Mining Setup

To mine Bitcoin Rhodium you need to set up an XRC wallet and configure your miner of choice. You can choose between Web wallet, Electrum-XRC or Magnum wallet. To set up a web wallet please visit wallet.bitcoinrh.org. Or download and install Electrum-XRC wallet (recommended) for Windows, Linux and MacOS.
Web wallet: wallet.bitcoinrh.org
Electrum-XRC wallet: electrum.bitcoinrh.org
Magnum wallet: https://magnumwallet.co

Sign up for XRC web wallet if not yet done so

  1. Create an account, with your username, password and secure question.
  2. Sign in and click “Create Wallet”.
  3. Set up a strong transaction password. Make sure you store it securely in a secure password manager of choice.
  4. Copy the seed somewhere safe. It’d be a good idea to write seed on a hardcopy and keep it safe.
  5. Paste it to confirm you got it right.
  6. Grab an address for the mining step. Your wallet is now ready to mine XRC.

Instructions for mining XRC on the official pool

Pool link: poolcore.bitcoinrh.org
  1. Any miner that supports X13 will be able to mine XRC. We have a few examples below of miners that are well tested with Bitcoin Rhodium network.
  2. For any miner, configure the miner to point to:
(0–0.8 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3061
(0.8–2 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3062
(3–4 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3063
(5+ GH/s) stratum+tcp://poolcore.bitcoinrh.org:3064
with your XRC address as username and x as password. You don’t need to open an account on pool. You will be mining to XRC address and mined coins will be transferred to your wallet
after blocks reach 10 block maturity
after you mined up minimal amount of coins (currently 0.1 XRC)
sometimes mined blocks could get rejected by network (orphaned) after they were counted as valid blocks. This is normal network behavior to follow longest chain
  1. http://poolcore.bitcoinrh.org is used to follow your miner and network statistics.

CPU Miner-Multi

Source: https://github.com/tpruvot/cpuminer-multi
Sample configuration with CPU Miner tested on UBUNTU.
“url” : “stratum+tcp://poolcore.bitcoinrh.org:3061”, “user” : “YOUR XRC ADDRESS”,
“pass” : “x”,
“algo” : “x13”, “threads” : 1,
“cpu-priority” : 5,
“cpu-affinity” : 1, “benchmark” : false, “debug” : true, “protocol”: true, “show-diff”: true, “quiet” : false
Command to run your CPUMiner: cpuminer -c cpuminer.json


SGMiner is a GPU-based mine: https://github.com/nicehash/sgminereleases
The configuration below was tested on Windows:
cd C:\Software\sgminer-5.6.1-nicehash-51-windowsamd64 sgminer.exe
— gpu-platform 1 — algorithm x13mod -url stratum+tcp://poolcore.bitcoinrh. org:3062 — pool-user — userpass :x — auto-fan — temp-target 70 — temp-over- heat 82 — temp-cutoff 85 — gpu-fan 65–85 — log-file log.txt — no-adl — no-extra- nonce -P –T


CCMiner is a GPU-based miner (NVIDIA)
Command to run your CCMINER:
ccminer-x64.exe -a x13 -o stratum+tcp://poolcore.bitcoinrh.org:3062 -O :without -D — show-diff

Baikal miner

Settings: Url:
(0–2 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3062
(3–4 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3063
(5+ GH/s) stratum+tcp://poolcore.bitcoinrh.org:3064
Algo: x13User: your XRC receiving address (make sure you set 2 distinct addresses for each hashing board)
Pass: x
Extranonce: leave off Priority set to 0 and 1
Once pool stratum address and your wallet as user are set up you should see your miner mining against XRC pool. When miner is working the status column is green. The pool and miner are incorrectly configured now as status says “Dead” highlighted in red.

Instructions for mining XRC on BSOD pool

Pool link: bsod.pw/en/pool/dashboard/XRC/
Use this code for your miner: -a x13 -o stratum+tcp://pool.bsod.pw:2582 -u WALLET.rig
BSOD pool allows both solo and party mining.
For solo mining use code: -a x13 -o stratum+tcp://pool.bsod.pw:2582 -u WALLET.rig -p m=solo And for party mining use: -a x13 -o stratum+tcp://pool.bsod.pw:2582 -u WALLET.rig -p m=party.yourpassword
NOTICE: You can use us for North America and asia for Asia instead of euin your .bat file or config.
You can also use BSOD pool’s monitor app for Android and iOS.

Instructions for mining XRC on ZERGPOOL

Zergpool offers low fees (just 0.5%) and also SOLO and PARTY mining with no extra fees.
To mine XRC on Zergpool use this command lines for your miner:
Regular: -a x13 -o stratum+tcp://x13.mine.zergpool.com:3633 -u -p c=XRC,mc=XRC Solo: -a x13 -o stratum+tcp://x13.mine.zergpool.com:3633 -u -p c=XRC,mc=XRC,m=solo Party: -a x13 -o stratum+tcp://x13.mine.zergpool.com:3633 -u -p c=XRC,mc=XRC,m=party
Use your coin wallet address as username in mining software. Specify c=SYMBOL as password to identify payout wallet coin, and the same coin in mc=SYMBOL to specify mining coin.
For more information and support please visit http://zergpool.com
Notice that when there are more pools mining XRC in different geographic/availability locations choose the nearest to you as lowest priority and then add desirable fall back pool options in different geographic locations or pools. This is useful when one pool experiences issues, to fall back to different pool in Bitcoin Rhodium network.

NOTE: if server is 1GB RAM, before running last command "sudo make", set up a swap file
free #check if swap is 0 dd if=/dev/zero of=/vaswap.img bs=1024k count=1000 mkswap /vaswap.img swapon /vaswap.img free #check if swap is 1024 sudo make 

cd src ./biblepayd -daemon 
Your GUI program will be located in: /biblepay-evolution/src/qt
You can also run it in the background (to free up your terminal) if you call it with:
./biblepay-qt & 
To start mining, instructions are the same as for Windows: Go to Tools -> Debug Console
Execute this command (to start mining with 8 threads)
setgenerate true 8 
From there you can use all other commands such as getmininginfo, getwalletinfo, etc. Execute help command to get the list of all available commands.
Note: GUI will be built automatically only if you meet the requirements for qt library, i.e. make sure you ran this line before compiling:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler 
BIBLEPAY is now Running!

Stop BiblePay and set up the config file to get starting nodes to sync with and enable mining:
./biblepay-cli stop cd ~/.biblepayevolution/ vi biblepay.conf addnode=node.biblepay.org gen=1 genproclimit=1 
Escape Key + : (Colon Key) + w + q + Enter (saves file and quits)

addnode --- adds a node to the list of nodes to connect to gen=1 --- turns on mining genproclimit --- sets number of threads to use when mining

Run BiblePay again and fully sync with network

4. Restart BiblePay
./biblepay-cli stop ./biblepayd -daemon 
Setup Auto-Withdraw Navigate to Account >>> Account Settings >>> Verify your BBP Receiving Address >>> Click Authorize-Auto-Withdraws


### Turn off/stop BiblePay
cd /home/yourname/biblepay-evolution/src ./biblepay-cli stop 

### Pull down latest Biblepay code and build it
cd /home/yourname/biblepay-evolution git pull origin master sudo make 

### Turn BiblePay back on and check version number
cd src ./biblepayd -daemon ./biblepay-cli getinfo ./biblepay-cli setgenerate true 8 

./biblepay-evolution/src/biblepay-cli stop ; cd && cd biblepay-evolution/ && git pull origin master && sudo make && cd src && ./biblepayd -daemon && sleep 90 && ./biblepay-cli getmininginfo 
Note: the ";" says do this after, regardless of the outcome Note: && says do this after only if previous command finished with no errors

To speed up the compile time, add -j4 or -j8 after make. This way it compiles using 4 or 8 threads instead of just 1.
./configure LDFLAGS="-L${BDB_PREFIX}/lib/" CPPFLAGS="-I${BDB_PREFIX}/include/" sudo make -j8

Zeus/Gaw ASIC Setup Guide for Linux/Raspberry Pi

So I recently I became quite interested in mining and cyptocurrencies in general. So interested in fact that I bit the bullet and decided to buy myself a GAW Fury.
I then spent some time doing research on how to set up a GAW or Zeus ASIC on Linux, in particular on a Raspberry Pi, and have found most guides to be awful. The reason they are so bad IMHO is that they assume quite a bit of prior knowledge, either with Linux or mining, and give very little instructions. So I have tried to put together a guide that requires very little prior knowledge.
It is my aim that anyone could get their shiny new asic up and mining in no time using this guide. Anyway, I present...

The Complete Noobs Guide to Setting Up a Zeus or Gaw ASIC on Debian/Ubuntu/Raspberry Pi


About Cyrptocurrencies and Their Jargon

If you are new to cryptocurrencies and how they work I suggest taking a look at this series of KhanAcademy videos. They are for Bitcoin but the theory is the same. I found them very helpful when it came to understanding what mining actually does and the mechanics of cyrptocurrencies.
Also take a look at sircamm22 his info found here, is great and breaks down a large number of concepts. I slightly disagree with no. 21 regarding preordering. Just exercise common sense.


If you are new to Linux you could follow along by simply typing in the commands. However I highly recommend taking the time to learn what you are doing. This course is a great place to start.

Computer Setup

By the end of this section you will have your device turned on, fully setup and connected to the internet with.
Note: Commands to be typed into the command line will be displayed like this:
echo Hello World


For laptops and desktops already running Ubuntu or Debian I will assume you have setup your internet setup as part of the installation.
If not: There are plenty of guides out there and the installation/setup process is very easy. A good place to start for Ubuntu is here.
Now open up a terminal window. Ctrl + alt + t on a standard Ubuntu installation.
If you plan on using this PC without a monitor I would suggest installing an SSH Server.
These commands will be discussed later on in the guide.
sudo apt-get -y install openssh-server
sudo service openssh-server start

Raspberry Pi

The Raspberry Pi Foundation has put together a great guide in PDF format.
Use NOOBS it will save you a lot of trouble. NB: Some SD cards don't support NOOBs but will work fine if the image is put on using a different method.
Here is a great guide for setting up the Raspberry Pi SD card from Elinux.org. In fact it's a great place to start for anything RPi related. Raspberry Pi hub at Elinux.
Once the SD card is setup you will need to insert it into the Raspberry Pi and boot. Install Raspbian from the NOOBs menu and wait.
Follow this guide by Adafruit for first time setup. You will need to enable SSH Server.
I suggest not starting the desktop on boot. It can be easily run from the command line by typing startx.
Follow this guide by Adafruit to setup your network. Found here. No need to do this if you set up previously in the first time config.
We will also at this point want to setup ssh. Again I will point you to an Adafruit guide.
Once done exit back to a standard command line interface. This can be done in LXDE by using the power off menu located in the bottom right corner.

Miner Setup

Installing BFGMiner

If you want to the Raspberry Pi or PC without a monitor go ahead and SSH into your device.
So now you should be staring at a command line interface whether on the device with a monitor or via SSH.
First things first lets make sure we are all up to date. This will update our package list from the repositories and upgrade them to the newest version. "-y" Will simply say yes to any prompts.
sudo apt-get update && sudo apt-get -y upgrade
We are going to need to install some useful tools. Git-core is how we will clone and download BFGMiner from GitHub and Screen allows multiple command line instances and means if we exit out of ssh session or quit Terminal on Ubuntu, BFGMiner will continue to run.
sudo apt-get install git-core screen
We also need to download some other tools/dependencies to ensure that BFGMiner will compile successfully.
sudo apt-get -y install build-essential autoconf automake libtool pkg-config libcurl4-gnutls-dev libjansson-dev uthash-dev libncursesw5-dev libudev-dev libusb-1.0-0-dev libevent-dev libmicrohttpd-dev libc-bin
Ok now change into your home directory.
cd ~
And clone BFGMiner by Darkwinde.
git clone https://github.com/Darkwinde/bfgminer.git
Once the download has completed move into the bfgminer directory.
cd bfgminer
The following steps may take a while.
Now run autogen.sh
sudo ./autogen.sh
You will need to make the configure script execuitable.
sudo chmod +x ./configure
Now configure bfgminer
sudo ./configure CFLAGS="-O3" --enable-scrypt
Now lets make!
sudo make
Install BFGMiner
sudo make install
One more thing...
sudo ldconfig

Running BFGMiner

If you haven't already plug in your ASIC.
Just confirm your system is recognising the ASIC.
Its output should look similar to this (no need to type this in):
Bus 001 Device 005: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Yep there it is our ASIC listed as device 005. There is no need to install any drivers, unlike in windows, as they come in the kernel.
Now lets actually start BFGMiner.
You will want to start a screen session to ensure BFGMiner doesn't quite when you exit.
"-S" is the option for starting a new screen session. You can replace "miner" with anything you like.
screen -S miner
Now you can run the commands below.
Here is a sample of what you should type. You will need to replace somethings with your own values.
sudo bfgminer --scrypt -o stratum+tcp://URL:PORT -u USERNAME -p PASSWORD --zeus-cc CHIPCOUNT --zeus-clk 328 -S zeus:/dev/ttyUSB0
URL:PORT is the address and port of the pool you wih to use. Now I won't suggest a pool. I will leave that decision up to you. If you do wish to mine DOGE take a look at this site for a list of pools and comparisons.
USERNAME this is the username you use on the pool. Every pool is different. Check your pool's website for details. PASSWORD same as above. Specific to your pool, not every pool requires one.
CHIPCOUNT this is specific to which ASIC you are using.
For GAWMiner ASIC's:
  • War Machine: 256
  • Falcon: 128
  • Black Widow: 64
  • Fury: 6
For ZeusMiner ASIC's:
  • Blizzard: 6
  • Cyclone: 96
  • Hurricane X2: 48
  • Hurricane X3: 64
  • Thunder X2: 96
  • Thunder X3: 128
Now to make sure you don't stop mining when you exit ssh or terminal. Press:
ctrl + a + d
To come back to the BFGMiner screen simply run:
screen -r miner
You're done!!

Start on Boot

First off you will want to make sure you have BFGMiner running correctly. Ensure you have the miners set up properly and your pool correctly configured.
Start a BFGMiner instance, detailed above.
Once the instance has started and you are happy with how everything is working press "s" on your keyboard to enter the settings menu.
Now press the "w" key. Don't press enter. We want to specify where our config will go. Type:
Substitute USERNAME for your user. On a standard RPI install its pi. On ubuntu it's what you set during the instillation.
Now press the enter key to return back to the main BFGMiner screen. Press "q" on your keyboard to exit BFGMiner. You should now be back in the command line.
Now we want to edit a file called rc.local. Any commands in this file will be executed on boot.
sudo nano /etc/rc.local
Depending on your system this file may already contain some commands. Be careful not to delete them.
After the last command and before "exit 0" type the following on one line:
sudo -u USERNAME screen -d -m sudo bfgminer --config /home/USERNAME/bfgminer.conf
Where USERNAME = your username
Hit ctrl + x then y to save and exit nano.
The above command will create a new screen session and run bfgminer using the config we created earlier. All while as our username so that we can easily reattach.
Lets reboot to ensure it is working correctly:
sudo reboot
Once rebooted and logged in, show all running screen sessions:
screen -ls
Reattach to the session. You only need to use the numbers before the first dot.
e.g Mine looks like: 2480..hostname (13/07/14 12:02:09) (Detached). So I type:
screen -r 2480
Verify everything worked as expected. Then ctrl + a + d to exit.
You have now setup BFGMiner to restart on reboot.

Power Failure

If you are using a Raspberry Pi and it loses power it will automatically reboot on receiving power again.
For standard desktop PCs there is an option in some BIOS/UEFI to turn the computer on when it receives power. Consult your motherboard's manual and manufacturer's website.


Here is where I got my info from.
And of course /dogemining

Wrap Up

Congrats you've done it. You have managed to successfully get your shiny new asic mining away.
I do plan to make another guide detailing how to setup and use StarMiner a ready to go RPi mining distro.
So I hope this is helpful for you guys. I have seen lots of posts asking the exact same questions again and again and I have tried to answer these as best I can. I am still learning about this stuff so if there is something I have missed or a mistake I have made please tell me.
Anyway good luck. And I'll see you at the moon.
Cheers Frogsiedoodle
Edit 1: Layout and formatting.
Edit 2: Added instructions for screen which I initially forgot.
Edit 3: Removed 1 unneeded dependency
Edit 4: Added section on start on reboot and power failure.
