GPU or Asic mining

Ok, A little backround. I know hardware and networking. I can build just about any config of a computer. I understand overclocking and undervolting. I can invest around 2,700 for initial investment.
So do I buy hardware to build a GPU miner with at least 6 cards or more? Probably RX580 as they are cheap and I have one in my rig. More on that later.
Or do I a Asic miner like this I understand a GPU miner is multiple coins and not Bitcoin, and Asic is nothing but Bitcoin.
I've done the math on the Asic miner and the ROI in about 3 months with a net gain of about ~10,000 USD a year @ .13 cents per Watt.
I've had a hard time finding a solid or semi way of calculating the earnings for a GPU miner. Not only because it is many coins or dedicated to one coin, but there our other variables involved. However I have more control of the hardware if it fails.
I dipped my toe into mining with my own rig that has a RX580 fatboy and a AMD Phenom ii x4 955 black edition. I overclocked the GPU and undervolted the CPU to reduce heat since it was hitting 62 cel.
The GPU gets 12.5 sol/s and the CPU was getting ~322 h/s. All this added up to ~170 watts and a net of .00218322 BTC/Month. This was all done using Cudo as it was easy to find and setup just to test. This was just a test to see how it would work. I wouldn't use Cudo to full scale as it is a pool and the transfer to a Wallet is pretty steep in relationship to earns. I understand that in a pool you get your share based upon how much of the "work" you did to get find block.
So do I build or buy? With that much computation power do I need to join a pool? What software is best for pool or alone? I am comfortable with CLI as long as it's well documented, but would like a remote GUI.
Also what is the best wallet with the best fees for transactions. Currently using uphold since I use Brave.
I think I covered as much as I could, if you have any questions let me know. Any advice would be great. If I should post this else where let me know please or I could just cross post it.
TIA. Be safe, stay safe!
Edit: Words and BTC earning was WAY off then I first typed this.

[PROJECT] Bitcoin Mining Profitability Calculator

DESCRIPTION
This project will help you to calculate the earnings of your mining hardware, providing you the total earnings (approximate) based on: power consumption (*), electricity cost (**), per-device income and the time it will be mining.
This project includes an Initial Setup task that needs to be executed when it is imported from TaskerNet, or when the dev considers it is needed even not imported from TaskerNet.
Notes:
- Thanks to flaticon for the pics.
- This project won't provide you the current hashrates and/or possible earnings for your devices based on an on-line database. It just makes calculations based on pre-defined entered user data. But at least, you won't need internet access to make a quick calculation for approximate values. So, to get current and software based values for your devices, check appropriate web platforms.
- The project was based on bitcoin cryptocurreny type, that's why 'Bitcoin' appears on its name. But it can be used with absolutely any other type of currency, if needed.
- (*) To get the power consumption (watts) of your device/mining rig, you can check on-line references, specialized web services (OuterVision PSC, as an example), forums, or use a digital power meter (HiDANCE, as an example).
- (**) To get the electricity cost check your own bills, since they usually have it well detailed on the reverse. You can also get the taxes, if applicable.

[Researh] In 2017 bitcoin network consumed 5 TWh of energy, in 2018 – 29 TWh, in 2019 – 43 TWh. Banking industry consumes 74 TWh per year.

[Researh] In 2017 bitcoin network consumed 5 TWh of energy, in 2018 – 29 TWh, in 2019 – 43 TWh. Banking industry consumes 74 TWh per year.
Electricity consumed by bitcoin network has been constantly and noticeably increasing. During the past years the consumption reached such big a scale, that it can be compared to electricity consumption of some countries, according to BlockchainAnalytics.pro research.
The world’s first cryptocurrency is steadily becoming more popular and expensive every year. This motivates more individuals and companies to enter the mining business to earn a bitcoin share.

More miners, more efficient equipment

To validate a block of transactions and receive a reward, miners compete with each other by solving a deliberately complicated mathematical task, or puzzle. Those miners who own more computing power (hashrate) have more chances to win the competition. This incentivizes miners to buy more powerful equipment that consumes more electricity.
At the same time, mining equipment efficiency is constantly improving, and with time less electricity is required to produce the same hashrate. This factor allows to slow down the increasing demand for electricity.
For example, in 2016 Bitmain, world’s largest manufacturer of mining equipment, launched the legendary Antminer S9, which consumed 100 watts to produce one terahash per second, or 100 W/TH/s. The best modification of Antminer S15, released in 2018, consumed 57 W/TH/s. Currently, the most efficient Antminer S17 consumes only 40 W/TH/s.
https://preview.redd.it/gh343l3p09j41.png?width=930&format=png&auto=webp&s=e350c1e7832e37c1e3c3aeac974428cca7f0f874
It is assumed that the market competition compels manufacturers to keep up with each other in developing more efficient hardware. If some manufacturer brings next-generation chips to market, other manufacturers start to produce chips with the same characteristics at about the same time.
On the other hand, new miners are joining the network, thus increasing the hashrate. So the demand for electricity continues to grow. Also, it can be noticed later that the electricity consumption chart is similar to that of hashrate chart.
https://preview.redd.it/3k32ci6q09j41.png?width=930&format=png&auto=webp&s=e70f600419bcbc9e7e82506b5f12bf4da6f00584

Calculations

The incremental volume of electricity consumption is calculated by multiplying newly added hashrate by the best mining efficiency available at that moment.
The sum of incremental volumes represents cumulative amount of electricity consumed by bitcoin network. The metric is expressed in terawatt-hours (TWh). To get annualized volume in terawatt-hours we multiply the consumption by 24 hours and 365 days.
A 100-day moving average was applied to hashrate to make the final result less dependent on the short-term hashrate fluctuations.
Assumptions, used in this study, are very conservative. It means that the results are in the lower limit of the range of possible volumes, and the actual electricity consumption can be higher.
A detailed explanation and interactive charts are provided here: https://www.blockchainanalytics.pro/btc/electricity-consumption/
https://preview.redd.it/jol3703r09j41.png?width=929&format=png&auto=webp&s=252d4d67ff6882bb32ad63238537a41305719f05

Results

Currently, annualized electricity consumption in bitcoin network is 57 TWh. To help readers get an idea of how much electricity the bitcoin network consumes, a comparison with some countries is provided alongside.
Portugal consumes 49 TWh per year, Romania – 50 TWh, Czech Republic – 59 TWh.
Some more numbers for comparison:
https://preview.redd.it/hka7lcwr09j41.png?width=930&format=png&auto=webp&s=92d6d0b25f922a1e6f0c45c6f994e78aded6f920
According to conservative estimates, the bitcoin network will consume more than 70 TWh in 2020. This is on a par with Chile, a country with 18 million population.

More thoughts (estimations of how much energy banking industry consumes)

Some information from official reports:
Taking into account the information above, we can assume that, on average, banks spend ~20 kWh per customer per year.
Some information on world population:
  • 69% of adults around the world have a banking account (source)
  • 70% of the world population are adults (source)
  • World population is 7.7 billion (source)
Finally: 7.7 billion people * 70% * 69% * 20 kWh per year = ~74 TWh per year
So, we can assume, that banking industry consumes ~74 TWh per year

Mining profitability gaining momentum

Mining profitability gaining momentum
We are back!
For the last 2 years there was not much to shill in mining mining was on the life support. And the profits constantly got decreasing. Start of 2020 Bitcoin and Altcoins are showing great performance in price action. This price action has also increased mining profits in some coins for more then 100% since december 2019. It might be to early to say that “we are back” , as crypto can be so unpredictable. But there is a lot of signs that we have now oversold a lot and value of crypto market is increasing steadily. We might see this pattern continue for good bit of times as BTC halving is coming up in 3 month. Let’s get in straight in. I will choose 3 hardware devices which in my opinion would be the best choice and we will see how profitable they are.
If you are new to mining and you want to know which devices to choose, choose from top market cap coins latest equipment. This will be your safest bet, as the mining profits are much more stable on bigger cap coins then on smaller cap coins. If you are small miner and don’t have large electric bills, you can choose smaller cap coins. They might go up in price lot faster then bigger cap coins in bull market, but be aware they they might dump lot faster. It is high risk high reward type of mining.
If you are really serious about mining, you need to look at cheapest power source possible which would be in 0.05c a kw/h range. It is not 2017 and mining from home wont be profitable at 0.30c a kw/h. Industrial power is possible to achieve 0.05 in many places in the world. If it is not possible in your country , look for the country where it is possible. So all profit calculations done for 0.05c a kw/h
Top mining profitability websites :
  • https://www.asicminervalue.com/ It is great website to see newest ASIC miners and their profitability. Usually the new upcoming mining machines gets listed here. So come and checkout this page every few days/weeks this page if you are serious about mining.

https://preview.redd.it/aut9qgz76df41.png?width=1206&format=png&auto=webp&s=b85486b8b0171c91301c6fa9827bc3795a4ea2b7
  • https://whattomine.com/ Is the best known for GPU/CPU mining profitability. You can choose what ever hardware to use and it will give you the best and most profitable coins to mine. It is very simple to use it. It does have Also asic miner profitability check, but for asics i do prefer asicminervalue,com

https://preview.redd.it/y0xr3dr86df41.png?width=1182&format=png&auto=webp&s=439e7cb67f8becc86f4d97c128504636922939e9
The top and 3 most profitable Crypto currencies to mine in February 2020 , for some people miner pick could be different. The prices changes if you are buying new/used , depending in which part of the world are you. This is my recommended , brand new purchase in Europe.
  • Bitcoin – Most suitable Antminer S17+ . It is one of the efficient Bitcoin miner currently publicly available, alternatives would be M20s miner and Avalon miner 1166. Antminer S17 efficiency is 73TH/s @ 3000watts . Current profitability after you have paid your electric bill is 7.82 usd in 24hours , with ROI achievable in 6-7month. It does seems great, but crypto doesn’t stand still. And has plenty of risks.

https://preview.redd.it/msokirj96df41.png?width=891&format=png&auto=webp&s=7552b4aff2c0df4c25d9a72ecc25dfb4c2510f43
  • Ethereum – Best miner to use is RX5700 graphic cards mining rig. I know there is an ASIC miner available A10, but most of you who are in mining will agree with me, that it is complete junk. It is only slightly more efficient then RX5700 gpu rig in terms of price per hash and watt per hash . But it is 10x more riskier investment in mining rig then buying GPU mining rig. So the efficiency of 12xgpu RX5700 mining rig is 640 mh/s @ 1700watts. Current profitability after you have paid your electric bill is 7.62 usd in 24hours , with ROI achievable in about 20-22 month. Ethereum is one of the underdogs which could perform quite well in 2020 and might reduce your ROI much more faster.

https://preview.redd.it/ajx9eyfc6df41.png?width=894&format=png&auto=webp&s=30442d846a9d70ea3eaac6eaf7c2bdbe476384e4
  • DASH – Lately has been released most efficient DASH miner STU-U6. Asic miners are very risky investment, but sometimes they might be very profitable. The beauty of this miner is that it is quite new model and it is mining profitably DASH , even that DASH is still over 90%down from its all time highs. This miner performance is 420GH/s u/2100 watts. Current profitability after you have paid your electric bill is 8.11 usd in 24hours , with ROI achievable in about 5-6 month.

https://preview.redd.it/l80xnwbd6df41.png?width=902&format=png&auto=webp&s=5620ecf7af742cdcae0ae7010cf910d9131ae801
These would be my to pick miners for start of 2020. There is big risks in any on these miners as no high reward investment is guaranteed anywhere. I’ll have more detailed explanation of the risks of each of these miners in my next post.
Any miner suggestion, what would be your best choice and why?

The case for a legal prohibition on proof of work

I think that based on policy precedents in Western societies, it's bizarre that Proof of Work as a system hasn't been faced with any legal prohibition yet. The main argument I can imagine is that governments fear a public opinion backlash. However, a ban on proof of work would fit completely within a trend of governments banning the use of technologies that are excessively wasteful when perfectly valid alternatives are available.
Consider some examples of legal requirements the European Union has placed on products to reduce our waste of electricity:
-The EU banned incandescent light bulbs, to reduce electricity use. These light bulbs convert less than 5% of electricity consumed into light, so the EU mandated that people would resort to more efficient light bulbs. The new light bulbs have various downsides, but the need to reduce electricity use was considered significant enough to mandate the phase-out of incandescent light bulbs.
-The EU has implemented a ban on vacuum cleaners that consume more than 900 watts. Vacuum cleaners have to abide by strict regulation in regards to how much noise they produce, how much dust they pick up and how much electricity they use. The EU expects their rules will reduce electricity use by 20Twh per year, equivalent to the annual energy use of Belgium.
So, I'd say there's a good policy precedent that processes that consume excessive amounts of resources end up facing legal prohibitions in the European Union. But then I'm confronted with a bizarre situation, where an online digital currency that consumes three times as much electricity as these inefficient vacuum cleaners waste, is simply ignored.
From the perspective of energy-efficiency, Bitcoin doesn't do anything better than the regular financial system. It consumes more electricity, to make three orders of magnitude fewer transactions than credit cards do. The problem with proof of work is intrinsic: It generates an artificial financial incentive for the waste of electricity. It creates a bounty, equivalent to the inflation rate of the currency, that serves to generate a competition over who can prove the waste of more electricity than others.
Most important however, is the fact that it incentivizes the use of stolen electricity in a manner that was previously unheard of. After all, if you're mining Monero with your own equipment, you're doing it wrong. The clever Monero miner doesn't mine using his own device, he hacks into other people's computers and installs programs that make those computers devote as much electricity as possible to performing arbitrary calculations that serve merely to demonstrate someone has a lot of resources at his disposal. In other words, there's no real limit to how much electricity people are willing to waste on mining Monero, the only thing that stops these criminals is the fact that alternative scams are more lucrative to them.
In the absence of cryptocurrencies, someone who has gained unauthorized access to other people's computers has no incentive to make those computers waste electricity, except for sheer malice. The creation of an anonymous cryptocurrency that awards new units based on anonymous evidence of the ability to waste electricity, should be recognized for what it is: A bounty on pollution. Monero and assorted cryptocurrencies, exist as bounties that serve to incentivize pollution.
The nations of the world agreed to take effort to keep global warming beneath 1.5 degree Celsius. Eighteen EU countries want to move to net zero emissions by 2050. The goals nations have set for themselves will require a very rapid energy transition, yet there's serious reason to expect that these goals will require enormous herculean efforts to achieve.
So why then, I ask as a European citizen, is a free lunch being ignored? European consumers, through their purchase of proof of work cryptocurrencies, incentivize the existence of a negative-sum game of endless competitive energy consumption. I'm not allowed to purchase incandescent light bulbs because they waste electricity, so why am I allowed to buy tokens of a decentralized bounty on electricity-theft?
"We can't just knock people's doors down and check whether anyone has a Monero wallet on his computer, that's tyrannical" The critic says. And I agree, but that's a straw man argument. You don't have to treat possession of cryptocurrency the way you treat possession of child pornography.
You can instead treat it the way we treat chlorofluorocarbons, ivory, incandescent light bulbs and inefficient vacuum cleaners. European companies are not allowed to mine cryptocurrencies, the import of cryptocurrency mining devices and "hardware wallets" can be subject to legal prohibitions and companies that offer the opportunity to buy or sell cryptocurrencies can be forbidden. This would be sufficient to remove most of the incentive to participate in the cryptocurrency economy and lead to a subsequent price crash of most cryptocurrencies, which then results in a dramatic reduction in electricity use.
Please note that there are perfectly valid arguments to make that cryptocurrencies as an asset class should be banned (hint: endless fraud). I'm focussing here on the most perplexing aspect of this situation, the fact that governments faced with extremely difficult to achieve climate targets and even growing risks of electricity shortages are missing a free lunch.

The 8 Skills to Be a Good Miner

Many people may feel quite confused about their low profit now. Maybe you forget to think about the small details when you are mining. Small little details will make big difference in your final income.
Now, i want to share you the 8 skills to improve your benefits.
1, Get a cheaper power
Everyone knows the power is the most charge in mining, if we can find a cheaper electricity, it will be good. So, how to get a cheaper electricity?
55% of the mining is in China, and 40% of the mining is in Sichuan China. Why? Because there are many hydroelectric power station in there. So, you can find a place near the station and get a cheaper electricity from them.
If you can find free electricity, it is the best anyway
2, Choose low w/t machine
As you know, low comsuption machine is very popular those days, like S17 pro 53t, T17 42t. They are 7nm technical, the w/t is low and it can even overclock, it maybe a good choice. Also, we need to consider the price of machine.
Cheap price machine means fast ROI, But low W/T machine has a bright future.
3, Buy miner when BTC begin to raise after long drop
When BTC price keep falling, of course the machine will be cheaper and cheaper. When the BTC price begin to raise, we can buy miner at that time, because the price is the cheapset and you can earn money back soon.
Normally at that time, the good machine will be sold out quickly, when the market feedback that those machine are good, you may be late to get the chance. So, make your plan for purchasing before, when price down, get them.
4, Do not forget BCH, BSV, ZEN coin
Do remember SHA-256 Algorithm can mining BCH and BSV as well. Sometimes those coin may get even a better profits than BTC.
Some miner has auto setting for BTC, but you can choose BSV and BCH mining if you set it,
5, Notice the half reward period information
Because the half reward time is coming in 2020, there will be a chance or a risk for it. Many low hashrate machine may be out of the style and high hashrate will be more competitive.
Low your risk and not to buy those cheap machine now
6, Choose a good future crypto currency
There are many coins in this field now, we need to analyse and find a better direction for mining. Like Z11, many people use it for ZEN mining nowadays, and their benefits is top now.
Also, people buy many S17, it can earn money back before next year half reward time. And they believe the BTC price will increase creazily as last two times.
7, Make plan for your selling of coin or machine
As you know, the price of the BTC changes everytime, we can mining the BTC first and keep it in hand, do not sell it every day. It is very stupid. Just sell it when price high, you do not need to take any risk if you do not buy BTC directy. We do not need to care about the low price situation, we only need to wait. When chance come, get it.
Same for machine
8. Don't be fooled by the mining calculator
Many sites calculate mining profits based on hardware and electricity prices. If you've never mined before, you might be happy to see the numbers provided by these websites and calculators and think, "I'll make a fortune!"
However, these websites don't tell you: in addition to the cost of electricity, there may be other current costs, such as maintenance, cooling, rent, labor, etc. Generally, the hash rate and power consumption of the device are slightly different from what the factory says.
This difference is more common in unpopular brands. You can better understand the actual hash rate and the actual power consumption by watching the miner test video on YouTube. In addition, depending on the distance from the meter to the device and the type of cable used, the power loss from the meter to the device can be as high as 200 watts.
In addition to the cost of mining machines, some initial costs are required to prepare the infrastructure, such as cooling and venting, cabling and distribution, shelves, network and monitoring equipment, safety measures, etc.
The network difficulty is constantly changing and increasing at a significant speed, which directly affects the mining revenue. You can check the bitcoin network difficulty chart to see its growth rate, but your miner will not always be 100% active.
Due to maintenance, network problems, ore pool problems, power problems and many other problems, the miner may be offline for several hours. I suggest that you consider setting the normal operation time of the miner to less than 97% when calculating. We have rich mining experience in professional ore pools, and the normal operation time of these mining machines will not exceed 97-98%.
Thats all, hope those information will help you become a good mining investor.

How to prove you are a time traveler using the bitcoin blockchain

It turns out there are more applications of bitcoin than simply revolutionizing every economic system ever conceived.
It is also possible to prove you traveled through time with the help of the hashing mechanism behind our favorite blockchain.
As a thought experiment, consider the following calculation:
Now, if you as a civilization are able to use the energy of your host star, that makes you a type II civilization on the Kardashev scale.
My challenge to the universe and its type II civilization time travelers is simple:
Produce an empty block with around 32 leading zeros in the coming year and we’ll take notice.

Transcript of discussion between an ASIC designer and several proof-of-work designers from #monero-pow channel on Freenode this morning

[08:07:01] lukminer contains precompiled cn/r math sequences for some blocks: https://lukminer.org/2019/03/09/oh-kay-v4r-here-we-come/
[08:07:11] try that with RandomX :P
[08:09:00] tevador: are you ready for some RandomX feedback? it looks like the CNv4 is slowly stabilizing, hashrate comes down...
[08:09:07] how does it even make sense to precompile it?
[08:09:14] mine 1% faster for 2 minutes?
[08:09:35] naturally we think the entire asic-resistance strategy is doomed to fail :) but that's a high-level thing, who knows. people may think it's great.
[08:09:49] about RandomX: looks like the cache size was chosen to make it GPU-hard
[08:09:56] looking forward to more docs
[08:11:38] after initial skimming, I would think it's possible to make a 10x asic for RandomX. But at least for us, we will only make an ASIC if there is not a total ASIC hostility there in the first place. That's better for the secret miners then.
[08:13:12] What I propose is this: we are working on an Ethash ASIC right now, and once we have that working, we would invite tevador or whoever wants to come to HK/Shenzhen and we walk you guys through how we would make a RandomX ASIC. You can then process this input in any way you like. Something like that.
[08:13:49] unless asics (or other accelerators) re-emerge on XMR faster than expected, it looks like there is a little bit of time before RandomX rollout
[08:14:22] 10x in what measure? $/hash or watt/hash?
[08:14:46] watt/hash
[08:15:19] so you can make 10 times more efficient double precisio FPU?
[08:16:02] like I said let's try to be productive. You are having me here, let's work together!
[08:16:15] continue with RandomX, publish more docs. that's always helpful.
[08:16:37] I'm trying to understand how it's possible at all. Why AMD/Intel are so inefficient at running FP calculations?
[08:18:05] midipoet ([email protected]/web/irccloud.com/x-vszshqqxwybvtsjm) has joined #monero-pow
[08:18:17] hardware development works the other way round. We start with 1) math then 2) optimization priority 3) hw/sw boundary 4) IP selection 5) physical implementation
[08:22:32] This still doesn't explain at which point you get 10x
[08:23:07] Weren't you the ones claiming "We can accelerate ProgPoW by a factor of 3x to 8x." ? I find it hard to believe too.
[08:30:20] sure
[08:30:26] so my idea: first we finish our current chip
[08:30:35] from simulation to silicon :)
[08:30:40] we love this stuff... we do it anyway
[08:30:59] now we have a communication channel, and we don't call each other names immediately anymore: big progress!
[08:31:06] you know, we russians have a saying "it was smooth on paper, but they forgot about ravines"
[08:31:12] So I need a bit more details
[08:31:16] ha ha. good!
[08:31:31] that's why I want to avoid to just make claims
[08:31:34] let's work
[08:31:40] RandomX comes in Sep/Oct, right?
[08:31:45] Maybe
[08:32:20] We need to audit it first
[08:32:31] ok
[08:32:59] we don't make chips to prove sw devs that their assumptions about hardware are wrong. especially not if these guys then promptly hardfork and move to the next wrong assumption :)
[08:33:10] from the outside, this only means that hw & sw are devaluing each other
[08:33:24] neither of us should do this
[08:33:47] we are making chips that can hopefully accelerate more crypto ops in the future
[08:33:52] signing, verifying, proving, etc.
[08:34:02] PoW is just a feature like others
[08:34:18] sech1: is it easy for you to come to Hong Kong? (visa-wise)
[08:34:20] or difficult?
[08:34:33] or are you there sometimes?
[08:34:41] It's kind of far away
[08:35:13] we are looking forward to more RandomX docs. that's the first step.
[08:35:31] I want to avoid that we have some meme "Linzhi says they can accelerate XYZ by factor x" .... "ha ha ha"
[08:35:37] right? we don't want that :)
[08:35:39] doc is almost finished
[08:35:40] What docs do you need? It's described pretty good
[08:35:41] so I better say nothing now
[08:35:50] we focus on our Ethash chip
[08:36:05] then based on that, we are happy to walk interested people through the design and what else it can do
[08:36:22] that's a better approach from my view than making claims that are laughed away (rightfully so, because no silicon...)
[08:36:37] ethash ASIC is basically a glorified memory controller
[08:36:39] sech1: tevador said something more is coming (he just did it again)
[08:37:03] yes, some parts of RandomX are not described well
[08:37:10] like dataset access logic
[08:37:37] RandomX looks like progpow for CPU
[08:37:54] yes
[08:38:03] it is designed to reflect CPU
[08:38:34] so any ASIC for it = CPU in essence
[08:39:04] of course there are still some things in regular CPU that can be thrown away for RandomX
[08:40:20] uncore parts are not used, but those will use very little power
[08:40:37] except for memory controller
[08:41:09] I'm just surprised sometimes, ok? let me ask: have you designed or taped out an asic before? isn't it risky to make assumptions about things that are largely unknown?
[08:41:23] I would worry
[08:41:31] that I get something wrong...
[08:41:44] but I also worry like crazy that CNv4 will blow up, where you guys seem to be relaxed
[08:42:06] I didn't want to bring up anything RandomX because CNv4 is such a nailbiter... :)
[08:42:15] how do you guys know you don't have asics in a week or two?
[08:42:38] we don't have experience with ASIC design, but RandomX is simply designed to exactly fit CPU capabilities, which is the best you can do anyways
[08:43:09] similar as ProgPoW did with GPUs
[08:43:14] some people say they want to do asic-resistance only until the vast majority of coins has been issued
[08:43:21] that's at least reasonable
[08:43:43] yeah but progpow totally will not work as advertised :)
[08:44:08] yeah, I've seen that comment about progpow a few times already
[08:44:11] which is no surprise if you know it's just a random sales story to sell a few more GPUs
[08:44:13] RandomX is not permanent, we are expecting to switch to ASIC friendly in a few years if possible
[08:44:18] yes
[08:44:21] that makes sense
[08:44:40] linzhi-sonia: how so? will it break or will it be asic-able with decent performance gains?
[08:44:41] are you happy with CNv4 so far?
[08:45:10] ah, long story. progpow is a masterpiece of deception, let's not get into it here.
[08:45:21] if you know chip marketing it makes more sense
[08:45:24] linzhi-sonia: So far? lol! a bit early to tell, don't you think?
[08:45:35] the diff is coming down
[08:45:41] first few hours looked scary
[08:45:43] I remain skeptical: I only see ASICs being reasonable if they are already as ubiquitous as smartphones
[08:45:46] yes, so far so good
[08:46:01] we kbew the diff would not come down ubtil affter block 75
[08:46:10] yes
[08:46:22] but first few hours it looks like only 5% hashrate left
[08:46:27] looked
[08:46:29] now it's better
[08:46:51] the next worry is: when will "unexplainable" hashrate come back?
[08:47:00] you hope 2-3 months? more?
[08:47:05] so give it another couple of days. will probably overshoot to the downside, and then rise a bit as miners get updated and return
[08:47:22] 3 months minimum turnaround, yes
[08:47:28] nah
[08:47:36] don't underestimate asicmakers :)
[08:47:54] you guys don't get #1 priority on chip fabs
[08:47:56] 3 months = 90 days. do you know what is happening in those 90 days exactly? I'm pretty sure you don't. same thing as before.
[08:48:13] we don't do any secret chips btw
[08:48:21] 3 months assumes they had a complete design ready to go, and added the last minute change in 1 day
[08:48:24] do you know who is behind the hashrate that is now bricked?
[08:48:27] innosilicon?
[08:48:34] hyc: no no, and no. :)
[08:48:44] hyc: have you designed or taped out a chip before?
[08:48:51] yes, many years ago
[08:49:10] then you should know that 90 days is not a fixed number
[08:49:35] sure, but like I said, other makers have greater demand
[08:49:35] especially not if you can prepare, if you just have to modify something, or you have more programmability in the chip than some people assume
[08:50:07] we are chipmakers, we would never dare to do what you guys are doing with CNv4 :) but maybe that just means you are cooler!
[08:50:07] and yes, programmability makes some aspect of turnaround easier
[08:50:10] all fine
[08:50:10] I hope it works!
[08:50:28] do you know who is behind the hashrate that is now bricked?
[08:50:29] inno?
[08:50:41] we suspect so, but have no evidence
[08:50:44] maybe we can try to find them, but we cannot spend too much time on this
[08:50:53] it's probably not so much of a secret
[08:51:01] why should it be, right?
[08:51:10] devs want this cat-and-mouse game? devs get it...
[08:51:35] there was one leak saying it's innosilicon
[08:51:36] so you think 3 months, ok
[08:51:43] inno is cool
[08:51:46] good team
[08:51:49] IP design house
[08:51:54] in Wuhan
[08:52:06] they send their people to conferences with fake biz cards :)
[08:52:19] pretending to be other companies?
[08:52:26] sure
[08:52:28] ha ha
[08:52:39] so when we see them, we look at whatever card they carry and laugh :)
[08:52:52] they are perfectly suited for secret mining games
[08:52:59] they made at most $6 million in 2 months of mining, so I wonder if it was worth it
[08:53:10] yeah. no way to know
[08:53:15] but it's good that you calculate!
[08:53:24] this is all about cost/benefit
[08:53:25] then you also understand - imagine the value of XMR goes up 5x, 10x
[08:53:34] that whole "asic resistance" thing will come down like a house of cards
[08:53:41] I would imagine they sell immediately
[08:53:53] the investor may fully understand the risk
[08:53:57] the buyer
[08:54:13] it's not healthy, but that's another discussion
[08:54:23] so mid-June
[08:54:27] let's see
[08:54:49] I would be susprised if CNv4 ASICs show up at all
[08:54:56] surprised*
[08:54:56] why?
[08:55:05] is only an economic question
[08:55:12] yeah should be interesting. FPGAs will be near their limits as well
[08:55:16] unless XMR goes up a lot
[08:55:19] no, not *only*. it's also a technology question
[08:55:44] you believe CNv4 is "asic resistant"? which feature?
[08:55:53] it's not
[08:55:59] cnv4 = Rabdomx ?
[08:56:03] no
[08:56:07] cnv4=cryptinight/r
[08:56:11] ah
[08:56:18] CNv4 is the one we have now, I think
[08:56:21] since yesterday
[08:56:30] it's plenty enough resistant for current XMR price
[08:56:45] that may be, yes!
[08:56:55] I look at daily payouts. XMR = ca. 100k USD / day
[08:57:03] it can hold until October, but it's not asic resistant
[08:57:23] well, last 24h only 22,442 USD :)
[08:57:32] I think 80 h/s per watt ASICs are possible for CNv4
[08:57:38] linzhi-sonia where do you produce your chips? TSMC?
[08:57:44] I'm cruious how you would expect to build a randomX ASIC that outperforms ARM cores for efficiency, or Intel cores for raw speed
[08:57:48] curious
[08:58:01] yes, tsmc
[08:58:21] Our team did the world's first bitcoin asic, Avalon
[08:58:25] and upcoming 2nd gen Ryzens (64-core EPYC) will be a blast at RandomX
[08:58:28] designed and manufactured
[08:58:53] still being marketed?
[08:59:03] linzhi-sonia: do you understand what xmr wants to achieve, community-wise?
[08:59:14] Avalon? as part of Canaan Creative, yes I think so.
[08:59:25] there's not much interesting oing on in SHA256
[08:59:29] Inge-: I would think so, but please speak
[08:59:32] hyc: yes
[09:00:28] linzhi-sonia: i am curious to hear your thoughts. I am fairly new to this space myself...
[09:00:51] oh
[09:00:56] we are grandpas, and grandmas
[09:01:36] yet I have no problem understanding why ASICS are currently reviled.
[09:01:48] xmr's main differentiators to, let's say btc, are anonymity and fungibility
[09:01:58] I find the client terribly slow btw
[09:02:21] and I think the asic-forking since last may is wrong, doesn't create value and doesn't help with the project objectives
[09:02:25] which "the client" ?
[09:02:52] Monero GUI client maybe
[09:03:12] MacOS, yes
[09:03:28] What exactly is slow?
[09:03:30] linzhi-sonia: I run my own node, and use the CLI and Monerujo. Have not had issues.
[09:03:49] staying in sync
[09:03:49] linzhi-sonia: decentralization is also a key principle
[09:03:56] one that Bitcoin has failed to maintain
[09:04:39] hmm
[09:05:00] looks fairly decentralized to me. decentralization is the result of 3 goals imo: resilient, trustless, permissionless
[09:05:28] don't ask a hardware maker about physical decentralization. that's too ideological. we focus on logical decentralization.
[09:06:11] physical decentralization is important. with bulk of bitnoin mining centered on Chinese hydroelectric dams
[09:06:19] have you thought about including block data in the PoW?
[09:06:41] yes, of course.
[09:07:39] is that already in an algo?
[09:08:10] hyc: about "centered on chinese hydro" - what is your source? the best paper I know is this: https://coinshares.co.uk/wp-content/uploads/2018/11/Mining-Whitepaper-Final.pdf
[09:09:01] linzhi-sonia: do you mine on your ASICs before you sell them?
[09:09:13] besides testing of course
[09:09:45] that paper puts Chinese btc miners at 60% max
[09:10:05] tevador: I think everybody learned that that is not healthy long-term!
[09:10:16] because it gives the chipmaker a cost advantage over its own customers
[09:10:33] and cost advantage leads to centralization (physical and logical)
[09:10:51] you guys should know who finances progpow and why :)
[09:11:05] but let's not get into this, ha ha. want to keep the channel civilized. right OhGodAGirl ? :)
[09:11:34] tevador: so the answer is no! 100% and definitely no
[09:11:54] that "self-mining" disease was one of the problems we have now with asics, and their bad reputation (rightfully so)
[09:13:08] I plan to write a nice short 2-page paper or so on our chip design process. maybe it's interesting to some people here.
[09:13:15] basically the 5 steps I mentioned before, from math to physical
[09:13:32] linzhi-sonia: the paper you linked puts 48% of bitcoin mining in Sichuan. the total in China is much more than 60%
[09:13:38] need to run it by a few people to fix bugs, will post it here when published
[09:14:06] hyc: ok! I am just sharing the "best" document I know today. it definitely may be wrong and there may be a better one now.
[09:14:18] hyc: if you see some reports, please share
[09:14:51] hey I am really curious about this: where is a PoW algo that puts block data into the PoW?
[09:15:02] the previous paper I read is from here http://hackingdistributed.com/2018/01/15/decentralization-bitcoin-ethereum/
[09:15:38] hyc: you said that already exists? (block data in PoW)
[09:15:45] it would make verification harder
[09:15:49] linzhi-sonia: https://the-eye.eu/public/Books/campdivision.com/PDF/Computers%20General/Privacy/bitcoin/meh/hashimoto.pdf
[09:15:51] but for chips it would be interesting
[09:15:52] we discussed the possibility about a year ago https://www.reddit.com/Monero/comments/8bshrx/what_we_need_to_know_about_proof_of_work_pow/
[09:16:05] oh good links! thanks! need to read...
[09:16:06] I think that paper by dryja was original
[09:17:53] since we have a nice flow - second question I'm very curious about: has anyone thought about in-protocol rewards for other functions?
[09:18:55] we've discussed micropayments for wallets to use remote nodes
[09:18:55] you know there is a lot of work in other coins about STARK provers, zero-knowledge, etc. many of those things very compute intense, or need to be outsourced to a service (zether). For chipmakers, in-protocol rewards create an economic incentive to accelerate those things.
[09:19:50] whenever there is an in-protocol reward, you may get the power of ASICs doing something you actually want to happen
[09:19:52] it would be nice if there was some economic reward for running a fullnode, but no one has come up with much more than that afaik
[09:19:54] instead of fighting them off
[09:20:29] you need to use asics, not fight them. that's an obvious thing to say for an asicmaker...
[09:20:41] in-protocol rewards can be very powerful
[09:20:50] like I said before - unless the ASICs are so useful they're embedded in every smartphone, I dont see them being a positive for decentralization
[09:21:17] if they're a separate product, the average consumer is not going to buy them
[09:21:20] now I was talking about speedup of verifying, signing, proving, etc.
[09:21:23] they won't even know what they are
[09:22:07] if anybody wants to talk about or design in-protocol rewards, please come talk to us
[09:22:08] the average consumer also doesn't use general purpose hardware to secure blockchains either
[09:22:14] not just for PoW, in fact *NOT* for PoW
[09:22:32] it requires sw/hw co-design
[09:23:10] we are in long-term discussions/collaboration over this with Ethereum, Bitcoin Cash. just talk right now.
[09:23:16] this was recently published though suggesting more uptake though I guess https://btcmanager.com/college-students-are-the-second-biggest-miners-of-cryptocurrency/
[09:23:29] I find it pretty hard to believe their numbers
[09:24:03] well
[09:24:09] sorry, original article: https://www.pcmag.com/news/366952/college-kids-are-using-campus-electricity-to-mine-crypto
[09:24:11] just talk, no? rumors
[09:24:18] college students are already more educated than the average consumer
[09:24:29] we are not seeing many such customers anymore
[09:24:30] it's data from cisco monitoring network traffic
[09:24:33] and they're always looking for free money
[09:24:48] of course anyone with "free" electricity is inclined to do it
[09:24:57] but look at the rates, cannot make much money
[09:26:06] Ethereum is a bloated collection of bugs wrapped in a UI. I suppose they need all the help they can get
[09:26:29] Bitcoin Cash ... just another get rich quick scheme
[09:26:38] hmm :)
[09:26:51] I'll give it back to you, ok? ha ha. arrogance comes before the fall...
[09:27:17] maye we should have a little fun with CNv4 mining :)
[09:27:25] ;)
[09:27:38] come on. anyone who has watched their track record... $75M lost in ETH at DAO hack
[09:27:50] every smart contract that comes along is just waiting for another hack
[09:27:58] I just wanted to throw out the "in-protocol reward" thing, maybe someone sees the idea and wants to cowork. maybe not. maybe it's a stupid idea.
[09:29:18] linzhi-sonia: any thoughts on CN-GPU?
[09:29:55] CN-GPU has one positive aspect - it wastes chip area to implement all 18 hash algorithms
[09:30:19] you will always hear roughly the same feedback from me:
[09:30:52] "This algorithm very different, it heavy use floating point operations to hurt FPGAs and general purpose CPUs"
[09:30:56] the problem is, if it's profitable for people to buy ASIC miners and mine, it's always more profitable for the manufacturer to not sell and mine themselves
[09:31:02] "hurt"
[09:31:07] what is the point of this?
[09:31:15] it totally doesn't work
[09:31:24] you are hurting noone, just demonstrating lack of ability to think
[09:31:41] what is better: algo designed for chip, or chip designed for algo?
[09:31:43] fireice does it on daily basis, CN-GPU is a joke
[09:31:53] tevador: that's not really true, especially in a market with such large price fluctuations as cryptocurrency
[09:32:12] it's far less risky to sell miners than mine with them and pray that price doesn't crash for next six months
[09:32:14] I think it's great that crypto has a nice group of asicmakers now, hw & sw will cowork well
[09:32:36] jwinterm yes, that's why they premine them and sell after
[09:32:41] PoW is about being thermodynamically and cryptographically provable
[09:32:45] premining with them is taking on that risk
[09:32:49] not "fork when we think there are asics"
[09:32:51] business is about risk minimization
[09:32:54] that's just fear-driven
[09:33:05] Inge-: that's roughly the feedback
[09:33:24] I'm not saying it hasn't happened, but I think it's not so simple as saying "it always happens"
[09:34:00] jwinterm: it has certainly happened on BTC. and also on XMR.
[09:34:19] ironically, please think about it: these kinds of algos indeed prove the limits of the chips they were designed for. but they don't prove that you cannot implement the same algo differently! cannot!
[09:34:26] Risk minimization is not starting a business at all.
[09:34:34] proof-of-gpu-limit. proof-of-cpu-limit.
[09:34:37] imagine you have a money printing machine, would you sell it?
[09:34:39] proves nothing for an ASIC :)
[09:35:05] linzhi-sonia: thanks. I dont think anyone believes you can't make a more efficient cn-gpu asic than a gpu - but that it would not be orders of magnitude faster...
[09:35:24] ok
[09:35:44] like I say. these algos are, that's really ironic, designed to prove the limitatios of a particular chip in mind of the designer
[09:35:50] exactly the wrong way round :)
[09:36:16] like the cache size in RandomX :)
[09:36:18] beautiful
[09:36:29] someone looked at GPU designs
[09:37:31] linzhi-sonia can you elaborate? Cache size in RandomX was selected to fit CPU cache
[09:37:52] yes
[09:38:03] too large for GPU
[09:38:11] as I said, we are designing the algorithm to exactly fit CPU capabilities, I do not claim an ASIC cannot be more efficient
[09:38:16] ok!
[09:38:29] when will you do the audit?
[09:38:35] will the results be published in a document or so?
[09:38:37] I claim that single-chip ASIC is not viable, though
[09:39:06] you guys are brave, noone disputes that. 3 anti-asic hardforks now!
[09:39:18] 4th one coming
[09:39:31] 3 forks were done not only for this
[09:39:38] they had scheduled updates in the first place
[09:48:10] Monero is the #1 anti-asic fighter
[09:48:25] Monero is #1 for a lot of reasons ;)
[09:48:40] It's the coin with the most hycs.
[09:48:55] mooooo
[09:59:06] sneaky integer overflow, bug squished
[10:38:00] p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has joined #monero-pow
[11:10:53] The convo here is wild
[11:12:29] it's like geo-politics at the intersection of software and hardware manufacturing for thermoeconomic value.
[11:13:05] ..and on a Sunday.
[11:15:43] midipoet: hw and sw should work together and stop silly games to devalue each other. to outsiders this is totally not attractive.
[11:16:07] I appreciate the positive energy here to try to listen, learn, understand.
[11:16:10] that's a start
[11:16:48] <-- p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has quit (Quit: Leaving)
[11:16:54] we won't do silly mining against xmr "community" wishes, but not because we couldn'd do it, but because it's the wrong direction in the long run, for both sides
[11:18:57] linzhi-sonia: I agree to some extent. Though, in reality, there will always be divergence between social worlds. Not every body has the same vision of the future. Reaching societal consensus on reality tomorrow is not always easy
[11:20:25] absolutely. especially at a time when there is so much profit to be made from divisiveness.
[11:20:37] someone will want to make that profit, for sure
[11:24:32] Yes. Money distorts.
[11:24:47] Or wealth...one of the two
[11:26:35] Too much physical money will distort rays of light passing close to it indeed.

DISC may be a better choice if you didn’t seize the opportunity of Bitcoin

DISC may be a better choice if you didn’t seize the opportunity of Bitcoin
https://preview.redd.it/di9avv4gqx441.png?width=1211&format=png&auto=webp&s=eb92d1eaffc52764bfd4bb0f0c55dead94aabf26
At present, the mainstream consensus mechanism of the encryption world is the Proof of Work (POW) used by Bitcoin (BTC) and the Proof of Stake (POS) used by EOS. In addition, there are more than 30 kinds of consensus mechanisms such as Proof of Capacity (POC) in the encryption world. Among them, POC has caused extensive discussion. Together with POC, there is also the cryptocurrency Diskcoin in the POC ecosystem, a core algorithm based on POC, which aims to establish a cryptocurrency of a greener energy-saving mining system.
Before introducing POC and Diskcoin, you need to understand POW and BTC first.

Proof Of Work
Ten years ago, Satoshi Nakamoto took the POW into the BTC mining, which once brought more than 200 billion US dollars in economic value to human society. BTC can sit on the throne of the encrypted world, and POW is indispensable. The BTC changed the traditional business model and the role of “miners” was born.
With the development, the miners gradually increased and the competition more fierce. There are large miners, mining pools, mines and other organizations. Due to the emergence of these organizations, the limitations of BTC have gradually emerged. BTC is proud of its decentralization and is no longer decentralized.
At the same time, POW was gradually occupied by ASIC. More and more mining machine manufacturers began to participate in mining. The reward of mining was slowly monopolized by giants such as mining machine manufacturers and mining pools, and small miners lost the opportunity to compete on the same stage.
BTC has been labeled as a privileged label, and now, without enough assets, it is almost impossible to participate in BTC.

Proof Of Capacity
The original intention of Satoshi Nakamoto to design BTC is that everyone can participate in mining and participate in the casting of “currency”. Therefore, in the early BTC mining, only one ordinary computer was needed for calculation work. Now, if you want to use a computer to mine BTC, it is simply a dream. The mining is mainly based on GPU and ASIC mining machines. This makes the cost of mining and the difficulty of mining greatly increase. Most of the hashrate of the BTC full net has been controlled by a few mining pools.
Power energy is also consumed in large quantities. BTC currently has a total hashrate of 43.42EH/S. It is mainly based on the popular S9 ant mining machine currently on the market. The average S9 hashrate is 13TH/S. The converted BTC full net hashrate is equivalent to 3.34 million S9 mining machines! In use, the power of the S9 is 1500 watts, and the power consumption per day is 36 watts. The power consumption of one S9 per month is 1080 watts. If multiplied by 3.34 million machines, the power consumption of the BTC for one year up to 43.2 billion degrees! The BTC full net has consumed more than 159 countries a year, accounting for 0.2% of global electricity consumption!
Can the BTC face a new solution?
At this point, POC boarded the stage of the encrypted world and launched a competition with POW.

Principle of Proof Of Capacity
Before the mining starts, the POC will calculate in advance and the hash value calculated by shabal256 will be stored in the hardisk. This process is called Plotting.
The POC uses a hash algorithm called shabal256. Compared to the B256 sha256, the shabal256 algorithm requires a longer calculation and workload. The benefit of Shabal256 is that miners do not need to perform hash calculations during mining, so the verification process will be relatively fast, and shabal256 will also prevent cheating.
From this we can know that the energy consumption of POC mining is extremely small. Because the repetitive and large amount of calculations are required compared to the POW, the POC simply scans the stored data.
In order to make everyone understand the POC hard drive mining, I will give you a simple example. POC mining process is similar to the lottery in the hardisk, and the process of mining is that you only need to wait for the lottery to draw the prize, you will scan the lottery in the hardisk to confirm whether it is winning, nothing more.
Someone here may have doubts, will it be faster to use an SSD hard drive? The clear answer is, no. Because the POC only cares the capacity of the hardisk, the larger the capacity is, the more lottery tickets you store on the hardisk, the greater the probability that you win the prize, and this has nothing to do with what kind of hardisk you use, what brand of hardisk.
The POC has changed the traditional mining method, which not only reduces the energy consumption of mining, but also lower the threshold of mining, so that everyone can participate.

Diskcoin
Diskcoin, referred to as DISC. DISC, like Bitcoin, has a total of 21 million. Based on the consensus of hardisk capacity, DISC lowers the participation threshold and allows more participation in the casting of coins, which is more conducive to the realization of decentralization.
DISC uses an upgraded version of the POC algorithm - CPOC Conditioned Proof Of Capacity.
Miners need to Stake Diskcoin to get the most reward. The ratio of Staking is not fixed or gradually reduced. Instead, an algorithmic mechanism called DES (Dynamic Equilibrium Staking) is used to adjust the Staking ratio based on the difficulty of mining. DISC's Staking economy model makes it impossible for miners to sell tokens without restrictions. This initiative is also to maintain the healthy and stable development of the DISC ecosystem.
Supply and demand are very important in economics. Supply and demand are the most direct factors for the decline in commodity prices, and the most effective market feedback. DISC's economic model ensures that the circulation of its currency is stable, keeping it in balance with the number of markets.
CPoC mining combines miners with the entire ecological interests, and replaces the originally consumed power resources with tokens as new production materials, so that the entire ecosystem of DISC continues to expand independently, forming a virtuous cycle system.

The entire Nano network is so efficient that, operating at 7000tps, it can be powered by a single wind turbine.

I haven't seen kWh figures but here's a back-of-the-napkin estimate:
Consumer PCs apparently use between 50 and 200W. Let's average that to 100W or 0.1kW [1].
The Argon2 proof-of-work generated per block is typically said to take 2 seconds on a consumer device, or 0.0555Wh per block @ 100 Watts (100 * 1/3600 * 2).
2 blocks (one send and one receive) are generated per transaction, which requires 2 proof-of-work calculations total for 2*0.0555 = 0.111Wh per transaction.
At the scale of 7000 transactions per second this would be 0.111 * 7000 = 778Wh * 3600 = 2.8MWh for an hour of running at 7000tps. If my math is correct, this global transaction load of energy can be produced by a single 3MW wind turbine [3].
By contrast, "the Bitcoin network is consuming power at an annual rate of 32TWh—about as much as Denmark. By the site's calculations, each Bitcoin transaction consumes 250kWh, enough to power homes for nine days" [2].
Again, if my math is correct (I don't work in the energy sector), the cost of 12 Bitcoin transactions (3MWh) can power the Nano network for an hour at 7000tps.
EDIT: This turbine (Vestas V90-3MW) in particular is rated at 3MW. The Quora source [3] is less specific.
EDIT 2: Oops, 6 -> 12 Bitcoin transactions. 250kWh*12 = 3MWh.
EDIT 3: I messed up the wording of Watts and Watt-hours, but the math still works out AFAIK. Thanks erremermberderrnit! (0.111Wh per transaction * 7000 = 778Wh for one second of operation at 7000tps. An hour of operation is 778Wh * 3600 = 2.8MWh which is what a 3MW turbine can produce in one hour.)

Is CPU mining XMR feasible still?

I read an article that XMR could be mined with both CPU and GPUs. Would I be earning much with a single i5 6500 CPU?
Edit: Hey this community is super cool, thanks for all the replies.

I made a nano PoW measurement

https://drive.google.com/file/d/1QLHJvFm0p1K97F7QwkxqMLJS9IfRbt4G
In the last days there were several posts about the costs of nanos proof of work.
u/davey1211 mentioned the site isnanogreenyet.com where it is about the costs of nanos proof of work. The owner of the site calculates the work assuming that a pc needs around 100 watts. This value seemed very high to me, as I assumed that a computer would already need 100 watts in "standby" (not the power saving sleeping stuff, just the "I'm powered on while doing nothing thing"). So this calculation would include the operating system, the hard disks, possibly the monitor and other software. But we want to know how much the PoW of nano costs.

Well, I figured it out

Im having an Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz, 4 cores and 8 logical processors**.**

Intel Power Gadget

My first idea was to measure directly at the power socket and record this somehow. Fortunately, there is a tool from Intel to read this data. Intel Power Gadget. This tool can be downloaded here (for Linux and macOS as well): https://software.intel.com/en-us/articles/intel-power-gadget-20

The Test

I powered my pc - it's a plain windows 10 x64 installation with only nano desktop node v13 and kaspersky on it. So no other services are coming up after boot. I launched my nano desktop node v13, waited for sync and according to the "Intel Power Gadget", my i7 cpu needed about** 20 watts while doing "nothing**". I ran the logging function within the "Intel Power Gadget" and recorded the measurement every 100ms to a file (csv file below). After this, I made some test transactions. The values were always identical.

Results

According to the log, the value "Processor Power_0(Watt)" rises during the PoW from ~20 watts to ~100 watts for approximately ~3.3 seconds. I was very surprised that these values are this high, as mobile phones should also be able to solve this PoW. I recognized that all the values mentioned on isnanogreenyet.com are correct. To sum it up, all nano transactions being done so far, caused ~500kWh in total!! Thats almost nothing compared to bitcoin and even not if compared to one single household. I hope this test gives some idea of how much of the effort nanos PoW calculations actually take. Although the PoW difficulty is higher than I would have estimated, it also provides good protection against spam attacks. In this regard, I am now completely calm.
The detailed values (consumption by cpu only)
- Average watts in standby: 20.17
- Average watts during PoW: 93.35
- PoW watts: 73.18
- PoW duration: 3.39 seconds
- Pow costs: 0.069 Wh - Pow costs: 0.000069 kWh
Thx to antihero12 as I fatfingered kWh instead of Wh

How Much Per kWh Can Bitcoin Mining Make?

Due to an oversized solar array, I have about 10 kW of unused energy per hour during daylight hours. How much can you make per kWh in Bitcoin assuming your electrical cost is zero?
If part of that answer is "it depends on your mining hardware" then could someone supply a table showing the current market cost for each kind of miner and the expected power draw in kW of each model? Which mining hardware would give the most mining power per dollar spent?
This mining profitability calculator seems to give the main variables. https://www.coinwarz.com/calculators/bitcoin-mining-calculato?h=23000.00&p=1541.00&pc=0.0&pf=0.00&d=5106422924659.82000000&r=12.50000000&er=3895.50000000&hc=0.00 Do I just need to plug in my expected hash rate, energy consumption in watts, and electrical cost of zero?
This article seems to suggest that in Jan 2018 the break-even price was $3900 per bitcoin, which corresponded to an electrical cost of 3 cents per kWh. https://medium.com/@hodlmodel/breakeven-price-of-btc-mining-i-bitmains-49-hashrate-694a5699fa37 Obviously that was a different world than today, but I wonder if things would be migrating - when bitcoin pricing is falling sharply - towards that break-even electrical cost of 3 cents per kWh. If yes, mining bitcoin with the available free electricity seems like a poor investment.

Are New Bitmains’ ASIC Devices Profitable?

Are New Bitmains’ ASIC Devices Profitable?
You might have heard that Bitmain has announced the next generation Antminer ASIC mining devices.These devices (S17+ and T17+) are expected to deliver higher hash rates while keeping relatively comparable energy consumption rates.
Bitmain stays true to itself and regularly releases new hardware on its Antminer line. Usually, their products are the top ones on the market in terms of hash rate, but it’s always just a matter of time until the competition catches up.

https://preview.redd.it/131m5wm3wgu31.png?width=1920&format=png&auto=webp&s=f96ef5ad457b46ec058849117432921c2da4821e
Also, there is another problem with third-parties pre-empting the devices and then reselling them at a much higher price. One can only hope that this time Bitmain manages to deliver a reasonable amount of devices.
This time, Bitmain is releasing two devices: S17+ with a hashrate of 72 TH/s that is consuming around 2,920 watts of power and an ‘economy class’ T17+ with 64 TH/s and 3,200 watts of power consumption.

What’s the Profit?

So how profitable it is to run one of these devices considering the current state of market? According to Blockonomi’s calculations, S17+ is profitable to operate, but if you’re hoping for big wins, that’s not going to happen. Assuming an electricity price of $0.10 per kilowatt and running your device for 24/7 for an entire year (no change in difficulty considered) you can expect to earn about half a bitcoin. However at the end of the day, it all comes down to electricity costs.
As for T17+, you could get about 0.45156798 BTC, at the cost of $2,8 in electricity fees.

Is it worth it?

Like everything in the crypto space, this is very hard to predict.
Once these devices hit the market, they will set the hash rate standard, which means increasing network difficulty and lowering the efficiency of the hardware.
Moreover, the bitcoin prices have been bouncing around the $7,500 to $8,000 mark for a while, and if your goal is to sell all of the bitcoin you’ve mined right away, you would probably be able just to cover the equipment and electricity cost after one year but nothing more.
If you are determined that ASIC mining is your thing, it can be a good idea to buy one of these devices but avoid purchasing it from the resellers.

The Bottom Line

No matter which equipment you decide to go with, you can use CoinFly to increase your profits.
We offer you an opportunity to mine the most profitable currency and optimize the mining profit automatically: once the situation on the market changes, the system will just switch to mining the most profitable coin, thus, you will have the possibility to tune your hardware online to achieve optimal performance.

Technical Cryptonight Discussion: What about low-latency RAM (RLDRAM 3, QDR-IV, or HMC) + ASICs?

The Cryptonight algorithm is described as ASIC resistant, in particular because of one feature:
A megabyte of internal memory is almost unacceptable for the modern ASICs. 
EDIT: Each instance of Cryptonight requires 2MB of RAM. Therefore, any Cryptonight multi-processor is required to have 2MB per instance. Since CPUs are incredibly well loaded with RAM (ie: 32MB L3 on Threadripper, 16 L3 on Ryzen, and plenty of L2+L3 on Skylake Servers), it seems unlikely that ASICs would be able to compete well vs CPUs.
In fact, a large number of people seem to be incredibly confident in Cryptonight's ASIC resistance. And indeed, anyone who knows how standard DDR4 works knows that DDR4 is unacceptable for Cryptonight. GDDR5 similarly doesn't look like a very good technology for Cryptonight, focusing on high-bandwidth instead of latency.
Which suggests only an ASIC RAM would be able to handle the 2MB that Cryptonight uses. Solid argument, but it seems to be missing a critical point of analysis from my eyes.
What about "exotic" RAM, like RLDRAM3 ?? Or even QDR-IV?

QDR-IV SRAM

QDR-IV SRAM is absurdly expensive. However, its a good example of "exotic RAM" that is available on the marketplace. I'm focusing on it however because QDR-IV is really simple to describe.
QDR-IV costs roughly $290 for 16Mbit x 18 bits. It is true Static-RAM. 18-bits are for 8-bits per byte + 1 parity bit, because QDR-IV is usually designed for high-speed routers.
QDR-IV has none of the speed or latency issues with DDR4 RAM. There are no "banks", there are no "refreshes", there are no "obliterate the data as you load into sense amplifiers". There's no "auto-charge" as you load the data from the sense-amps back into the capacitors.
Anything that could have caused latency issues is gone. QDR-IV is about as fast as you can get latency-wise. Every clock cycle, you specify an address, and QDR-IV will generate a response every clock cycle. In fact, QDR means "quad data rate" as the SRAM generates 2-reads and 2-writes per clock cycle. There is a slight amount of latency: 8-clock cycles for reads (7.5nanoseconds), and 5-clock cycles for writes (4.6nanoseconds). For those keeping track at home: AMD Zen's L3 cache has a latency of 40 clocks: aka 10nanoseconds at 4GHz
Basically, QDR-IV BEATS the L3 latency of modern CPUs. And we haven't even begun to talk software or ASIC optimizations yet.

CPU inefficiencies for Cryptonight

Now, if that weren't bad enough... CPUs have a few problems with the Cryptonight algorithm.
  1. AMD Zen and Intel Skylake CPUs transfer from L3 -> L2 -> L1 cache. Each of these transfers are in 64-byte chunks. Cryptonight only uses 16 of these bytes. This means that 75% of L3 cache bandwidth is wasted on 48-bytes that would never be used per inner-loop of Cryptonight. An ASIC would transfer only 16-bytes at a time, instantly increasing the RAM's speed by 4-fold.
  2. AES-NI instructions on Ryzen / Threadripper can only be done one-per-core. This means a 16-core Threadripper can at most perform 16 AES encryptions per clock tick. An ASIC can perform as many as you'd like, up to the speed of the RAM.
  3. CPUs waste a ton of energy: there's L1 and L2 caches which do NOTHING in Cryptonight. There are floating-point units, memory controllers, and more. An ASIC which strips things out to only the bare necessities (basically: AES for Cryptonight core) would be way more power efficient, even at ancient 65nm or 90nm designs.

Ideal RAM access pattern

For all yall who are used to DDR4, here's a special trick with QDR-IV or RLDRAM. You can pipeline accesses in QDR-IV or RLDRAM. What does this mean?
First, it should be noted that Cryptonight has the following RAM access pattern:
QDR-IV and RLDRAM3 still have latency involved. Assuming 8-clocks of latency, the naive access pattern would be:
  1. Read
  2. Stall
  3. Stall
  4. Stall
  5. Stall
  6. Stall
  7. Stall
  8. Stall
  9. Stall
  10. Write
  11. Stall
  12. Stall
  13. Stall
  14. Stall
  15. Stall
  16. Stall
  17. Stall
  18. Stall
  19. Read #2
  20. Stall
  21. Stall
  22. Stall
  23. Stall
  24. Stall
  25. Stall
  26. Stall
  27. Stall
  28. Write #2
  29. Stall
  30. Stall
  31. Stall
  32. Stall
  33. Stall
  34. Stall
  35. Stall
  36. Stall
This isn't very efficient: the RAM sits around waiting. Even with "latency reduced" RAM, you can see that the RAM still isn't doing very much. In fact, this is why people thought Cryptonight was safe against ASICs.
But what if we instead ran four instances in parallel? That way, there is always data flowing.
  1. Cryptonight #1 Read
  2. Cryptonight #2 Read
  3. Cryptonight #3 Read
  4. Cryptonight #4 Read
  5. Stall
  6. Stall
  7. Stall
  8. Stall
  9. Stall
  10. Cryptonight #1 Write
  11. Cryptonight #2 Write
  12. Cryptonight #3 Write
  13. Cryptonight #4 Write
  14. Stall
  15. Stall
  16. Stall
  17. Stall
  18. Stall
  19. Cryptonight #1 Read #2
  20. Cryptonight #2 Read #2
  21. Cryptonight #3 Read #2
  22. Cryptonight #4 Read #2
  23. Stall
  24. Stall
  25. Stall
  26. Stall
  27. Stall
  28. Cryptonight #1 Write #2
  29. Cryptonight #2 Write #2
  30. Cryptonight #3 Write #2
  31. Cryptonight #4 Write #2
  32. Stall
  33. Stall
  34. Stall
  35. Stall
  36. Stall
Notice: we're doing 4x the Cryptonight in the same amount of time. Now imagine if the stalls were COMPLETELY gone. DDR4 CANNOT do this. And that's why most people thought ASICs were impossible for Cryptonight.
Unfortunately, RLDRAM3 and QDR-IV can accomplish this kind of pipelining. In fact, that's what they were designed for.

RLDRAM3

As good as QDR-IV RAM is, its way too expensive. RLDRAM3 is almost as fast, but is way more complicated to use and describe. Due to the lower cost of RLDRAM3 however, I'd assume any ASIC for CryptoNight would use RLDRAM3 instead of the simpler QDR-IV. RLDRAM3 32Mbit x36 bits costs $180 at quantities == 1, and would support up to 64-Parallel Cryptonight instances (In contrast, a $800 AMD 1950x Threadripper supports 16 at the best).
Such a design would basically operate at the maximum speed of RLDRAM3. In the case of x36-bit bus and 2133MT/s, we're talking about 2133 / (Burst Length4 x 4 read/writes x 524288 inner loop) == 254 Full Cryptonight Hashes per Second.
254 Hashes per second sounds low, and it is. But we're talking about literally a two-chip design here. 1-chip for RAM, 1-chip for the ASIC/AES stuff. Such a design would consume no more than 5 Watts.
If you were to replicate the ~5W design 60-times, you'd get 15240 Hash/second at 300 Watts.

RLDRAM2

Depending on cost calculations, going cheaper and "making more" might be a better idea. RLDRAM2 is widely available at only $32 per chip at 800 MT/s.
Such a design would theoretically support 800 / 4x4x524288 == 95 Cryptonight Hashes per second.
The scary part: The RLDRAM2 chip there only uses 1W of power. Together, you get 5 Watts again as a reasonable power-estimate. x60 would be 5700 Hashes/second at 300 Watts.
Here's Micron's whitepaper on RLDRAM2: https://www.micron.com/~/media/documents/products/technical-note/dram/tn4902.pdf . RLDRAM3 is the same but denser, faster, and more power efficient.

Hybrid Cube Memory

Hybrid Cube Memory is "stacked RAM" designed for low latency. As far as I can tell, Hybrid Cube memory allows an insane amount of parallelism and pipelining. It'd be the future of an ASIC Cryptonight design. The existence of Hybrid Cube Memory is more about "Generation 2" or later. In effect, it demonstrates that future designs can be lower-power and give higher-speed.

Realistic ASIC Sketch: RLDRAM3 + Parallel Processing

The overall board design would be the ASIC, which would be a simple pipelined AES ASIC that talks with RLDRAM3 ($180) or RLDRAM2 ($30).
Its hard for me to estimate an ASIC's cost without the right tools or design. But a multi-project wafer like MOSIS offers "cheap" access to 14nm and 22nm nodes. Rumor is that this is roughly $100k per run for ~40 dies, suitable for research-and-development. Mass production would require further investments, but mass production at the ~65nm node is rumored to be in the single-digit $$millions or maybe even just 6-figures or so.
So realistically speaking: it'd take ~$10 Million investment + a talented engineer (or team of engineers) who are familiar with RLDRAM3, PCIe 3.0, ASIC design, AES, and Cryptonight to build an ASIC.

TL;DR:

Bitcoin Mining Costs Vary by Region
To perform a cost calculation to understand how much power it takes to create bitcoin, first, you’d need to know electricity costs where you live. In 2017, the Crescent Electric Supply Company did a state-by-state breakdown of how much it costs to mine a single bitcoin. Louisiana came in as the cheapest location at $3,224, while Hawaii was the most expensive at $9,483. As of September 2018, bitcoin’s exchange rate was valued at about $6,700 for a single bitcoin, which shows that doing the work in an area where energy costs are very low is important to make the practice worthwhile.
Calculating the Cost
There are lots of different bitcoin mining computers out there, but many companies have focused on Application-Specific Integrated Circuit (ASIC) mining computers, which use less energy to conduct their calculations. Mining companies that run lots of ASIC miners as businesses claim they use one watt of power for every gigahash per second of computing performed when mining for bitcoins.
At this rate, the bitcoin network runs at 342,934,450 watts — roughly 343 megawatts. Calculations based on EIA data reveal that the average U.S. household consumes about 1.2 kilowatts of power, meaning that 343 megawatts would be enough to power 285,833 U.S. homes.
That’s quite a lot of energy — for a frame of reference, that equates to about a third of the homes in San Jose, California. Since 1 watt per gigahash/second is pretty efficient, it’s likely that this is a conservative estimate. Also, a large number of residential users take more power to run their miners.
BITCOIN may be a useful way to send and receive money, but cryptocurrency doesn’t come for free. The community of computer-based miners that create bitcoins uses vast quantities of electrical power in the process. The electric resource-heavy process has led some experts to suggest that bitcoin isn’t very environmentally friendly. Therefore, using SOLAR ENERGY to mine Bitcoin is considered more suitable for people.
