Mining Pools Rewards | How They Work

Mining pools are an essential component of the cryptocurrency mining ecosystem, enabling miners to combine their computational power and increase their chances of earning rewards. Cryptocurrency mining, particularly for Proof of Work (PoW) cryptocurrencies like Bitcoin, requires significant computational resources. Solo mining can be challenging due to the high level of competition and the randomness of block discovery. Mining pools address these challenges by bringing together multiple miners to work as a team towards a common goal.

Mining pool rewards are an integral part of the mining process. The way rewards are distributed among miners can vary based on the chosen reward system employed by the pool. Let’s explore the different types of reward systems and their impact on miners’ earnings:

Exploring Different Mining Pool Reward Systems

Pay-per-Share (PPS):

Pay-per-Share is a popular reward system used by mining pools. Under this system, miners receive a fixed payment for each share they contribute, regardless of whether the pool successfully mines a block or not. This approach provides miners with a stable income stream, as they are guaranteed a payout for their mining efforts. However, the fixed payment is generally lower than the potential earnings from successfully mining a block.


Proportional reward systems distribute rewards to miners based on the number of shares they submit relative to the total shares of the pool. When a block is mined, the rewards are divided among the miners based on their proportional contribution. Miners with higher hashrates receive more significant rewards, reflecting their greater computational power. This system offers a fair distribution of rewards but carries the risk of higher variance, as miners may have to wait for their efforts to result in a successfully mined block.

Pay-per-Last-N-Shares (PPLNS):

Pay-per-Last-N-Shares is another common reward system used by mining pools. With PPLNS, rewards are distributed to miners based on the number of shares they contributed over a specific period. The timeframe considered may vary between pools. This system encourages continuous participation, as miners who consistently contribute shares have a higher chance of earning rewards. However, newcomers or intermittent miners may face challenges in receiving rewards immediately, as their shares need to meet the “last N” requirement.

Factors Affecting Pool Reward

Hashrate: The computational power (hashrate) contributed by a miner directly influences their share of the rewards. Miners with higher hashrates have a greater probability of contributing more shares and, consequently, earning more rewards. b. Pool Luck: Mining is probabilistic, and pool luck refers to the likelihood of a pool successfully mining a block. In periods of good luck, where blocks are mined more frequently, miners receive rewards more frequently. Conversely, during periods of bad luck, rewards may be less frequent. c. Pool Fees: Mining pools typically charge a fee for their services, which is deducted from the miners’ rewards. It is essential to consider the fee structure when evaluating potential mining pools, as higher fees can reduce overall profitability.

Bottom line

Mining pool rewards play a crucial role in determining the earnings of cryptocurrency miners. The choice of a reward system can impact the stability and profitability of mining operations. Understanding the various reward systems, such as Pay-per-Share, Proportional, and Pay-per-Last-N-Shares, helps miners make informed decisions when selecting a mining pool. By considering factors like hashrate, pool luck, and pool fees, miners can optimize their mining strategies and maximize their potential earnings in the collaborative environment of mining pools.
