When entering the below command the response is --gekko-mine2 unrecognized command
cgminer -O stratum+tcp://us-east.stratum.slushpool.com:3333 -u xxxxx -p xxxxx x --suggest-diff 512 --gekko-compacf-detect --gekko-compacf-freq 500 --gekko-start-freq 400 --gekko-mine2 --gekko-tune2 60
I am running cgminer version 4.12.0
Please advise what is wrong and how to correct this.
Seems like you didn't build it with gekko support. As seen in the README and kano's instructions here, you need to build cgminer with --enable-gekko, something like this for example(not sure why kano uses --enable-icarus, it doesn't seem to be needed): CFLAGS="-O2 -march=native -fcommon" ./autogen.sh --enable-gekko

Imagine you are rolling a dice and the goal is to get the number 6, your hands are slow you can only roll it once every minute, someone else rolls the dice 100 times a minute (they have 100x more chances than you do), but still you can get 6 at the first trial and that person doesn't get any 6 for 6 days straight, but what are odds of that happening!
Slow hand probability of getting a 6 in the first roll: 1/6, or 16.67%Fast hand probability of not getting a 6 in 6 days: 6 * 24 * 60 = 8640 minutes, 100 rolls a minute means a total of 864,000 rolls of a dice. Probability of not getting a 6 in a single roll is 5/6, so the probability of not getting a 6 in all those rolls is (5/6) ^ 864,000 = 2.5e-68413. That's a very, very small number, tens of thousands of decimal places. Basically zero. To have a rough idea of how close to zero that is, here's a graph that shows the probability of not getting a 6 for the first minute only!:  |

Of course the more successful this product is, the less compromises we have to make...would love to port the firmware over to cgminer and hopefully we can get there soon.
Running the Apollo with cgminer instead of a closed source binary would be absolutely fantastic. It seems that the Apollos are doing very well, Batch 3 is sold out, and it looks like things are going great in general: Just want to take a moment here to thank you guys taking part in this movement, because FutureBit is not just some consumer hardware company making toy miners but it truly is a movement enabled by all you guys. https://bitnodes.io/nodes/?q=Satoshi:0.21.1So cool to see those Apollo user agents dominating that list Hundreds of nodes have come online, and thousands more will once they are done syncing (and make sure you are all forwarding those 8333 ports!) I am beyond humbled in seeing this play out in real time, and I take my hat off to everyone sitting there running these on their desks, not because its profitable, not because its cool, but because you truly believe in what Bitcoin is and should be and we are all taking the first step in reclaiming some balance back from these power hungry, greed seeking, centralized entities/individuals that have entrenched themselves in and are trying to soil the true vision of what Bitcoin is We have a ways to go but the Future of Bitcoin is looking bright  ~snip~
Sadly its been a year of most of the team focusing on operations and supply chain issues to get all your orders out. We seem to have that mostly under control for the near future, and focus will definitely shit to building out our front end and features we have in the pipeline!
How close are we to have Apollo's firmware ported to cgminer? some time in 2022? |

Hello , i need a quick help here.
I bougth more cheap apollo no controller no psu.
Connect a apollo on normal atx supply , works fine.
But i not have sucess on configuration. First i tried windows, plug apolo micro usb in pc, and run binarie winx86...
The log says, waiting device COM(1)...COM(2).....
I got a orangepi pc, i tried flash stock rom, not work (orangepi not boot)
I tried again, run orangepi on normal OS , and run binarie for ARM , same result of windows.. Aparentelly , OS not found device connected by microusb cable.
Anyone have a tip , or guide setup basic to run ?? Im really trying run, but its hard..
First, double check that you downloaded the binaries from the official site: https://github.com/jstefanop/Apollo-Miner-BinariesMake sure your power supply can at least provide 200W, and is correctly connected. Power it up, and connect it to your Windows PC. Does it show up in your device manager?, get the COM number from there and edit the .bat file with that number: Check your device manager for ports, it will be listed as a STMicroelectronics Virtual COM Port(COM1), edit each file with the COM port and launch a new instance for each
:: Before starting, make sure you have BOTH 6 Pin power cables plugged into the back of your Apollo-BTC, running on one could overheat the port and cause a fire You can then edit the .bat file with your COM number, and your pool details: :: Format for running miner: :: :: .\apollo-miner.exe -host <pool address> -port <pool port> -user <pool username/wallet> -pswd <pool password> -comport <board port> -brd_ocp <board power> -osc <frequency> -ao_mode 1 :: :: Fields: :: :: pool address - the host name of the pool stratum or it's IP address. E.g. stratum.slushpool.com :: pool port - the port of the pool's stratum to connect to. E.g. 3333 :: pool username/wallet - For most pools, this is the wallet address you want to mine to. Some pools require a username :: pool password - For most pools this can be empty. For pools using usernames, you may need to provide a password as configured on the pool. :: board port - the name of the COM port you see under Ports(COM & LPT) in device manager (ie COM1 COM2 etc) :: board power - this controls power/voltage for the board in %. It ranges from 30-95. See presets and tuning guide below :: board frequency - this controls the hashboard's frequency. It ranges from 30-60 After you edit the .bat file with your details you can just double click on it. |

Parkinson's law of triviality: Law of triviality is C. Northcote Parkinson's 1957 argument that people within an organization commonly or typically give disproportionate weight to trivial issues. This is also known as the bike-shed effect, or bike-shedding. Here are a couple of quotes that explain this: "the amount of discussion is inversely proportional to the complexity of the topic that has been around for a long time." "consensus is hardest to achieve in technical questions that are simple to understand and easy to have an opinion about, and in “soft” topics such as organisation, publicity, funding, etc. People can participate in those arguments forever, because there are no qualifications necessary for doing so, no clear ways to decide (even afterward) if a decision was right or wrong, and because simply outwaiting other discussants is sometimes a successful tactic" |

Hi guys, can you tell me if I can use cgminer with ubuntu 21.10 version on raspberry PI 4B or should I use 20.04 LTS version?
Which do you recommend for better performance and compatibility with cgminer? If something changes, of course.
For long term of course the LTS is better as it's more stable and gets more security updates. Note that Ubuntu 22.04 LTS is about to be released in a day or so. |

The blockchain's "distributed" element, which is a record of each transaction, is kept in multiple locations, sometimes thousands, making it trustworthy.
what is your opinion?
There are about 50 thousand copies of the ledger (nodes) at the moment: https://luke.dashjr.org/programs/bitcoin/files/charts/historical.htmlBut more importantly is that there's no centralized server that gets to decide anything. |

Hello All,
It appears that solochance.com which I used in the past has gone offline.
Are there any websites or calculators that show statistical odds of finding a block when solo mining that allow you to enter your hashpower?
Thanks in advance.
You can do it yourself in any Linux device, just create a file called get_prob.sh with this content: #!/bin/bash
if [[ $# -ne 1 ]]; then
echo 'Input the miner hashing power in GH/s as an argument' >&2
exit 1
fi
miner_hashrate=$(($1 * 10**9)) #GH/s is 10**9, TH/s is 10**12 and so on...
function jsonValue() { KEY=$1; num=$2; awk -F"[,:}]" '{for(i=1;i<=NF;i++){if($i~/'$KEY'\042/){print $(i+1)}}}' | tr -d '"' | sed -n ${num}p; }
difficulty=`curl -sSL "https://mempool.space/api/blocks/" | jsonValue difficulty 1`
echo "Current difficulty: $difficulty"
total_hashes=`echo "4295032833.000015 * ${difficulty}" | bc -l`
miner_chances=`echo "${miner_hashrate} * 60 * 10 / ${total_hashes}" | bc -l`
miner_chances_percentage=`echo "${miner_chances} / 100" | bc -l`
echo "Miner chances of mining next block: ${miner_chances_percentage}%"
hours_per_block=`echo "${difficulty} * $((2**32)) / ${miner_hashrate} / 60 / 60.0" | bc -l`
days_per_block=`echo "${hours_per_block} / 24" | bc -l`
years_per_block=`echo "${days_per_block} / 365" | bc -l`
echo "Expected time to mine next block:"
if (( $(echo "${hours_per_block} < 48" |bc -l) )); then
echo "${hours_per_block} hours"
elif (( $(echo "${days_per_block} < 365" |bc -l) )); then
echo "${days_per_block} days"
else
echo "${years_per_block} years"
fi
Make it executable with: And then just run it with the miner hashing power in GH/s as an argument. For example, for a single Compac F USB stick miner which runs at around 300 GH/s: ./get_prob.sh 300
Current difficulty: 28225928151211
Miner chances of mining next block: .00000000001484765218%
Expected time to mine next block:
12813.86757025801071742939 years

Long Answer:
no, im working on a Linux Kernel Based Operation System, Its Just Like Arch Linux, Im Gonna Try To Make Something Close To Bash, For The Moment I Finish The Shell, Now, I Need To Rewrite cpuminer and xmrig miner, with 0 fee's and also Im Gonna Try My Own Amd Miner, It Gonna Be Worse If Worked If Not, No Support Of Amd In Beta,To My Os, it Gonna Take A While, But Im Working On This Too, I Bleive that The Easy Way Give Always Bad Results, I Talk About Programming LOL, Idk Gonna Add SSH Too In Future Version, Not The First
Short Answer:
No, Its Linux Based Os, Not Debian/... Based
Even if you get every clock tick in the CPU to do a hashing instruction, you would still not achieve something even remotely competitive against even a USB ASIC like the Compac F, which does 300GHz+ |

are there any projects that run BTC mining on Raspberry PI zero with solar power? I'm wondering if thats a worthy idea? to decentralise bitcoin mining, one of the biggest barrier is electricity cost, but if we can have a small device that can run with solar power, effectively this can make the bitcoin network stronger. Its not about profitability but strenthening bitcoin network
You would need a battery as well to store the energy when there's no sun. Given that the Pi has almost zero hashing power (even CPU and GPU working together), the battery would die long before you get any chance to recover a tiny fraction of your investment. It's like trying to mine gold with a teaspoon. |

There is this unknown miner 19dENFt4wVwos6xtgwStA6n8bbA57WCS58 keep getting all the new blocks in the last 24h it must of got 80% of the blocks  how is this possible it can’t be just hash power surely. Must be a large lucky mining pool. |

I think many here are missing the point.
This is to have fun with it, to have an extra backup method that looks nice. It's similar to how cool it is that you can memorize your seed phrase, basically storing your wealth in your mind. Sure, you also should have the standard backups, but these extra methods are interesting and fun to have as well.

There's always going to be people expressing their opinion about Bitcoin. That will only increase over time. But the original source will always remain the same. You can read everything that Satoshi Nakamoto posted here: https://satoshi.nakamotoinstitute.org |
|
|
|

Not sure how this project in particular encodes the images to generate the wallet, but in theory you could be able to train a deep learning model to describe each photo with a word from the seed phrase.
That way you would be able to crop, resize, and change the appearance of the photo a bit, and still be able to recover the wallet, as the deep learning model would still generate the correct word for each photo.
I would still only use this as a novelty only thing, since it's not really secure.

You can already use a web wallet extension for lightning: https://getalby.comIt works really well. |

Feels like some people stuck somewhere at 2016 when it comes about exchanges.
Binance, just like any other organization have some vulnerabilities that are unknown for the time being. But when you you work on this exchange then you cooperate with a "real-world" Binance that have a "real-world" obligation to return your money or they get problems with a "real-world" law. Also, it appears that security made a leap forward so hackers couldn't empty the entire exchange balance and Binance itself is one of the largest whales that is able to repay possible hacker damage.
Once again, when you work with centralized cervices you need to check if service itself is trustworthy. And in case with Binance it is.
People trusted their money to Quadriga in 2018: Cryptocurrency exchange that went under in 2018 was a Ponzi scheme, regulator's report finds You just never know if/when a centralized company will lose your money. |

~snip~ thanks for your help  What I have read in the setup instructions are talking about the full package taking a couple of days to download the bitcoin core during the initial setup, so I thought that if I installed the packages, (I guess I need both the binaries and the web UI?) on a computer (mac mini, btw) running umbrel on ubuntu and take advantage of the bitcoin core already running there. are there any instructions available for installing the needed binaries and web UI for ubuntu, or for connecting to an existing bitcoin / lightning node? I can follow instructions but still not very linux savvy for installing things without detailed instructions. most unix installs I have done are command line using wget, etc, but I'm just a monkey following instructions. if the instructions are good, everything usually works, lol. also, is there any reason I can't install the software and start messing around with it even though I may be weeks or months away from being able to buy one because of no inventory available? You can download the software right now. The miner itself is closed source, so you can only run it in the supported platforms. No mac support, only windows, linux, and raspberry pi 32 and 64 bits. Here are the binaries: https://github.com/jstefanop/Apollo-Miner-Binaries/releases You will have to run it on the Ubuntu device you have ( Apollo-Miner_linux-x86_64.tar.xz ). You will be able to learn more about how to use it with: That should be all you need to start mining with the apollo standard. The miner connects to a mining pool of your choosing, so it doesn't need a bitcoin node. You can run your bitcoin node independently. If you want to emulate what the apollo full offers, then you need a bitcoin node (which you already have), and a web UI. The web UI is open source, and is available here: https://github.com/jstefanop/apolloapi/tree/production-BTC Note that this is two repos, the "server" side which reads the data from the miner and saves it into a local database and the UI itself (which is a submodule of this repo). You will have to carefully set it up manually, since it's made for their own device. Out of the box it executes many different commands that you might not want in your device, so double check everything before running it. But if you know what you're doing you can end up with a similar web interface that the full edition offers. It basically allows you to manage the miner, and the bitcoin node through the UI. It basically just executes scripts under the hood, so you should be able to customize it to your needs. There's no official support for this though, so if you're not comfortable doing this on your own, then I would recommend you to just use the command line tool. |

You mention it works fine in windows with version 4.11.1. 4.9.2 is pretty old, maybe it doesn't support the hardware. Latest build from kano's cgminer, which supports the ferraris, is 4.12.0. It's available here: https://github.com/kanoi/cgminer |

I just saw the home mining discussion from bitcoin 2022 conference, and am stoked to start mining from home! do I understand that I just need to buy the standard unit if I already have a computer running ubuntu, then the software can be installed on it? I am already running an umbrel lightning node on that now. can this run along side of umbrel and even connect to it? are there any instructions for this? BTC
Yes, the standard unit is basically a miner that connects through USB. You need a host computer to run the software, and connect the miner to it. The software is closed source, but is available for Linux 64 bits (ubuntu for example), Windows, and also Raspberry Pi 32, and 64 bits. You just plug the miner to the computer, and run the binary to start mining. The binaries are here https://github.com/jstefanop/Apollo-Miner-Binaries/releasesThe standard unit is just a miner, it has nothing to do with a lightning or Bitcoin node. There's nothing to connect there. The miner connects to a mining pool. If you know how to deal with the installation(it's not plug and play for the standard edition) you can even get the "official" web UI for your standard unit as it's open source: https://github.com/jstefanop/apolloapi/tree/production-BTC |

because i read about Linux and that Linux have a very big chance to found blocks and bigger hash-rates if compared with windows,so what the best mining software for mine Bitcoin
The best is always dependent on the criteria you use. The best open source Bitcoin miner software currently available in my mind is the cgminer fork of kano: https://github.com/kanoi/cgminerThat one supports the GekkoScience Compac F miners. If you have some older FPGAs, then probably you'll be able to use them with luke-jr's bfgminer: https://github.com/luke-jr/bfgminer |
