So do i need separate steem account for witness and separate on miner?
Now i have one witness node without any miner configured in. Just witness inside the config and private key.
I have also 2 mining machine with configured miner as the same user as witness in witness node. I have no witness in miners config.ini
Is it correct or do i need separate witness account to configure miner?

Witness node:
witness = "duncan-idaho"
private-key = PRIVKEY

Miner node:
miner = ["duncan-idaho","PRIV"]
mining-threads = 6

Is it correct?
