In StaFi rKSM SRMS algorithm, it is very important to select the professional and high-quality validators to join as the Original Validators (OV), and ask them to set a reasonably low commission rate to provide higher APY for stakers. The rKSM App will monitor and evaluate the performance data of original validator candidates from the metrics including active rate, slashing record, self-bond ratio, node identity, commission ratio, etc., to ensure that excellent validators with relatively low commission are selected.
