Configure ENV variables

export GH_URL=github.com/regen-network/regen-ledger
export CHAIN_VERSION=v1.0.0
export UPGRADE_VERSION=v1.1.0-alpha0
export DENOM=uregen
export CHAINID=testnet
export NODE=http://localhost:26657
export DAEMON=regen
export DAEMON_HOME=~/.regen

export GOBIN=$GOPATH/bin

Start testnet and handle proposal:

./scripts/testnet-setup-plan-upgrade.sh

The script will start the testnet. It creates a software-upgrade proposal, sends deposit and votes for it.

Just wait for the chain to hit upgrade height and chain will halt there.

You can check sudo service $DAEMON status for the current height or query the chain consensus_state using curl http://localhost:26657/consensus_state

Handle upgrade

Ensure you execute this script only after hitting the upgrade height (i.e., 80 as mentioned in the testnet setup script)

Check the $DAEMON status to confirm if the chain is waiting for the upgrade. sudo service $DAEMON status

You should see a message like: UPGRADE "<upgrade-name-here>" NEEDED at height: 150: module=main

./scripts/handle-upgrade.sh

Check the $DAEMON status, it should start producing the blocks again. sudo service $DAEMON status
