It did work? The guide provided above is for Testnet only; if you apply the guide above in Mainnet, I don't think it would work.
Usually you need to run a mining pool because it requires a stratum protocol if you want to mine solo.

Just in case if you want to try running your own pool, you can try any of these below

- https://github.com/tpruvot/yiimp
- https://github.com/jtoomim/p2pool

Or the one provided by -ck posted here https://bitcointalk.org/index.php?topic=790323.0

Correct.
It probably does not support the Compac-F either as the drivers for both were added by Kano just a few years ago for the F and last year for the A1.
Link to Kano's git is in my sig.

btw: that version of cgminer you have is a hacked version and NOT recommended. Amongst other things it adds an extra nonce aka the Golden Nonce. That is a security risk as it allows the miner to switch work to mining other coins without telling you about it...

Hello yoshitmitsu,

you can solo mine on your own full node (bitcoind) without hesitation. Don't be put off by Kano's statements. He is constantly bashing other pool operators because he sees everyone as a rival. As you note, he also doesn't even address your questions that you understandably asked, instead he also attacks you for supposedly promoting the patch that unlocks solo functionality. He doesn't like that thousands of solo-mining enthusiasts out there could mine on their own full-node because that would mean even fewer participants on his pool. As you may know cgminer was developed by Con Kolivas (-Ck) and Kano had participated there as a developer. Kano especially developed the driver parts. CK kicked Kano out many years ago and banned him from development because of personal disputes between the two. Since then, Kano has been constantly ranting on CK and everything that has to do with him. However, this bashing does not exist the other way around. CK stopped the development of cgminer a long time ago and made it public. Kano has been managing cgminer on his own since then and has his own fork at github.com/kanoi/cgminer. There he maintains e.g. the latest drivers, especially those from Gekkoscience. He sees himself as a god, everyone else is a loser in his opinion.

About your questions and your intention. You are of course welcome to apply the golden-guy patch. As it was already suggested to you, you could clone the current cgminer version from Kanos' github repository and then apply the golden-guy patch. As mentioned here in the thread, there are also numerous other github repositories that include this patch, which unlocks solo mining functionality. What you should pay attention to when you manually apply the golden-guy patch --> you must NOT specify a bech32 address (begins with bc1q...) as payout address but you should exclusively use a legacy P2PKH address (begins with 1...). If you would use a bech32 as payout address (eg. bc1qxyz123abc...) then cgminer would seem to run without any problems at first sight, but if you should really hit a block, then the coinbase transaction would be erroneous and the reward would not be transferred to your specified bc1q.... (Bech32) address but to a random bitcoin address. Your reward would be lost, that would be fatal and nobody wants that. This is what Kano means with his incomplete statement and although he knows the risk, he resists to post this information here publicly, so that he can claim himself as a prophet afterwards full of glee (by actions like that). Such behavior is anything but exemplary.

Bech32 didn't exist when CK implemented solo mining in cgminer those times and as explained before cgminer was put in archive mode by CK. Kano still deliberately avoids unlocking solo functionality in his current versions, and he tries to justify this in the sense that it would be foolish to mine on a dedicated full-node. Of course, it should be clear to everyone that a full node and mining on such a full node requires certain minimum requirements and how important performance is in the context of the mining process. A possibly found valid block must finally find its way into the blockchain in the shortest and fastest way and reach many nodes at ultra-fast speed, otherwise one runs the risk of stale shares and orphan blocks. Not only a high-performance full node is important, but also the speed to the Internet plays a role, as well as the routers and hops in between. At best, everything runs in a data center with high-quality devices and top performance with an extremely fast Internet connection. Keep in mind the sheer amount of data (some TBs per month) just for the GBT traffic so running this at a data center makes only sense if your miner is located on-site, too. This information could all be mentioned, explained and ultimately left to the user's free decision to solo-mine on a full-node.

So that you don't do anything wrong when enabling the solo mining functionality and risk misconfiguration, I would highly recommend you to use ready-made cgminer versions that already contain this patch. There are several Github repositories. My own favorite is github.com/phaenomenon/cgminer, which is quite up-to-date (version 4.12.1) and includes many other useful things besides the actual Golden Guy patch. For example, it automatically checks the given payout address for correctness, only then the mining process starts at all. If you accidentally entered a Bech32 for solo mining, cgminer warns you at startup and aborts with an error message so you can correct it. Also, you can mine not only in mainnet but also in testnet. In testnet you need to provide a legacy address that starts with "m" or "n" and this is also handled by the input validation. The README contains useful information under "SOLO mining" and there are also very cool start scripts included, so you can get started right away.

I also highly recommend reading those two How-To's from nullama which explains how to mine on testnet using a GekkoScience Compac-F USB miner or even with a GPU/CPU:
[Guide] Solo mine testnet bitcoins with cgminer, Bitcoin Core, and a Compac F
[Guide] Solo mine testnet bitcoins with bfgminer, Bitcoin Core, and a CPU/GPU

In case you use a GekkoScience Compac F, the installation process is as follows.


Logs are written to the subfolder "logs\" which I find very convenient. After you have successfully mined your first block on testnet and received succesful your block reward, you could switch to mainnet.

Hope this guide is helpful for everyone. Good luck and happy solo-mining

You'll need additional software to perform full mining. You can try following this guide [Guide] Solo mine testnet bitcoins with cgminer, Bitcoin Core, and a Compac F, while changing few parameters in order to use mainnet instead.

Hello all. I hope you've been HALVING a good time mining lately!

(yes, it wasn't funny; no, I won't apologize)

Your old pals at GekkoScience are rolling out more stuff. Our new product for 2024, the first of many if everything works out, is a new stickminer. Of course it is; we always start with new stickminers.

This fellow is called the Compac A1.



If you have figured out the nomenclature of our company and products, you know it's all an homage to Eureka Seven, in which the Amita Drive was attached to Renton's Compac Drive, expanding its abilities. In the same vein, we've added our own Amita Drive of sorts to the Compac A1 (get it?) in the form of built-in telemetry and software control. No longer will you need to reach for a tiny screwdriver to tweak the voltage; it'll be done in software via cgminer commands or the API. And you'll be able to watch the temperature! And the USB bus voltage! And even change how the blinky light blinks! It should be possible to adjust the voltage on the fly, making tuning easy. Should be pretty fun.

There's also an optional 2-pin fan jack for snap-on fans without tying up another USB port. That's a new feature. Resellers will probably have add-on fan packages utilizing this. Please note that the fan jack is spec'd for fan loads only and CANNOT be used as an external 5V power input. You will burn things up by doing this.


This stickminer is built around S19 chips for good efficency, approximately 30% better than the Compac F. Samples have marked Compac F stock speeds around 260GH from under 8 watts.

Another benefit over the Compac F is low-end stability. It's built to handle high speeds, but unlike the F, it won't choke up at low speeds, so you don't have to overclock it on a juiced-up hub just to make it work.

But you can if you want. I've clocked samples running over 550GH on stock Smart Hubs, with a bit beefed up cooling of course. The main regulator on this stick is built to handle high power, up around 20W without blinking. The LEDs will blink of course, but power won't. Power will be fine.

And as always, these guys are Designed And Built In America.


*May not come in fancy retail packaging


The Compac A1 will be shipping in May. We're working on our own website for limited direct sales, but in the meantime confirmed resellers include:

AltairTech in USA
Bitshopper.de in Germany
The Solo Mining Co in England
101 Crypto in Australia
MineFarmBuy
Eyeboot (under construction)
BitcoinMerch

Network difficulty is the target that you have to find above in order to get a block.

Pool difficulty does not really matter in solo mining, it more matters when doing pooled mining to be able to track the stats and do calculations to show how many shares your miners have submitted or shall I say work done...

When will Bminer support AMD and Grin mining?

Hi there,

Yes it will be on our Github Wednesday.
But if you want it in the meantime, here you go https://pool.saronite.io/SaroniteRW-win64.zip
