Explain the ‘Pay-Per-Share’ (PPS) Method of Reward Distribution in Mining Pools.
Pay-Per-Share (PPS) is a pool reward system where miners are paid a fixed amount for every valid 'share' they submit, regardless of whether the pool actually finds a block. The pool operator absorbs the 'luck' or variance risk.
The payment is calculated based on the expected value of the block reward, normalized by the total shares required to find a block at the current difficulty.
