A mining pool is a group of miners who combine their computational power to find blocks more frequently.

As network competition increases, finding a block alone becomes more difficult and takes more time.
For this reason, mining pools were created: blocks are found more often, but the reward is shared among all participants.
This allows miners to earn smaller but more consistent rewards instead of large but very rare payouts.

A share is a partial proof of work that a miner submits to the pool.
It is used to show how much work the miner is contributing toward finding a block.

Each share has a certain difficulty, and when a miner submits a share, it means they have found a valid solution for that difficulty.
In many pools, rewards are calculated based on the number of shares submitted.

• SOLO(solo mining): If you find a block, you keep 100% of the reward.


• PROP(Proportional): When the pool finds a block, the reward is divided based on each miner’s contribution during the round(a round is the time between two blocks).


• PPLNS(Pay Per Last N Shares): Similar to PROP, but rewards are based only on the last N shares submitted; this favors miners who stay connected longer and penalizes those who frequently join and leave.


• PPS(Pay Per Share): Each submitted share is paid immediately based on its difficulty; earnings are stable and independent of whether the pool finds a block.


• FPPS(Full Pay Per Share): Similar to PPS, but also includes an estimate of the transaction fees from the block, in addition to the base reward.

Mining pools charge a fee for their service, expressed as a percentage.
The fee can be applied either to the block reward or to share-based payouts, depending on the payment method.

• SOLO: 0.5% - 1%
• PROP: 1%-2%
• PPLNS: 1%-2%
• PPS: 1%-2%
• FPPS: 2%-4%

There are also anonymous pools, which do not collect personal data.
The only required information is the wallet address for payouts, providing greater privacy.
