Bitcoin / Mining speculation / Re: Ultra-Low-Voltage Energy-Efficient Bitcoin Mining ASIC from Intel (23 Feb 2022)

on: February 20, 2022, 01:16:34 AM

Folks here should realize that Intel is talking about Blockchain Technology in it's myriad of current and possible applications - NOT just Bitcoin. From the news release: Quote We expect that our circuit innovations will deliver a blockchain accelerator that has over 1000x better performance per watt than mainstream GPUs for SHA-256 based mining. GPU arrays are of course not used to mine BTC but they are used in blockchain-based logistics tracking applications, large scale Public Utility assets tracking, etc. that use blockchain tech for the records keeping.

I don't recommend this for safety purposes I suggest you better use only official and trusted monitoring tools. Good afternoon. I am the developer of this program. My name is Andrey Bobrov. If you have any questions, ask))) All information about the program in the telegram channel @AvalonMinerViewer welcome With all respect, Andrey BitMaxz hit the nail on the head. The program is only available in compiled versions and without other people being able to examine and vouch for your code you will have a VERY hard time convincing people here that is safe to use. This Forum is not like your usual other Social Media sites which are mostly populated by people that are absolutely clueless regarding cyber security. On those other sites even a crappy hacker can be like a wolf among the sheep -- they just have to be a good 'talker' and enough idiots to make it worth their time will gleefully install anything on their smartphone/tablet/computer. Make it open source so reputable eyes can examine it along with you providing instructions for people to compile it for their choice of operating system and this would be a whole different discussion. Barring releasing the source code, do you at least have a track record of other programs that folks have used and reviewed? Anyone successfully involved in crypto knows that is a digital FINANCIAL TOOL and that they should be very protective of their assets. As such most are very rightfully wary of any software placed on their digital devices or ANY device they connect to.

Only thing certain such a scenario is that Diff would drop like a stone and the few miners left will be popping blocks left and right... In the case of BTC still only 1 every 10 min on average but with far fewer folks being able to mine the odds of any 1 person getting it will go up dramatically.

Quote from: stompix on February 18, 2022, 12:38:07 AM ... But, the image of the miraculous miner is gone, probably they are photoshopping something else, also you can't really directly order from the website, you have to send an inquiry, probably selective scamming as not to piss the wrong guys? heh, on Feb 10 they even went as far as to publicly announce the image was faked. Quote NuMiner’s original image was drawn for marketing purposes. The Company was recently made aware of a similarity in the product’s image to another product on the market and removed the image from its website. ROFL -- Just A similarity? This 'multi-million dollar' company couldn't even hire a technical illustrator to draw their vision of what their unicorn miner may look like but instead had one of their kids photoshop a real piece of hardware (the Cerebras) that has nothing to do with mining? Gotta love this from their FAQ: Quote How is the NM440 better than other bitcoin mining technology on market? The NM440 combines innovative processing technology and design to introduce the world’s most efficient and powerful miner. The NM440’s leading performance and distinctive advantage is powered by groundbreaking proprietary hardware and software. In not so many words: It's majik and therefore a secret...

You are attempting a very useless project. Try reading the pinned message at the top of this area: Quote 3. Mining BITCOIN is done exclusively with dedicated BITCOIN mining hardware based on ASICs - https://en.wikipedia.org/wiki/Application-specific_integrated_circuit . You CAN NOT meaningfully mine bitcoin today with CPU, GPU or even FPGAs. Bitcoin difficulty adapts to match the amount of mining done on the network and has reached levels trillions of times too high to mine meaningfully with PCs, laptops, tablets, phones, webpages, javascript, GPUs, and even generalised SHA hardware. You will not find software in this section to help you mine bitcoin in this absurdly inefficient manner in this subforum. It would cost you thousands of dollars in electricity per year to earn only a few cents in bitcoin. Even if you combined all the computers in the world, including all known supercomputer, you would not even approach 0.1% of the bitcoin hashrate today. Any discussion outside of ASIC related mining, except in the interests of academia, will be moved to the altcoin mining section.

Bitcoin / Mining / Re: any alternative android or windows apps like pi network

on: February 15, 2022, 11:24:34 PM

In addition to what's already been said above ^^ there is the huge matter of security. If you insist on finding and using such apps then ONLY use ones found on either Apples official store or the GooglePlay store. At least those should have been verified as 'safe to use' by Apple and Google. Even that is no guarantee of nothing nefarious (malware) being in the download but it certainly helps. When installing the app damn well better trigger your phone/tablet/whatever OS to ask for Permissions: things like access to your contacts lists, DENY!, your camera, DENY!, your microphone, DENY!. etc. There is no reason for a 'mining' app to need access to anything not relate to mining. If the app does not run without said access -- delete it immediately. Any app's downloaded from any other site than the official Apple and Google stores is playing Russian Roulette with the security of your data on the device and possibly any other device yours connects to.

Bitcoin / Legal / Re: Coinbase and TurboTax Offer Tax Refunds in Bitcoin

on: February 15, 2022, 02:21:31 AM

The only downside to it that I see is that you have no control over what the fiat refund to BTC exchange rate is. You might get lucky with BTC dipping to a low price when the refund system tells Coinbase to buy (good to great) or it may happen at a peak which is not so good... Anywhere in between - meh. Personally, I'll take the refund as fiat and buy when I like the price.

Bitcoin / Mining support / Re: Where to fix your Asic miners.

on: February 13, 2022, 02:45:28 AM

Quote from: mikeywith on February 12, 2022, 09:47:29 PM Quote from: NotFuzzyWarm on February 11, 2022, 11:35:33 PM as of late the PSU's seem to be the weak point. Also one that should be very servicable. You are right, someone recently reported a 25% failure rate on s19s PSUs, they seem to have fixed the heatsink/chip solder issues they had with the 17 series and now started to screw with the PSUs. That is astonishingly bad... Switching power supplies are not rocket science and by nature of their simplicity, should be damn near failure proof. Having a 25% failure rate points to some serious design compromise issues in trying to get the lowest possible build cost. Hell, even a 1% failure rate should be cause for concern. My 1st guess from a manufacturing cost standpoint would be the output filter caps. Switching supplies operate at a very high frequency - well over 100kHz - and that demands very careful selection of the caps. They MUST be a type with very low ESR (Equivalent Series Resistance) using either a X5R or preferably, a X7R material for the dielectric. Thing is - those cost over 2x what a common general-purpose ceramic cap costs and are produced in much lower volumes than the more common and more easily available ones. With the switching frequencies the PSU's operate at using electrolytic caps is out of the question when designing for any sort of reliability plus would be too bulky compared to ceramic caps. While you can use the lower cost common ceramic ones they WILL fail from internally overheating and current erosion even when using a lot more individual caps to spread out the loads reducing current spikes and resulting heating in the individual caps. At that point it becomes a balance between reliability (use the correct low ESR caps or more of the common caps along with just how many more of them) and cost. Think we know who had the final say: Accountants, not the Engineers... The line side of the supply is harder to screw up by using under-spec'd (cheaper) components and same for the switching FET's, we're talking only a penny or two difference in cost between parts rated for x voltage/current and ones rated a bit higher. Again, it would be great for someone to do forensics on a few dead PSU's to find out what their failure mechanisms are.

I have very limited knowledge in this field, but I am certain your guys don't need "formal training" if they are good at what they do already, wndsnb is now professional in hash board repair, I don't recall he took any courses, but he indeed is very talented in his field and was able to quickly able to learn how to deal with all that mess. I got nothing against "special training" to speed things up, but I don't think that kind of training is available anywhere outside of China and maybe Russia, to send 2-3 guys it will cost a few tens of thousands of dollars, since you have the tools (judging by your current business) you can just buy a 1-2 working miners, and a few dead hash boards and get your guys to self-learn, the resources online are somehow limited, but they are there nonetheless. Well, the OP could always reach out to Canaan... They did a very nice round of training for Hagss - and paid for it all including travel Mikey would have to chip in on this but as I've said, looking through miner fault posts, as of late the PSU's seem to be the weak point. Also one that should be very servicable... Perhaps someone could send the OP a couple dead PSU's to have their folks take a look at them

on: February 10, 2022, 05:06:22 PM

Quote from: SWTEL on February 10, 2022, 02:49:20 PM I am new and trying to educate myself. I have owned a telecom equipment resell and test/repair business for over 20 years and have recently noticed that the ASIC machines are not unlike some of the boards, power supplies, fans etc. that are used in telecom industry. I am considering sending a couple of my technicians for formal training in ASIC repair to add to our list of services. What I have learned as a female business owner is to research fully, listen to your customer base and surround yourself with those smarter than yourself, which led me to this forum. So my question is, what is the demand for reliable repair facilities in the US? Just do a few minutes browsing this support area and the hardware area and you will see that demand is very high mainly due to a certain miner manufacturer (Bitmain) having released several models that had horrid build quality. These days a common fault with miners from any manufacturer is the PSU dying. Thankfully those are easier to diagnose and repair than hash boards are but there are very few companies in the world, much less the US, that will repair them. I would think that the main faults that happen are either the line-side input stages or the switching FET's blowing. The main 'gotcha' to servicing them is that they are programmable PSU's (I think using I2C, or possibly an analog control) so you have to be able to rig a micro controller to talk to them.

Quote from: HagssFIN on February 09, 2022, 07:35:01 PM Oh fuck, you used Nicehash as a pool. Well that explains the problems you had. Ja. NH requires miners to support using #xnsub and that is a security hazard. Not only does #xnsub allow NH to seamlessly change the miner work but it also allows ANY other subroutines to run in the background without you knowing about them. For the above reasons Canaan miners DO NOT support using it.
