Node Installation

  • Install Prerequisites

# update the local package list and install any available upgrades
sudo apt-get update && sudo apt upgrade -y

# install toolchain and ensure accurate time synchronization
sudo apt-get install make build-essential gcc git jq chrony -y

  • Install Go

# download the latest version
wget https://go.dev/dl/go1.20.6.linux-amd64.tar.gz

# remove old version (if any)
sudo rm -rf /usr/local/go

# install the new version
sudo tar -C /usr/local -xzf go1.20.6.linux-amd64.tar.gz

  • Configure Environmental Variables

# run these commands
cat <<EOF >> ~/.profile
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GO111MODULE=on
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
EOF

source ~/.profile

go version

The output should be go version go1.20.6 linux/amd64

  • Install Chihuahua from sources

# run these commands
git clone https://github.com/ChihuahuaChain/chihuahua.git
cd chihuahua
git fetch --tags
git checkout v4.2.3
make install

To verify the installation you can run chihuahuad version and it should return v4.2.3

  • Initialize the Chain

Replace $MONIKERNAME with your choosen node name

chihuahuad init $MONIKER_NAME --chain-id woofnet-1

  • Download the Genesis

wget -O ~/.chihuahuad/config/genesis.json https://raw.githubusercontent.com/ChihuahuaChain/testnet/main/genesis.json

  • Add Persistent Peers

peers="[email protected]:36656"
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" ~/.chihuahuad/config/config.toml

  • Update minimum-gas-price in app.toml

sed -i.bak 's/minimum-gas-prices =.*/minimum-gas-prices = "1uhuahua"/' $HOME/.chihuahuad/config/app.toml

  • Setting up Cosmovisor

Install cosmovisor

go install github.com/cosmos/cosmos-sdk/cosmovisor/cmd/cosmovisor@latest

which cosmovisor

# should return
'/home/<your-user>/go/bin/cosmovisor'

# run these commands
cat <<EOF >> ~/.profile
export DAEMON_NAME=chihuahuad
export DAEMON_HOME=$HOME/.chihuahuad
EOF

source ~/.profile

echo $DAEMON_NAME

# should return
'chihuahuad'

# create the directories
mkdir -p $DAEMON_HOME/cosmovisor/genesis/bin
mkdir -p $DAEMON_HOME/cosmovisor/upgrades

# check the binary path with
which chihuahuad

# this should return
'/home/your-user/go/bin/chihuahuad'

# copy the binary into
cp $(which chihuahuad) $DAEMON_HOME/cosmovisor/genesis/bin

Set up the service file

sudo nano /etc/systemd/system/woofnet.service

# paste and edit <your-user> with your username
[Unit]
Description=Chihuahua Testnet Daemon (cosmovisor)
After=network-online.target

[Service]
User=<your-user>
ExecStart=/home/<your-user>/go/bin/cosmovisor run start
Restart=always
RestartSec=3
LimitNOFILE=4096
Environment="DAEMON_NAME=chihuahuad"

Environment="DAEMON_LOG_BUFFER_SIZE=512"
Environment="UNSAFE_SKIP_BACKUP=True"

[Install]
WantedBy=multi-user.target

Enable the service

sudo -S systemctl daemon-reload
sudo -S systemctl enable woofnet

  • Start the node

You can start the node by running

sudo systemctl start woofnet

# check the logs by running
journalctl -u woofnet -f

The node will take some time to catch-up with the blockchain. You can follow the blocks being indexed by rnning

journalctl -u woofnet -f | grep indexed

Join the Validators (testnet)

ChihuahuaChain Governance voted a proposal enabling the minimum 5% Commission enforced by the blockchain, this enforcement works in testnet too!

# create a new wallet for the validator

chihuahuad keys add <key-name>

# save the seed phrase (mnemonic) in a safe place
# copy the 'chihuahua...' address and send some HUAHUA
# in order to pay for the validator creation's transaction

# Make sure the Validator has fully synced before running
chihuahuad tx staking create-validator \
  --from "<key-name>" \
  --amount "1000000uhuahua" \
  --pubkey "$(chihuahuad tendermint show-validator)" \
  --chain-id "woofnet-1" \
  --moniker "<moniker>" \
  --commission-max-change-rate 0.01 \
  --commission-max-rate 0.20 \
  --commission-rate 0.10 \
  --min-self-delegation 1 \
  --details "<details>" \
  --security-contact "<contact>" \
  --website "<website>" \
  --gas-prices "1uhuahua"

# Make sure to backup the priv_validator_key.json file in your
# /home/<your-user>/.chihuahuad/config directory
# and store it in a safe place

Congratulation! Your Testnet node should be up and running

_Make sure to join our Discord and join our Testnet channel so we can send you some testnet HUAHUA for you to play with! Woof!
