The maximum difficulty would be about 2^224, that is unrealistically huge, and the current 90T diff is a tiny fraction of that.

I think it would make sense when you understand what a target is, target is what the logic is built on, we store the target in the block header and not the difficulty, the difficulty is just an easier representation of the target, so mining becomes more difficult when the target is smaller and vice versa, so as silly as it sounds, when you see difficulty goes up, it simply means target went down.

So an easy target would be infinity, which means anything that you guess below infinity would be valid, a difficult target would be 0, which means there is nothing smaller, the lower the target goes the smaller the number of valid hashes.

The current target is
in decimal (more human-readable format) that is
301319254070149585548971905645948786445483268317904896   


The target in the previous epoch was

in decimal
310338180674118587457206844748640968959780028040609792

Notice that the target in the previous epoch was larger (difficulty was lower).

to make things a lot clearer, here is the target of the first block Satoshi mined
in decimal
26959535291011309493156476344723991336010898738574164086137773096960

now since Difficulty= maximum target/given target, if you apply that on the first block it would give you  difficulty of 1 (target was too huge, difficulty was too low, you basically guess anything and get a block ), apply it for the current target and you get 89T

Now if you read the post I quoted in my previous reply, you would understand how it's easier to hash a number that has less leading zero than more, i.e, it's easier to find larger numbers than smaller ones, think of it this way, you have a box that has an infinite number of pieces of paper ranging from 1 to infinity, I tell you if you manage to pick any piece of paper that is smaller than 1000000000000000000000000000000000, I 'l give you the prize, that would certainly be easier than if I told you the number you need is smaller than 10 because then there would be only 9 chances out of the infinite numbers in the box.

I know it's easier to understand difficulty than to understand the target, but really, if you don't understand the target, there will always be missing pieces in your comprehension of how this works, now when you say high share, it's actually a small target share which then translate to a high diff share.

So if you are required to find a number smaller or equal to 1000 and you find 1, then that's a very small target which is a very high diff, so when you see blocks getting a high share they technically found a hash a lot smaller than they had to win a block, so the smallest the target can be would be a 256-bit number, which is just right above 0, so when you ask how high share can be, it can be as high as 2^224.

It should be  "command": "sleep x"  where x is the time in seconds, to do this you will need to authenticate and get the process ID to kill it, google Cgminer API, and you will find many useful websites.


He wants to do it directly without the use of third-party software such as Awesomeiner, all these software use Cgminer API, obviously, in most cases, it's not worth it to write your own code, test it and then troubleshoot it just to control a few miners, which is why Awesomeiner is a great option.

There is no overlapping, the pool provides the blocktemplate, the miner uses different nonce, every minier is randomly hashing a block, unless the miner software is bad and for some reason one miner is duplicating the work of another miner.

You need to understand that mining is not about solvig a formula, it is not incremental, its not that you try
1
2
3
4
And 5 is a block, block could be nonce 1, so thinking you can jump here and there to hit a block faster is wrong.

Give my post a read

T21 is generally a "bad" miner, while I have not personally operated any, I did help some folks acquire them "against my advice", I believe the first batch was the worst one, there seems to be a flaw in the design where the chips in the corners get too hot and eventually fail, many people chose to change thermal paste because they believe that's the main reason why these T21s get very hot.

Obviously, you would still see people who love the T21s, again, it's all about luck and which batch is screwed and which one is not, Bitmain is known for making terrible batches, heck, even an entire product line can be bad like the 17 series especially the T17s, so the reality is, you will get mixed views, very different answers, but someone saying they run T21 just fine doesn't mean everyone will get to say the same thing.

I have had thousands of mining gears run under my hand, be it miners I ran, or bought for clients, I still up to this point don't understand why anyone would choose Antminer over Whatsminer, the little efficiency improvement Bitmain has can never make up for the high failure rate, I had a Whatsminer M21s running alongside dozen Antminer 17 series, in a very hot summer with a single fan and full of dust, the worst it would do is show "over temp error", reboot and start mining, while nearly all of the Antminer experienced issues and some died, generally, you shouldn't run Antminers in hot weather, underclock the shit of them and always make sure the environment temp is no more than 30c or so, if you have Whatsminers, 40c will do just fine.

I suggest you find a good local repair shop and get them to fix your gears (they are usually fixable and it's most of the time just a few chips that go bad, and once you fix them they go on for a good period), sending gears back to Bitmain is usually a waste of time.

If you would share your container design, some of U.S might be able to help you improve cooling, although, if it's freaking hot outside, your best bet would be to underclock for the 2-3 hot summer months.

1% vs 1.3% isn't all that different is it? anyway, rejected shares mainly happen for two reasons:

1- Latency (internet-related issue), this is the most common cause for rejected shares, so check your internet connection, ping the pool with -t option in CMD, let it do 100-200 pings, and check the status.

2- Software/Miner issue: not very common with known ASICs since usually those software versions are heavily tested, whatever new small device you are using could be the issue, check with other folks if they have the same thing.

Also, just so you know, as far as I know, solo.ckpool.org has only one server and it's located in the U.S, so if you happen to be way to far from it, then you are more subject to high latency and thus more rejected shares.

With that said, since you can't do anything about it (unless improve your connection if it turns out to be the issue), I'd just settle with the 1-2% and leave it be.

The way I see it is that the NFT hype is done with, to inscribe an image on the blockchain and hope that people would pay a lot of money for it is probably not going to work again, there should be new things, and most will be a replica of what ETH, I watched a short video of Trump saying good stuff about crypto if he wins, anyone knows what those are (assuming we'd believe he would stick to his words anyway).

I think what could drive BTC transaction fees to something extraordinary for a sustainable period of time would be if large institution settle their final payments on the blockchain, to pay $50 worth for a 5 billion transaction would still be cheap to them and a lot more secure than their average protocol.

1.1m is indeed a huge amount that would certainly affect the price be it done at once or in stages, however, the total daily volume of BTC trades is half a million BTC (today's volume), double the volume in the order book would certainly crash BTC price at least temporary.

However, the greater effect would be the fact that Satoshi's coins are moving, which would cause a massive drop in price for various reasons that the market would speculate.

1- Some people would think Satoshi lost faith in BTC and it's over.
2- Someone managed to "hack" into Satoshis wallet or brute-forced the seed.
3- Satoshi's identity is exposed and some x government arrested him.

Those along with other things that come from a lack of understanding of how Bitcoin and its security work, like Satoshi giving away the "key" to Bitcoin and thus it would be destroyed (many people think there is a source code of some sort that only Satoshi has, like a private server or whatever that would bring BTC down" .

Mostly it's all these negative speculations that would cause a massive drop price, which would then be recovered over time in my opinion.

Ya, that would fix all of their problems.

@NFW,  we battled with noise issues in dozen farms, hired professionals, and tried our own shit, it is most certainly a lot harder in practice that on papers.

It is very simple to stop sound, sound is a form of energy that would stop moving forwad when it meets resistance, you put anything with high density in it's way it would be reduced, up to the point where no human ear could hear it, all those materials in the website you linked are high density (except the ones used for sound dampening which is different from sound proofing) are good and effective.

However, the problem here is that you are not sound proofing a theatre or a studio, it is 300MW worth of heat, anything that would block sound would block heat too, placing the sound proofing walls too far to allow for cooling will reduce sound proofing, placing them too near would block heat.

I am not saying it can't be done at all, I am saying it is a new challenge even professionals in the soundproofing field have not faced before.

I call b.s on this one, it is plain simple if they made a 100k profit in 3 weeks for a $1500 bill + rent which won't be anything near 5k but say the total cost was 10k so 90k profit or 30k per week, they would have rented that house for year, who would leave?

The lady is lying.

Constant noise is probably better, your brain gets used to it and it becomes the norm.

@phill, ya, won't be anywhere near cheap to fix that noise, if they ever have to fix it "which i doubt since there is no law for that" their best bet would be underclocking + reducing the exuast fans.

If the nearest house is 50 meters or so, there will be nothing they can do to help people in that house go to sleep peacefully, at 50 meters even a single miner at 7000 rpm will be clearly heard.

Also, walls, no matter how thick, they won't cut it completely، sound travels at all directions, it would still go up and then back to the direction of the houses.

Thanks.

That is a valid argument but you can counter it by saying BTC provides more than just 400k transactions, it provides self-custody and breaks away from the centralized monetary systems, that is the actual value of Bitcoin and not the number of transactions, it would still be worth as much even if it was doing only half the transactions.

Again, even hot showers are debatable, to someone who has no access to hot water they consider that a waste of energy, but fine, let's exclude all household activities including the non-essentials, how much power do weapon manufacturies use?or those fake-ass expensive brands that only the rich buy, you will find a lot of useless industries that burn a lot more power, but then again, to many others, that won't be useless, so it is all subjective.

As you said, BTC power consumption will be self-reduced over time, there is no need for the crying that anti-bitcoiners perform everyday, some of them lobby against Bitcoin for it's environmental "damage" and don't say a word about all the militiary activites that destroy lands and nations, it is ironic.

It is very easy to manipulate these figures to help draw a certain conclusion; the reality is renewable energy is expensive and not highly available; when companies claim 90% green or renewable energy, they are just lying; maybe they got that figure of 1-day reading.

When mining was done in China, during the rainy season one could easily claim that 99% of bitcoin mining is done using hydropower, but then right after September when the monsoon is over they go back to burning coal like mad, so would result in figures that state miners use 99% coal, you can easily cherry-pick numbers here and there.

One thing we know for sure is that every business owner is a greedy person, Bitcoin mining would work just fine using pens and papers, or an Excel sheet running on a 50w machine, if people start using nuclear bombs to mine it, it doesn't make bitcoin bad, it just proves that people are greedy and governments are corrupt.

The entire worldwide BTC power consumption is about 20GW, and that assumes 30w/th, which is 100% more than the current most efficient gear.

20GW is roughly 175 TWh annually, which is less than 0.5% of the total power the world uses annually; it is a tiny fraction.

If you really want to protest against power waste and pollution, you should start with the military-industrial complex, those guys steal your tax money, polute the air you breath, suck a dozen more energy than BTC does, and directly contribute to the killing of thousands of innocent people.

As for hot showers, it makes no difference, again, this is how it works, every second you spend in the hot shower makes life harder for the next person (applying your logic).
 

That logic applies to every other business and even households, it's like saying you don't want people taking hot showers because that increases power prices or new clothes factories or anything that creates a demand on power, you want to enjoy the benefits of capitalism you should also accept all it's downsides.




It does increase jobs not only in the mining farms, in power plants, distributions, transport, gas/coal mines, oil industry and everything that activates the power coming to those miming farms.


It does in "some cases" as I mentioned earlier, an example would be in remote areas where there is not enough demand for a power plant and people rely on expensive transmission from the nearest source located 1000km away, mining farms would create the required demand for the electric company to build power plants nearby, cut transmission losses and thus lead to lower power cost.

المنتدى بشكل عام في انحدار مستمر منذ العام الماضي، وهدا على صعيد النشاط وليس المضمون.

اعتقد ان هناك سببان رئيسيان لهدا، اولهم نقص الزخم حول البتكوين، لايوجد اخبار جديدة، قمم جديدة، انفجارات سعرية مخالفة للطبيعة، كل شي كما هوا عليه ولايوجد الكثير من الاشياء للحديث عنها.

السبب التاني والاهم هوا حملات التوقيع، قرار المشرف بالرغم من تأيدي له لانه تحت ظغط قانوني الا انه قد ساهم بشكل مباشر في انعدام النشاط في المنتدى، الكسب المادي كان ولا زال عامل اساسي في اي نشاط، لذلك لا اتوقع ان يتغير الحال حتى عودة نشاط حملات التوقيع.

Unless you are too deep into the "green world" concept which I am not into, then power consumption is a net positive to the world, demand on power by bitcoin increases jobs, adds more value to the economy and in some cases even makes power a little cheaper.

You can simply verify the above by checking GDP vs Power consumption for any country, both move together.

As for the noise, it is not all that bad, out of the thousands of farms around, how many of them are stupidly built in a populated area? As for the farm in question, I would blame that State for it, if they can't regulate noise pollution to protect their people, they are dumb as hell, people are greedy by nature, it is not BTC's fault.

Google "hush house" you will find a lot of videos on how they test those F-16S and the like, ya those are not cheap to build, but you build them one time and they don't require that much space, they just one large room that can withstand the pressure and the heat, the exhaust of the Engine is faced towrads a very large like-tube that is relatively pretty small.

Now go have a look at that 300MW farm, thats 100,000 miners, you can't have them all facing a small area that you can control, they need to be spread, each miner can make up to 90db, noise level increases by 10 db everytime you 10x the noise source

1 miner does 90db
10 miners do 100db
1000 miners do 110db
10,000 miners do 120db
100,000 miners do 130db

While that is roughly the same noise an F-35 makes, you just can't contain them as easily, your average miner is 30cm high and 20cm wide so 0.06cm2 , 100k miners will need a at least a total area of 6000m2, that hush house exaust is what, 10m square?

On the phone, can't check which news is actually "news" for Hut 8 mining in Canada, i have also read another article that explains why Canada is no more attractive to miners, will try to find it and share it with you.
