Full Node Build

Install pre-requisites

# 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

Follow the instructions here to install Go.

For an Ubuntu LTS, we can use:

# find location of existing GO (if any)
which go
go version

# remove old GO if existing
sudo rm -rf /usr/local/go

# install updated GO
wget https://golang.org/dl/go1.20.3.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.20.3.linux-amd64.tar.gz
rm -rf go1.20.3.linux-amd64.tar.gz

Unless you want to configure in a non standard way, then set these in the .zshrc in the user's home (i.e. ~/) folder.

nano ~/.zshrc

Add the "export Pathing" rules at the bottom, and then save the file:

# add export PATHS below
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOROOT/bin:$GOBIN

After updating your ~/.zshrc you will need to source it:

source ~/.zshrc

Build Daemon from source

git clone https://github.com/archway-network/archway
cd archway
git checkout v1.0.0-rc.2
make install

To confirm that the installation has succeeded, you can run:

archwayd version --long

Configuration of Shell Variables

For this guide, we will be using shell variables. This will enable the use of the client commands verbatim. It is important to remember that shell commands are only valid for the current shell session, and if the shell session is closed, the shell variables will need to be re-defined.

If you want variables to persist for multiple sessions, then set them explicitly in your shell .profile, as you did for the Go environment variables.

To clear a variable binding, use unset $VARIABLE_NAME. Shell variables should be named with ALL CAPS.

archwayd config keyring-backend os
archwayd config chain-id constantine-3

CHAIN_ID="constantine-3"
YOUR_MONIKER=<moniker-name>

Setting Up the Node

These instructions will direct you on how to initialize your node, synchronize to the network and upgrade your node to a validator.

Initialize the chain

Please replace YOUR_MONIKER with your own moniker.

archwayd init YOUR_MONIKER --chain-id constantine-3

This will generate the following files in ~/.archway/config/

• genesis.json

• node_key.json

• priv_validator_key.json

Download the genesis file

wget -O https://raw.githubusercontent.com/archway-network/networks/main/constantine-3/genesis.json
mv genesis.json ~/.archway/config/genesis.json

This will replace the genesis file created using archway init command with the mainnet genesis.json.

Set Seeds

sed -i 's/seeds = ""/seeds = "[e-mail]:15659"/' ~/.archway/config/config.toml

Set Persistent Peers

We can add these persistent_peers to our config.toml:

sed -i "s/persistent_peers =.*/persistent_peers = \""\"/g" "${HOME}"/.archway/config/config.toml"

Set minimum gas price

sed -i -e "s|^minimum-gas-prices *=.*|minimum-gas-prices = \"0aconst\"|" "${HOME}"/.archway/config/app.toml

Create (or restore) a local key pair

Either create a new key pair or restore an existing wallet for your validator:

# Create new keypair
archwayd keys add YOURKEY

# Restore existing juno wallet with mnemonic seed phrase.
# You will be prompted to enter mnemonic seed.
archwayd keys add YOURKEY --recover

# Query the keystore for your public address
archwayd keys show YOURKEY -a

After creating a new key, the key information and seed phrase will be shown. It is essential to write this seed phrase down and keep it in a safe place. The seed phrase is the only way to restore your keys.

Setup cosmovisor

Follow the Setup Cosmovisor instructions to setup cosmovisor and start the node.

Upgrade to a validator

Do not attempt to upgrade your node to a validator until the node is fully in sync as per the previous step.

To upgrade the node to a validator, you will need to submit a create-validator transaction:

archwayd tx staking create-validator \
--amount=1000000aconst \
--pubkey=$(archwayd tendermint show-validator) \
--moniker="<Your moniker>" \
--identity=<your identity> \
--details="<Your details>" \
--chain-id=constantine-3 \
--commission-rate=0.10 \
--commission-max-rate=0.20 \
--commission-max-change-rate=0.01 \
--min-self-delegation=1 \
--from=<YOUR_WALLET> \
--gas-prices=0.1aconst \
--gas-adjustment=1.5 \
--gas=auto \
-y

The above transaction is just an example. There are many more flags that can be set to customize your validator, such as your validator website, or keybase.io id, etc. To see a full list:

archwayd tx staking create-validator --help

Backup critical files

There are certain files that you need to back up to be able to restore your validator if, for some reason, it damaged or lost in some way. Please make a secure backup of the following files located in ~/.archway/config/:

• priv_validator_key.json

• node_key.json

It is recommended that you encrypt and backup of these files.
