In order to operate an Aleph Core Channel node and earn rewards, you must have:
200,000 ALEPH to register your node
At least 500,000 ALEPH staked in your node to start earning and get your node in “Active” Status
The 200,000 ALEPH will allow you to register a Core Channel node on account.aleph.im. The additional 500,000 ALEPH needs to be staked against your node, and can either be your own ALEPH (in a separate wallet) or community stakers joining your node.
