Pay Per Share
Pay Per Share pays miners a fixed amount for each valid share submitted to a mining pool.
Definition
Pay Per Share, often shortened to PPS, is a mining pool payout method where miners receive a fixed payment for every valid share. A share proves that a miner contributed useful work, even when that work did not find a block. PPS turns uncertain block rewards into steadier mining income.
How It Works
In a mining pool, many miners combine hash rate so they can find blocks more often than they would alone. Each miner receives work, often through the Stratum Protocol, and submits shares when machines find hashes that meet the pool’s easier target.
With PPS, the pool estimates each share’s expected value from network difficulty, block subsidy, transaction fees, and the coin being mined. When a miner submits a valid share, the pool credits that miner immediately at the set PPS rate. The miner does not wait for the pool to find a block.
This makes PPS different from proportional or score-based systems, where miners are paid only after the pool finds a block. In PPS, the pool takes on bad-luck risk. If it finds fewer blocks than expected, it still owes miners for accepted shares. To cover that risk, PPS pools usually charge higher fees.
Why It Matters
PPS matters because it gives miners predictable revenue. A miner can estimate earnings from hash rate, compare pool offers, and plan electricity or hosting costs with less variance. This is useful for smaller miners who do not want income to swing sharply with pool luck.
The tradeoff is cost. A PPS pool’s higher fee can reduce long-term earnings compared with lower-fee payout methods, especially when the pool performs close to statistical expectations. Miners choosing PPS are usually paying for stability: fewer surprises, simpler accounting, and less exposure to pool luck.
For mining businesses, PPS also affects cash flow. Since revenue is credited per accepted share, operators can connect machine performance, Hash Rate, and Mining Profitability more directly. Miners should still check pool reputation, fees, payout thresholds, and how transaction fees are handled.
