Can someone explain to me how does PPLNS mining pool profit split in lay terms?
As you mine, you earn shares. The more hashes you do, the more shares you earn. PPLNS means that every time the pool mines a block, shares of the reward are distributed to the miners that mined the most recent shares. Often, N is chosen as twice the difficulty. So if, on average, a block will be found every one billion shares, the block reward is divided to those who submitted the last two billion shares when the block was found.
