It is risky for pool operators, hence the fee is highest. This is the ultimate low- variance, low-maturity simple method, but has the highest risk for the operator, and hence lower expected returns than other methods and risk of collapse if not managed properly. Variance+risk: Mostly relevant for pools which can adjust variance and operator risk, this is their invariant total. Double geometric method(): A hopping-proof hybrid between the geometric method and PPLNS, including the former and an exponential version of the latter as special cases. The properties of stochastic processes guarantee that the negative balance will eventually become arbitrarily high, inevitably causing the collapse of the pool when it becomes unattractive to mine. Method description Proportional: The block reward is distributed among miners in proportion to the number of shares they submitted in a round bitcoin pools. A high variance PPS variant that pays on the difficulty of work returned to pool rather than the difficulty of work served by pool  PPLNS - Pay Per Last N Shares. The share-variance can be reduced at the cost of increased maturity time, but there is no way to decrease the long-term pool-variance. Like Pay Per Share, but never pays more than the pool earns. Operators of risky methods will require a relatively high fee as compensation, decreasing the expected earnings of participants. Hoppers will take advantage of times of high attractiveness, leaving steady miners to suffer from more than the fair share of unattractive times. Complexity: The level of complexity in describing the method, implementing it and modeling its dynamics. Like SMPPS, but equalizes payments fairly among all those who are owed. If you are interested in alt-coins, try the Alt-coins Mining Pools List: https://bitcointalk. Geometric method (): This is a hopping-proof method based on a more accurate implementation of the principles set forth by slushs method. Variance+risk+maturity: Mostly relevant for pools which can adjust variance, risk and maturity time, this is their invariant total bitcoin pools. Using a method with high pool-variance does no harm to large pools.
RSMPPS - Recent Shared Maximum Pay Per Share. Calculate a standard transaction fee within a certain period and distribute it to miners according to their hash power contributions in the pool. PPLNSG - Pay Per Last N Groups (or shifts). This is the worst reward system and must not be used. slushs method (): Each share is rewarded with a score depending on when it was submitted (an exponential function of time), and block rewards are distributed among miners in the round in proportion to their score. Maturity time, variance and operator risk are adjustable, with a low total invariant. Merge Mining: Options: Yes / No Thank you to Meni Rosenfeld, whose Pool summary appears in the post below the current pools list. The total reward for a share converges to a steady-state ratio of the maximum long- term payment possible per share after losses. It is historically the first method developed specifically to combat pool-hopping, though it is incomplete and some hopping is still possible. 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. ESMPPS (): A refinement of SMPPS, where the least paid shares are prioritized. If this steady-state is accepted as the due expected reward, this keeps maturity time in check and prevents debt, measured up to the steady-state level, from piling up. The variance for intermittent miners will be especially high, though. (at slush s pool C=300 seconds, and every hour scores are normalized) SMPPS - Shared Maximum Pay Per Share. Contrary to a popular myth, the method is perfectly usable by intermittent miners and their long-term average returns wont be affected. 5 BTC for now) but also some of the transaction fees. If there are any mistakes, pool ops please reply in the thread.
All implementations cannot be hopped using traditional methods. This makes later shares worth much more than earlier shares, thus the miner s score quickly diminishes when they stop mining on the pool. Instability: This is the probability of the pools collapse, and the severity of the event.DigiByte.. For a more comprehensive discussion of these methods, see . Each submitted share is worth more in the function of time t since start of current round. Rewards are calculated proportionally to scores (and not to shares). I ll endeavour to add more pools as I can. The pool may survive this if the participants are loyal. Operator risk: This is the risk the operator is taking in absorbing some of the pools variance. Our expert team is ready to develop a custom-built mining pool for you. Each submitted share is worth certain amoutripnt of BC. Share-variance: This is the variance (statistical deviation between the expected re- ward for a share and the actual reward) caused by the miner being too small or inter- mittent. NOTE FOR BITCOIN POOL OPERATORS: If your pool doesn t appear here please post the pool s statistics in the following format: Quote Proxy: Are you a proxy pool. Since finding a block requires
