Overview

Thank you for submitting a gentx! This guide will provide instructions on getting ready for the testnet.

The Chain Genesis Time is 17:00 UTC on July 19, 2021.

Please have your validator up and ready by this time, and be available for further instructions if necessary at that time.

The primary point of communication for the genesis process will be the #validators channel on the Stargaze Discord.

Instructions

This guide assumes that you have completed the tasks involved in Part 1. You should be running on a machine that meets the hardware requirements specified in Part 1 with Go installed. We are assuming you already have a daemon home ($HOME/.starsd) setup.

These examples are written targeting an Ubuntu 20.04 system. Relevant changes to commands should be made depending on the OS/architecture you are running on.

Update starsd to v0.10.0

Please update to the v0.10.0 tag and rebuild your binaries.

git clone https://github.com/public-awesome/stargaze
cd stargaze
git checkout v0.10.0

make install

Verify installation

Verify that everything is OK.

starsd version --long

name: starsd
server_name: starsd
version: 0.10.0
commit: eaa79abdf2942b143362aa15cfc204b4d977270b
build_tags: netgo,ledger
go: go version go1.16.4 linux/amd64

If the software version does not match, then please check your $PATH to ensure the correct starsd is running.

Save chain-id in config

Please save the chain-id to your client.toml. This will make it so you do not have to manually pass in the chain-id flag for every CLI command.

starsd config chain-id cygnusx-1

Install and setup Cosmovisor

We highly recommend validators use cosmovisor to run their nodes. This will make low-downtime upgrades more smoother, as validators don't have to manually upgrade binaries during the upgrade, and instead can preinstall new binaries, and cosmovisor will automatically update them based on on-chain SoftwareUpgrade proposals.

You should review the docs for cosmovisor located here: https://docs.cosmos.network/master/run-node/cosmovisor.html

If you choose to use cosmovisor, please continue with these instructions:

Cosmovisor is currently located in the Cosmos SDK repo, so you will need to download that, build cosmovisor, and add it to you PATH.

git clone https://github.com/cosmos/cosmos-sdk
cd cosmos-sdk
git checkout v0.42.7
make cosmovisor
cp cosmovisor/cosmovisor $GOPATH/bin/cosmovisor
cd $HOME

After this, you must make the necessary folders for cosmosvisor in your daemon home directory (~/.starsd).

mkdir -p ~/.starsd
mkdir -p ~/.starsd/cosmovisor
mkdir -p ~/.starsd/cosmovisor/genesis
mkdir -p ~/.starsd/cosmovisor/genesis/bin
mkdir -p ~/.starsd/cosmovisor/upgrades

Cosmovisor requires some ENVIRONMENT VARIABLES be set in order to function properly. We recommend setting these in your .profile so it is automatically set in every session.

echo "# Setup Cosmovisor" >> ~/.profile
echo "export DAEMON_NAME=starsd" >> ~/.profile
echo "export DAEMON_HOME=$HOME/.starsd" >> ~/.profile
source ~/.profile

Finally, you should copy the starsd binary into the cosmovisor/genesis folder.

cp $GOPATH/bin/starsd ~/.starsd/cosmovisor/genesis/bin

This will create a new .starsd folder in your HOME directory.

Generate genesis file

Stargaze comes with a script to generate the genesis file required to start the chain. Therefore, no single party is responsible for starting the chain. Each validator generates their own genesis file, which should be identical for all.

If you don't already have the networks repo cloned:

git clone https://github.com/public-awesome/networks
cd networks

Update to the latest:

git checkout master
git pull

Build the genesis file:

./build-genesis.sh

NOTE: This can take 10-30 minutes depending on your setup.

Verify your genesis file was created properly:

sha256sum ~/.starsd/config/genesis.json
d5baa2f54fbd4b0c84967e0b8a59bfa26ee5da6230da44f1f13624626cb3e927

NOTE: You will need to install jq if you haven't already for the above to work.

Updates to config files

You should review the config.toml and app.toml that was generated when you ran starsd init last time.

When it comes the min gas fees, our recommendation is to leave this blank for now (charge no gas fees), to make the UX as seamless as possible for users to be able to pay with IBC assets. So in app.toml:

minimum-gas-prices = ""

Reset chain DB

There shouldn't be any chain database yet, but in case there is for some reason, you should reset it.

starsd unsafe-reset-all

Start your node

Now that everything is setup and ready to go, you can start your node.

cosmovisor start

You will need some way to keep the process always running. If you're on linux, you can do this by creating a service.

sudo tee /etc/systemd/system/starsd.service > /dev/null <<EOF
[Unit]
Description=Stargaze Daemon
After=network-online.target

[Service]
User=$USER
ExecStart=$(which cosmovisor) start
Restart=always
RestartSec=3
LimitNOFILE=4096

Environment="DAEMON_HOME=$HOME/.starsd"
Environment="DAEMON_NAME=starsd"
Environment="DAEMON_ALLOW_DOWNLOAD_BINARIES=false"
Environment="DAEMON_RESTART_AFTER_UPGRADE=true"

[Install]
WantedBy=multi-user.target
EOF

Then update and start the node

sudo -S systemctl daemon-reload
sudo -S systemctl enable starsd
sudo -S systemctl start starsd

You can check the status with:

systemctl status starsd

Conclusion

Good luck! See ya in the Discord!
