五分钟，开启比特币挖矿之旅！ - 知乎首发于云体验师切换模式写文章登录/注册五分钟，开启比特币挖矿之旅！奉孝翼德对未知世界留有敬畏之心挖矿其实很简单，只需要：一台有计算能力的联网设备和一个小小的挖矿软件。设备可以是：一台笔记本电脑，一块装着FPGA的主板都可以。挖矿软件，以最有影响力的比特币来说，常见的有以下几个：CGMiner：CGMiner支持命令行方式，因为是C语言写的，所以效率比较好，跨平台也非常好。虽说是跨平台的，但是在我的Windows10上安装失败了，系统提示有毒，可能是因为别人修改了什么被病毒库发现了吧，还是推荐在Linux上运行CGMiner，为了简便起见，这次体验就选一个难度其实奇低的吧。Bitminter：Java写的跨平台的工具，有图形化界面，但是限定了只能用特定的矿池。此外还有BFGMiner，这个不支持GPU，无法发挥我GTX1070的威力，也放弃了。EasyMiner，有图形化界面，但是太丑了，而且，也会惹到防病毒软件，想想也是放弃了，唯一推荐的是这个叫NiceHash的软件，界面美观，适合有美学修养的爱好者体验。官网（https://www.nicehash.com/）软件实际截图很好看吧不仅美观，它支持CPU,ASIC当然还有GPU，而且是AMD和NVIDIA的GPU都支持，软件操作感觉也很不错。软件选好了，我来介绍一下我的电脑配置吧，2016年买的i76700K CPU+16GB RAM+GTX 1070显卡，还过得去。软硬件都有了，现在开始挖矿吧？等等……这时候要准备一个钱包，比特币钱包提供一串地址，唯一的地址，就靠这个地址记录你的比特币，丢了就真的丢了。然后，你需要选择一个矿池。当然，你也可以选择Solo挖，就是不做矿池公认，自己干，但是自己需要解决很多问题，比如安全问题，风险比较大，建议还是找个包工头（Pool）一起挖，旱涝保收，也不怕故障丢成果，也不怕黑客给你添乱，这些麻烦事儿都交给池主吧。当然，你得交保护费。我们先注册登录，登录后的Dashboard如下图。点击Wallet钱包选项，里面就有一串地址，如下图所示，一串以3或者1开头的字符串：Yourbtc address。你可以把这串地址复制出来，粘贴到软件里，也可以注册第三方的Wallet（钱包来用）。UseBTC Address，我用的是后者。我是在Coinbase上注册的，不考虑别的原因，纯粹为了测试起见，选择了Coinbase（Coinbase不支持中国地区用户买，限制中国用户交易）。选择自己找的钱包或者直接用NiceHash提供的钱包选矿池。NiceHash提供了矿池，挖矿的时候你可以直接用。另外，作为买家的话，你可以自己添加矿池。Stratum列表中有很多可选项如果你就是挖矿的话，用NiceHash的你可以暂时跳过选池子的问题，NiceHash自带池子。你也可以看看配置栏里的东西，有点迫不及待的朋友可以之间点击Start了，点了之后，马上就可以进入正式的Benchmark过程了。为了测试一下你机器的水平吧，过程中会相应的做一些优化。Benchmark如果能顺利走完，就可以开始挖矿了。挖矿对计算能力要求还是很高的，如果机器不太行的话，这次挖矿之旅可能就到此为止了。挖矿ing图中预估了一天挖矿的产出，这个是波动的数字，因为BTC也在波动，计算力也在波动。当你的BTC足够支付手续费的时候，你就可以考虑出售了。NiceHash更牛的地方是，这里就支持交易。更多内容自己挖掘吧，考虑到现在的行情，我还是让我的显卡歇一歇吧。https://miner.nicehash.com/祝大家挖的愉快，不用交电费发布于 2018-09-06 08:59比特币 (Bitcoin)挖矿挖矿机赞同 226 条评论分享喜欢收藏申请转载文章被以下专栏收录云体验师科技爱好者，IT科技八卦党（公号：云体

This is a multi-threaded multi-pool FPGA and ASIC miner for Dogecoin, bitcoin, Litecoin etc.
This code is provided entirely free of charge by the programmer in his spare
time so donations would be greatly appreciated. Please consider donating to the
address below. Driver development for new ASIC only Bitcoin hardware can be
suitably sponsored.
Do NOT download the latest version of cgminer (3.10+). The latest versions removed support for graphic cards and are only for ASIC hardware. The latest version you can get for Dogecoin mining is 3.7.2.
How To Use CGMiner
A simple step by step guide demonstrating how to mine scrypt cryptocurrency (i.e. Dogecoin, Litecoin etc.) using your AMD ATI GPU!
1
Download the miner
Download CGMiner by clicking the Download button.
To run mining on multiple computers, download and install the CGMiner application on all computers that will be used for mining.
Unzip downloaded package and open the .bat file in the text editor
In the folder that contains the miner, you should create or edit a file with .bat extension. You can do this in any text editor (for example, Notepad or Notepad++). When you save the file, it’s important to choose ‘All Files’ as a file type, not ‘txt’. Otherwise, you’ll have .bat.txt at the end of the file name, and miner won’t be able to open this file. Your bat file (let’s say it’s called Dogecoin-binance_pool.bat) should contain the following text (Step 2):
Attention! For security reasons, Windows may stop you from opening the bat file. In this case, you should permit it to open in the pop-up window.
2
Enter the following command:
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
cgminer --scrypt -o stratum+tcp://dogeminingpool.com:3009 -u DKs5E8nWJe2E5vYnVSoYqNjw2T17nGYUDo.1 -p password
3
Configure the miner with your settings
WALLET_ADDRESS - enter YOUR Ethereum wallet address or pool USERNAME (this is how CGMiner knows where to deposit your ETH)
RIG_NAME – you can choose any name (like test), but don’t exaggerate: it should be 32 symbols max, contain only letters and numbers (no special characters like $%»*;@). Do not forget to specify your wallet address in all files!
4
Start mining
Double click your Bat file to start the miner. The miner will start, run the setx commands to set those environment variables, initialize each of your GPU’s, build the DAG file on each of your GPU’s and start hashing away.
If you’ve followed the steps above you should see this screen.
How to find my crypto address?
Log into your Huobi account, in the Assets tab choose "Spot" and click on it.
On the opened page, click the "Select Coin" button. Select a network and get Dogecoin address.
Click on the "Copy address" button.
You can also use any other exchange or buy a cold wallet: Ledger or Trezor.

FAQ
What is an ASIC?
They are Application Specify Integrated Circuit devices and provide the highest performance per unit power due to being dedicated to only one purpose. They are the only meaningful way to mine bitcoin today.
Help, I've started cgminer and everything reads zero!?
Welcome to bitcoin mining. Your computer by itself cannot mine bitcoin no matter how powerful it is. You have to purchase dedicated mining hardware called ASICs to plug into your computer. See Q regarding ASICs below.
I have multiple USB stick devices but I can't get them all to work at once?
Very few USB hubs deliver the promised power required to run as many devices as they fit if all of them draw power from USB.
I've plugged my devices into my USB hub but nothing shows up?
RPis and Windows have incomplete or non-standard USB3 support so they may never work. It may be possible to get a USB3 hub to work by plugging it into a USB2 hub. When choosing a hub, USB2 hubs are preferable whenever possible due to better support all round.
Can I mine on servers from different networks (eg xxxcoin and bitcoin) at
the same time?
No, cgminer keeps a database of the block it's working on to ensure it does not work on stale blocks, and having different blocks from two networks would make it invalidate the work from each other.
Can I configure cgminer to mine with different login credentials or pools for each separate device?No.
Can I put multiple pools in the config file?Yes, check the example.conf file. Alternatively, set up everything either on the command line or via the menu after startup and choose settings->write config file and the file will be loaded one each startup
The build fails with gcc is unable to build a binary.Remove the "-march=native" component of your CFLAGS as your version of gcc does not support it. Also -O2 is capital o 2, not zero 2.
Can you implement feature X?I can, but time is limited, and people who donate are more likely to get their feature requests implemented.
Work keeps going to my backup pool even though my primary pool hasn't failed?Cgminer checks for conditions where the primary pool is lagging and will pass some work to the backup servers under those conditions. The reason for doing this is to try its absolute best to keep the devices working on something useful and not risk idle periods. You can disable this behaviour with the option --failover-only.
Is this a virus?Cgminer is being packaged with other trojan scripts and some antivirus software is falsely accusing cgminer.exe as being the actual virus, rather than whatever it is being packaged with. If you installed cgminer yourself, then you do not have a virus on your computer. Complain to your antivirus software company. They seem to be flagging even source code now from cgminer as viruses, even though text source files can't do anything by themself.
Can you modify the display to include more of one thing in the output and less of another, or can you change the quiet mode or can you add yet another output mode?Everyone will always have their own view of what's important to monitor. The defaults are very sane and I have very little interest in changing this any further. There is far more detail in the API output than can be reasonably displayed on the small console window, and using an external interface such as miner.php is much more useful for setups with many devices.
What are the best parameters to pass for X pool/hardware/device.Virtually always, the DEFAULT parameters give the best results. Most user defined settings lead to worse performance.
What happened to CPU and GPU mining?Their efficiency makes them irrelevant in the bitcoin mining world today and the author has no interest in supporting alternative coins that are better mined by these devices.
GUI version?No. The RPC interface makes it possible for someone else to write one though.
I'm having an issue. What debugging information should I provide?Start cgminer with your regular commands and add -D -T --verbose and provide the full startup output and a summary of your hardware and operating system.
Why don't you provide win64 builds?Win32 builds work everywhere and there is precisely zero advantage to a 64 bit build on windows.
Is it faster to mine on windows or linux?It makes no difference in terms of performance. It comes down to choice of operating system for their various features and your comfort level. However linux is the primary development platform and is virtually guaranteed to be more stable.
My network gets slower and slower and then dies for a minute?Try the --net-delay option if you are on a GBT server. This does nothing with stratum mining.
How do I tune for p2pool?It is also recommended to use --failover-only since the work is effectively like a different block chain, and not enabling --no-submit-stale. If mining with a BFL (fpga) minirig, it is worth adding the --bfl-range optio
I run PHP on windows to access the API with the example miner.php. Why does it fail when php is installed properly but I only get errors about Sockets not working in the logs? Read: PHP: Installation - Manual
What is a PGA?Cgminer supports 3 FPGAs: BitForce, Icarus and ModMiner. They are Field-Programmable Gate Arrays that have been programmed to do Bitcoin mining. Since the acronym needs to be only 3 characters, the "Field-" part has been skipped.
What is stratum and how do I use it?Stratum is a protocol designed for pooled mining in such a way as to minimise the amount of network communications, yet scale to hardware of any speed. With versions of cgminer 2.8.0+, if a pool has stratum support, cgminer will automatically detect it and switch to the support as advertised if it can. If you input the stratum port directly into your configuration, or use the special prefix "stratum+tcp://" instead of "http://", cgminer will ONLY try to use stratum protocol mining. The advantages of stratum to the miner are no delays in getting more work for the miner, less rejects across block changes, and far less network communications for the same amount of mining hashrate. If you do NOT wish cgminer to automatically switch to stratum protocol even if it is detected, add the --fix-protocol option.
Q: Why don't the statistics add up: Accepted, Rejected, Stale, Hardware Errors, Diff1 Work, etc. when mining greater than 1 difficulty shares?As an example, if you look at 'Difficulty Accepted' in the RPC API, the number of difficulty shares accepted does not usually exactly equal the amount of work done to find them. If you are mining at 8 difficulty, then you would expect on average to find one 8 difficulty share, per 8 single difficulty shares found. However, the number is actually random and converges over time, it is an average, not an exact value, thus you may find more or less than the expected average.
My keyboard input momentarily pauses or repeats keys every so often on windows while mining?The USB implementation on windows can be very flaky on some hardware and every time cgminer looks for new hardware to hotplug it it can cause these sorts of problems. You can disable hotplug with: --hotplug 0
What should my Work Utility (WU) be?Work utility is the product of hashrate * luck and only stabilises over a very long period of time. Assuming all your work is valid work, bitcoin mining should produce a work utility of approximately 1 per 71.6MH. This means at 5GH you should have a WU of 5000 / 71.6 or ~ 69. You cannot make your machine do "better WU" than this - it is luck related. However you can make it much worse if your machine produces a lot of hardware errors producing invalid work.
What should I build in for a generic distribution binary?There are a number of drivers that expect to be used on dedicated standalone hardware. That said, the drivers that are designed to work generically with USB on any hardware are the following:
--enable-avalon
--enable-avalon2
--enable-avalon4
--enable-avalon7
--enable-avalon8
--enable-bflsc
--enable-bitfury
--enable-cointerra
--enable-drillbit
--enable-hashfast
--enable-hashratio
--enable-icarus
--enable-klondike
How do I use the --decode function to decode a pool's coinbase?
You need to have a bitcoind with server functionality and pass it the
credentials as the first pool in your config, and pass the pool's address that
you wish to decode as the second pool configured. Note the bitcoind NEEDS the
http:// prefix.

EXECUTIVE SUMMARY ON USAGE:
Single pool:
cgminer -o http://pool:port -u username -p password
Multiple pools:
cgminer -o http://pool1:port -u pool1username -p pool1password -o http://pool2:port -u pool2usernmae -p pool2password
Single pool with a standard http proxy:
cgminer -o "http:proxy:port|http://pool:port" -u username -p password
Single pool with a socks5 proxy:
cgminer -o "socks5:proxy:port|http://pool:port" -u username -p password
Single pool with stratum protocol support:
cgminer -o stratum+tcp://pool:port -u username -p password
Solo mining to local bitcoind:
cgminer -o http://localhost:8332 -u username -p password --btc-address 15qSxP1SQcUX3o4nhkfdbgyoWEFMomJ4rZ
The list of proxy types are:
http: standard http 1.1 proxy
http0: http 1.0 proxy
socks4: socks4 proxy
socks5: socks5 proxy
socks4a: socks4a proxy
socks5h: socks5 proxy using a hostname
If you compile cgminer with a version of CURL before 7.19.4 then some of the above will
not be available. All are available since CURL version 7.19.4
If you specify the --socks-proxy option to cgminer, it will only be applied to all pools
that don't specify their own proxy setting like above
After saving configuration from the menu, you do not need to give cgminer any
arguments and it will load your configuration.
Any configuration file may also contain a single
"include" : "filename"
to recursively include another configuration file.
Writing the configuration will save all settings from all files in the output.

Basic *nix build instructions:
To actually build:
./autogen.sh # only needed if building from git repo
CFLAGS="-O2 -Wall -march=native" ./configure
make
No installation is necessary. You may run cgminer from the build
directory directly, but you may do make install if you wish to install
cgminer to a system location or location you specified.
Building for windows:
It is actually easiest to build a windows binary using cross compilation tools
provided by "mxe" available at http://mxe.cc/ (use the 32 bit one!)
Once you have followed the instructions for building mxe:
export PATH=(path/to/mxe)/usr/bin/:$PATH
CFLAGS="-O2 -Wall -W -march=i686" ./configure --host=i686-pc-mingw32
make
Native WIN32 build instructions: see windows-build.txt but these instructions
are now hopelessly out of date.

SETTING UP USB DEVICES
WINDOWS:
On windows, the direct USB support requires the installation of a WinUSB
driver (NOT the ftdi_sio driver), and attach it to the chosen USB device.
When configuring your device, plug it in and wait for windows to attempt to
install a driver on its own. It may think it has succeeded or failed but wait
for it to finish regardless. This is NOT the driver you want installed. At this
point you need to associate your device with the WinUSB driver. The easiest
way to do this is to use the zadig utility which you must right click on and
run as administrator. Then once you plug in your device you can choose the
"list all devices" from the "option" menu and you should be able to see the
device as something like: "BitFORCE SHA256 SC". Choose the install or replace
driver option and select WinUSB. You can either google for zadig or download
it from the cgminer directory in the DOWNLOADS link above.
When you first switch a device over to WinUSB with zadig and it shows that
correctly on the left of the zadig window, but it still gives permission
errors, you may need to unplug the USB miner and then plug it back in. Some
users may need to reboot at this point.
LINUX:
The short version:
sudo cp 01-cgminer.rules /etc/udev/rules.d/
The long version:
On linux, the direct USB support requires no drivers at all. However due to
permissions issues, you may not be able to mine directly on the devices as a
regular user without giving the user access to the device or by mining as
root (administrator). In order to give your regular user access, you can make
him a member of the plugdev group with the following commands:
sudo usermod -G plugdev -a `whoami`
If your distribution does not have the plugdev group you can create it with:
sudo groupadd plugdev
In order for the USB devices to instantly be owned by the plugdev group and
accessible by anyone from the plugdev group you can copy the file
"01-cgminer.rules" from the cgminer archive into the /etc/udev/rules.d
directory with the following command:
sudo cp 01-cgminer.rules /etc/udev/rules.d/
After this you can either manually restart udev and re-login, or more easily
just reboot.
OSX:
On OSX, like Linux, no drivers need to be installed. However some devices
like the bitfury USB sticks automatically load a driver thinking they're a
modem and the driver needs to be unloaded for cgminer to work:
sudo kextunload -b com.apple.driver.AppleUSBCDC
sudo kextunload -b com.apple.driver.AppleUSBCDCACMData
There may be a limit to the number of USB devices that you are allowed to start.
The following set of commands, followed by a reboot will increase that:
sudo su
touch /etc/sysctl.conf
echo kern.sysv.semume=100 >> /etc/sysctl.conf
chown root:wheel /etc/sysctl.conf
chmod 0644 /etc/sysctl.conf
Some devices need superuser access to mine on them so cgminer may need to
be started with sudo
i.e.:
sudo cgminer
---
Advanced USB options:
The --usb option can restrict how many USB devices are found:
--usb 1:2,1:3,1:4,1:*
or
--usb BAS:1,BFL:1,MMQ:0,ICA:0,KLN:0
or
--usb :10
You can only use one of the above 3
The first version
--usb 1:2,1:3,1:4,1:*
allows you to select which devices to mine on with a list of USB
bus_number:device_address
All other USB devices will be ignored
Hotplug will also only look at the devices matching the list specified and
find nothing new if they are all in use
You can specify just the USB bus_number to find all devices like 1:*
which means any devices on USB bus_number 1
This is useful if you unplug a device then plug it back in the same port,
it usually reappears with the same bus_number but a different device_address
You can see the list of all USB devices on linux with 'sudo lsusb'
Cgminer will list the recognised USB devices
with the '-n' option or the
'--usb-dump 0' option
The '--usb-dump N' option with a value of N greater than 0 will dump a lot
of details about each recognised USB device
If you wish to see all USB devices, include the --usb-list-all option
The second version
--usb BAS:1,BFL:1,MMQ:0,ICA:0,KLN:0
allows you to specify how many devices to choose based on each device
driver cgminer has - the current USB drivers are:
AVA, BAS, BFL, BF1, DRB, HFA, ICA, KLN and MMQ.
N.B. you can only specify which device driver to limit, not the type of
each device, e.g. with BAS:n you can limit how many BFL ASIC devices will
be checked, but you cannot limit the number of each type of BFL ASIC
Also note that the MMQ count is the number of MMQ backplanes you have
not the number of MMQ FPGAs
The third version
--usb :10
means only use a maximum of 10 devices of any supported USB devices
Once cgminer has 10 devices it will not configure any more and hotplug will
not scan for any more
If one of the 10 devices stops working, hotplug - if enabled, as is default
- will scan normally again until it has 10 devices
--usb :0 will disable all USB I/O other than to initialise libusb

MULTIPOOL
FAILOVER STRATEGIES WITH MULTIPOOL:
A number of different strategies for dealing with multipool setups are
available. Each has their advantages and disadvantages so multiple strategies
are available by user choice, as per the following list:
FAILOVER:
The default strategy is failover. This means that if you input a number of
pools, it will try to use them as a priority list, moving away from the 1st
to the 2nd, 2nd to 3rd and so on. If any of the earlier pools recover, it will
move back to the higher priority ones.
ROUND ROBIN:
This strategy only moves from one pool to the next when the current one falls
idle and makes no attempt to move otherwise.
ROTATE:
This strategy moves at user-defined intervals from one active pool to the next,
skipping pools that are idle.
LOAD BALANCE:
This strategy sends work to all the pools on a quota basis. By default, all
pools are allocated equal quotas unless specified with --quota. This
apportioning of work is based on work handed out, not shares returned so is
independent of difficulty targets or rejected shares. While a pool is disabled
or dead, its quota is dropped until it is re-enabled. Quotas are forward
looking, so if the quota is changed on the fly, it only affects future work.
If all pools are set to zero quota or all pools with quota are dead, it will
fall back to a failover mode. See quota below for more information.
The failover-only flag has special meaning in combination with load-balance
mode and it will distribute quota back to priority pool 0 from any pools that
are unable to provide work for any reason so as to maintain quota ratios
between the rest of the pools.
BALANCE:
This strategy monitors the amount of difficulty 1 shares solved for each pool
and uses it to try to end up doing the same amount of work for all pools.
---
QUOTAS
The load-balance multipool strategy works off a quota based scheduler. The
quotas handed out by default are equal, but the user is allowed to specify any
arbitrary ratio of quotas. For example, if all the quota values add up to 100,
each quota value will be a percentage, but if 2 pools are specified and pool0
is given a quota of 1 and pool1 is given a quota of 9, pool0 will get 10% of
the work and pool1 will get 90%. Quotas can be changed on the fly by the API,
and do not act retrospectively. Setting a quota to zero will effectively
disable that pool unless all other pools are disabled or dead. In that
scenario, load-balance falls back to regular failover priority-based strategy.
While a pool is dead, it loses its quota and no attempt is made to catch up
when it comes back to life.
To specify quotas on the command line, pools should be specified with a
semicolon separated --quota(or -U) entry instead of --url. Pools specified with
--url are given a nominal quota value of 1 and entries can be mixed.
For example:
--url poola:porta -u usernamea -p passa --quota "2;poolb:portb" -u usernameb -p passb
Will give poola 1/3 of the work and poolb 2/3 of the work.
Writing configuration files with quotas is likewise supported. To use the above
quotas in a configuration file they would be specified thus:
"pools" : [
{
"url" : "poola:porta",
"user" : "usernamea",
"pass" : "passa"
},
{
"quota" : "2;poolb:portb",
"user" : "usernameb",
"pass" : "passb"
}
]
---
SOLO MINING
Solo mining can be done efficiently as a single pool entry or a backup to
any other pooled mining and it is recommended everyone have solo mining set up
as their final backup in case all their other pools are DDoSed/down for the
security of the network. To enable solo mining, one must be running a local
bitcoind/bitcoin-qt or have one they have rpc access to. To do this, edit your
bitcoind configuration file (bitcoin.conf) with the following extra lines,
using your choice of username and password:
rpcuser=username
rpcpassword=password
Restart bitcoind, then start cgminer, pointing to the bitcoind and choose a
btc address with the following options, altering to suit their setup:
cgminer -o http://localhost:8332 -u username -p password --btc-address 15qSxP1SQcUX3o4nhkfdbgyoWEFMomJ4rZ
Note the http:// is mandatory for solo mining.
---
LOGGING
cgminer will log to stderr if it detects stderr is being redirected to a file.
To enable logging simply add 2>logfile.txt to your command line and logfile.txt
will contain the logged output at the log level you specify (normal, verbose,
debug etc.)
In other words if you would normally use:
./cgminer -o xxx -u yyy -p zzz
if you use
./cgminer -o xxx -u yyy -p zzz 2>logfile.txt
it will log to a file called logfile.txt and otherwise work the same.
There is also the -m option on linux which will spawn a command of your choice
and pipe the output directly to that command.
The WorkTime details 'debug' option adds details on the end of each line
displayed for Accepted or Rejected work done. An example would be:
<-00000059.ed4834a3 M:X D:1.0 G:17:02:38:0.405 C:1.855 (2.995) W:3.440 (0.000) S:0.461 R:17:02:47
The first 2 hex codes are the previous block hash, the rest are reported in
seconds unless stated otherwise:
The previous hash is followed by the getwork mode used M:X where X is one of
P:Pool, T:Test Pool, L:LP or B:Benchmark,
then D:d.ddd is the difficulty required to get a share from the work,
then G:hh:mm:ss:n.nnn, which is when the getwork or LP was sent to the pool and
the n.nnn is how long it took to reply,
followed by 'O' on it's own if it is an original getwork, or 'C:n.nnn' if it was
a clone with n.nnn stating how long after the work was recieved that it was cloned,
(m.mmm) is how long from when the original work was received until work started,
W:n.nnn is how long the work took to process until it was ready to submit,
(m.mmm) is how long from ready to submit to actually doing the submit, this is
usually 0.000 unless there was a problem with submitting the work,
S:n.nnn is how long it took to submit the completed work and await the reply,
R:hh:mm:ss is the actual time the work submit reply was received
If you start cgminer with the --sharelog option, you can get detailed
information for each share found. The argument to the option may be "-" for
standard output (not advisable with the ncurses UI), any valid positive number
for that file descriptor, or a filename.
To log share data to a file named "share.log", you can use either:
./cgminer --sharelog 50 -o xxx -u yyy -p zzz 50>share.log
./cgminer --sharelog share.log -o xxx -u yyy -p zzz
For every share found, data will be logged in a CSV (Comma Separated Value)
format:
timestamp,disposition,target,pool,dev,thr,sharehash,sharedata
For example (this is wrapped, but it's all on one line for real):
1335313090,reject,
ffffffffffffffffffffffffffffffffffffffffffffffffffffffff00000000,
http://localhost:8337,ASC0,0,
6f983c918f3299b58febf95ec4d0c7094ed634bc13754553ec34fc3800000000,

---
BENCHMARK
The --benchmark option hashes a single fixed work item over and over and does
not submit shares to any pools.
The --benchfile
The format of the work file is:
version,merkleroot,prevhash,diffbits,noncetime
Any empty line or any line starting with '#' or '/' is ignored.
When it reaches the end of the file it continues back at the top.
The format of the data items matches the byte ordering and format of the
the bitcoind getblock RPC output.
An example file containing bitcoin block #1 would be:
# Block 1
1,0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098,00000000001
9d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f,1d00ffff,1231469665
However, the work data should be one line without the linebreak in the middle
If you use --benchfile
for each nonce found, showing the nonce value in decimal and hex and the work
used to find it in hex.

FAQ
Q: Help, I've started cgminer and everything reads zero!?
A: Welcome to bitcoin mining. Your computer by itself cannot mine bitcoin no
matter how powerful it is. You have to purchase dedicated mining hardware
called ASICs to plug into your computer. See Q regarding ASICs below.
Q: I have multiple USB stick devices but I can't get them all to work at once?
A: Very few USB hubs deliver the promised power required to run as many devices
as they fit if all of them draw power from USB.
Q: I've plugged my devices into my USB hub but nothing shows up?
A: RPis and Windows have incomplete or non-standard USB3 support so they may
never work. It may be possible to get a USB3 hub to work by plugging it into
a USB2 hub. When choosing a hub, USB2 hubs are preferable whenever possible
due to better support all round.
Q: Can I mine on servers from different networks (eg xxxcoin and bitcoin) at
the same time?
A: No, cgminer keeps a database of the block it's working on to ensure it does
not work on stale blocks, and having different blocks from two networks would
make it invalidate the work from each other.
Q: Can I configure cgminer to mine with different login credentials or pools
for each separate device?
A: No.
Q: Can I put multiple pools in the config file?
A: Yes, check the example.conf file. Alternatively, set up everything either on
the command line or via the menu after startup and choose settings->write
config file and the file will be loaded one each startup.
Q: The build fails with gcc is unable to build a binary.
A: Remove the "-march=native" component of your CFLAGS as your version of gcc
does not support it. Also -O2 is capital o 2, not zero 2.
Q: Can you implement feature X?
A: I can, but time is limited, and people who donate are more likely to get
their feature requests implemented.
Q: Work keeps going to my backup pool even though my primary pool hasn't
failed?
A: Cgminer checks for conditions where the primary pool is lagging and will
pass some work to the backup servers under those conditions. The reason for
doing this is to try its absolute best to keep the devices working on something
useful and not risk idle periods. You can disable this behaviour with the
option --failover-only.
Q: Is this a virus?
A: Cgminer is being packaged with other trojan scripts and some antivirus
software is falsely accusing cgminer.exe as being the actual virus, rather
than whatever it is being packaged with. If you installed cgminer yourself,
then you do not have a virus on your computer. Complain to your antivirus
software company. They seem to be flagging even source code now from cgminer
as viruses, even though text source files can't do anything by themself.
Q: Can you modify the display to include more of one thing in the output and
less of another, or can you change the quiet mode or can you add yet another
output mode?
A: Everyone will always have their own view of what's important to monitor.
The defaults are very sane and I have very little interest in changing this
any further. There is far more detail in the API output than can be reasonably
displayed on the small console window, and using an external interface such
as miner.php is much more useful for setups with many devices.
Q: What are the best parameters to pass for X pool/hardware/device.
A: Virtually always, the DEFAULT parameters give the best results. Most user
defined settings lead to worse performance.
Q: What happened to CPU and GPU mining?
A: Their efficiency makes them irrelevant in the bitcoin mining world today
and the author has no interest in supporting alternative coins that are better
mined by these devices.
Q: GUI version?
A: No. The RPC interface makes it possible for someone else to write one
though.
Q: I'm having an issue. What debugging information should I provide?
A: Start cgminer with your regular commands and add -D -T --verbose and provide
the full startup output and a summary of your hardware and operating system.
Q: Why don't you provide win64 builds?
A: Win32 builds work everywhere and there is precisely zero advantage to a
64 bit build on windows.
Q: Is it faster to mine on windows or linux?
A: It makes no difference in terms of performance. It comes down to choice of
operating system for their various features and your comfort level. However
linux is the primary development platform and is virtually guaranteed to be
more stable.
Q: My network gets slower and slower and then dies for a minute?
A; Try the --net-delay option if you are on a GBT server. This does nothing
with stratum mining.
Q: How do I tune for p2pool?
A: It is also recommended to use --failover-only since the work is effectively
like a different block chain, and not enabling --no-submit-stale. If mining with
a BFL (fpga) minirig, it is worth adding the --bfl-range option.
Q: I run PHP on windows to access the API with the example miner.php. Why does
it fail when php is installed properly but I only get errors about Sockets not
working in the logs?
A: http://us.php.net/manual/en/sockets.installation.php
Q: What is a PGA?
A: Cgminer supports 3 FPGAs: BitForce, Icarus and ModMiner.
They are Field-Programmable Gate Arrays that have been programmed to do Bitcoin
mining. Since the acronym needs to be only 3 characters, the "Field-" part has
been skipped.
Q: What is an ASIC?
A: They are Application Specify Integrated Circuit devices and provide the
highest performance per unit power due to being dedicated to only one purpose.
They are the only meaningful way to mine bitcoin today.
Q: What is stratum and how do I use it?
A: Stratum is a protocol designed for pooled mining in such a way as to
minimise the amount of network communications, yet scale to hardware of any
speed. With versions of cgminer 2.8.0+, if a pool has stratum support, cgminer
will automatically detect it and switch to the support as advertised if it can.
If you input the stratum port directly into your configuration, or use the
special prefix "stratum+tcp://" instead of "http://", cgminer will ONLY try to
use stratum protocol mining. The advantages of stratum to the miner are no
delays in getting more work for the miner, less rejects across block changes,
and far less network communications for the same amount of mining hashrate. If
you do NOT wish cgminer to automatically switch to stratum protocol even if it
is detected, add the --fix-protocol option.
Q: Why don't the statistics add up: Accepted, Rejected, Stale, Hardware Errors,
Diff1 Work, etc. when mining greater than 1 difficulty shares?
A: As an example, if you look at 'Difficulty Accepted' in the RPC API, the number
of difficulty shares accepted does not usually exactly equal the amount of work
done to find them. If you are mining at 8 difficulty, then you would expect on
average to find one 8 difficulty share, per 8 single difficulty shares found.
However, the number is actually random and converges over time, it is an average,
not an exact value, thus you may find more or less than the expected average.
Q: My keyboard input momentarily pauses or repeats keys every so often on
windows while mining?
A: The USB implementation on windows can be very flaky on some hardware and
every time cgminer looks for new hardware to hotplug it it can cause these
sorts of problems. You can disable hotplug with:
--hotplug 0
Q: What should my Work Utility (WU) be?
A: Work utility is the product of hashrate * luck and only stabilises over a
very long period of time. Assuming all your work is valid work, bitcoin mining
should produce a work utility of approximately 1 per 71.6MH. This means at
5GH you should have a WU of 5000 / 71.6 or ~ 69. You cannot make your machine
do "better WU" than this - it is luck related. However you can make it much
worse if your machine produces a lot of hardware errors producing invalid work.
Q: What should I build in for a generic distribution binary?
A: There are a number of drivers that expect to be used on dedicated standalone
hardware. That said, the drivers that are designed to work generically with
USB on any hardware are the following:
--enable-avalon
--enable-avalon2
--enable-avalon4
--enable-avalon7
--enable-avalon8
--enable-bflsc
--enable-bitfury
--enable-cointerra
--enable-drillbit
--enable-hashfast
--enable-hashratio
--enable-icarus
--enable-klondike
Q: How do I use the --decode function to decode a pool's coinbase?
A: You need to have a bitcoind with server functionality and pass it the
credentials as the first pool in your config, and pass the pool's address that
you wish to decode as the second pool configured. Note the bitcoind NEEDS the
http:// prefix.
e.g.:
./cgminer -o http://localhost:8332 -u user -p pass -o solo.ckpool.org:3333 -u 15qSxP1SQcUX3o4nhkfdbgyoWEFMomJ4rZ --decode
