Introduction

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)
