Socket.io API provides a stream of events from the blockchain
Network Scanner scans the network using GRPC and hops between nodes to find all the nodes in the network
GRPC Load Balancer uses data provided from the network scanner to find the fastest nodes to communicate with
Vote Scraper makes periodic snapshots of the votes to provide historical vote data
