Implementing the separate PoW and PoS technologies was a feature unobtainable by the previous wave of PoW/PoS coins and allows the generation of PoS interest without affecting the PoW mining protocol because of the independent, alternating systems. Instead of stopping PoW after a few days and forking to full PoS, we’re able to maintain a shorter PoS block time to enable lightning fast transaction speed (under 5 seconds) by rapidly accelerating confirmation times without affecting the PoW blocks. In addition, the network has a constant layer of added security by modeling the coin in this manner.
Lastly, the randomized superblock payout (Jackpot) structure is unable to be exploited because the “winning” payout is confirmed by the following block. In effect, there is zero indication prior to awarding the payout which eliminates any potential discrepancies. (i.e. Multi-pools ability to select largest payouts)
