Thanks for your reply willi!

Totally correct! My last post in 2021 and I membered here since 2016 and tried several ways for living and mined nearly 2 years with S7 antminer.

And writing in forum and asking about donation was my last chance!

Thanks again!

hello everyone! please tell me if I can set a fixed difficulty on the miner? since port 3333 automatically selects the difficulty for the miner, and port 4334 outputs a difficulty of 1M. I'm mining on port 3333. I tried setting the value d=250000 instead of the password, but the difficulty is still the one that the pool gave out. maybe I need to write to a friend somehow? why am I asking this - the site says for small miners, you can set clien diff=1. if you can set the minimum difficulty, then you can probably set any required difficulty.

[NotFuzzyWarm]

for virtually all miners do NOT set a min diff. Just let the pool figure it out. Setting a min diff is only for toy miners like the original Nerdminers that are horrendously under powered and may not return even 1 share before another block is found when using the default.

[Aleksey183-2411]

so I can't set the minimum difficulty 250000? I have antminers T17 and S19

ausolo.ckpool.org is currently down and undergoing unplanned maintenance, sorry about any inconvenience. As always be sure to have a backup pool specified on your miners. We'll try to get it up as soon as possible.

[-ck]

The ausolo pool issue unfortunately appears that it will be responsible for extended downtime, so I am redirecting the AU domain to the main http://solo.ckpool.org and stats once more. mineracks is trying to rectify it as quickly as possible.

Apologies for the inconvenience.

[-ck]

Now bringing http://ausolo.ckpool.org back online. Miners will likely not come back until their DNS updates and ther mining hardware reconnects. I will kick them back from the main pool within an hour to make sure AU miners go back to the correct pool.

The downtime was due to mineracks trying to fix a connectivity quality issue I detected with the pool which unfortunately caused unexpected downtime. Bear with us as we believe to have addressed all remaining issues, and connectivity should be improved as well.

Hi -ck

Is eusolo.ckpool.org running OK at present, I've been unable to connect all morning.

Thanks

Thanks, I've fixed it. Seems my FTTP router was having a bad day.

Hi!
I've been trying to solo mine on testnet with bfgminer   +ckpool+bitcoind - local.

wrong place to ask this question, go to Luke-jr bfgminer thread here in the forum and ask him.
here you go => https://bitcointalk.org/index.php?topic=877081.msg44351752#msg44351752

Check your Block in a testnet explorer like this:
https://blockstream.info/testnet/nojs/block/00000000003f2e0acdbc702f40f4ab9ebe022add822a18e024644e02ed2f210c

There you can see that it is not your tbtc address:
tb1qhytyuqgw27u4rfhfhck95cap2n8p9tqn6wdu0v   0.23827778 tBTC

thats a result of an outdatet bfgminer used for todays bitcoind, but it should report that its not working.

Unfortunately the topic you provided is archived. I've found another one https://bitcointalk.org/index.php?topic=790323.400 but it seems to be archived too.
Anyway, thanks for the reply. Maybe I need to find another software to try.

One more block solved on solo.ckpool, what a great news!

Sub 1sat/vB transaction discussion and reversal of decision to mine them on solo ckpool.

Block 910440 https://mempool.space/block/00000000000000000000d22167aa0c9d1a49e7878631d6c93ea1b1c87b98ba24 is the first block that solo ckpool has mined that has included sub 1sat/vB transactions. I made this change because the bulk of the mining pools are now mining transactions below the default (until now) mempool policy of mining transactions only 1sat/vB or above. The reason for switching solo ckpool was partially out of necessity - if the mempool differs substantially from what other pools are mining, when other pools mine a block with low fee transactions, solo ckpool will be slow to build new blocks. The reason is because of the disparity in what is in the pool's mempool and it missing transactions included, so it would have to ask for the missing transactions before it can build a full block.

Now that solo ckpool has mined a block with sub 1sat/vB transactions I have data on the reward mined as the result of a low transaction fee period. Of the ~4900 transactions mined in this block, ~3300 were sub 1sat/vB transactions. It took some time to sift through the data of these transactions to determine what the mined fees were. They amounted to ~.0018 BTC more in fees, or ~$220. This is ~.06% of the current 3.125 BTC block reward.

These particular low fee transactions were very small and appeared to create 1-2 UTXOs each.

In light of how ridiculously small the extra fees mined were by accepting these transactions, and the potential for creating a significant number of new UTXOs, I am reversing my decision to mine these transactions. To maintain solo ckpool's ability to be aware of these transactions in the mempool I will only be setting the minrelaytxfee to accept and forward them, but not setting a lower blockmintxfee to mine them.

The block reward needs to have dropped substantially for such low fee transactions to add meaningful reward to mining pools, and I would only consider doing so if the reward was at least 1% more. The block reward would need to have dropped below 0.2 BTC total meaning we are decades away from such fees to be significant. By that time the landscape is likely to be very different to the current one, and it is unknown if fees will remain low that far away. A lower minimum fee is also likely to worsen fees' ability to be a significant contributor to mining rewards as block subsidy diminishes.

I implore other pool owners to do their own calculations and reconsider their decision to mine them at this stage.

[ethanhunt2023]

“A lower minimum fee is also likely to worsen fees' ability to be a significant contributor to mining rewards as block subsidy diminishes.”

That's right, probably the natural solution would be for BTC to rise above $1 million to make it worthwhile.

ck -   i wanted to know if solo.ckpool.org or eusolo accept PSBT on request or if it is only implemented in very special cases for a reasonable price.Thank you.

No sorry, not under any circumstances. Solo doesn't solve enough blocks anyway for it to make sense.

Yes, that's right, I didn't think about that. I think it would be necessary to mine at least 1 block per day.

Hello ck, i totally agree with the Sub 1sat/vB transaction discussion.
But maybe you can include sub-1sat/vb that are beneficial for the UTXO set.
We can clean it up if there is some free space in the block.
If input>2xoutput for example

It's not a bad idea but there's no provision for such a thing in the bitcoin node at present and it would have to be coded up.
