- Ensures ports remain open and client are responsive to IX requests. - Completely 100% decentralized. This farms out the work of checking the masternode network to the masternode network. 1% of the network is determistically selected to check another 1% of the network each block. It takes six separate checks to deactivate a node, thus making it tamper proof. - Nodes are kept in the masternode list if they fail enough PoSe checks to deactivate. They will continue to be checked until the operator fixes them. However they will not be paid while they're failing checks.
