmining dresses themselves up like a ponzi.

Who´s the head of the co.? CEO, whatever.

Nobody knows. There is absolutely no public info and much effort has been put in to keeping it as secret as possible.

I can even understand if the CEO wants to remain anonymous, but I cannot come up with a single good reason to implement a coinmixer and hide the mining address.
869  Economy / Services / Re: PB Mining -- 5 year mining contracts! on: October 22, 2014, 04:20:40 AM
But are you sure they´re in Iceland? I mean, it´s a tiny place. Everybody knows everybody else. It´s not like you´re searching for something in bloody China. Not a very promising location for a cloud mining scam.

No they said their operation is in Canada not Iceland.

Quote
And why haven´t the competitors sent someone to check this out? Or hired someone locally.

Check out Pbmining or Iceland?

Clearly many mining companies are already moving to Iceland, that's no secret.

Nobody could check out PBmining because they will not tell anybody where they are located. Nobody knows anything about PBmining other than they are located in Canada.

As for the costs you mention, it´s possible that they´re just a department (a room of racks) in a private company which mainly mines for its owners and has this as a side business.

That doesn't explain the costs. If they are really located in Canada then electricity for only a single year would cost more than their contract price.

Even if they get hardware for $0.2/gh (which is below every known manufacturers production costs) and electricity for $0.04/kwh, there's still no way Capex plus Opex over one year is less than $0.6/gh.

Also several manufacturers have vouched for cloudmining companies before, why not for PBmining who gets more ponzi accusations than every other company?
870  Economy / Services / Re: PB Mining -- 5 year mining contracts! on: October 22, 2014, 03:34:13 AM
But what does it have to do with PB Mining? Are you saying that they´re part of this Verne Group? I never claimed that this news story had anything to do with PBM as you may or may not have noticed.

No of course they are not hosting their hardware at Verne Global. If that were the case then they would have had Verne Global vouch for their legitimacy 8 months ago when the ponzi accusations began.

As a native you should know that Iceland has some of the cheapest electricity in the world. Canada (where this farm is located) is much more expensive.

But let's say they somehow have access to Icelandic rates. Most of their hardware was purchased before any <1 w/gh hardware was shipping from stock so we can assume their hardware is all or mostly 1 w/gh.

$0.000043/wh * 24 * 365 = $0.37 * 1.1 (PUE) = $0.41/GH/year in electricity costs.

Subtracting $0.41/gh from the contract price of $0.62/GH would leave $0.21/gh to purchase hardware, buy a warehouse, fill it with racks, add cooling/power/networking infrastructure, pay staff, pay taxes, spend boatloads on advertising, etc.

Seems a bit of a stretch considering no manufacturers are selling hardware for less than $0.4/gh.
871  Economy / Services / Re: PB Mining -- 5 year mining contracts! on: October 22, 2014, 02:02:11 AM
And since you assert that mining operations pay $0.043 per kwh in Iceland

presumably you have access to contracts confirming this.

Please provide the links.
Of course I don't have them. Those rates are on 12 year contracts, it's entirely possible that they are paying more than that. Please provide links showing they get 0.043 or below. Better yet, show some proof you have done any mining at all.

Landsvirkjun is the national energy company and largest producer in Iceland though. Their rates are likely indicative of the general market, though if you have any kind of information that anyone pays significantly less than that price I'd love to see it.

Please pay attention.

Landsvirkjun doesn´t provide electricity to the location covered in that news story I posted.

You people are very quick to assume and very loose with actual facts.

Here's some facts for you Mr fact checker: http://www.verneglobal.com/partnerships

You can also confirm the rates are ~0.043/kwh here: http://www.verneglobal.com/resources/energy_calculator

It's interesting you become a huge skeptic when someone makes a completely plausible statement about electricity rates, yet when someone wants to take your money via their extremely shady business there's no questions asked.

Maybe I´ll waste some time on you later, maybe throw you a bone if I notice some signs of domestication.

"""Cost savings

Monroe is very secretive about his clients and can not be drawn into conversation about specific mining rigs, though he is able to detail the cost-savings such companies are making.

"[One client] saved over 83% on their energy cost alone. But more importantly than just the energy savings - they substantially reduced their carbon footprint which for most companies is becoming more and more important."

DigitalBTC is not the only mining company to move in to the industrial park. Last month, Switzerland-based mining firm Bitmine switched from their base in the Alps to set up shop in Iceland."""

Geothermal Gold: Why Bitcoin Mines are Moving to Iceland

http://www.landsvirkjun.com/productsservices/valueproposition
$43/MWh ($0.043/kWh)
Still not cheap enough to justify pbmining's rates. With the best announced hardware (Spondoolies SP35, 0.6J/GH) 5 years of power would be 26.28kWh and cost $1.13/GH/s at that price. That's 0.0029BTC of the 0.0016BTC they are charging per GH/s, leaving -0.0013BTC to spend on everything else.
Even with not-yet-designed 0.2J/GH hardware, you're looking at $0.377/GH/s just for power, or 0.00098BTC of the 0.0016BTC/GH/s they charge, leaving 0.0006BTC/GH/s to acquire HW, maintain/upgrade it for 5 years, and make a little money.

It's still half the cost of electricity anywhere in Canada.

Maybe that's where PBmining will set up their operation if they ever decide to actually start mining?
873  Bitcoin / Hardware / Re: HashFast announces specs for new ASIC: 400GH/s on: October 21, 2014, 07:54:29 AM
I care about the fact that HF has the fastest chip because how much that IP fetches at auction directly affects how much we customers will be compensated for their delays.

Please just stop with the fastest chip nonsense. It's not the fastest chip nor is it the most gh/s to be put on a substrate.

What matters is the $/gh. Yes hashfast has a very good $/gh but you cannot say it's the best because you don't know what everyone else pays.

From what I've extrapolated AM/Bitmain/KNC/Innosilicon/Spondooliestech all pay ~$0.1-0.2/gh at the wafer like Hashfast.

Quote
Yes the golden nonce is very good in terms of $/gh (~$0.1/gh I'd guess) but the w/gh is horrible

Thank you for being reasonable.  Did you know the GN1 is very fuel efficient if you underclock it?  You can get it down to about 0.5GH/w at around half speed.

Source?

Hashfast's own misleading chart says otherwise:



That says the GN would need to be underclocked to 220gh/s for ~0.55w/gh at the chip which equates to ~0.7 w/gh at the wall and ~$0.6/gh at the wafer.

Overall the it would be mildly impressive for a $1m standard cell design but it's garbage for a $15m full custom.
874  Bitcoin / Hardware / Re: HashFast announces specs for new ASIC: 400GH/s on: October 21, 2014, 07:23:10 AM
How does an entity that designed and built the best mousetrap known to man go bankrupt, while inferior mousetrap manufacturers continue to exist, supplying their customers with highly sough-after sub-par products?

You act as if HF is the first company in history to go bankrupt despite having a superior product, but you are far too old for that to be the case.   Smiley

Yes, HF is the first bitcoin manufacturer in history to spend ~$15m on NRE and design a chip that is only on par with the competition.

BTW where is the document that outlines Hashfasts expenses? I've been looking through the documents here but can't seem to find it: https://cases.processgeneral.com/cases/document/case/5/hashfast-technologies-llc/

Both definitions are correct, but in common usage the complete die(s)+substrate package constitutes a chip.

No both definitions are not correct. A substrate is just the board part of any PCB (other part is components/copper traces). There are no ASICs that do not go on a substrate.

Quote
If I'm wrong, please tell the class what competing die(s)+substrate object offers higher performance than HF's.  Come on, don't be shy.  You can do it!  Oh wait, no you can't.   Roll Eyes

I'm assuming you mean in terms of gh/s per substrate so here's your useless comparison:

Hashfail - 750 gh/s
Cointerra - 800 gh/s
SP10- 800 gh/s
SP30- 2,250 gh/s
BFL monarch - 800 gh/s

Quote
Since you want to be a pedant, let's just agree that HF's GH per sq mm of wafer is the highest of any design, regardless of how obnoxiously narrowly you want to define "chip."   Grin

If anyone is being obnoxious it's you. Nobody cares about how much gh/s you can fit on a chip/pcb. What's important is the $/gh and w/gh for complete hardware not just the chips.

Yes the golden nonce is very good in terms of $/gh (~$0.1/gh I'd guess) but the w/gh is horrible and the amount of money they spent on engineering completely negates the production cost savings.

Why do you keep defending HF like you are Hashfast_CL's retarded little sister? "We got the fastest chip". Who cares. Bottom line  matters: HF did not deliver a working solution to their customers on time. And it turns out that most of it is to blame to incompetence too.

I think I remember a rumor that Icebreaker actually was Hashfast_CL. It really does make sense now. Nobody other than Icebreaker could completely destroy hashfast reputation and anger customers like Hashfast_CL did.

Are you too cranky to acknowledge the simple fact that HF's 750GH/s/chip (whether full or partial custom) is still the world record holder by a large margin?

PS  Inaba, it's one chip with four dies.  Chip = [die(s) + substrate package].

Wrong once again.

Its to represent that what they pulled with the 65nm delays, mis-selling, making potentially false/misleading claims, potentially misleading statements about tapeout etc, targeting new buyers with insanely old hardware and the repeated 'tradeups' with the second generation delays. Simply put, no other company has come close to what BFL did over the last 18-24 months - as highlighted by the FTC taking over the company. Blackarrow is getting close, but they're not at that level yet and still have an opportunity to fix it.

Blackarrow

- Repeatedly lied about shipping dates.
- Only 30% of hardware shipped 6 months late.
- Promised to be the best $/gh but decided screw it that would cost money.
- Several customers blackmailed/doxed by the company
- Shipping hardware to resellers before customers who ordered earlier
- Denied refunds even though they were promised after they began shipping.
- Compensation completely garbage for the huge delays.
- Heavy censorship of their thread/forum.
- Nearly every customer left feeling ripped off.

Ethics: 5/10

BTCGarden

- No delays
- No problem with RMAs/partial refunds.
- Great customer support which makes sure customers do not feel ripped off.
- MAY have told a lie about their DOA %.

Now let's keep this thread on topic and tell me what's the difference between AM's pre-orders and SP-Tech's ones and if they should be on par or not in dogie's guide.

It's been spelled out for you several times already, I'm not sure anyone can simplify it further.

Please just try to learn the difference between built-to-order and preorders.

The SP10 was BTO because they built/tested a prototype and verified the specs before taking orders.

The AM Prisma is also BTO because they built/tested a prototype before taking orders.

SP35/31/20 are all preorders because they use an untested chip and the specs are estimations.
879  Bitcoin / Hardware / Re: [Guide] Dogie's Comprehensive Manufacturer Trustworthiness Guide [12th Sept] on: October 21, 2014, 01:30:21 AM
I agree with dogie on this.. AM was not really a pre order since they had chips in hand. AM just needed new boards and they had a holiday. SP is defently a pre order company...


Now scamalon being rated higher than AM is just silly though.

Please re-read my post. SP-Tech has chips in hand since August. What's the difference between AM and SP-Tech if they both have chips in hand and the product are already developed?

So what you are saying is that Guy lied when he said:

The SP20 should give better results then what we published. We'll get the faster ASICs in 2 weeks and revise the spec.

It's only 3 weeks past the date they expected to publish the "fast ASIC" results but I'm sure the delay/silence can only be a good sign.
880  Bitcoin / Hardware / Re: [Guide] Dogie's Comprehensive Manufacturer Trustworthiness Guide [12th Sept] on: October 21, 2014, 01:15:30 AM
Could you explain what BFL'ing is as far as ethics?  I cannot find anything where BFL has been worse than BA and yet they still have an ethics rating.  Just some clarification here would be helpful.

I agree blackarrow is about as bad as it gets when it comes to ethics.

They have also announced that they are broke (aka bankrupt) and have had a large amount of coins stolen (apparently their security isn't great as they also apparently had their email list stolen). So that should also fit in somewhere.
