Consumer chain

• Make a consumer chain proposal on the provider vi child-proposal.json

• create the proposal on the provider chain interchain-securityd tx gov submit-proposal create-child-chain ./child-proposal.json --chain-id provider --from jehan --home /provider

• Vote for the proposal interchain-securityd tx gov vote 1 yes --from jehan --chain-id provider --home /provider -b block

• Everyone preps their consumer validators

  • delete old cosmos folder if neccesary rm -rf /consumer
  • make the keys interchain-securityd keys add jehan --home /consumer

• Testnet coordinator makes genesis.json

  • init genesis interchain-securityd init jehan --chain-id consumer --home /consumer

  • add someone else to the genesis interchain-securityd add-genesis-account cosmos1t0nv6nr2scsa993ujldr7xmww5w66kcxv2cp4f 1000000000stake --home /consumer
  • get the genesis out cat /consumer/config/genesis.json
  • query the consumer genesis state from the provider interchain-securityd query parent child-genesis consumer --home /provider -o json
  • paste it into the ccvchild section of the consumer's genesis

• Everyone bootstraps their files

  • paste genesis from above into consumer folder vi /consumer/config/genesis.json
  • make empty priv validator state file echo '{"height": "0","round": 0,"step": 0}' > /consumer/data/priv_validator_state.json
  • copy the priv validator key from the provider to the consumer cp /provider/config/priv_validator_key.json /consumer/config/priv_validator_key.json
  • copy the node key from the provider to the consumer cp /provider/config/node_key.json /consumer/config/node_key.json
  • issue the gentx command (even though we will not use the created gentx) interchain-securityd gentx jehan 500000000stake --chain-id consumer --home /consumer
  • exchange peer addresses with other validators cat consumer/config/gentx/gentx-027c0fd67ee51640ac0a7e0852afeed9410e20d4.json | jq, get the address out of the body.memo for example 027c0fd67ee51640ac0a7e0852afeed9410e20d4@143.110.237.79:26656. change the port to 26646.

• Everyone starts their nodes

  • start the node, while customizing the ports (get your own IP address from the step above). We also set persistent_peers, using the addresses of other validators interchain-securityd start --home /consumer --p2p.laddr tcp://localhost:26646 --address tcp://localhost:26645 --grpc.address localhost:9081 --rpc.laddr tcp://localhost:26648 --grpc-web.enable=false --p2p.persistent_peers 027c0fd67ee51640ac0a7e0852afeed9410e20d4@143.110.237.79:26646
