It is entirely unique, mining is somewhat derived from "masternodes" though. A node on the network is simply a device that is verifying the transactions. Rewards are constant to incentivize users who are worried about electricity, difficulty, etc.
So a similar reward mechanism however nodes are the only way to mine with there being no bond or staking like in other custom algos. ONC works in a similar way to a mesh network.  Hope this helps and thanks for your interest!
