An Audius Discovery Node is a service that indexes the metadata and availability of data across the protocol for Audius users to query. The indexed content includes user, track, and album/playlist information along with social features. The data is stored for quick access, updated on a regular interval, and made available for clients via a RESTful API.

Design Goals

  1. Expose queryable endpoints which listeners/creators can interact with
  2. Reliably store relevant blockchain events
  3. Continuously monitor the blockchain and ensure stored data is up to date with the network

The Discovery Node may be referred to as the Discovery Provider. These services are the same.
