Stratum protocol is also used for pooled mining as a replacement for obsolete [[Getwork|getwork]] protocol. Full mining service specification is available on [http://mining.bitcoin.cz/stratum-mining/ Slush's pool website]. Other examples are available on [https://www.btcguild.com/new_protocol.php BTC Guild's website].

*Restart Cgminer:<br /> # /etc/init.d/cgminer restart<br /> <br /> If your avalon does not mine properly, please run Cgminer in debug mode with -D --verbose option. For example:<br /> # cgminer -S /dev/ttyUSB0 -o stratum.btcguild.com:3333 -O xxxx:yyyy -D --verbose --avalon-options 115200:24:10:45:282 --api-allow &quot;W:0/0&quot; --api-listen 2&gt;/tmp/cgminer-debug.log<br /> <br /> == TP-LINK TL-WR703N ==<br /> There is a modify version of TP-LINK TP-WR703N inside Avalon. cgminer running at 703n, this 703n have 64MB ram and modified power supply. it power from the usb-client side(we moved a 0R resistor from '''J1''' to '''R113''' for that)<br /> <br /> Why there is a ugly USB HUB there? you can find more information about AR9331's usb stability issue [https://forum.openwrt.org/viewtopic.php?id=39956 here].<br /> <br /> === How to reflash ===<br /> # Download latest Avalon [http://downloads.qi-hardware.com/people/xiangfu/avalon/latest/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin image] to your PC.<br /> # Goto:<br /> System -&gt; Backup / Flash Firmware -&gt; Flash new firmware image (make sure '''Keep settings''' is checked)<br /> # Select the image you just download. then compare the md5 in next page. if everything fine. click '''Proceed'''<br /> <br /> '''Attention:''' To avoid your WR703N become a brick, during flash your WR703N be careful DO NOT power off avalon, and DO NOT break your network connection. Just wait there till you see OpenWrt login web page again.<br /> <br /> '''Attention:''' If not essential please do not re-Flash your Avalon. Because not all of WR703N issue could be resolved by reset button. If you want to play WR703N I would like to recommend you order a standalone TP-LINK WR703N from ebay or somewhere for studying purpose.<br /> <br /> == WIFI or Ethernet Cable ? ==<br /> Avalon shipped with a 9db antenna after connect it to WR703N usually could establish good wireless connection with your WIFI router. But if for some reason you would like to use Ethernet Cable to connect Avalon with your network, please login OpenWrt and configure the LAN port:<br /> Network -&gt; Interfaces -&gt; LAN -&gt; Edit -&gt; Common Configuration -&gt; General Setup<br /> Disable the DHCP on Lan port<br /> <br /> '''Attention:''' You need to configure it correctly based on your own network enviroment. If anything wrong you might could not access your WR703N any more.<br /> <br /> == Start to mine ==<br /> To maximize your Avalon miner's performance, it is recommended that you choose pools with the stratum protocol supported. The default mining pool configured in Avalon is ozco.in. To change it login to OpenWrt:<br /> Status -&gt; Cgminer Configuration<br /> Click &quot;Save &amp; Apply&quot; to save your update and restart cgminer immediately<br /> <br /> Currently the stratum pools that could work stable with Avalon are:<br /> * [http://50btc.com/ 50BTC.com]<br /> * [https://bitcointalk.org/index.php?topic=158105.0 Solo mining with Eloipool]<br /> * [http://bitminter.com BitMinter]<br /> * [http://eligius.st Eligius]<br /> * [https://www.ozcoin.net Ozcoin]<br /> * [http://www.btcguild.com btcguild]<br /> * [http://mining.bitcoin.cz slush's pool]<br /> * [http://www.triplemining.com Triplemining]<br /> <br /> To get more information about how to configure specific pools, please check their website. If you run multiple Avalons, we recommend that you create a dedicated worker for each of them. This will make it easier to monitor your Avalons through the pool's website and identify possible problems.<br /> <br /> == Source code ==<br /> * https://github.com/BitSyncom/cgminer/tree/avalon<br /> * https://github.com/BitSyncom/cgminer-openwrt-packages<br /> * https://github.com/BitSyncom/luci/tree/cgminer-webui<br /> * https://github.com/BitSyncom/avalon-extras<br /> <br /> == FPGA controller ==<br /> === V1.0 ~ V1.2 ===<br /> About '''P5''' jumper: close this jumper will supply 5V to the USB-B port. in this system, the controller board power the 703N from the client side. if you connect the controller itself to a PC, you better remove the jumper.<br /> <br /> === V1.5 ===<br /> [[File:Avalon fpga controller v1.5.jpg | 320px]] [[File:Avalon fpga controller v1.5 usb hub.jpg | 320px]]<br /> * Remove the '''[http://www3.picturepush.com/photo/a/13207881/1024/Anonymous/avf1.png F1(Fuse)]''' for fix the USB-HUB chip overheat, <br /> # if you are batch2 user and your received Avalon between '''Apr 26 2013 ~ May 31 2013'''<br /> # the FPGA controller is '''1.5'''<br /> # your FPGA contoller board still have '''F1 mounted'''<br /> you need do this by yourself. removing F1 will not make the usb hub stop working, F1 powers the USB-A1 plug (which is normally unused), more info please checkout [https://github.com/BitSyncom/avalon-ref/issues/5 here]<br /> <br /> === V1.51 ===<br /> * Fixed USB-HUB chip overheat, NO NEEDS remove F1 anymore<br /> <br /> == Update FPGA controller firmware (NOT FINISHED/FULL DOCUMENT YET) ==<br /> [[File:Fpga-controller-jtag-pins.png]]<br /> <br /> * Update under Avalon 703N: http://downloads.qi-hardware.com/people/xiangfu/avalon/fpga-controller/<br /> * http://en.qi-hardware.com/w/images/f/ff/M1_JTAGserialpod_Pins.JPG<br /> <br /> #mini-jtag load xc6slx16-2-ftg256.bscan_s6_spi_isf_ext.bit &amp;&amp; sleep 1 &amp;&amp; xc3sprog -c qi -v -I fpga_controller_2013-05-02-D.bit<br /> xc3sprog -c qi xc6slx16-2-ftg256.bscan_s6_spi_isf_ext.bit &amp;&amp; sleep 1 &amp;&amp; xc3sprog -c qi -v -I fpga_controller_2013-05-02-D.bit<br /> xc3sprog -c qi -v -I file.bin:R:0:bin<br /> dd if=file.bin bs=68 skip=1 of=file2.bin<br /> xc3sprog -c qi -v -I file2.bin:w:0:bin<br /> rm -f file.bin file2.bin<br /> <br /> == P2Pool Operation with Avalon ==<br /> There is an /avalon branch Forrest committed to the p2pool github repository. Make sure that is checked out.<br /> <br /> Next, the following option may need to be passed to Avalon's cgminer:<br /> '''--fix-protocol''': Do not redirect to a different getwork protocol (eg. stratum)<br /> <br /> The current /avalon branch from Forrest is likely now functional. Please test and report your findings to the IRC channel.<br /> <br /> '''NOTE''': The best performance the small handful of users who got this working have reported is still about 25-30% DOA against P2Pool (versus the usual DOA of 8-15% or so.) So it's close to desired, but be aware that getting things working in this state currently requires command-line skills and the ability to check-out branches from p2pool's git repository. For the moment, your most efficient options are solo-mining with local pool software, or just using one of the online pools.<br /> <br /> == About [usb 1-1: clear tt 1 (8030) error -71] ==<br /> Not all 703n have this problem. ignore this section if you never meet this error<br /> <br /> * There is a power issue with the 703N, The 703N is drawing to much power it caused the USB HUB chip on Senseless's FPGA controller to nearly destroy itself.

A hybrid between PPLNS and Geometric reward types that enables to operator to absorb some of the variance risk. Operator receives portion of payout on short rounds and returns it on longer rounds to normalize payments. [https://bitcointalk.org/index.php?topic=39497.0]<br /> * '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.<br /> * '''PPLNS''' - Pay Per Last N Shasres. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.<br /> * '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BC. Since finding a block requires &lt;current difficulty&gt; shares ''on average'', a PPS method with 0% fee would be 25 BTC divided by &lt;current difficulty&gt;. It is risky for pool operators, hence the fee is highest.<br /> * '''SMPPS''' - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''ESMPPS''' - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed. [http://forum.bitcoin.org/index.php?topic=12181.msg378851#msg378851]<br /> * '''RSMPPS''' - Recent Shared Maximum Pay Per Share. Like SMPPS, but system aims to prioritize the most recent miners first. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''CPPSRB''' - Capped Pay Per Share with Recent Backpay. [http://eligius.st/wiki/index.php/Capped_PPS_with_Recent_Backpay]<br /> * '''POT''' - Pay On Target. A high variance PPS variant that pays on the difficulty of work retuened to pool rather than the difficulty of work served by pool [https://bitcointalk.org/index.php?topic=131376.0]<br /> * '''Score''' - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time ''t'' since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)<br /> [http://eligius.st/~luke-jr/samples/800MH-3/ Visual examples of the various payout methods]<br /> <br /> {| class=&quot;wikitable sortable&quot;<br /> |-<br /> !

A hybrid between PPLNS and Geometric reward types that enables to operator to absorb some of the variance risk. Operator receives portion of payout on short rounds and returns it on longer rounds to normalize payments. [https://bitcointalk.org/index.php?topic=39497.0]<br /> * '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.<br /> * '''PPLNS''' - Pay Per Last N Shasres. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.<br /> * '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BC. Since finding a block requires &lt;current difficulty&gt; shares ''on average'', a PPS method with 0% fee would be 25 BTC divided by &lt;current difficulty&gt;. It is risky for pool operators, hence the fee is highest.<br /> * '''SMPPS''' - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''ESMPPS''' - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed. [http://forum.bitcoin.org/index.php?topic=12181.msg378851#msg378851]<br /> * '''RSMPPS''' - Recent Shared Maximum Pay Per Share. Like SMPPS, but system aims to prioritize the most recent miners first. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''CPPSRB''' - Capped Pay Per Share with Recent Backpay. [http://eligius.st/wiki/index.php/Capped_PPS_with_Recent_Backpay]<br /> * '''POT''' - Pay On Target. A high variance PPS variant that pays on the difficulty of work retuened to pool rather than the difficulty of work served by pool [https://bitcointalk.org/index.php?topic=131376.0]<br /> * '''Score''' - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time ''t'' since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)<br /> [http://eligius.st/~luke-jr/samples/800MH-3/ Visual examples of the various payout methods]<br /> <br /> {| class=&quot;wikitable sortable&quot;<br /> |-<br /> !

A hybrid between PPLNS and Geometric reward types that enables to operator to absorb some of the variance risk. Operator receives portion of payout on short rounds and returns it on longer rounds to normalize payments. [https://bitcointalk.org/index.php?topic=39497.0]<br /> * '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.<br /> * '''PPLNS''' - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.<br /> * '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BC. Since finding a block requires &lt;current difficulty&gt; shares ''on average'', a PPS method with 0% fee would be 25 BTC divided by &lt;current difficulty&gt;. It is risky for pool operators, hence the fee is highest.<br /> * '''SMPPS''' - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''ESMPPS''' - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed. [http://forum.bitcoin.org/index.php?topic=12181.msg378851#msg378851]<br /> * '''RSMPPS''' - Recent Shared Maximum Pay Per Share. Like SMPPS, but system aims to prioritize the most recent miners first. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''CPPSRB''' - Capped Pay Per Share with Recent Backpay. [http://eligius.st/wiki/index.php/Capped_PPS_with_Recent_Backpay]<br /> * '''POT''' - Pay On Target. A high variance PPS variant that pays on the difficulty of work retuened to pool rather than the difficulty of work served by pool [https://bitcointalk.org/index.php?topic=131376.0]<br /> * '''Score''' - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time ''t'' since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)<br /> [http://eligius.st/~luke-jr/samples/800MH-3/ Visual examples of the various payout methods]<br /> <br /> {| class=&quot;wikitable sortable&quot;<br /> |-<br /> !

A hybrid between PPLNS and Geometric reward types that enables to operator to absorb some of the variance risk. Operator receives portion of payout on short rounds and returns it on longer rounds to normalize payments. [https://bitcointalk.org/index.php?topic=39497.0]<br /> * '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.<br /> * '''PPLNS''' - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.<br /> * '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BC. Since finding a block requires &lt;current difficulty&gt; shares ''on average'', a PPS method with 0% fee would be 50 BTC divided by &lt;current difficulty&gt;. It is risky for pool operators, hence the fee is highest.<br /> * '''SMPPS''' - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''ESMPPS''' - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed. [http://forum.bitcoin.org/index.php?topic=12181.msg378851#msg378851]<br /> * '''RSMPPS''' - Recent Shared Maximum Pay Per Share. Like SMPPS, but system aims to prioritize the most recent miners first. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''CPPSRB''' - Capped Pay Per Share with Recent Backpay. [http://eligius.st/wiki/index.php/Capped_PPS_with_Recent_Backpay]<br /> * '''Score''' - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time ''t'' since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)<br /> [http://eligius.st/~luke-jr/samples/800MH-3/ Visual examples of the various payout methods]<br /> <br /> {| class=&quot;wikitable sortable&quot;<br /> |-<br /> !

A hybrid between PPLNS and Geometric reward types that enables to operator to absorb some of the variance risk. Operator receives portion of payout on short rounds and returns it on longer rounds to normalize payments. [https://bitcointalk.org/index.php?topic=39497.0]<br /> * '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.<br /> * '''PPLNS''' - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.<br /> * '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BC. Since finding a block requires &lt;current difficulty&gt; shares ''on average'', a PPS method with 0% fee would be 50 BTC divided by &lt;current difficulty&gt;. It is risky for pool operators, hence the fee is highest.<br /> * '''SMPPS''' - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''ESMPPS''' - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed. [http://forum.bitcoin.org/index.php?topic=12181.msg378851#msg378851]<br /> * '''RSMPPS''' - Recent Shared Maximum Pay Per Share. Like SMPPS, but system aims to prioritize the most recent miners first. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''CPPSRB''' - Capped Pay Per Share with Recent Backpay. [http://eligius.st/wiki/index.php/Capped_PPS_with_Recent_Backpay]<br /> * '''Score''' - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time ''t'' since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)<br /> [http://eligius.st/~luke-jr/samples/800MH-3/ Visual examples of the various payout methods]<br /> <br /> {| class=&quot;wikitable sortable&quot;<br /> |-<br /> !

A hybrid between PPLNS and Geometric reward types that enables to operator to absorb some of the variance risk. Operator receives portion of payout on short rounds and returns it on longer rounds to normalize payments. [https://bitcointalk.org/index.php?topic=39497.0]<br /> * '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.<br /> * '''PPLNS''' - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.<br /> * '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BC. Since finding a block requires &lt;current difficulty&gt; shares ''on average'', a PPS method with 0% fee would be 50 BTC divided by &lt;current difficulty&gt;. It is risky for pool operators, hence the fee is highest.<br /> * '''SMPPS''' - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''ESMPPS''' - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed. [http://forum.bitcoin.org/index.php?topic=12181.msg378851#msg378851]<br /> * '''RSMPPS''' - Recent Shared Maximum Pay Per Share. Like SMPPS, but system aims to prioritize the most recent miners first. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''CPPSRB''' - Capped Pay Per Share with Recent Backpay. [http://eligius.st/wiki/index.php/Capped_PPS_with_Recent_Backpay]<br /> * '''Score''' - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time ''t'' since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)<br /> [http://eligius.st/~luke-jr/samples/800MH-3/ Visual examples of the various payout methods]<br /> <br /> {| class=&quot;wikitable sortable&quot;<br /> |-<br /> !

explanation:<br /> * '''DGM''' - Double Geometric Method. A hybrid between PPLNS and Geometric reward types that enables to operator to absorb some of the variance risk. Operator receives portion of payout on short rounds and returns it on longer rounds to normalize payments. [https://bitcointalk.org/index.php?topic=39497.0]<br /> * '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.<br /> * '''PPLNS''' - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.<br /> * '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BC. Since finding a block requires &lt;current difficulty&gt; shares ''on average'', a PPS method with 0% fee would be 50 BTC divided by &lt;current difficulty&gt;. It is risky for pool operators, hence the fee is highest.<br /> * '''SMPPS''' - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''ESMPPS''' - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed. [http://forum.bitcoin.org/index.php?topic=12181.msg378851#msg378851]<br /> * '''RSMPPS''' - Recent Shared Maximum Pay Per Share. Like SMPPS, but system aims to prioritize the most recent miners first. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''CPPSRB''' - Capped Pay Per Share with Recent Backpay.<br /> * '''Score''' - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time ''t'' since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool.

A hybrid between PPLNS and Geometric reward types that enables to operator to absorb some of the variance risk. Operator receives portion of payout on short rounds and returns it on longer rounds to normalize payments. [https://bitcointalk.org/index.php?topic=39497.0]<br /> * '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.<br /> * '''PPLNS''' - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.<br /> * '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BC. Since finding a block requires &lt;current difficulty&gt; shares ''on average'', a PPS method with 0% fee would be 50 BTC divided by &lt;current difficulty&gt;. It is risky for pool operators, hence the fee is highest.<br /> * '''SMPPS''' - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''ESMPPS''' - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed. [http://forum.bitcoin.org/index.php?topic=12181.msg378851#msg378851]<br /> * '''CPPSRB''' - Capped Pay Per Share with Recent Backpay.<br /> * '''Score''' - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time ''t'' since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)<br /> [http://eligius.st/~luke-jr/samples/800MH-3/ Visual examples of the various payout methods]<br /> <br /> {| class=&quot;wikitable sortable&quot;<br /> |-<br /> !

Each submitted share is worth certain amount of BC. Since finding a block requires &lt;current difficulty&gt; shares ''on average'', a PPS method with 0% fee would be 50 BTC divided by &lt;current difficulty&gt;. It is risky for pool operators, hence the fee is highest.<br /> * '''SMPPS''' - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns. [http://.st/wiki/index.php/Shared_Maximum_PPS]<br /> * '''ESMPPS''' - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed. [http://forum.bitcoin.org/index.php?topic=12181.msg378851#msg378851]<br /> * '''CPPSRB''' - Capped Pay Per Share with Recent Backpay.<br /> * '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.<br /> * '''PPLNS''' - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.<br /> * '''Score''' - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time ''t'' since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)<br /> [http://eligius.st/~luke-jr/samples/800MH-3/ Visual examples of the various payout methods]<br /> <br /> {| class=&quot;wikitable sortable&quot;<br /> |-<br /> !
