cosmos-valset-exporter is a Node.js application that exports Cosmos validator set information to Prometheus metrics. The application connects to a Cosmos node via a WebSocket and listens for new block events. When a new block event is received, the application fetches the validator set and the list of active validators and exports this information to Prometheus.
