i don't really know how the mechanism from this staked coin output (SCO) system mate
if i'm not wrong, this is just like the other staking coin, with different rewards,,, because the reward will be a tokens that created on Nuls blockchain, right ?
I'm not sure on how their model goes but they have two different listing.
https://masternodes.online/currencies/NULS-CONSENSUS/https://masternodes.online/currencies/NULS-STAKING/The one that has the label of consensus has a projected higher profit than the staking. But the capital needed is x10 more than the staking.
After reading their site it sounds like the staking model is more so for people to buy these coins at a lower price point and use them to 'vote' for promising projects. Kind of like a precursor to ICO
