System Update and Dependency Installation

Begin by updating your system's package list and upgrading existing packages. Then, install necessary dependencies:

sudo apt update && sudo apt upgrade -y
sudo apt-get install -y make git-core libssl-dev pkg-config libclang-12-dev build-essential protobuf-compiler

Go Installation

Proceed with installing Go if it isn't already present on your system:

cd $HOME
if ! command -v go &> /dev/null; then
    VER="1.20.3"
    wget "https://golang.org/dl/go$VER.linux-amd64.tar.gz"
    sudo rm -rf /usr/local/go
    sudo tar -C /usr/local -xzf "go$VER.linux-amd64.tar.gz"
    rm "go$VER.linux-amd64.tar.gz"
    echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
    source $HOME/.bash_profile
fi

Setting Up Environment Variables

Customize your setup by replacing placeholders with your specific details and save them as environment variables:

NAMADA_PORT=26
echo "export NAMADA_PORT=$NAMADA_PORT" >> $HOME/.bash_profile
echo "export ALIAS='YOUR_VALIDATOR_NAME'" >> $HOME/.bash_profile
echo "export MEMO='YOUR_TPK_NAM_ADDRESS'" >> $HOME/.bash_profile
echo "export WALLET='YOUR_WALLET_NAME'" >> $HOME/.bash_profile
echo "export PUBLIC_IP=$(wget -qO- eth0.me)" >> $HOME/.bash_profile
echo "export TM_HASH='v0.1.4-abciplus'" >> $HOME/.bash_profile
echo "export CHAIN_ID='shielded-expedition.88f17d1d14'" >> $HOME/.bash_profile
echo "export BASE_DIR='$HOME/.local/share/namada'" >> $HOME/.bash_profile
source $HOME/.bash_profile

Rust and CometBFT Installation

Install Rust and set up CometBFT for enhanced security and performance:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
source $HOME/.cargo/env

cd $HOME
git clone https://github.com/cometbft/cometbft.git
cd cometbft
git checkout v0.37.2
make build
sudo cp build/cometbft /usr/local/bin/
cometbft version

Namada Binaries Setup

Download and prepare Namada binaries:

cd $HOME
git clone https://github.com/anoma/namada
cd namada
wget https://github.com/anoma/namada/releases/download/v0.31.9/namada-v0.31.9-Linux-x86_64.tar.gz
tar -xvf namada-v0.31.9-Linux-x86_64.tar.gz
sudo mv namad* /usr/local/bin/
if [ ! -d "$BASE_DIR" ]; then
    mkdir -p "$BASE_DIR"
fi

Verifying Namada Installation

Ensure Namada has been installed correctly:

namada --version

Finalizing the Installation

Join the network as a Pre-Genesis Validator, configure your node, and set up Namada as a service.

Joining the Network

namada client utils join-network --chain-id $CHAIN_ID

Service Configuration

Create a systemd service file for Namada to ensure it runs smoothly:

sudo tee /etc/systemd/system/namadad.service > /dev/null <<EOF
[Unit]
Description=Namada Service
After=network-online.target

[Service]
User=$USER
WorkingDirectory=$BASE_DIR
ExecStart=$(which namadad) node ledger run
Restart=always
RestartSec=10
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

Add peers to config.toml

PEERS="tcp://d630c49e04eb60a2c9e179a1a3001313fbaff061@seed.namada.posthuman.digital:26656,tcp://7233f22a664457479a6b194f590f2db95c726240@namada-testnet-peer.itrocket.net:33656,tcp://95d58c49e8177dbb67ded1475381011b7c28c375@116.202.241.157:26656,tcp://8a9872e2502be4fd2664dc1477020f36a38a4940@5.78.71.104:26656"
sed -i 's|^persistent_peers *=.*|persistent_peers = "'$PEERS'"|' $HOME/.local/share/namada/shielded-expedition.88f17d1d14/config.toml

Use our snapshot service here to sync really quick!

Set custom ports in config.toml:

sed -i.bak -e "s%:26658%:${NAMADA_PORT}658%g;
s%:26657%:${NAMADA_PORT}657%g;
s%:26656%:${NAMADA_PORT}656%g;
s%:26545%:${NAMADA_PORT}545%g;
s%:8545%:${NAMADA_PORT}545%g;
s%:26660%:${NAMADA_PORT}660%g" $HOME/.local/share/namada/shielded-expedition.88f17d1d14/config.toml

start the service

sudo systemctl daemon-reload
sudo systemctl enable namadad
sudo systemctl restart namadad && sudo journalctl -u namadad -f

🔎 Create and Fund Wallet

Create Wallet:

namadaw gen --alias $WALLET

Restore Existing Wallet:

namadaw derive --alias $WALLET

Find Your Wallet Address:

namadaw find --alias $WALLET

• Copy the implicit address (starts with tnam...) for the next step.

Fund Your Wallet from Faucet here

• After a couple of minutes, check the balance:

namadac balance --owner $WALLET

List Known Keys and Addresses in the Wallet:

namadaw list

Check Sync Status:

• Once your node is fully synced, the output will confirm:

curl http://127.0.0.1:26657/status | jq

🧑‍🎓 Turn Your Full Node into a Validator

Initiate a Validator:

namadac init-validator \
    --commission-rate 0.07 \
    --max-commission-rate-change 1 \
    --signing-keys $WALLET \
    --alias $ALIAS \
    --email <EMAIL_ADDRESS> \
    --website <WEBSITE> \
    --discord-handle <DISCORD> \
    --account-keys $WALLET \
    --memo $MEMO

Find Your Validator Address:

namadaw list | grep -A 1 ""$ALIAS"" | grep "Established"

Check Your Validator Address and Save:

namadaw list | grep "Established"

Wait for 2 Epochs and Restart the Node

sudo systemctl restart namadad && sudo journalctl -u namadad -f
