Mining pool

Te the setting of cryptocurrency mining, a mining pool is the pooling of resources by miners, who share their processing power overheen a network, to split the prize identically, according to the amount of work they contributed to the probability of finding a block. A “share” is awarded to members of the mining pool who present a valid partial proof-of-work. Mining te pools began when the difficulty for mining enhanced to the point where it could take years for slower miners to generate a block. The solution to this problem wasgoed for miners to pool their resources so they could generate blocks more quickly and therefore receive a portion of the block prize on a consistent fundament, rather than randomly once every few years.

Pay-per-Share Edit

The Pay-per-Share (PPS) treatment offers an instant, assured payout to a miner for his contribution to the probability that the pool finds a block. Miners are paid out from the pool’s existing balance and can withdraw their payout instantaneously. This proefje permits for the least possible variance te payment for miners while also transferring much of the risk to the pool’s technicus.

Each share costs exactly the expected value of each hash attempt R = B p <\displaystyle R=B\cdot p>.

Proportional Edit

Bitcoin Pooled mining Edit

Bitcoin Pooled mining (BPM), also known spil “slush’s system”, due to its very first use on a pool called “slush’s pool’, uses a system where older shares from the beginning of a block round are given less weight than more latest shares. This reduces the capability to cheat the mining pool system by switching pools during a round, to maximise profit.

Pay-per-last-N-shares Edit

PPLNS method is similar to Proportional, but the miner’s prize is calculated on a ondergrond of N last shares, instead of all shares for the last round. Therefore, if the round wasgoed brief enough all miners get more profit, and vice versa.

Geometric method Edit

GM wasgoed invented by Meni Rosenfeld. [Five] It is based on the same “score” idea, spil Slush’s method: the score granted for every fresh share, relatively to already existing score and the score of future shares, is always the same, thus there is no advantage to mining early or late te the round.

The method goes spil goes after:

Dual Geometric method Edit

Multipools switch inbetween different altcoins and permanently calculate which coin is at that ogenblik the most profitable to mine. Two key factors are involved te the algorithm that calculates profitability, the block time and the price on the exchanges. To avoid the need for many different wallets for all possible minable coins, multipools may automatically exchange the mined coin to a coin that is accepted te the mainstream (for example bitcoin). [6] Using this method, because the most profitable coins are being mined and then sold for the intended coin, it is possible to receive more coins te the intended currency than by mining that currency alone. This method also increases request on the intended coin, which has the side effect of enlargening or stabilizing the value of the intended coin. [ citation needed ]
