1. Installing new Namada Full Node & Validator

1.1 ENV Params

cd ~ 
NAMADA_TAG="v0.28.0"
NAMADA_CHAIN_ID="public-testnet-7.0.3c5a38dc983"
TM_HASH="v0.1.4-abciplus"
VALIDATOR_ALIAS="yourNode"

1.2 Install and update dependency

sudo apt update -y
sudo apt upgrade -y
sudo apt install curl make clang pkg-config libssl-dev build-essential git jq ncdu bsdmainutils  -y
apt-get install protobuf-compiler -y
apt install pkg-config libusb-1.0-0-dev libftdi1-dev -y
apt-get install libudev-dev -y

1.3 Installing Rustc

cd ~ 
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
#Press 1 to install
source "$HOME/.cargo/env"
rustup show

1.4 Installing Go (required by Tendermint)

goVer="1.19.4"
cd ~
wget "https://golang.org/dl/go$goVer.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$goVer.linux-amd64.tar.gz"
rm "go$goVer.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> ~/.bash_profile
source ~/.bash_profile
go version

1.5 Installing Tendermint

cd ~ 
sudo rm -rf tendermint 
git clone https://github.com/heliaxdev/tendermint && cd tendermint && git checkout $TM_HASH
make build
sudo mv build/tendermint /usr/local/bin/
tendermint version

1.6 Installing Namada

cd ~ && sudo rm -rf $HOME/namada 
git clone https://github.com/anoma/namada 
cd namada 
git checkout $NAMADA_TAG
make build-release
sudo mv target/release/namada /usr/local/bin/
sudo mv target/release/namada[c,n,w] /usr/local/bin/
namada -V

1.7 Config Namada Service

echo "[Unit]
Description=Namada Node
After=network.target

[Service]
User=$USER
WorkingDirectory=$HOME/.namada
Type=simple
ExecStart=/usr/local/bin/namada --base-dir=$HOME/.namada node ledger run
Environment=NAMADA_TM_STDOUT=true
RemainAfterExit=no
Restart=always
RestartSec=5s
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target" > $HOME/namadad.service
sudo mv $HOME/namadad.service /etc/systemd/system
sudo tee <<EOF >/dev/null /etc/systemd/journald.conf
Storage=persistent
EOF
sudo systemctl restart systemd-journald
sudo systemctl daemon-reload
sudo systemctl enable namadad

1.8 Join Testnet 15

cd ~
namada client utils join-network --chain-id $NAMADA_CHAIN_ID

1.9 Start Namada Service

sudo systemctl start namadad

2.Config Validator Address

You will have 3 Address: Main Namada Address(private) > consensus-key address > validator-key address (public)

Create new Main Namada Address

cd ~
namada wallet address gen --alias yourMainWalletAliasName

Initialising Validator account (Validator-key and Consesum-key address)

cd ~
namada client init-validator \
  --alias $VALIDATOR_ALIAS_NAME \
  --source yourMainWalletAliasName \
  --commission-rate 0.1 \
  --max-commission-rate-change 0.1

Get tokens from the faucet

namadac transfer \
  --token NAM \
  --amount 1000 \
  --source faucet \
  --target $VALIDATOR_ALIAS_NAME \
  --signer $VALIDATOR_ALIAS_NAME

You can faucet for any Namada address by alias name or specific address of that address. In this example I use validator address.

You can faucet as many times as you want to get as many test tokens as you want

Bond token to your validator

namada client bond \
  --validator $VALIDATOR_ALIAS_NAME \
  --amount 1000

By default, if you do not specify the source, it will be taken from the validator address. Of course you can also specify from any other address you own eg Your main Nameda address or something else

namada client bond \
  --source $WALLET \
  --validator $VALIDATOR_ALIAS \
  --amount 3000

• If you get an error, please try again in a few minutes

Done !

If all goes well, you have now become a validator.

3. Node Operation

Node

Check Node Info

curl -s localhost:26657/status

Check Log

journalctl -u namadad -f

Check current height

sudo journalctl -u namadad -n 10000 -f -o cat | grep height

Restart service

Systemctl restart namadad

Check free disk space

df -hT / --total | awk '/^total/ {print "Total disk size: "$3" | Used:" $4 " | Avaliable:" $5 " | Usage:" $6}'

Account

Check the ballance

namada client balance --owner $WALLET_ALIAS_NAME_OR_FULL_ADDRESS --token NAM

Check your Votepower

namada client bonded-stake | grep $VALIDATOR_ADDRESS

Show all validator in Namada Blockchain

namada client bonded-stake

Check total bonds (Bonds require 2 epoch to be activated)

namadac bonds --validator $VALIDATOR_ALIAS

Check current Epoch

namadac epoch

Unbonds

namada client unbond \
  --source $WALLET \
  --validator $VALIDATOR_ALIAS \
  --amount 1.2

Send token to another address

namada client transfer \
  --source $WALLET_ALIAS \
  --target $RECIVE_WALLET_ADDRESS \
  --token NAM \
  --amount 1000

4. QA and Error Handle

The address doesn’t belong to any known validator account

• Check your node is synced or not. Double check that the addresses you entered are correct. If everything is correct wait 1 - 2 epoch then try again.

INFO namada_apps::cli::context: Chain ID: namada-internal.00000000000000
The application panicked (crashed).
Message:  called `Result::unwrap()` on an `Err` value:
   0: couldn't read genesis config file from .namada/namada-internal.00000000000000.toml
   1: No such file or directory (os error 2)
Location:
   apps/src/lib/config/genesis.rs:687

• Let's go back to the home directory "cd ~"

5. Update Namada Validator Node (Post-genesis Validator Only)

Currently, Namada Testnet version allows export of private keys but does not support automatic import of private keys. There is also no recommendation from Namada Team to request the use of addresses from the previous testnet as proof of contribution. So simple to update to the new version, you can delete the old version then reinstall new version. Of course there is still a manual way to do it if you have a need to do so please leave an issue in this Repo. We will add a new article on how to manually export and import Namada accounts (if it's a real need).

To delete and reinstall Namada do the following:

Stop Namadad service

systemctl stop namadad

Remove Namada Data

cd ~
sudo rm -rf .namada

Pull new Namada version

NAMADA_TAG="v0.15.1"
NAMADA_CHAIN_ID="public-testnet-7.0.3c5a38dc983"
cd ~/namada
git fetch
git checkout $NAMADA_TAG
make build-release
sudo mv target/release/namada /usr/local/bin/
sudo mv target/release/namada[c,n,w] /usr/local/bin/
namada -V
cd ~
