In exchange for having a certain amount of collateral in your wallet, you can set up a masternode that gets a share of the reward, every time a block is found. In this case, the share would be 75% of the reward. In return, your masternode should do something called coin mixing. It will also help with processing dark send and instant tx transactions. Masternodes actually do this function with Dash. Furthermore, unless Masternodes are enforced, there is a way someone can bypass this and have a wallet that does not pay to Masternodes. It appears many of the masternode plus POS 2.0 clones do not do this function properly, from what I can determine. Could be wrong....I'm probably not going to be involved in this coin unless the Masternodes actually do what they are supposed to and are enforced like in Dash. Of course, over 1.3 BTC needed to get a Masternode is a big investment. Probably out of my price range anyway.
I still dont understand the need for a masternode or what it really does for the coin. Does it help to secure the network or is it just a giant mixer?
Others feel free to correct me if I am wrong, but above and beyond the large staking master nodes ensure a stable and "always on" situation for the network. This is especially essential in this sort of project, where apparently users will be able to choose to have their outgoing transactions vetted by the network as an extra precaution against hacks. If you are doing that sort of thing, you want a very robust network.
