Mining Payout Methods
Mining payout methods divide pool rewards, manage risk, and affect cash flow for cryptocurrency miners.
Definition
Mining payout methods are the rules a mining pool uses to calculate and distribute rewards to miners. They define how submitted work is counted, when a miner gets paid, and who carries the risk when the pool has good or bad luck finding blocks. The main methods — PPS, PPLNS, FPPS, proportional, and solo — differ in variance, fee structure, and how they split the uncertainty of block discovery.
How It Works
In pool mining, many miners combine hash rate so they can find blocks more regularly than they could alone. Each miner sends small proofs of work called shares to the pool. A share is not usually a real block, but it proves useful hashing power. The pool records accepted shares and applies a payout formula.
Pay Per Share (PPS)
With Pay Per Share, the pool pays a fixed amount for every valid share, regardless of whether the pool finds a block. The rate is calculated from the current Block Reward and Mining Difficulty. PPS gives miners the most predictable income, but pools charge higher fees — typically 3% to 5% — to cover the variance they absorb. If the pool runs cold, the operator still pays out.
Pay Per Last N Shares (PPLNS)
With PPLNS, miners are paid only when the pool finds a block. The reward is split among miners who submitted shares during a recent window of N shares. This window means a miner who switches pools mid-round can lose partial work. PPLNS fees are lower, often 0.5% to 2%, but income is uneven because it depends on how often the pool finds blocks.
Full Pay Per Share (FPPS)
FPPS extends PPS by also estimating transaction fees and including them in the per-share payout. This gives miners a share of both the block subsidy and transaction fee revenue without waiting for a block. FPPS fees are moderate, typically 1% to 4%. The pool still absorbs luck risk but passes through more of the block’s total value to miners.
Proportional
In a proportional system, the full reward from each found block is split among miners based on the shares they submitted during that round. A round starts when the pool begins work on a block and ends when it finds one. Proportional payouts are simple, but miners can game the system by joining only during rounds that have already consumed many shares — a practice called pool hopping.
Score-Based
Score-based methods assign a decay weight to older shares in a round. Recent shares count for more than older ones, which reduces the advantage of hopping between pools. This creates a payout curve somewhere between proportional and PPLNS.
Solo Mining
In solo mining, a miner does not pool work at all. The miner keeps 100% of any block found but absorbs full variance. Solo payouts have no fee but are extremely irregular — a small miner could go months without finding a block. Solo is only practical for large operators or those comfortable with long dry spells.
Why It Matters
Payout methods shape a miner’s cash flow, risk, and expected earnings after fees. A small miner with daily electricity bills may prefer PPS because payments are easier to forecast. A larger operator may accept PPLNS variance if lower fees improve long-term returns. Miners running many machines can sometimes negotiate custom PPS+ or hybrid arrangements with pools.
The payout method does not change the network’s total reward. It changes how that uncertain reward is shared inside the pool. Miners should compare the formula with pool fees, minimum payout, transaction fee handling, reputation, and their own Mining Profitability estimate before choosing. A pool’s reported luck over several months can reveal whether its payout formula is holding up in practice.
