Autheo Node Setup

This is a deprecated article. Please see the updated article for information about creating a new validator node on the Autheo Testnet.

The following document outlines the steps necessary to setup your Autheo validator node. You will need Ubuntu 22.04 for this process.

Cloning Node Software

You can either download the node software binary from Github directly or use the following CLI command to clone the repository locally:

git clone git@github.com:autheo-platform/testnet.git
cd testnet
pip3 install pystarport

After cloning the repo, you will need to build the binary using the following command:

make build

Finally, you can verify successful installation by checking your autheod version:

autheod version

Adjust `authd` and `rpc.sh` Files

You will need to move the authd binary located in user/local/bin.

In the cloned node repo, you will find the file rpc.sh. You will need to update the NODE_NUMBER variable to the current number of nodes, plus one. Therefore, if there are currently 4 nodes, your NODE_NUMBER should be 5. Verify that the contents appear as follows:

*********************************************
#!/bin/bash
 
 
 
LOGLEVEL="debug"
NODE_NUMBER=3
CONST_NODE_NAME="auth-rpc-node"
CHAINID="auth_ChainID-1"
 
 
 
# Set the script directory
SCRIPT_DIR=$( cd -- "$( dirname -- "${BASH_SOURCE[0]}" )" &> /dev/null && pwd )
HOMEDIR="${SCRIPT_DIR}/${CONST_NODE_NAME}${NODE_NUMBER}"
 
 
 
# Function to set up the Ethereum node
function setupNode() {
  mkdir -p "${HOMEDIR}/config"
 
 
 
  # Initialize the node
  authd config keyring-backend "file" --home "$HOMEDIR"
  authd config chain-id "$CHAINID" --home "$HOMEDIR"
  authd config node "tcp://${CONST_NODE_NAME}${NODE_NUMBER}:26657" --home "$HOMEDIR"
  authd init "${CONST_NODE_NAME}${NODE_NUMBER}" -o --chain-id "$CHAINID" --home "$HOMEDIR"
}
 
 
 
# Function to update application configuration
function updateAppConfig() {
  sed -i '/minimum-gas-prices =/c\minimum-gas-prices = "0.0001mol"' "$HOMEDIR/config/app.toml"
  sed -i '/address = "0.0.0.0:8545"/c\address = "0.0.0.0:8545"' "$HOMEDIR/config/app.toml"
  sed -i '/ws-address = "127.0.0.1:8546"/c\ws-address = "0.0.0.0:8546"' "$HOMEDIR/config/app.toml"
  sed -i '/api = "eth,net,web3"/c\api = "eth,txpool,personal,net,debug,web3"' "$HOMEDIR/config/app.toml"
}
 
 
 
# Main execution
set -o xtrace
setupNode
copyGenesis
updateAppConfig
 
 
 
*****************************************

Swap Out the `genesis.json` File

In the /$HOMEDIR/config/ directory, you will find a genesis.json file. Replace the existing genesis.json file with the new version found in your cloned node repo.

Creating the Service File

Using your IDE of choice, create a new authd.service file using the following command:

sudo vim /etc/systemd/system/authd.service

Your authd.service file should contain the following code:

[Unit]
Description=Auth Daemon
After=network.target
 
 
 
[Service]
Type=simple
ExecStart=/bin/sh -c 'echo "Z3xV7aDp" | authd start --json-rpc.api=eth,txpool,personal,net,debug,web3 --api.enable --home YOUR_HOME-DIR'
WorkingDirectory=/home/<USER>
User=<USERNAME>
Group=<GROUP>
 
 
 
[Install]
WantedBy=multi-user.target

You must replace the following variables within this file:

<USER> - The name of your node's working directory.
<USERNAME> - Your username for node access.
<GROUP> - The name of your node group.

Running the Node Software

After completing the above configuration, you can run the node software with the following commands:

sudo systemctl enable authd.service
sudo systemctl start authd.service
