The way NKN network incentivize nodes to relay traffic is similar to what IPFS/Filecoin did to incentivize decentralized storage. There are two ways the node gets token rewards: one is by providing connectivity and relaying traffic for other nodes, another is by mining, i.e. helping record transactions on the block. The amount of tokens a node can earn is proportional to the amount and frequency of their contribution, with some probabilistic algorithms. We are designing an economic model that will encourage more nodes to join the NKN network, share extra network capacity, upgrade transmission throughput and reduce latency, and expand the network. And due to the incentive model, NKN network will be more stable and attack resistant once more nodes join the network.
