Mining pools allow cryptocurrency enthusiasts to pool their resources together to increase mining output. This article discusses how these pools operate.
Mining physical gold, the oldest currency on Earth, involves digging it from beneath the soil. Mining often reveals hidden gold that was not previously available – when successful, an individual or mining company owns their ownership stake of it.
Mining cryptocurrency works similar to finding them digitally with computer programs; the bitcoin protocol stipulates that there will only ever be 21 million bitcoins available for mining.
There may still be bitcoins to mine on the blockchain system, though most have already been mined and are now held by various parties.
Understanding The Mining Process
Mining cryptocurrency involves two functions: creating new cryptocurrency into circulation (like gold discovery) and verifying and recording transactions on a public ledger blockchain network. Mining hardware devices and software programs may be utilized on connected computers to complete this task.
Mining cryptocurrency requires both processing power and electricity, with the first miner to solve a puzzle being awarded with adding another block to the blockchain and reaping any associated rewards – in addition to taking ownership of newly created bitcoin, miners may also earn fees for processing transactions.
The difficulty level of mining depends on how many miners are in operation; when there are more miners working, its difficulty increases, while with less miners operating it decreases. Mining offers attractive returns; more miners means increased competition for a piece of the pie which makes finding new blocks more computationally intensive and requires additional computing power; unfortunately this process may prove impractical and costly for individuals.
Pooling Resources: Let’s Mine Better, Together
Mining pools are groups of miners working collaboratively to increase their chances of locating blocks more rapidly than individually. Mining pools combine computational resources of individual members for greater collective processing power resulting in faster mining outcomes.
One person could cover 100 square metres in one day while searching for gold on one hectare, taking 100 days altogether. By contrast, 100 diggers working together could complete this task in one day; providing they all searched their allocated portions of land equally and divided up any found gold equally among themselves.
One device can be used to form a mining rig consisting of nine separate mining devices that operate at 335 megahashes per second (MH/s), creating an increase in bitcoin find rates while speeding up completion time.
Pooled mining yields greater output and increased chances of success, but at a greater expense to its participants – rewards must be divided among all pool members rather than staying with just one miner who mines solely for reward.
Functions Of A Mining Pool
Mining pools act as facilitators for their members. By managing hashes of members’ work, recording tasks completed by each one, and disbursing rewards in proportion to how much work has been completed and verified, mining pools work to distribute rewards efficiently among them.
Each member miner could also be assessed a fee from the pool.
Work can be assigned to pool members using one of two methods. The traditional one requires them to determine an approximate nonce range that will then be used as the basis for assigning work units; once their tasks have been completed they request another assignment.
Members of a mining pool can select any amount of work without being assigned any by employing a second method, which ensures no two members select similar ranges of values, just as no two gold miners should mine on identical pieces of land.
An increased output can also be achieved using multiple pools in combination.
How Do Mining Pools Share Rewards?
Once a block hash is successfully identified, the pool is rewarded accordingly to their share mechanism. Each member’s computer contributes work to mining pool by contributing shares.
There are two types of shares – accepted and rejected. An accepted share indicates that a pool member’s work is making an important contribution towards finding new cryptocurrencies, so these individuals are rewarded accordingly.
Work that does not contribute to blockchain discovery is unpaid for and therefore unaccepted; even if a member’s computer performs successfully but submits late for a specific block submission deadline, this counts as rejected work.
As much as is hoped for, not all pool members can expect their shares to be accepted. Unfortunately, it’s impossible to ensure that all computations on any given member computer will aid coin discovery, and are always submitted on time, potentially leading to rejected shares.
Reward allocation is determined based on each member’s contribution in finding new coin blocks. Shares don’t hold any monetary value and simply track reward allocation to ensure fairness.
Members are rewarded through various methods, such as:
Pay-per-share mining gives miners an incentive to contribute shares by rewarding them with a portion of the pool’s existing balance for every share they contribute as rewards.
At the conclusion of each mining round, members are awarded according to their share in comparison with total shares held.
SMPPS works similarly to PPS, except its payout is limited by how much the pool has earned.
An ESMPPS mining pool distributes rewards evenly among all miners in equal shares.
Double Geometric Method (DGM) and its variations, including Capped Pay Per Share with Recent Backpay (CPPSRB) and Bitcoin Pooled Mining (BPM), may be permissible.
Before joining any mining pool, miners should evaluate how it divides its payments among members and whether there are any fees charged; typically this ranges between 1%-3% of your funds in fees.
The Bottom Line
Mining has become increasingly popular since high-speed devices compatible with home computers became available, but the chances of making real profits individually through individual mining are becoming increasingly remote. Many individuals prefer joining mining pools that offer high probability returns rather than low probability opportunities for high profits.
