Comparison of mining pools

UM:

Reward types & explanation:
* '''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.
* '''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]
* '''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]
* '''CPPSRB''' - Capped Pay Per Share with Recent Backpay.
* '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.
* '''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.
* '''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)

UM:

Reward types & explanation:
* '''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.
* '''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]
* '''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]
* '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.
* '''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.
* '''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)

Comparison of mining pools

UM:

Reward types & explanation:
* '''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.
* '''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]
* '''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]
* '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.
* '''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.
* '''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)

UM: Created page with "This pool pays out using a proportional share reward system (your shares / total shares for the round) = % share of the rewards. The service was first available on July 22nd,..."

This pool pays out using a proportional share reward system (your shares / total shares for the round) = % share of the rewards.

The service was first available on July 22nd, 2011.

==Features==

* TXT/SMS idle miners notification (US numbers only)
* Built on redundant clustered systems, all servers are in a cluster, even the firewall and load balancer.
* Offers managed rig OS (Linux) that features an iPhone/Mobile internet page. You can update and check on your rig from your cell phone. Enables easy overclocking and monitors itself for heat problems.

==Reward distribution==

* Proportional: 3% fee.

Comparison of mining pools

UM:

Reward types & explanation:
* '''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.
* '''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]
* '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.
* '''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.
* '''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)
