Installation

Full Node Setup

1. System requirements

Ubuntu must be 22.04 or newer.

Node	RAM	DRIVE	CPU
Validator node	16GB	1TB	4cores
Full node	8GB	1TB	2cores

2. Manual installation

2.1 Set up variables

CHAIN_ID="namada.5f5de2dd1b88cba30586420"
WALLET_ALIAS="<SET YOUR WALLET ALIAS>"
VALIDATOR_ALIAS="<SET YOUR VALIDATOR ALIAS>"

Export variables:

echo "export WALLET_ALIAS="$WALLET_ALIAS"" >> $HOME/.bash_profile
echo "export VALIDATOR_ALIAS="$VALIDATOR_ALIAS"" >> $HOME/.bash_profile
echo "export WORKING_DIR="$HOME/.local/share/namada"" >> $HOME/.bash_profile
echo "export PUBLIC_IP=$(wget -qO- eth0.me)" >> $HOME/.bash_profile
echo "export CHAIN_ID="$CHAIN_ID"" >> $HOME/.bash_profile
source $HOME/.bash_profile

2.2 Install prerequisites

Update packages and install dependencies:

sudo apt update && sudo apt upgrade -y
sudo apt-get install -y curl git jq lz4 make git-core libssl-dev pkg-config libclang-12-dev build-essential protobuf-compiler

Install Go:

sudo rm -rf /usr/local/go
curl -Ls https://go.dev/dl/go1.20.10.linux-amd64.tar.gz | sudo tar -xzf - -C /usr/local
eval $(echo 'export PATH=$PATH:/usr/local/go/bin' | sudo tee /etc/profile.d/golang.sh)
eval $(echo 'export PATH=$PATH:$HOME/go/bin' | tee -a $HOME/.profile)

Install Rust:

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

Install CometBFT:

cd $HOME
rm -rf cometbft
git clone https://github.com/cometbft/cometbft.git
cd cometbft
git checkout v0.37.11
make build
sudo cp $HOME/cometbft/build/cometbft /usr/local/bin/
cometbft version

2.3 Install Namada binary

cd $HOME
rm -rf namada
git clone https://github.com/anoma/namada
cd namada
wget https://github.com/anoma/namada/releases/download/v1.0.0/namada-v1.0.0-Linux-x86_64.tar.gz
tar -xvf namada-v1.0.0-Linux-x86_64.tar.gz
rm namada-v1.0.0-Linux-x86_64.tar.gz
cd namada-v1.0.0-Linux-x86_64
sudo mv namad* /usr/local/bin/
if [ ! -d "$WORKING_DIR" ]; then
    mkdir -p "$WORKING_DIR"
fi

Check namada version:

namada --version

2.4 Initialize the chain configuration

For genesis validators:

namada client utils join-network --chain-id $CHAIN_ID --genesis-validator $VALIDATOR_ALIAS

For post-genesis validators and Full nodes:

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

Check everything works fine :

namadac epoch

Output should be like: "Last committed epoch: 150"

2.5 Create service file

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

[Service]
User=$USER
WorkingDirectory=$WORKING_DIR
Environment=TM_LOG_LEVEL=p2p:none,pex:error
Environment=NAMADA_CMT_STDOUT=true
Environment=NAMADA_LOG=info
ExecStart=$(which namada) node ledger run
StandardOutput=syslog
StandardError=syslog
Restart=always
RestartSec=10
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

2.6 Start a node

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

3. Adding wallets

3.1 Add new keypair (or restore)

namada wallet gen --alias $WALLET_ALIAS

or restore:

namada wallet derive --alias $WALLET_ALIAS --hd-path default

3.2 Check keys

namada wallet find --alias $WALLET_ALIAS

Wait until the node is synchronized.

Command to check your node status ("latest_block_height" should be not 0 and "catching up" - false):

curl localhost:26657/status | jq 

3.3 Check key balance

namada client balance --owner $WALLET_ALIAS

4. Validator Setup

Following validator setup is optional for Crew Members. Wait until your node is synced!

Command to check your node status ("latest_block_height" should be not 0 and "catching up" - false):

curl localhost:26657/status | jq 

4.1 Create validator

namada client init-validator \
 --alias $VALIDATOR_ALIAS \
 --account-keys $WALLET_ALIAS \
 --signing-keys $WALLET_ALIAS \
 --commission-rate 0.1 \
 --max-commission-rate-change 0.1 \
 --email <ENTER YOUR EMAIL>

4.2 Restart your node

systemctl restart namadad

4.3 Stake (bond) your validator

namada client bond --source $WALLET_ALIAS  --validator $VALIDATOR_ALIAS  --amount 100

Wait > 2 epochs and then check bond status.

4.4 Check your validator status

namada client bonds --owner $WALLET_ALIAS
