PPS (Pay Per Share)

Classic PPS pays each share its expected value of the block subsidy, immediately and unconditionally. Unlike FPPS it excludes transaction fees, which the pool keeps — a meaningful difference on Bitcoin, where fees can be a substantial revenue component during congestion.

Pure PPS has largely given way to FPPS (which adds fee pass-through) and PPS+ hybrids. When comparing pools, always check which scheme the advertised fee applies to — a low fee on PPS can net less than a higher fee on FPPS.
