Understand yes my brother, the question is, the result of last week's lottery together with the last few years following logic we came to the conclusion that we can reach the same result from now on, even because we are in 2025 and there is a lot ahead, so based on the experience of the last few years we can believe in seeing more blocks in the ck pool both with small TH or even PH, even because the code and the pool were made for this, that's what it says on the website solo.ckpool.org, even if the solution of blocks with smaller hashes is of a rare nature I believe that this is what will keep hope for those who do not have much hash or even those who have a lot of hash. In other words, the result of the last few years and results from now on will say a lot about the future of the ck pool


Its random, its only ever been random, it will only ever be random.

What happend yesterday has no bearing on what happens today or tomorrow.

so for in order for any of my miners solo mining to hit a block of btc It will have to go above the current bitcoin difficulty of 123.23 T at the time of writing this post?

@ -ck

I'm just wondering what metrics are used to calculate the pool's difficulty level set for a given worker, is it purely down to the number of shares returned in a given time?

Also, how is the difficulty set by a miner? Most of my rigs run CGMiner which has a suggested difficulty parameter '--suggested-diff xxx' that allow me to set the difficulty I want.

However, I've recently added a BitAxe Gamma and there appears to be no method for requesting a particular difficulty so it falls back to whatever the pool decides, is there an additional parameter that can be set for example in the password field like -d = 10000?

Thanks

Cgminer was the only mining software that implemented the stratum command for suggesting diff. Bitaxe and others use different mining software these days, without any support for suggesting diff. The pool chooses based on submission rate to maintain 18 shares per minute. Suggesting diff is by and large a waste of time since the pool will find the optimal value for your mining hardware over enough time, unless you want to set it higher than strictly needed (there's no logical reason for this apart from a very tiny drop in internet bandwidth.) The pool will ignore you setting too low a diff as this potentially acts as a DoS on the pool.


So what is the point of only 18 shares per min?  Surly with such a beefy pool we should be able to sumit way more shares.

Something that has puzzled me about the diff and pools for time is why restrict us to such a low value of share per min.

18 is hardly a drop in the ocean compaird to the power of the server.

If there is no serious load then why limit to 18 shares per min? 

Would this not also have some effect on the time expected for a block?
If you are exected to solve a block when your shares are on par with network diff then it would take approximately 13 million years to submit 123 trillion shares at 18 shares per minute.

That cannot be correct. 



I think you might be confusing shares with the returned hash value

Now, assuming I understand it correctly:-

If for example the pool sets a difficulty of 1000 the miner will only return a share once if finds a hash with a value bigger than 1000.

This doesn't mean its not hashing, it just means its not requesting a new block template until it finds a hash share bigger than the pool difficulty.

Now lets say a really fast miner connects to the pool say 200PH or something like that, if the difficulty was set too low the miner would soon overwhelm the pool with get block template requests as it finds lots of hashes of a low difficulty really quickly and the whole thing would look like a DDOS attack and the pool would stop functioning.

So, the pool then issues the miner with a much higher difficulty in order to slow down the number of requests to a manageable level. The managable level is 18 shares per minute.

The returned value of a share i.e. the hash can be anything within the realms of the total difficulty which I believe is something like 2^96

So by the pool telling the miner not to return shares that have a hash below a given difficulty the number of shares the miner has to submit are reduced, hence the pool manages its resources.

Anyway, I think I have that correct.

Hi -ck

OK thanks for the explanation. I have most of my rigs set with a higher value than the pool requested but not massively different for my fastest rig the pool was requesting something quite low ~3000-4000 for 6TH/s I increased this to 12000 and I found by doing that the average returned share values were higher and as you pointed out it reduced network usage marginally, though insignificant in reality.

It all runs fine, so no issues.

I just wanted to do the same with the BitAxe since it seemed to be hammering the network more than I was expecting, the pool has settled on a diff of 911 for 1.1-1.2TH/s from the BitAxe I think it could do with being a bit higher probably twice that so 1500-1800. Hence my earlier question.

Anyway, its not really a problem just more an observation than anything.

Thanks for your help

G.

Nothing unusual, nor anything of any importance in solo mining.

In solo mining there is only one number that matters and that is the network difficulty.

Okay thank you here is a update since my last post best shares went to over 3B best share from few million which is crazy in just 5 days!

Apparently its completely random.

My rigs typically return shares from a few 1000's to hundreds of millions and on occasion a few in the billions 11.5B 19.2B 49.9B have been my rig's all time best shares.

I've yet to see anything in the Trillions region and my system has been running for over a year.

I've just set-up a new BitAxe Gamma 1.1TH/s and the best that's managed in the past week has been 98.8M

But like I said, it means absolutely nothing and the only number that matters is if it exceeds the network difficulty, then and only then will your miner mine a block and receive the block rewards.

Such is the nature of solo mining.

If you win the lottery, the tax will be from 10 to 45% depending on the country.
In mining, taxes are 0% in my country. I won't tell anyone about this Smiley

I'm literally just using my computer and that's it. But that's good to know thanks for the information. I'll just buy a faster miner over 600 GHS


So if I magically find a block with a slow miner since i never submitted a share I wont get credit for my work or the block reward? I mine for fun and I'm hashing more than a nerd miner and I never submitted a share. I mine to this pool and I'm hashing in the MH's which isn't anything but it's more than those miners you where talking about. What's the minimum hash rate to find shares?  
My understand of the pool even if you don't fine shares you can still find a block? So regardless if you submit shares or not it makes no difference since you're not sharing the block reward with a community of miners
NO! It makes no difference to other folks but you MUST submit shares for a shot at the lottery. If you are trying to use say a Nerdminer (70kHs) and never are able to submit a share because it is a pretty TOY that is far far too slow, there is no way you can 'find a block'.

At a minimum, new work - a new share - is sent to everyone in the pool every time a block is found on the network. In response you must submit at least 1 share back to the pool before the next block is found (on average every 10min). Most folks receive and submit around 18 shares/min. Shares are proof that you have a valid miner that is doing work.
A block ultimately is a high share. The pool FAQ says 100GH minimum. You're wasting your time and the pool's bandwidth with 2010 mining equipment. Your name is also suggestive that you're running a botnet of CPUs mining, and if so - don't do that.

I've just added a BitAxe Gamma to my kit, I must say I'm quite impressed with it. The AXEOS is nicely presented and easy to use.

So, if you're thinking of doing solo mining properly and getting yourself an ASIC miner instead of just burning watts on an old PC for a few hundred KH/s.

I'd recommend a BitAxe Gamma, out of the box 2-3 minutes to set-up and then 1-1.2TH/s performance.

Good luck!

AFAIK, the prune only takes place once the entire block chain has been verified.
Wrong. Pruning takes place on the fly, while downloading new data.

Correct. That's how it verifies all your own transactions.

Is that applicable to a full node as well?

Or does a full node require the entire block chain?

You can set your Bitcoin core to pruned if you don't want to download the whole blockchain.

With so many terahashes flying around, would a fast internet connection be of any help, or an average speed one will do just as well, since everyone has the block that is being worked hn?

I looked up a recent block, it had 18 leading zeroes in the hash that solved it.  18.  The chances of making a hash that fits that criteria are very low.

You won't hit a block without at,least 1ph

That would be four s21xps which cost 7000 each. Or 28000 total

And the odds of hitting that block even with 1ph are still very high.  About 1 per 16 years.

Still even at 1TH/s the odds are better than playing the lottery.

1TH With todays diff, 1 in 6,109,236 per day

The odds of winning the UK's national lottery : 1 in 45,057,474 per game

There's a reason solo mining also has the alternate name of lottery mining.

  10000 s21 =     2eh
100000 s21 =    20eh

so it is 200,000 s21 units off line

or 300,000 s19xp units off line

either way power used drops a lot

about 710,000 kwatts an hour

or 710 megawatts an hour


retool of new gear could be happening

remember weather is warming up in the USA thus mining tends to slow a bit.

We do have a thread for this the 2025 difficulty thread.

Well, yes I thought it might be a large farm switching off somewhere to update or as you say re-tool. I guess if we see it spike back up that'll be some evidence of it but 40EH is a heck of a drop.

Do farms really contain 200,000 units? That in itself is wild. 710MW is about half a nuclear reactors worth.

In terms of power if you think of the total available hashrate it peaked at 0.907 ZetaHash.  Its almost an incomprehensible amount of power usage even if it were averaged out.

I'm sure if it peaks again it'll break the ZetaHash barrier.  Shocked

Mind blowing numbers...

you can only mine on a stratum pool of your choice and enter this in the settings of your bitaxeGamma as follows
the first steps i would take in your place are to carry out the respective updates - you can find them under this link: https://github.com/bitaxeorg/ESP-Miner/releases

where did you buy the bitaxe miner, if you don't mind me asking?


Thanks for the link. I agree getting the latest FW onboard would be a good idea. I've no idea how to do that presently, but I'm sure I'll work it out.

I bought it through ZeusBTC, hopefully that wasn't a mistake.

Anyway, I'm wondering if I can set it up to mine locally to bitcoin core using GBT, or does it only support Stratum protocol and mining to a pool?

I admit I don't know much about BitAxe as of yet, so if anyone knows thanks for your help.

Just an interesting observation.

Since April 17th there's been a massive drop of 40 ExaHash in the global hash rates.

It was what was driving the network difficulty up 6-8% over the past couple of re-calcs.

40EH is huge now its been pulled, I wonder who or what was behind it.

some instances it was over 0.40/kwh....

It still is depending on the supplier, you really have to keep shopping around to get the best deal and try and avoid lock-ins and exit fees.

Octopus energy were about the cheapest on my last revision a couple of months ago, £0.41 daily standing charge and £0.25/KWh

I think British Gas were the worst, IIRC it was round £0.48 daily and £0.31/KWh so around $0.41/KWh

to put it another way.

Doesn't matter who it is, or where they mine BTC to.

If you only have a Bitaxe 601 and are trying to hit a BTC block;  you have a ~0.007% chance of hitting a block in one year.   Anything more or less is just a lucky nonce.  Nothing more, nothing less.

Shares on a solo pool are just a measure of if your miner is still reporting things to the pool... they dont count for anything other than a heartbeat.

If you are doing merged mining (merged pool share mining, not solo);  your shares count for your share of the winnings;  but thats in relation to the difficulty of shares being given.  If your machine is reporting shares at 1,000+ difficulty;  they will be worth less of a cut than the other person's shares being reported at 100,000+ difficulty.  in fact, 100 times less.

See how it works?


BTW;  congrats to the recent pool winner.   I noticed my miner's high diff result reset the day the block was found.    Since I finally bought a house and could afford to;  I finally got and plugged in a lottery machine after all these years of absence.   I moved away from my old spot where I had free power (back when the S7 was brand new, I ran one in my RV for many years all for free).    But hey, power in Wisconsin is not anything compared to the cost of Cali where I was originally at.

You think your electric costs are high. Try living in the UK. $0.33 per KW/h

First question that comes to mind, isn't how many KW you need to make it profitable. With free energy you're already more or less profitable even with a lower hash rate.


The question is how many KW of free energy can it reliably supply and does it have battery backup.

If you're exclusively using solar to power it, expect it to black-out as the sun doesn't always shine.


Once you have a baseline for the amount of power available then you could use one of the many profitability calculators and work out which miner's are likely to return the highest profitability.

Almost certainly that'll be one of the newer Bitmain Antminer S21 series, depending on hash rate and type they're anywhere from around 3500-5500KW each at hash rates of 200T-470T though getting one is like finding chickens teeth.

So you may have to think lower performance and older models, but realistically it hinges on how much power is continuously available.



I run a small rig 6TH/s from solar. Its on a timer and monitor system so it only runs when there's enough spare energy from the panels to meet the house needs and the extra for the mining rig. But it doesnt run 24/7
