This command will let you vote for a proposal to stop a consumer chain using the CLI

  1. Check the state of the IBC channel used by the CCV protocol. You can see that it is still running because the consumer chain is still running.
PROV_NODE_DIR=~/provider
PROV_CHAIN_ID=provider
CHANNEL_ID=channel-0

interchain-security-pd q ibc channel end $PROV_CHAIN_ID $CHANNEL_ID --home $PROV_NODE_DIR
  1. See proposals on the blockchain
interchain-security-pd q gov proposals --home $PROV_NODE_DIR

You should see a proposal called "Stop the first consumer", with chain_id: consumer Check what the proposal_id is, and input it as PROP_ID below.

  1. Now vote for the proposal
PROP_ID=9
PROV_KEY=provider-key

interchain-security-pd tx gov vote $PROP_ID yes --from $PROV_KEY \
       --keyring-backend test --chain-id $PROV_CHAIN_ID --home $PROV_NODE_DIR -b block -y

Check that your vote was added to the proposals total yes votes:

interchain-security-pd q gov tally 9 --home $PROV_NODE_DIR

Once the voting period is over

  1. Verify that the proposal passed and check the IBC channel's state again
interchain-security-pd q gov proposal $PROP_ID --home ${PROV_NODE_DIR}
interchain-security-pd q ibc channel end $PROV_CHAIN_ID $CHANNEL_ID --home $PROV_NODE_DIR

It should have been updated to "STATE_CLOSED"

  1. Check that the consumer chain has stopped
CONS_NODE_DIR=~/consumer
cat ${CONS_NODE_DIR}/logs | grep -m 1 "shutdown consumer chain since it is not secured anymore"

You will see where the consumer chain stopped itself once the channel was closed. For example: 4:46PM ERR CCV channel "channel-0" was closed - shutdown consumer chain since it is not secured anymore
