Nodes are very important to the health of the network. The number of nodes affects the synchronization of clients and broadcast information speed across the entire network. The DWN master nodes network uses up to 90% of block mining as economic incentives for owners of master nodes. Any full account wallet client with above 10,000 DWN tokens can become a master node within the network, which reduces the threshold of participation, and also greatly increases the security of the network. The nodes in the DWN master node network are all nodes deployed on hosted servers worldwide. These nodes play an important cornerstone role, enabling the DWN network with extremely high concurrency processing capabilities.
