They have something they call "seesaw" which adjusts the rewards between MN's and those just staking to stop some centralisation issues with Dash IIRC.
I think there are some other nuances but can't recall ATM
Hope you don't mind but I am going to be a little be sarcastic just for making a point. I actually appreciate you sharing the information.
So they blabbered some technobabble BS lies to make everyone think that theirs was different and improved. Yet in reality it is same old worthless shit that isn't going to be used by anybody.

. Well I think they did what most coins do. There have been several coins out there that have copied the Master Node experiment, and they have traded at low capitalisations (I held some Transfer Coin for a while when it was maybe $20k MCap IIRC)
But for one reason or another the whales have taken this for a ride.
I suspect it is because they have a team (and they might be half competent..not sure).
1. They have a dev team
2. Zero knowledge is in fashion and a worthy experiment.
3. it does not have the dash baggage ( and thus the Dash risk)
This, and the interest in alts posed by the prospect of a bitcoin hardfork has been a perfect storm.
So, I'm not sure that the dev's have been any worse than most coins, but they got lucky in that the whales chose them
Or they might have good product (I dont know)...
