For security reasons, it is recommended to separate the node and P-Rep keys.
P-Rep key is used to register a P-Rep and receive rewards.
node key is used for block consensus and is deployed on the node server. (./config/keystore.json)
A P-Rep must register the public key of its node key via setPRepNodePublicKey to vote on block consensus.
