Yes, you can stake Audius.A ERC-20 token, AUDIO resides on the Ethereum blockchain, which is currently Proof of Work, but is in the process of being upgraded to a Proof of Stake consensus mechanism. The Audius network is secured by a network of node operators who have staked their AUDIO as collateral. To host their own content, artists may run their own nodes. AUDIO staked by node operators will increase the likelihood that their nodes will be used by artists and fans, enabling them to benefit from ongoing issuance and aggregated fee pools.
