Congratulations to miner bc1qq926qlrhc2pvxzc5f0zswnvqqddqqj3tz2amla with a sizeable 2.5PH/s for solving the first EU solo block and the 298th block at solo.ckpool.org!
https://mempool.space/block/000000000000000000005afed55b551d961220653a05daa8f362de2a384d8cea
A miner of this size has about a one in 2,000 chance if finding a block per day.

Congratulations to a super lucky miner bc1qaxccz85rx6ywy2xw6ugtm6u37mvew6qqn7lgtd with only 3.3TH who solved the 297th solo block at https://solo.ckpool.org with a 480GH bitaxe!

A miner of this size has only less than a 1 in a million chance of finding a block per day, or put alternatively, would take 3500 years to find a block on average.

Update re the EU solo pool. Everyone mining to eusolo.ckpool.org is currently directed to the main pool solo.ckpool.org as it was rapidly decommissioned by the original donor. The new hardware was meant to take 3 days to provision but my provider has already set it up. I'll get to work at deploying the pool as soon as possible.

2025-01-29 05:19:50 GMT

Re: http://eusolo.ckpool.org, sadly the anonymous individual who offered to fund the server's running has retracted their offer. This & the stats incident has confirmed my belief I should not rely on others. I will likely now fund it myself but will need to migrate the service.

Sorry, minor correction: Cgminer was the defacto mining client software, and it's still in use today in some form in most mining hardware. Slush was the first mining pool.

The EU solo ckpool is up and running! Connect to the pool via instructions at http://eusolo.ckpool.org. Graphical stats available at http://eusolostats.ckpool.org. Miners in Europe and Africa are encouraged to move to the new pool. Miners in The Americas and Asia-Pacific should still use http://solo.ckpool.org but the sister pool can be used as backup.
This is an entirely separate pool from http://solo.ckpool.org and neither shares nor stats are shared across instances for overhead reasons. They only help propagate each others' blocks. Both will solve blocks with the same coinbase signature though.

People occasionally ask me what to do about diff and what the high diff port (4334) on solo ckpool is ideal for.
To clarify: the diff you mine at makes absolutely no difference to your chance at finding a block. In addition shares with solo mining have no intrinsic value and are purely for feedback to know you're mining at the pool. The high diff port has a starting diff of one million and is set that high simply because rental mining services demand that high. Only pethahash sized miners should consider using the port if they are consolidating their hashrate through a proxy - otherwise even if you're an exahash sized miner with every discrete miner connecting to the pool you should still use the regular port.
The other question that comes up is whether you can set your diff manually - the answer is yes if you use cgminer directly since I implemented the stratum protocol suggest-diff option within cgminer and ckpool. However again it is of no real use apart from getting the diff closer to matching your hardware earlier on as the pool will automatically adjust with time to an optimal diff (also purely cosmetic) though it may take a while if you're a tiny miner.
The final question is what to do if no hashrate or statistics ever show up on the pool - usually that's because people are mining with ridiculously low hashrates, GPU or CPU miners or most commonly nerdminers. The answer there is - don't do that. Just don't mine with such small hashrates as it's beyond the level of lotto mining into the ludicrously improbable chance of finding a block.

Weirdly people see the ckpool project is 10 years old and think the code is 10 years old when it's actively maintained. I don't support any external ckpool docker containers maintained by anyone else that are out there.
The code as is published, is used directly on solo ckpool:

Theoretical physics has been using dark matter to fill in the gaps in existing theories, yet decades of searching for it has failed to find any proof of it. I find the possibility that the theories are wrong to begin with and need to be reworked compelling as an outsider. It reminds me so much of modern medicine insisting that cholesterol must be the cause of heart disease even if none of the research to date has convincingly demonstrated it because "we just haven't done a good enough study yet." 70 years since it was first proposed isn't long enough?

They claimed they randomly guessed at needing 10x their normal capacity and it exceeded that, instead of doing what any large scale operation would do which is simply implement load-based scaling. Of course it rings of bullshit, but then given how incompetent they are, these guys couldn't get laid in a brothel, so it could well still be just plain incompetence. Either way conbase continue to prove they're enemies of bitcoin, whether it was malice or stupidity.
