I am running a new cardano node.
my understanding is that only the following keys and certificates should remain in the hot environment (Producer node) for security:
kes.skey
vrf.sky
node.cert
other than those key, I only have the topology (.json) files and the payment.addr (payment address) file.
should the payment.addr file remain in the hot environment or should it be moved and stored in the cold air gapped machine???
