Masternode is simply a cryptocurrency full node or computer wallet that keeps the full copy of the blockchain in real-time, just like you have Bitcoin full nodes and is always up & running. Masternodes are critical for processing transactions and helping secure the network and there is need to ensure that they won’t act maliciously. That’s why operators need to put in collateral of STS which are then locked while masternode is active. In case of constant malicious behaviour of masternode, collateral will be frozen, and masternode kicked off the network.
