Verifying Stake Pool Operation
Your stake pool ID can be computed with:
air-gapped offline machine
cardano-cli stake-pool id --cold-verification-key-file $HOME/cold-keys/node.vkey --output-format hex > stakepoolid.txt
Copy stakepoolid.txt to your hot environment.
Now that you have your stake pool ID, verify it's included in the blockchain.
block producer node
cardano-cli query stake-snapshot --stake-pool-id $(cat stakepoolid.txt) --mainnet
A non-empty string return means you're registered!
