Synchronization in progress. My node can be located on https://bitnodes.io/ if you know the IP, or the hostname. All I did, was just executing ckpool default installation script from here: https://bitbucket.org/ckolivas/ckpool/raw/master/scripts/install-ckpool-solo.sh

[quote]Run Bitcoin Core on your computer for 14 days[/quote]
It is now running since 2025-08-30, so it is not yet 14 days. And it is not my computer, but some VPS, rented by me (well, when I am online, the control can be switched to my PC, and I can use my server as a proxy, but to keep it running 24/7, I use external servers, instead of running everything from home). So, I don't know, if it meets the rules, but I decided to post it anyway, no matter if it will be merited or not.

I don't know, if I should post it "just the next day", or "just before 24 hours", or maybe "the next day, but after 24 hours". We will see. The content is prepared.

As you can see, I am quite close, to reach it. But I am not yet there, and I guess I messed something up. But I don't know yet, what exactly is wrong, and which single field is not set to what it should be.

Feel free to sweep it, if you know the answer.

What else is missing? I don't know yet. I will try to write more code later, I guess that's enough for today.

As I said in other posts: synchronizing a new node can take something like a week. And it didn't change since then. Now, back to ckpool and regtest, it is time to make some changes.

The minimal accepted difficulty is set to 1, instead of 10000. The plan is to make a testnet out of it.

Added pool status and stats per username
========================================

Pool status is here: https://regtest.space/pool.status.txt
Example user: https://regtest.space/users/bc1qpmz0mtmc2ckuu94kmgl7qy8e0jheu5d6favvqa.txt

As you can see, Garlo Nicon tried to mine something. I think others will join too. But for now, each user has to be manually accepted, I will think about automating it later. Of course, the pool works as intended, and everything that you mine, is counted properly. The manual setup is needed only for displaying statistics publicly.

As you can see, everything is valid, but it is not enough. Standardness limits are preventing us from sweeping it. Try to talk with some mining pool, to go further.

It is intentionally left unpublished on forum, to let other newbies earn more merits instead. I am close enough to 1000 merits, so I guess I should stop there.

First tests of mining blocks with stratum
=========================================

Link: https://regtest.space/users/bc1qfgrajdtd49cy20hejervlqx2sndlwwpfrlz7jj.txt

Some statistics:

{
 "hashrate1m": "0",
 "hashrate5m": "0",
 "hashrate1hr": "1.71K",
 "hashrate1d": "3.32M",
 "hashrate7d": "749K",
 "lastshare": 1757882338,
 "workers": 0,
 "shares": 115,
 "bestshare": 886.8777739071105,
 "bestever": 886,
 "authorised": 1757854890,
 "worker": [
  {
   "workername": "bc1qfgrajdtd49cy20hejervlqx2sndlwwpfrlz7jj.0",
   "hashrate1m": "0",
   "hashrate5m": "0",
   "hashrate1hr": "1.71K",
   "hashrate1d": "3.32M",
   "hashrate7d": "749K",
   "lastshare": 1757882338,
   "shares": 115,
   "bestshare": 886.8777739071105,
   "bestever": 886
  }
 ]
}

As you can see, shares are produced correctly. Maybe I will never solo mine any block, but I will definitely try turning that into a testnet.

Mining command
==============

bfgminer -S opencl:auto -o stratum+tcp://regtest.space:3333 -u bc1qfgrajdtd49cy20hejervlqx2sndlwwpfrlz7jj.0 -p x

New address for mining
======================

Please switch to: bc1q57jtr5l69ygrf8updn869ydzmsyxu5s7ut839c
The previous one already received some coins, so let's try something else.
