In the context of cryptocurrency mining, a mining pool is the pooling of resources by miners, who share their processing power over a network, to split the reward equally, according to the amount of work they contributed to the probability of finding a block.[1] A "share" is awarded to members of the mining pool who present a valid partial proof-of-work. Mining in pools began when the difficulty for mining increased to the point where it could take centuries for slower miners to generate a block. The solution to this problem was for miners to pool their resources so they could generate blocks more quickly and therefore receive a portion of the block reward on a consistent basis, rather than randomly once every few years.[2][3]

Pooled mining (BPM), also known as "slush's system", due to its 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 recent shares. A new round starts the moment the pool solves a block and miners are rewarded Proportional to the shares submitted.[6] This reduces the ability to cheat the mining pool system by switching pools during a round, to maximize profit.
Usually, the blocks in the cryptocurrency network contain transactions. Transaction fees are paid to the miner (mining pool). Different mining pools could share these fees between their miners or not. Pay-per-last-N-shares (PPLNS), Pay-Per-Share Plus (PPS+) or Full Pay-Per-Share (FPPS) are the most fair methods where the payouts from the pool include not only the block subsidy but also the transaction fees.[citation needed]
Multipools switch between different altcoins and constantly calculate which coin is at that moment the most profitable to mine. Two key factors are involved in 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 in the mainstream (for example bitcoin). 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 in the intended currency than by mining that currency alone. This method also increases demand on the intended coin, which has the side effect of increasing or stabilizing the value of the intended coin.[9]
Similar to other mining technologies, the PoC, PoC+, PoS Proof of Space method allows the computing to be performed beforehand and all answers are stored on a miners hard drive, the heavy energy consumption for PoC is not required like it is for PoW mining and therefore PoC is almost always a more environmentally friendly blockchain choice. When mining happens the miner simply "looks" through the pre-stored answers and submits the best one found to the network, with minimal energy used to read the hard drives. Due to the low hardware specification requirements of the PoC mining process, this type of mining can be conducted on a regular PC still being used for other day-to-day tasks. The first PoC blockchain was brought online in 2014 and is known as Signum today, with other PoC chains coming out much later, examples: Chia, Flax, and BitcoinHD. The network difficulty, as well as other network and mining status information, can be viewed on any of the public mining pool dashboards, example: Mining Pool Dashboard A list of current PoC, PoS, PoC+ type mining pools are also tracked by some third party "Mining Pool Stats" pages, an example of one is Mining Pool Stats.
Bitcoin mining is so-called because it resembles the mining of other commodities:it requires exertion and it slowly makes new units available to anybody who wishes to take part. An important difference is that the supply does not depend on the amount of mining. In general changing total miner hashpower does not change how many bitcoins are created over the long term.
Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.
Early Bitcoin client versions allowed users to use their CPUs to mine. The advent of GPU mining made CPU mining financially unwise as the hashrate of the network grew to such a degree that the amount of bitcoins produced by CPU mining became lower than the cost of power to operate a CPU. The option was therefore removed from the core Bitcoin client's user interface.
As more and more miners competed for the limited supply of blocks, individuals found that they were working for months without finding a block and receiving any reward for their mining efforts. This made mining something of a gamble. To address the variance in their income miners started organizing themselves into pools so that they could share rewards more evenly. See Pooled mining and Comparison of mining pools.
The vast majority of mining power is grouped together in mining pools to reduce variance in miner income. Independent miners may have to work for several years to mine a single block of transactions and receive payment. In a mining pool, all participating miners get paid every time any participant generates a block. This payment is proportionate to the amount of work an individual miner contributed to the pool.[62][better source needed]
One environmental impact of Bitcoin is that it worsens climate change.[317] This is because bitcoins are made using electricity partially generated by gas and coal-fired power plants. When burned, coal and natural gas emit greenhouse gases, which heat the Earth and change the climate.[318] As of 2022[update], such bitcoin mining is estimated to be responsible for 0.1% of world greenhouse gas emissions.[319] A second environmental impact is the air pollution caused by coal-fired electricity generation, and a third is the e-waste due to the short life expectancy of bitcoin mining equipment.[317]
The following pools are known or strongly suspected to be mining on top of blocks before fully validating them with Bitcoin Core 0.9.5 or later. Miners doing this have already lost over $50,000 USD during the 4 July 2015 fork and have created a situation where small numbers of confirmations are much less useful than they normally are.
It takes an average of 10 minutes for the mining network to validate a block and create the reward. The Bitcoin reward is 6.25 BTC per block. This works out to be about 100 seconds for 1 BTC to be mined."}},"@type": "Question","name": "Is Bitcoin a Good Investment?","acceptedAnswer": "@type": "Answer","text": "Bitcoin has a short investing history filled with very volatile prices.
