Bitcoin mining pools are a way for Bitcoin miners to pool their resources together and share their hashing power while splitting the prize identically according to the amount of shares they contributed to solving a block.
A “share” is awarded to members of the Bitcoin mining pool who present a valid proof of work that their Bitcoin miner solved. Bitcoin mining ter pools began when the difficulty for mining enlargened 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 quicker and therefore receive a portion of the Bitcoin block prize on a consistent fundament, rather than randomly once every few years.
If you solo-mine, meaning you do not mine with a Bitcoin mining pool, then you will need to ensure that you are ter overeenstemming with the Bitcoin network. The best way is to use the official BitCore client.
If you participate te a Bitcoin mining pool then you will want to ensure that they are engaging te behavior that is te agreement with your philosophy towards Bitcoin.
For example, some rogue developers have threatened to release software that could hard-fork the network which would likely result te tremendous financial harm.
Therefore, it is your duty to make sure that any Bitcoin mining power you rechtstreeks to a mining pool does not attempt to enforce network overeenstemming rules you disagree with.
When segwit is activated, you will want to be able to mine and relay segwit-style blocks. The following mining software has bot upgraded to support segwit.
Please note that software that supports the GetBlockTemplate (GBT) RPC voorwaarde be upgraded to support the BIP9 and BIP145 switches to GBT. All the programs linked above that support GBT have bot upgraded.
Segwit is already activated and enforced on testnet, so you may find it useful to test your infrastructure upgrade by mining with some petite amount of hashrate on testnet. Alternatively, Bitcoin Core 0.13.1’s regression test mode (regtest) also supports segwit by default.
Bitcoin Mining Pools
There are many good Bitcoin mining pools to choose from. Albeit it’s tempting to pick the most popular one, it’s better for the health of the network to mine with smaller pools so spil to avoid potentially harmful concentration of hashing power.
The hash rate distribution is best when split among more Bitcoin mining pools.

Bitcoin Mining Pool Options
For a fully decentralized pool, wij very recommend p2pool.
The following pools are believed to be presently fully validating blocks with Bitcoin Core 0.11 or straks:
BTCC: BTCC is a Bitcoin exchange, wallet, and mining pool located ter China. Its mining pool presently controls around 15% of the network hash rate.
Slush Pool: Slush Pool is run by Satoshi Labs, a Bitcoin company based te the Czech Republic. Slush Pool wasgoed the very first mining pool and maintains around 7% of the network hash rate.
Antpool: [WARNING] – Bitmain operates Antpool and some consider them to be a malicious actor ter the Bitcoin ecosystem because of the AntBleed scandal where they were intentionally including malware within mining equipment they sell. Ter a corporate communication, Bitmain claimed this wasgoed a feature and not a bug. This malware would enable Bitmain to remotely shut down equipment of customers or competitors thus enlargening their own profitability. Additionally, such behavior could pose a risk to the entire Bitcoin network.
Eligius: Eligius wasgoed one of the very first Bitcoin mining pools and wasgoed founded by Luke Dashjr, a Bitcoin Core developer. Today, the pool controls just under 1% of the network hash rate.
BitMinter: BitMinter, once one of the largest Bitcoin mining pools, now controls less than 1% of the network hash rate.
Kano CKPool: Kano CKPool wasgoed founded te 2014 and presently has around 3% of the network hash rate under its control.
F2Pool: F2Pool is the 2nd largest Bitcoin mining pool, with around 25% of the network hash rate. Its user interface is te Chinese, making it difficult for English speakers to join.
BW Pool: BW Pool controls around 7% of the network hash rate. Like F2Pool, its user interface is ter Chinese, making it difficult for English speakers to join.
Bitfury: Albeit seen publically ter block explorers and hash rate charts, BitFury is a private mining pool and cannot be joined.
Bitcoin Mining Pool Payment Methods
Calculating your share of the bitcoins mined can be ingewikkeld. Ter an ongoing effort to come up with the fairest method and prevent gaming of the system, many calculation schemes have bot invented. The two most popular types are PPS and DGM. PPS, or ‘pay vanaf share’ shifts the risk to the mining pool while they ensure payment for every share you contribute.
PPS payment schemes require a very large reserve of Ten,000 BTC ter order to ensure they have the means of suffering a streak of bad luck. For this reason, most Bitcoin mining pools no longer support it.
One of the few remaining PPS pools is EclipseMC. DGM is a popular payment scheme because it offers a nice balance inbetween brief round and long round blocks. However, end users vereiste wait for utter round confirmations long after the blocks are processed.
PPS: The Pay-per-Share (PPS) treatment offers an instant, ensured payout for each share that is solved by a miner. Miners are paid out from the pools existing balance and can withdraw their payout instantaneously. This proefje permits for the least possible variance ter payment for miners while also transferring much of the risk to the pool’s technicus.
PROP: The Proportional treatment offers a proportional distribution of the prize when a block is found amongst all workers, based off of the number of shares they have each found.
PPLNS: The Pay Vanaf Last N Shares (PPLN) treatment is similar to the proportional method, but instead of counting the number of shares te the round, it instead looks at the last N shares, no matter the boundaries of the round.
DGM: The Dual Geometric Method (DGM) is a hybrid treatment that enables the technicus to absorb some of the risk. The technicus receives a portion of payouts during brief rounds and comebacks it during longer rounds to normalize payments.
SMPPS: The Collective Maximum Pay Vanaf Share (SMPPS) uses a similar treatment to PPS but never pays more than the Bitcoin mining pool has earned.
ESMPPS: The Equalized Collective Maximum Pay Vanaf Share (ESMPPS) is similar to SMPPS, but distributes payments identically among all miners te the Bitcoin mining pool.
RSMPPS: The Latest Collective Maximum Pay Vanaf Share (RSMPPS) is also similar to SMPPS, but the system prioritizes the most latest Bitcoin miners very first.
CPPSRB: The Capped Pay Vanaf Share with Latest Backpay uses a Maximum Pay Vanaf Share (MPPS) prize system that will pay Bitcoin miners spil much spil possible using the income from finding blocks, but will never go bankrupt.
BPM: Bitcoin Pooled mining (BPM), also known spil “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.
POT: The Pay on Target (POT) treatment is a high variance PPS that pays out ter accordance with the difficulty of work returned to the pool by a miner, rather than the difficulty of work done by the pool itself.
SCORE: The SCORE based treatment uses a system whereby a proportional prize is distributed and weighed by the time the work wasgoed submitted. This process makes zometeen shares worth more than earlier shares and scored by time, thus prizes are calculated ter proportion to the scores and not shares submitted.
ELIGIUS: Eligius wasgoed designed by Luke Jr., creator of BFGMiner, to incorporate the strengths of PPS and BPM pools, spil miners submit proofs-of-work to earn shares and the pool pays out instantaneously. When the block prizes are distributed, they are divided identically among all shares since the last valid block and the shares contributed to stale blocks are cycled into the next block’s shares. Prizes are only paid out if a miner earns at least. 67108864 and if the amount owed is less than that it will be spinned overheen to the next block until the limit is achieved. However, if a Bitcoin miner does not submit a share for overheen a period of a week, then the pool will send any remaining balance, regardless of its size.
Triplemining: Triplemining brings together medium-sized pools with no fees and redistributes 1% of every block found, which permits your share to grow swifter than any other Bitcoin mining pool treatment. The administrators of thesis Bitcoin mining pools use some of the Bitcoins generated when a block is found to add to a jackpot that is triggered and paid out to the member of the pool who found the block. Te this way, everyone te the pool has a better chance to make extra Bitcoins, regardless of their processing power.

An application-specific integrated circuit (abbreviated spil ASIC) is an integrated circuit (IC) customized for a particular use, rather than intended for general-purpose use. Te Bitcoin mining hardware, ASICs were the next step of development after CPUs, GPUs and FPGAs. Capable of lightly outperforming the aforementioned platforms for Bitcoin mining te both speed and efficiency, all Bitcoin mining hardware that is practical ter use will make use of one or more Bitcoin (SHA256d) ASICs.
Note that Bitcoin ASIC chips generally can only be used for Bitcoin mining. While there are zonderling exceptions – for example chips that mine both Bitcoin and Litecoin – this is often because the chip package effectively has two ASICs: one for Bitcoin and one for Litecoin.
The ASIC chip of choice determines, te large part, the cost and efficiency of a given miner, spil ASIC development and manufacture are very expensive processes, and the ASIC chips themselves are often the components that require the most power on a Bitcoin miner.
While there are many Bitcoin mining hardware manufacturers, some of thesis should be seen spil systems integrators – using the ASIC chips manufactured by other parties, and combining them with other electronic components on a houtvezelplaat to form the Bitcoin mining hardware.
Bitcoin ASIC development rhythm
The rhythm at which Bitcoin ASICs have bot developed, for a previously non-existent market, has seen some academic rente. One paper titled “Bitcoin and The Age of Bespoke Silicon” notes:
The Bitcoin and Cryptocurrency Technologies online course by Princeton University notes:
A timeline overview for CoinTerra’s Goldstrike 1 chip also shows this spil 8 months inbetween founding the company and shipping a product.
Bitcoin ASIC specifications
A Bitcoin ASIC’s specification could be seen spil having a certain hash rate (e.g. Gh/s) at a certain efficiency (e.g. J/Gh). While cost is another factor, this is often a relatively stationary factor spil the ondergrens cost of a chip will be determined by the fabrication process, while the maximum cost will be determined by market coerces, which are outside of post-fabrication technological control.
When reading the specifications for ASICs on this pagina is that they should be interpreted spil being indicative, rather than authoritative. Many of the figures will have come from the manufacturers, who will present their technology te the best light – be that high hash rates that ter practice may not be very efficient and require extra cooling, or very high efficiency at a cost of hash rate and taking a chance being slow ter the wedloop against difficulty adjustments.
Complicating the matter further is that Bitcoin ASICs can often be made to cater to both finishes of the spectrum by varying the clock frequency and/or the power provided to the chip (often via a regulated voltage supply). Spil such, chips can not be directly compared.
Comparing Bitcoin ASICs
Two proposals have bot made te the past for attempts at comparing ASICs – Gh/mm² and η-factor.
Gh/mm² is a plain measure of the number of Gigahashes vanaf 2nd of the chip, divided by its diegene area (area of the the actual silicon). This measure however does not take into account the knot size which affects how many logical cells can getraind te a given area.
Spil a result, η-factor wasgoed suggested at the BitcoinTalk Forums which attempts to take the knot size into account, by multiplying the Gh/mm² value by the half the knot size, three times.
Albeit the merit of thesis approaches can be debated, ultimately thesis figures are not spil significant spil the ones that detail what is required to make an ASIC work. If an ASIC requires very stable power supply, then the power supply circuitry on a houtvezelplaat may be more expensive than for another ASIC. If the ASIC has a ingewikkeld communications protocol, extra relatively expensive components may be required. If an ASIC’s diegene is large, fewer (rectangular slices) can be obtained from a (circular) wafer, defects affect its vormgeving dispropotionately, and cooling solutions are generally more ingewikkeld compared to smaller diegene chips which te turn have other overhead. Chips with a BGA vormgeving are less ordinary to integrate than a QFN, requiring more expensive (inspection and testing) equipment.
Nevertheless, for historic purposes they are included te listings here where sufficient information is available.
Number of cores
One other oft-mentioned number statistic for an ASIC chip is the number of cores or hashing engines that are on the chip. While this number is directly related to voorstelling, it is not necessarily a comparitive relation.
Bitmain Technologies’ BM1382 calculates 63 hashes vanaf clock cycle (Hz), while their more efficient BM1384 calculates 55 hashes vanaf clock cycle. Similarly, while thesis hashes vanaf clock cycle are spot-on for the claims regarding the number of cores, BitFury’s BF756C55 is claimed to have 756 cores, but yields around 11.6 hashes vanaf clock cycle. This is because the reference to cores sometimes mean different things, and certain designs result ter less straightforward calculation 
Nevertheless, when a designer makes claims regarding hash rates at certain clock frequencies, one can determine if A. there is a straightforward calculation and B. if the designer is being imprecise (rounding values) or even intentionally dishonest, spil the ratio inbetween clock cycles and hash rate should remain the same.
