Shockwave Delta v1.4

Secret Network v1.4 "Shockwave Delta" Upgrade Instructions

⚠️ IMPORTANT NOTES ⚠️

• All coordination efforts will be done in the "SN Validators" Telegram group.

• Make sure to backup your validator before making any chnages.

• Please read carefully before you begin the upgrade.

Upgrading Manually

When the network reaches the halt height 5,309,200, you'll see this message in your node's log (journalctl -fu secret-node):

1:25PM ERR UPGRADE "v1.4" NEEDED at height: 5309200:
1:25PM ERR CONSENSUS FAILURE!!! err="UPGRADE \"v1.4\" NEEDED at height: 5309200

Then, the upgrade steps for v1.4 are:

⚠️ Note: if you have modified your systemd unit file (/etc/systemd/system/secret-node.service) you will need to re-apply those changes post installation and pre service restart.

# Stop the v1.3 node, to make sure that your process manager isn't trying to restart it while you upgrade
sudo systemctl stop secret-node

# Get & verify secretd v1.4

# Check what database type you're currently using:
awk -F \" '/^db_backend =/{print $2}' ~/.secretd/config/config.toml

# Uncomment the right binary based on the database type: `rocksdb` or `goleveldb`

## goleveldb
# wget "https://github.com/scrtlabs/SecretNetwork/releases/download/v1.4.0/secretnetwork_1.4.0_mainnet_goleveldb_amd64.deb"
# echo "f96ec8e04d6c7ad919d307435045c2bf538965d7786236a4ca7655f63caee77a secretnetwork_1.4.0_mainnet_goleveldb_amd64.deb" | sha256sum --check

## rocksdb
# wget "https://github.com/scrtlabs/SecretNetwork/releases/download/v1.4.0/secretnetwork_1.4.0_mainnet_rocksdb_amd64.deb"
# echo "42d203d1eec2d4d0720d3a9d206888bd7c1385c589fcc21a11514c95fcdbc169 secretnetwork_1.4.0_mainnet_rocksdb_amd64.deb" | sha256sum --check

# Install v1.4 binaries
sudo apt install -y ./secretnetwork_1.4.0_mainnet_*_amd64.deb

# re-apply any systemd unit file customizations

# Restart the node
sudo systemctl restart secret-node

After restarting the node with v1.4, you should see INF applying upgrade "v1.4" at height: 5309200 in the logs (journalctl -fu secret-node). Once 67% of voting power comes online, you'll see blocks executing again.

Upgrading Automatically Using Cosmovisor

Cosmovisor is a new process manager for cosmos blockchains. It can make low-downtime upgrades smoother, as validators don't have to manually upgrade binaries during the upgrade, and instead can pre-install new binaries, and Cosmovisor will automatically update them based on on-chain SoftwareUpgrade proposals.

⚠️ Cosmovisor is still new and best practices for using it are not yet established. If you don't feel adventurous at this time, we recommend upgrading the manual way.

Details of Upgrade Time

When the network reaches the halt height 5,309,200, the Secret Network testnet blockchain will be halted and validators will need to take action to upgrade the chain to the secretd v1.4 binary (be it manually or automatically).

The proposal targets the upgrade proposal block to be 5,309,200, anticipated to be on Wednsday Septmber 21, 2022 at 2:00PM UTC.

The upgrade is anticipated to take approx 30 minutes, during which time, there will not be any on-chain activity on the network.

In Case of an Upgrade Failure

In the event of an issue at upgrade time, we should coordinate via the "SN Validators" Telegram group.

If as a result of a software bug the network fails to produce new blocks with the v1.4 binaries, the SCRT Labs team will distribute a v1.3 binary with an empty v1.4 upgrade handler, which will essentially allow the chain to revert to v1.3 while continuing to produce new blocks.
