"Znodes
At the same time, work will begin on Znodes, the long awaited update that allows incentivized nodes to support the Zcoin network and makes Zcoin into a hybrid Proof of Work and Proof of Stake system. Znode owners will earn a proportion of the block rewards as an incentive to maintain a full node, keep it updated and maintain the network. A certain number of Zcoin will be required as a ‘collateral’ to start a Znode to discourage Sybil attacks. This number will be announced as we come closer to launch but we aim to achieve a balance between allowing people to participate while maintaining a decent profitability for node owners to keep them sufficiently incentivized."
