<div>Reward types & explanation:<br />
* '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BTC. Since finding a block requires <current difficulty> shares ''on average'', a PPS method with 0% fee would be 50 BTC divided by <current difficulty>. 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 />

<div>Reward types & explanation:<br />
* '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BTC. Since finding a block requires <current difficulty> shares ''on average'', a PPS method with 0% fee would be 50 BTC divided by <current difficulty>. 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 />

* '''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 />

<div>Reward types & explanation:<br />
* '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BTC. Since finding a block requires <current difficulty> shares ''on average'', a PPS method with 0% fee would be 50 BTC divided by <current difficulty>. 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 />
* '''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 />

<hr />
<div>'''Pooled mining''' is an approach where multiple generating clients contribute to the generation of a block, and then split the block reward according the contributed processing power. Pooled mining effectively reduces the granularity of the block generation reward, spreading it out more smoothly over time.<br />
<br />
==Introduction==<br />
<br />
With increasing generation difficulty, mining with lower-performance devices can take a very long time before block generation, on average. For example, with a mining speed of 1000 Khps, at a difficulty of 14484 (which was in effect at the end of December, 2010), the average time to generate a block is almost 2 years. <br />
<br />
To provide a more smooth incentive to lower-performance miners, several pooled miners, using different approaches, have been created. With a mining pool, a lot of different people contribute to generating a block, and the reward is then split among them according to their processing contribution. This way, instead of waiting for years to generate 50btc in a block, a smaller miner may get a fraction of a bitcoin on a more regular basis.<br />
<br />
A '''share''' is awarded by the mining pool to the clients who present a valid [[proof of work]] of the same type as the proof of work that is used for creating [[block|blocks]], but of lesser complexity, so that it requires less time on average to generate.<br />
<br />
==Pooled mining approaches==<br />
<br />
The problem with pooled mining is that steps must be taken to prevent cheating by the clients and the server. Currently there are several different approaches used.<br />
<br />
===The slush approach===<br />
<br />
[[Bitcoin Pooled Mining]] (BPM), sometimes referred to as "slush's pool", follows a score-based method. Older shares (from beginning of the round) has lower weight than newer shares, which demotivate cheater from switching between pools inside one round.<br />
<br />
===The puddinpop approach===<br />
<br />
(As of February, 2011, there are no puddinpop pools running.)<br />
<br />
Another approach is the 'metahash' technique, used by puddinpop's [[remote miner]]. Clients generate hashes, and also submit 'metahashes', which are hashes of a large chunk of generated hashes. The server checks that the metahashes are correct (in a round-robin fashion, picking up a metahash from a client that hasn't been checked on the longest), thus preventing clients from simply claiming that they have done work without actually doing the work. The withholding of good blocks by the clients is prevented via the server being in possession of the private key, just as in the previous approach. Rewards are distributed based on the number of metahashes submitted by the clients.<br />
<br />
The generated blocks contain multiple keys in the generation transaction, giving fractional bitcoin amounts to each key, in proportion to their hashing contribution for that block.<br />
<br />
===The Pay-per-Share approach===<br />
<br />
The Pay-per-Share (PPS) approach, first described by [[BitPenny]], is to offer an instant flat payout for each share that is solved. The payout is offered from the pool's existing balance and can therefore be withdrawn immediately, without waiting for a block to be solved or confirmed. The possibility of cheating the miners by the pool operator and by timing attacks is thus completely eliminated. <br />
<br />
This method results in the least possible variance for miners while transferring all risk to the pool operator. The resulting possibility of loss for the server is offset by setting the payout lower than the full expected value.<br />
<br />
===Luke-Jr's approach ("[[Eligius]]")===<br />
[[User:Luke-Jr|Luke]] came up with a third approach borrowing strengths from the earlier two.<br />
Like slush's approach, miners submit proofs-of-work to earn shares.<br />
Like puddinpop's approach, the pool pays out immediately via block generation.<br />
When distributing block rewards, it is divided equally among all shares since the last valid block.<br />
Unlike any preexisting pool approach, this means that the shares contributed toward orphaned blocks are recycled into the next block's shares.<br />
In order to spare participating miners from transaction fees, rewards are only paid out if a miner has earned at least 1 BTC. If the amount owed is less, it will be added to the earnings of a later block (which may then total over 1 BTC).<br />
If a miner does not submit a share for over a week, the pool sends any balance remaining, regardless of its size.<br />
<br />
===The Triplemining approach===<br />
The [[Triplemining]] approach is to bring together a medium-sized pool with no fees and clever redistribution of 1% of every found block to allow your share to grow more rapidly than on any other bitcoin mining pool. <br />
<br />
For every found block, Triplemining redistributes 1% of the profits to all minipool owners (people with 1 or more friends mining with them). The redistribution is connected to the shares found by the members of the minipool. So if the hash rate of the minipool members equals or is bigger than yours, the part in the redistribution will be equally bigger.<br />
<br />
===P2Pool approach===<br />
<br />
[[P2Pool]] mining nodes work on a chain of shares similar to Bitcoin’s blockchain. There is no central point of failure and thus P2Pool becomes DoS resistant.<br />
<br />
P2Pool works different from existing mining pool technologies — each node works on a block that includes payouts to the previous shares’ owners and the node itself. 99% of the block reward (the 50BTC reward plus any included transaction fees) is distributed evenly to miners based on work done recently. An additional 0.5% is awarded to the node which solves the block.<br />
<br />
===Comparison===<br />
<br />
The cooperative mining approach (slush and Luke-Jr) uses a lot less resources on the pool server, since rather than continuously checking metahashes, all that has to be checked is the validity of submitted shares. The number of shares sent can be adjusted by adjusting the artificial difficulty level.<br />
<br />
Further, the cooperative mining approach allows the clients to use existing miners without any modification, while the puddinpop approach requires the custom pool miner, which are as of now not as efficient on GPU mining as the existing GPU miners.<br />

Additionally, the puddinpop and Luke-Jr approaches of distributing the earnings by way of including precise sub-cent amounts in the generation transaction for the participants, results in the presence of sub-cent bitcoin amounts in your wallet, which are liable to disappear (as unnecessary fees) later due to a bug in old (before 0.3.21) bitcoin nodes. (E.g., if you have a transaction with 0.052 in your wallet, and you later send .05 to someone, your .002 will disappear.).<br />
<br />
Puddinpop and Luke-Jr miners receive coins directly, which eliminates the delay in receiving earnings that is required on slush-based mining servers. However, using some [[eWallet]] services like MyBitcoin for generated coin will cause those coins to be lost.<br />

<div>Shows an estimate of the amount of time, on average, that you will need to do mining at the specified hash rate before you will generate a [[blocks|block]] and earn bitcoins. Additionally, the optimistic (50% probability) and pessimistic (95% probability) estimates are shown as well.<br />
<br />
The hash rate refers to the rate that your mining hardware is performing at as reported by your miner software or from an estimate obtained from the [[mining hardware comparison]] tables.<br />
<br />
The calculation is performed like this:<br />
*Get the current [[target]].<br />
*Divide by 115792089237316195423570985008687907853269984665640564039457584007913129639935, which is the maximum value of a 256-bit number. You now have the probability of a single hash solving a block.<br />
*Take the reciprocal of the probability to get the average number of hashes to solve a block.<br />
*Divide the average number of hashes by your hash/s (''not'' khash/s) to get the average number of seconds required to solve a block.<br />

<div>Reward types & explanation:<br />
* '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BTC. Since finding a block requires <current difficulty> shares ''on average'', a PPS method with 0% fee would be 50 BTC divided by <current difficulty>. 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 />
* '''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 />

<div>''See also: [[target]]''<br />
<br />
=== What is "difficulty"? ===<br />
<br />
Difficulty is a measure of how difficult it is to find a new [[block]] compared to the easiest it can ever be.<br />
<br />
=== How often does the difficulty change? ===<br />
<br />
Every 2016 [[block|blocks]].<br />
<br />
=== What is the formula for difficulty? ===<br />
<br />
difficulty = maximum_target / current_target <br />
<br />
(target is a 256 bit number)<br />
<br />
===How is difficulty stored in blocks?===<br />
<br />
Each block stores a packed representation (called "Bits") for its actual hexadecimal [[target]]. The target can be derived from it via a predefined formula. For example, if the packed target in the block is 0x1b0404cb, the hexadecimal target is<br />
0x0404cb * 2**(8*(0x1b - 3)) = 0x00000000000404CB000000000000000000000000000000000000000000000000<br />
<br />
Note that the 0x0404cb value is a signed value in this format. The largest legal value for this field is 0x7fffff. To make a larger value you must shift it down one full byte. Also 0x008000 is the smallest positive valid value.<br />
<br />
The highest possible target (difficulty 1) is defined as 0x1d00ffff, which gives us a hex target of<br />
0x00ffff * 2**(8*(0x1d - 3)) = 0x00000000FFFF0000000000000000000000000000000000000000000000000000<br />
<br />
So the difficulty at 0x1b0404cb is therefore:<br />
0x00000000FFFF0000000000000000000000000000000000000000000000000000 /<br />
0x00000000000404CB000000000000000000000000000000000000000000000000 <br />
= 16307.420938523983<br />
<br />
=== What is the current difficulty? ===<br />
[http://blockexplorer.com/q/getdifficulty Current difficulty], as output by BitCoin's getDifficulty.<br />
<br />
[http://blockexplorer.com/q/estimate Estimated next difficulty]<br />
<br />
[http://bitcoin.sipa.be Graphs]<br />
<br />
=== What is the maximum difficulty? ===<br />
The maximum difficulty is roughly: maximum_target / 1, which is a ridiculously huge number (about 2^224). <br />
<br />
The actual maximum difficulty is when current_target=0, but we would not be able to calculate the difficulty if that happened. (fortunately it never will, so we're ok.)<br />
<br />
=== Can the difficulty go down? ===<br />
Yes it can. See discussion in [[target]].<br />
<br />
=== What is the minimum difficulty? ===<br />
The minimum difficulty, when the target is at the maximum allowed value, is 1.<br />
<br />
=== What network hash rate results in a given difficulty? ===<br />
The difficulty is adjusted every 2016 blocks based on the time it took to find the previous 2016 blocks. At the desired rate of one block each 10 minutes, 2016 blocks would take exactly two weeks to find. If the previous 2016 blocks took more than two weeks to find, the difficulty is reduced. If they took less than two weeks, the difficulty is increased. The change in difficulty is in proportion to the amount of time over or under two weeks the previous 2016 blocks took to find.<br />
<br />
To find a block, the hash must be less than the target. The hash is effectively a random number between 0 and 2**256-1. The offset for difficulty 1 is<br />
0xffff * 2**208<br />
and for difficulty D is<br />
0xffff * 2**208)/D<br />
<br />
The expected number of hashes we need to calculate to find a block with difficulty D is therefore<br />
D * 2**256 / (0xffff * 2**208)<br />
or just<br />
D * 2**48 / 0xffff<br />
<br />
The difficulty is set such that the previous 2016 blocks would have been found at the rate of one every 10 minutes, so we were calculating (D * 2**48 / 0xffff) hashes in 600 seconds. That means the hash rate of the network was<br />
D * 2**48 / 0xffff / 600<br />
over the previous 2016 blocks. Can be further simplified to<br />
D * 2**32 / 600<br />
without much loss of accuracy.<br />
<br />
At difficulty 1, that is around 7 Mhashes per second.<br />
<br />
At the time of writing, the difficulty is 22012.4941572, which means that over the previous set of 2016 blocks found the average network hash rate was<br />
22012.4941572 * 2**32 / 600 = around 157 Ghashes per second.<br />
<br />
=== How soon might I expect to generate a block? ===<br />
(The [https://www.bitcointalk.org/index.php?topic=1682.0 eternal question].)<br />
<br />
The average time to find a block can be approximated by calculating:<br />
time = difficulty * 2**32 / hashrate<br />
where difficulty is the current difficulty, hashrate is the number of hashes your miner calculates per second, and time is the average in seconds between the blocks you find.<br />
<br />
For example, using Python we calculate the average time to generate a block using a 1Ghash/s mining rig when the difficulty is 20000:<br />
$ python -c "print 20000 * 2**32 / 10**9 / 60 / 60.0"<br />
23.85<br />
and find that it takes just under 24 hours on average.<br />
<br />
* Any one grinding of the hash stands the same chance of "winning" as any other. The numbers game is how many attempts your hardware can make per second.<br />
* You need to know the difficulty (above) and your khash/sec rate (reported by the client).<br />
** [[Mining Hardware Comparison]] has some stats that may help you predict what you could get.<br />
* Visit a calculator or perform the maths yourself,<br />
** http://www.alloscomp.com/bitcoin/calculator.php<br />
* Remember it's just probability! There are no guarantees you will win every N days.<br />

<div>Reward types & explanation:<br />
* '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BTC. Since finding a block requires <current difficulty> shares ''on average'', a PPS method with 0% fee would be 50 BTC divided by <current difficulty>. 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 />
* '''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 />

<div>Reward types & explanation:<br />
* '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BTC. Since finding a block requires <current difficulty> shares ''on average'', a PPS method with 0% fee would be 50 BTC divided by <current difficulty>. 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 />
* '''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 />

<div>'''Pooled mining''' is an approach where multiple generating clients contribute to the generation of a block, and then split the block reward according the contributed processing power. Pooled mining effectively reduces the granularity of the block generation reward, spreading it out more smoothly over time.<br />
<br />
==Introduction==<br />
<br />
With increasing generation difficulty, mining with lower-performance devices can take a very long time before block generation, on average. For example, with a mining speed of 1000 Khps, at a difficulty of 14484 (which was in effect at the end of December, 2010), the average time to generate a block is almost 2 years. <br />
<br />
To provide a more smooth incentive to lower-performance miners, several pooled miners, using different approaches, have been created. With a mining pool, a lot of different people contribute to generating a block, and the reward is then split among them according to their processing contribution. This way, instead of waiting for years to generate 50btc in a block, a smaller miner may get a fraction of a bitcoin on a more regular basis.<br />
<br />
A '''share''' is awarded by the mining pool to the clients who present a valid [[proof of work]] of the same type as the proof of work that is used for creating [[block|blocks]], but of lesser complexity, so that it requires less time on average to generate.<br />
<br />
==Pooled mining approaches==<br />
<br />
The problem with pooled mining is that steps must be taken to prevent cheating by the clients and the server. Currently there are several different approaches used.<br />
<br />
===The slush approach===<br />
<br />
[[Bitcoin Pooled Mining]] (BPM), sometimes referred to as "slush's pool", follows a score-based method. Older shares (from beginning of the round) has lower weight than newer shares, which demotivate cheater from switching between pools inside one round.<br />
<br />
===The puddinpop approach===<br />
<br />
(As of February, 2011, there are no puddinpop pools running.)<br />
<br />
Another approach is the 'metahash' technique, used by puddinpop's [[remote miner]]. Clients generate hashes, and also submit 'metahashes', which are hashes of a large chunk of generated hashes. The server checks that the metahashes are correct (in a round-robin fashion, picking up a metahash from a client that hasn't been checked on the longest), thus preventing clients from simply claiming that they have done work without actually doing the work. The withholding of good blocks by the clients is prevented via the server being in possession of the private key, just as in the previous approach. Rewards are distributed based on the number of metahashes submitted by the clients.<br />
<br />
The generated blocks contain multiple keys in the generation transaction, giving fractional bitcoin amounts to each key, in proportion to their hashing contribution for that block.<br />
<br />
===The BitPenny approach===<br />
<br />
The [[BitPenny]] approach is to offer an instant, flat payout for each share that is solved. The payout is offered from the pool's existing balance and can therefore be withdrawn immediately, without waiting for a block to be solved or confirmed. The possibility of cheating the miners by the pool operator and by timing attacks is thus completely eliminated. <br />
<br />
This method results in the least possible variance for miners while transferring all risk to the pool operator. The resulting possibility of loss for the server is offset by setting the payout lower than the full expected value.<br />
<br />
===Luke-Jr's approach ("[[Eligius]]")===<br />
[[User:Luke-Jr|Luke]] came up with a third approach borrowing strengths from the earlier two.<br />
Like slush's approach, miners submit proofs-of-work to earn shares.<br />
Like puddinpop's approach, the pool pays out immediately via block generation.<br />
When distributing block rewards, it is divided equally among all shares since the last valid block.<br />
Unlike any preexisting pool approach, this means that the shares contributed toward orphaned blocks are recycled into the next block's shares.<br />
In order to spare participating miners from transaction fees, rewards are only paid out if a miner has earned at least 1 BTC. If the amount owed is less, it will be added to the earnings of a later block (which may then total over 1 BTC).<br />
If a miner does not submit a share for over a week, the pool sends any balance remaining, regardless of its size.<br />
<br />
===The Triplemining approach===<br />
The [[Triplemining]] approach is to bring together a medium-sized pool with no fees and clever redistribution of 1% of every found block to allow your share to grow more rapidly than on any other bitcoin mining pool. <br />
<br />
For every found block, we redistribute 1% of the profits to all minipool owners (people with 1 or more friends mining with them). The redistribution is connected to the shares found by your friends, not yours! So if the hash rate of your friends equals or is bigger than yours, your part in the redistribution will be equally bigger.<br />
<br />
===Comparison===<br />
<br />
The cooperative mining approach (slush and Luke-Jr) uses a lot less resources on the pool server, since rather than continuously checking metahashes, all that has to be checked is the validity of submitted shares. The number of shares sent can be adjusted by adjusting the artificial difficulty level.<br />
<br />
Further, the cooperative mining approach allows the clients to use existing miners without any modification, while the puddinpop approach requires the custom pool miner, which are as of now not as efficient on GPU mining as the existing GPU miners.<br />
[[File:Smallgeneration.png|thumb|Puddinpop miners receive coins directly.]]<br />
<br />
Additionally, the puddinpop and Luke-Jr approaches of distributing the earnings by way of including precise sub-cent amounts in the generation transaction for the participants, results in the presence of sub-cent bitcoin amounts in your wallet, which are liable to disappear (as unnecessary fees) later due to a bug in old (before 0.3.21) bitcoin nodes. (E.g., if you have a transaction with 0.052 in your wallet, and you later send .05 to someone, your .002 will disappear.).<br />
<br />
Puddinpop and Luke-Jr miners receive coins directly, which eliminates the delay in receiving earnings that is required on slush-based mining servers. However, earnings sent directly to some services like MyBitcoin and MtGox will not be accounted for.<br />

<div>Reward types & explanation:<br />
* '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BTC. Since finding a block requires <current difficulty> shares ''on average'', a PPS method with 0% fee would be 50 BTC divided by <current difficulty>. 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 />
* '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.<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 />

<div>Shows an estimate of the amount of time, on average, that you will need to do mining at the specified hash rate before you will generate a [[blocks|block]] and earn bitcoins. Additionally, the optimistic (50% probability) and pessimistic (95% probability) estimates are shown as well.<br />
<br />
The hash rate refers to the rate that your mining hardware is performing at as reported by your miner software or from an estimate obtained from the [[mining hardware comparison]] tables.<br />
<br />
The calculation is performed like this:<br />
*Get the current [[target]].<br />
*Divide by 115792089237316195423570985008687907853269984665640564039457584007913129639935, which is the maximum value of a 256-bit number. You now have the probability of a single hash solving a block.<br />
*Take the reciprocal of the probability to get the average number of hashes to solve a block.<br />
*Divide the average number of hashes by your hash/s (''not'' khash/s) to get the average number of seconds required to solve a block.<br />
