and it will store all output in log.txt... though all of that and much more is documented in the readme as well.

Crap, good pickup. I must have enabled it by mistake during debugging and it ended up in one of my commits.

The message you keep quoting was removed which is why I said it raises a number of possibilities. While I appreciate your suspicions bringing to light these allegations, you are unable to conclusively say anything. I've made no assumptions, I just want a clear statement from bitmine regarding this manufacturer. The claims regarding stealing or counterfeiting are as you are no doubt aware very serious allegations and if they do not come forth with these allegations and stick to only non-specific cautions on their site, then I have to give JTminer the benefit of the doubt. So depending on how (and if) they respond, I will be getting the hardware working with an alternative power source and continue down the software path which is all I was originally interested in - or - I will hand the hardware over the AFP.

35c/kWh, mine are long gone...

Put the discussion on hold for the time being. I'm asking bitmine directly for I certainly do not want to be put in the middle of such controversy. I can easily see a number of possibilities for how it has ended in this stalemate, and it is not clear to me that there is incontrovertible evidence saying that JT produced these illegally, nor that any stealing was involved. A statement from bitmine is the only thing that can clear this up one way or another. If bitmine do not respond then I have to assume Innosilicon do indeed have the right to produce exact copies and sell these chips.

Aye, they even have Innosilicon as a hyperlink.

Indeed not as you can see on the pictures. It's simple enough to use a different power source though. You have done well to point out enough controversy surrounding these devices, but the claim on the bitmine website is they could be a scam (they've sent me hardware, I'm not saying whether others will get hardware), or they're sending some kind of inferior or imitation product - and I can't attest to any of that.

But stolen goods? IP concerns?


I don't see evidence to make that final association, but I shall ask bitmine myself.

Is this the post you're saying was removed?


Feh this is ugly and I'd seen none of it cos there's too much forum activity to keep track of.

The website caution is:

Where does it say anything about stolen goods?

Sure it's easy to wire up. But it's also illegal to do mains wiring yourself here. PSUs would have been much simpler, but in fact these are much higher quality and more expensive than regular PSUs.

It's as per the opening post, but with one extra power supply (presumably a spare/redundancy). Here's some photos, including a baseball cap for size comparison:

Yes that's almost certainly the queue increasing in size automatically, which I will likely remove next version.

I was not aware there was anything claiming these were stolen apart from some questionable post on an unrelated forum with machine translation? If you can point me to reasonable suspicion these are stolen goods I'd of course have no interest in reviewing or promoting them - heck it would make handling them and not trying to wire them up much easier, just give them to the AFP. I'm very open about all my actions and put my real name to my actions here at all times and have never tried to hide my identity so of course I wouldn't go incriminating myself knowingly.

Got it. It's a monstrosity with 3 external power supplies that I have to wire in myself... however even the power side needs to be screwed in with bare wires, and that's basically illegal to do in my country unless you're a certified A grade electrician... so I'm not sure exactly what to do with it yet 

They asked me to review it I said I would not, as I am not in the business of reviewing hardware or supporting any manufacturer. They then offered to send me hardware, to which I said I would graciously accept it - to make it possible for them to submit their driver code for inclusion to master cgminer and have me help them. When the hardware arrives I will gladly validate that it exists, hashes etc, but I cannot vouch for the company's business in any other way since I am not a customer as such.

There's already a (recent) thread asking for the same:

https://bitcointalk.org/index.php?topic=438043.0

And there have been plenty of others in one form or another.

This was my (mining focussed) take on it:

CPU and GPU mining days for bitcoin mining are long gone. With a CPU you use 1000 times more in electricity than you earn in bitcoin, with a GPU 100 times more than you earn. Each difficulty 1 share takes over 4 billion hashes to find on average, and your CPU is doing 1.4 million hashes per second. That GPU will do something like 700 million hashes per second which is still ridiculously low for the amount of electricity it uses. It is only worthwhile bitcoin mining with hardware that is designed purely with bitcoin mining in mind (i.e. ASICs) today. The days of off-the-shelf commodity hardware being able to meaningfully bitcoin mine ended a year ago.

You are probably getting confused by threads discussing altcoin mining with GPUs. That has nothing to do with bitcoin mining.

That is not charm, everything uses the WinUSB driver on windows on cgminer - you install one driver for everything and just associate it with your device if you ever get a different type of device. Saying a driver happens to work for a piece of software is not really something special...

And coincidentally, I happen to have all the devices you're describing.

And they all work fine on my rig.

Once the drivers are set up on cgminer, you can plug and unplug as many of those same devices as you like and cgminer will hotplug and unplug them without any further intervention.

I have a tracking number, so *something* is being sent to me, for what it's worth.

Guys, if you get a crash, debugging information will help everyone long term since that's how I'll actually get to fix the bugs. This is not a closed source proprietary piece of hidden software, it is a community project  despite the fact there are only a very small number of developers, and we need information from the users as much as they need our code. While I'm forever developing code for new features and drivers, I am seriously interested in stability over anything else. My rigs run for months without a crash and that's how I want it to be for the other users, but I don't have all hardware combinations on all operating systems (nor do I even want that). I've debugged a LOT of issues courtesy of debug traces, logins into other people's machines and bug reports and so on that would never have been fixed otherwise.

Unless the crashing is because the software is fighting over the device in which case it will go away.

Well I already gave you a link to the instructions on how to help... but by far the easiest thing for you to do is just mine with everything on cgminer as the NF1 devices as they're called by cgminer are fully supported, and you set them up exactly as you set up every other USB device you've used so far on cgminer so it's about 10 seconds' work.
