What Does ‘N’ Represent in the PPLNS Fee Structure?

'N' in Pay-Per-Last-N-Shares represents the number of shares in the last "window" or "round" of mining that will be considered for a payout when a block is found. This 'N' is typically set to be much larger than the expected number of shares needed to find a block.

It is a moving window that ensures miners who leave the pool immediately after a block is found do not receive a disproportionate share of the next block's reward.
