Audius is a decentralized, community-owned music-sharing protocol and app. It provides a censorship-resistant alternative to SoundCloud that helps artists distribute anything they want directly to fans, creating a unique and differentiated catalog. The mission of the project is to give everyone the freedom to share, monetize, and listen to any audio.
This repository encompasses all of the services, contracts, and client-side libraries that comprise the Audius protocol.
For a more detailed overview of how Audius works, how these components interact with one another, how to run an off-chain service, and more, see the Audius protocol wiki for more details.
The Audius protocol has many moving pieces, on-chain and off-chain. Refer to the installation and usage instructions for any of the sub-components of the Audius protocol:
These off-chain services are run by community members via the Audius staking system:

Indexes and stores the contents of the audius contracts on the ethereum blockchain for clients to query via an API |
identity-service |
Stores encrypted auth ciphertexts, does Twitter oauth and relays transactions on behalf of users |
The independent sets of smart contracts that underpin the Audius protocol:
| Contracts | Description |
