This section describes how to run an Audius node.

The Audius protocol is powered by two off-chain services, the Discovery Node and the Content Node.

Discovery Node

  • Indexes blockchains used by the Audius protocol (Main-net Ethereum, POA, and Solana)
  • Serves API traffic
  • Tracks usage metrics

Content Node

  • Hosts audio and image content
  • Syncs content across nodes to ensure data is consistent and highly available (using the Audius Storage Protocol under the hood)
