How Is the Reward Distributed among Pool Members (Payout Schemes)?
Mining pools use various payout schemes to distribute rewards, the most common being Proportional (PPLNS), Pay-Per-Share (PPS), and Score-based (SB). PPLNS (Pay-Per-Last-N-Shares) is popular, paying miners based on the shares they contributed during a window of 'N' shares, reducing the pool's risk from 'pool hopping.'
