Definition
PPLNS distributes the actual block rewards (subsidy + fees) proportionally among miners who contributed shares in a defined window before the block was found. Unlike PPS/FPPS, PPLNS payments are based on actual blocks found, not theoretical expected value.
PPLNS can have higher variance (uneven payouts) since it depends on when blocks are found, but it typically has lower pool fees (0-2%) and includes the full transaction fees. Long-term average earnings are similar to FPPS, but short-term income is less predictable.
