| | This article covers some specific aspects of the Bitcoin protocol. |
|

|
| My Bitcoin Address is: 1HDp1gU3rgrRNKqrKorz8uWCpHUNdyGqXm | | My Bitcoin Address is: 1HDp1gU3rgrRNKqrKorz8uWCpHUNdyGqXm |
|
| |
|
| | == Overview == |
| | Bitcoin is a decentralized protocol that operates in an untrusted peer to peer environment while still being a reliable method to exchange credits (bitcoins) between people. |
|
| |
|
| == BFGMiner ==
| | For detailed information, read the Bitcoin paper or one of the many sites out there. |
| | |
| Do the same as CGMiner below.
| |
| | |
| I compiled it using:
| |
| CFLAGS="-O2 -Wall -march=native -I/export/package_build/misc/miner/2.6/SDK/include" LDFLAGS="-L/export/package_build/misc/miner/2.6/SDK/lib/x86_64" ./configure --prefix=/usr/local/miner --enable-scrypt --enable-opencl
| |
| | |
| You also need to install jansson-devel and uthash packages.
| |
| | |
| | |
| For the 6870, this is what I did: | |
| <syntaxhighlight lang="bash">
| |
| #!/bin/bash
| |
| ./bfgminer -T -D \
| |
| --scrypt \
| |
| -o stratum+tcp://136.159.7.241:9327 \
| |
| -u pickaxe \
| |
| -p password \
| |
| -S opencl:auto \
| |
| --shaders 1120 \
| |
| --intensity 9 \
| |
| --worksize 128 \
| |
| --vectors 4 \
| |
| --gpu-threads 1 \
| |
| --gpu-engine 950
| |
| | |
| </syntaxhighlight>
| |
| | |
| == CGMiner ==
| |
| | |
| === AMD Cards ===
| |
| Download the AMD SDK and ADL SDK from:
| |
| * http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/
| |
| * http://developer.amd.com/tools-and-sdks/graphics-development/display-library-adl-sdk/
| |
| | |
| For older cards or drivers, use the older SDK (such as 2.6). You will know that you need to downgrade when things don't work. For instance, if you get:
| |
| * Segmentation Faults
| |
| * High "HW:##" values (hardware faults) from cgminer
| |
| * Not actually mining anything or other unexpected behavior.
| |
| | |
| Extract the archives and copy:
| |
| * AMD-APP-SDK/include -> /build_dir/include
| |
| * AMD-APP-SDK/lib/x86_64 -> /build_dir/lib
| |
| * ADL-SDK/include/*.h -> /build_dir/cgminer-3.3.4/ADL_SDK/
| |
| | |
| In the cgminer-3.3.4 source directory, run:
| |
| | |
| <syntaxhighlight lang="text" line start="1" enclose="div">
| |
| CFLAGS="-O2 -Wall -march=native -I/build_dir/include" LDFLAGS="-L/build_dir/lib" ./configure --prefix=/usr/local/miner --enable-scrypt
| |
| make
| |
| make install
| |
| </syntaxhighlight>
| |
| | |
| Extract icd-registration.tgz and put the files in /etc/OpenCL/vendors/.
| |
| | |
| Since I do not want to install the OpenCL libs, I had to copy them (from AMD-APP-SDK/lib/x86_64) over to /usr/local/miner/libs manually, and run cgminer with the LD_LIBRARY_PATH variable defined:
| |
| | |
| LD_LIBRARY_PATH=/usr/local/miner/lib ./cgminer -n
| |
| | |
| LD_LIBRARY_PATH=/usr/local/miner/lib ./cgminer -o http://p2pool.org:9332 -u 1HDp1gU3rgrRNKqrKorz8uWCpHUNdyGqXm -p password
| |
| | |
| | |
| === NVidia Cards ===
| |
| | |
| You will need to install the NVidia drivers and the cuda toolkit.
| |
| | |
| Once done, compile cgminer with the following paths:
| |
| | |
| <syntaxhighlight lang="bash" line start="1" enclose="div">
| |
| CFLAGS="-O2 -Wall -march=native -I/usr/local/cuda/include" LDFLAGS="-L/usr/lib64/nvidia" ./configure --prefix=/usr/local/miner --enable-scrypt
| |
| </syntaxhighlight>
| |
| | |
| Note that there is no 'ADL' for Nvidia as that's specific to AMD.
| |
| | |
| == P2Pool ==
| |
| === Get the source ===
| |
| git clone git://github.com/forrestv/p2pool.git
| |
| | |
| === Install Dependencies ===
| |
| Either install the packages from <code>yum</code> or from source. The dependencies that are needed are:
| |
| # Twisted
| |
| ## zope
| |
| # Argparse
| |
| | |
| From yum, run:
| |
| yum install python-argparse python-twisted python-twisted-web
| |
| | |
| Since the Twisted library is somewhat old, you might want to build it from source by getting it from:
| |
| # https://pypi.python.org/pypi/Twisted#downloads
| |
| And also the dependency:
| |
| # https://pypi.python.org/pypi/zope.interface/4.0.5#downloads
| |
| | |
| Extract the archives, and run the setup.py script to build. (You will need python-devel and gcc to build)
| |
| | |
| | |
| === Running P2Pool ===
| |
| Run run_p2pool.py
| |
| | |

| #### I am not responsible for you using these instructions.

| |
| #############################################################
| |
| ####
| |
| #### While at your windows desktop machine you need to
| |
| #### download the ISO from http://vault.centos.org/6.0/isos/
| |
| ####
| |
| #### (I will be using the 64 bit OS from here on out)
| |
| ####
| |
| #### The ISO can be burned to CD, DVD or USB
| |
| ####
| |
| #### (I will burn the ISO to a 2GB+ USB flash drive)
| |
| ####
| |
| #### Download the ISO from:
| |
| #### http://vault.centos.org/6.0/isos/x86_64/CentOS-6.0-x86_64-LiveCD.iso
| |
| ####
| |
| #### Download and install Pendrivelinux Windows Software:
| |
| #### http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/
| |
| ####
| |
| #### 0. Plug in your flash drive and wait for it to register
| |
| ####
| |
| #### 1. start pendrivelinux universal USB installer
| |
| #### 2. selects CentOS from "other distros alphabetically"
| |
| #### 3. select the CentOS LIVE iso you downloaded
| |
| #### (CentOS-6.0-x86_64-LiveCD.iso)
| |
| #### 4. select your drive letter and format the drive
| |
| #### 5. safely remove flash drive and plug into new machine
| |
| #### 6. boot up and install CentOS with the menus
| |
| #### 7. after intallation log in as root (or su) and:
| |
| #### 7a. set up network so IP is fixed so you can log in remotely
| |
| #### 7b. turn on the SSH daemon so you can log in (service sshd start)
| |
| #### 7c. make sshd starts each time you boot (chkconfig sshd on)
| |
| #### 8. now I like to go back to my nice desk and chair
| |
| #### 8a. dowload and install putty so you can talk to your box
| |
| #### http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
| |
| #### using a new ssh connection, connect to your machine as the
| |
| #### user you set up during installation. (it's a bad idea to log
| |
| #### in as root from a remote location).
| |
| #### 9. while you are sitting there at your desk download and install
| |
| #### xming windows xwindow emulator from here:
| |
| #### http://sourceforge.net/project/downloading.php?group_id=156984&filename=Xming-6-9-0-31-setup.exe
| |
| #### 10. modify yum

| |
| ####[Message] Kernel Module : Precompiled kernel module version mismatched.
| |
| ####[Error] Kernel Module : Kernel module build environment not found - please consult readme.
| |
| ####
| |
| ####
| |
| #### This error indicated you do not have the correct kernel-devel libs to match your kernel
| |
| #### (I told you it wouldn't work).
| |
| ####
| |
| #### with xming installed on my pc when I use putty I don't even need to
| |
| #### export my display. I can just start playing with opencl and opengl
| |
| #### libraries and samples. But only if I did everything correctly
| |
| #### and there were no hardware issues along the way.
| |
| ####
| |
| #### my machines 'hello world' test passed with flying colors
| |
| ####
| |
| aticonfig --lsa

| ## output looks like this:
| |
| #* 0. 0e:00.0 AMD Radeon HD 6800 Series
| |
| # 1. 0f:00.0 AMD Radeon HD 6800 Series
| |
| # 2. 07:00.0 AMD Radeon HD 6800 Series
| |
| # 3. 06:00.0 AMD Radeon HD 6800 Series

| |
| #* - Default adapter
| |

| |
| # which is EXACTLY what I want!!!
| |
| | |
| #### if you are not seeing all your GPU's at this stage something is wrong.
| |
| #### first check lspci
| |
| lspci -nn | grep VGA
| |
| | |
| #### if that does not show all your cards you need to hard-boot your computer.
| |
| #### it make take several attempts and some plugging and unpluggging monitor
| |
| #### cables. There seems to be little method to the madness but make sure
| |
| #### you can see all your GPU's now or you can't mine with them. Even though
| |
| #### centos was designed to handle multiple GPU's off the bat I still find the
| |
| #### best way to 'light up' a port is to have a monitor plugged in during hard
| |
| #### boot. I'm sure the resistor based dongle approach would work as well.

| ## uh-oh I broke something!
| |
| ## oh yea, I remember
| |
| ##
| |
| ## I forgot to log into the linux box.
| |
| ## so here's what I need to make this work
| |
| ## I go to the centos box and log in as my
| |
| ## regular user in the graphical interface.
| |
| ## then I pull down the menu and open a
| |
| ## terminal window which must be 'turning
| |
| ## x on for my local user'. Once I open
| |
| ## that terminal (xterm) I can walk away
| |

| |

| ####
| |
| #### Now test out your new miner for 24 hours and if you like all the time and effort I
| |
| #### put into this guide I encourage you to think about testing your new miner here:
| |
| | |
| ./cgminer -o stratum+tcp://mining.eligius.st:3334 -u 1NQc6tCtRmT8zBeLKNpboFaUBMLcxDwUm6 -p x0 -I 9 --per-device-stats 2>logfile.txt
| |
| | |
| ####
| |
| #### After 24hrs of burn in read the logfile. Make sure nothing strange happened.
| |
| #### Here's how you read the log:
| |
| | |
| more logfile.txt
| |
| | |
| #### If you don't see any errors set your miner to your favorite pool and off you go.
| |
| #### Then set that file aside so you can refer to it later.
| |
| | |
| cp logfile.txt burninlog.txt
| |
| | |
| #### in the future, unless you are having problems you can remove the --per-device-stats and the logging
| |
| #### from the command line, so it looks like this: (don't forget to change the address!!)
| |
| | |
| ./cgminer -o stratum+tcp://mining.eligius.st:3334 -u 1NQc6tCtRmT8zBeLKNpboFaUBMLcxDwUm6 -p x0 -I 9 | |

| | == Address / Keys == |
| #### The End
| | An address consists of a public / private key pair. |
| #############################################################

| </syntaxhighlight>
| | === Brain Wallets === |
| | A brain wallet allows for the generation of the public/private key pair using a passphrase. It is accomplished by: |
| | # Converting a pass phrase into a private key |
| | #* PrivateKey = SHA256(PassPhrase) |
| | # Generate a public key using the private key |
| | #* PublicKey = privateToPublic(PrivateKey) |
| | # Generate the bitcoin address |
| | #* Hash = SHA256(PublicKey) |
| | #* Hash160 = RIPEMD160(Hash) (used by transactions) |
| | #* Address = Base58Check(Hash160) |
|
| |
|
| | The publickey can either be uncompressed or compressed. A compressed public key is simply a truncated key where the missing parts can be recomputed. |
