The Pay-Per-Share Payment Method offers an instant, guaranteed payout to a miner for their contribution to the probability that the pool finds a block. This method allows for the least possible variance in payment for the miners while transferring the risk to the pool operator as miners are paid regardless if the pool finds a block.
We pay PPS regardless of orphans or rejects. Which means that the actual fee is lower. With Luxor, miners get paid for every share, no waiting and no confirmations.
Miners are paid from the pool’s existing balance and can withdraw their money immediately.
PPS forces the mining pool to be accountable for it's luck. If a pool is PPLNS, the operator doesn't care if the pool has good or bad luck, they get their percentage regardless. It's the miners who suffer. By choosing to be PPS, Luxor is saying "We've built a rock solid pool that we guarantee is profitable".
