How Do Cryptocurrency Mining Pools Work, Investopedia

A cryptocurrency enthusiast willing to reap profits through the standard mining process either goes solo using his/hier own mining devices, or joins a mining pool where his/hier mining resources are clubbed with those of other pool miners to improve the mining output with enhanced processing. This article discusses how mining pools work.

The world’s oldest currency, physical gold, is dug out of the earth through the process of gold mining. It detects hidden gold that is not yet available. Successful mining permits the individual digger or the mining company to own the gold.

Cryptocurrency mining works similarly, spil virtual coins can be discovered digitally using rekentuig programs. The bitcoin system has set a limit of total 21 million bitcoins.

All thesis bitcoins are lounging within the blockchain system. Most are already dug out or “mined,” and possessed by different participants, while the surplus are ter the process of being mined and will eventually become available. (See more: Only 20 Procent Of Total Bitcoins Remain To Be Mined.)

Understanding the Mining Process

Cryptocurrency mining involves two functions – releasing fresh cryptocurrency into the system (similar to gold discovery), and verifying and adding transactions to the blockchain public ledger. It is performed using an internet-connected pc which is often tooled with special mining hardware devices and software programs to control and manage the mining process.

Crypto mining is a calculation-intensive, puzzle-solving-like computation process that requires high processing power along with high electric current consumption. The miner who very first solves the puzzle gets to place the next block on the blockchain and keuze the prizes. Prizes include the miner becoming the holder of the freshly released bitcoin, or getting fees linked to the transactions performed te the block. (For more, see How Does Bitcoin Mining Work?)

The cryptocurrency discovery process is configured ter such a way that if more miners are working, the difficulty level goes up, while a decline te the number of miners eases the difficulty level. The prizes make mining a lucrative activity for monetary gains. Spil more miners attempt to grab a lump of the pie, finding fresh blocks gets computationally more difficult, requiring more computing power. This is often impractical and too expensive for individual miners.

Pooling Resources: Let’s Mine Better, Together!

Come in the mining pool, which is a collection/group of miners working together to increase their chances of finding a block at the group level, compared to that at the individual level. Through such pools, miners combine their individual computational resources with those of the other members which enhances their snaak processing power, and helps to achieve the desired output quicker.

To draw an analogy, a gold digger having a capacity to dig 100 square meters of land ter one day will take 100 days to explore one hectare of land for gold. Combining 100 gold diggers can finish the job te just 1 day. The discovered gold can be split among all 100 diggers evenly, assuming all have waterput ter equal effort to explore their assigned portions of land.

Similarly, one can combine nine mining devices, each generating mining power of 335 megahashes vanaf 2nd (MH/s), to generate a combined output of around Trio gigahashes. The output is swifter and has a better chance to detect bitcoins.

However, this pooled work with better output and higher chances, comes at a cost. The prize earned through combined mining is split among the various pool members, spil compared to foot ownership on the prize earned through individual mining.

Functions of a Mining Pool

A mining pool essentially works spil a coordinator for the pool members. The functions involve managing the pool members’ hashes, looking for prizes through pooled efforts of available processing power, recording work performed by each pool member, and assigning prize shares to each pool member ter proportion to the work performed after suitable verification.

The pool may also charge a toverfee from each member miner.

Work to each pool member can be assigned te two ways. The traditional method involves assigning members a work unit comprised of a particular range of nonce, the number that blockchain miners are computing for. Once the pool member completes the work on the assigned range, he places a request for a fresh work unit to be assigned.

A 2nd mining method permits pool members the liberty to pick and choose spil much work spil they like without any assignment coming from the pool. The methodology ensures that no two members take the same range, just like no two gold diggers should explore the same chunk of land.

There can also be a pool of pools, to further enhance output.

How Do Mining Pools Share Prizes?

Successful identification of the block hash leads to prize for the pool, which is then collective based on the pool shares mechanism. Shares describe how much work a particular member’s pc is contributing to the mining pool.

There are two kinds of shares – accepted and rejected. Accepted shares indicate that work done by a pool member is contributing substantially towards discovering fresh cryptocoins, and thesis get rewarded.

Rejected shares represent work that does not contribute to a blockchain discovery, and hence are not paid for. Even if a member’s rekentuig performs work successfully but submits it late for that particular block, it constitutes rejected work.

A pool member ideally wants that all his shares get accepted. However, rejected shares are unpreventable spil it is unlikely that all the computations on a member’s rekentuig will be useful ter coin discovery, and will always be submitted on time.

Pool members are rewarded based on their accepted shares that helped te finding a fresh coin block. A share has no actual value, and it simply acts spil an accounting method to keep the prize distribution fair.

Based on the accepted shares, members get rewarded using different methods, which include the following:

  • Pay-per share (PPS): Permits instant payout solely based on accepted shares contributed by the pool member, who are permitted to withdraw their earnings instantly from the pool’s existing balance.
  • Proportional (PROP): At the end of a mining round, a prize which is proportional to the number of the member’s shares with respect to total shares ter the pool, is suggested.
  • Collective Maximum Pay Vanaf Share (SMPPS): A method similar to PPS but thresholds the payout to the maximum that the pool has earned.
  • Equalized Collective Maximum Pay Vanaf Share (ESMPPS): A method similar to SMPPS, but distributes payments identically among all miners te the bitcoin mining pool.

Other variations include Dual Geometric Method (DGM), Latest Collective Maximum Pay Vanaf Share (RSMPPS), Capped Pay Vanaf Share with Latest Backpay (CPPSRB), and Bitcoin Pooled Mining (BPM).

Before determining to join a particular pool, miners should pay attention to how each pool shares its payments among members and what fees, if any, it charges. Typically, pools may charge inbetween 1% and 3% spil pool fees.

The Bottom Line

With mining becoming enhancing popular aided by high-speed devices compatible with huis computers, the chances of realistically profiting from individual mining are diminishing. Most individuals opt to join a mining pool which permits them high-probability limited profits, instead of low-probability high profits.
