1. Environment Preparation

• Install the required dependencies, including Go. Remove any previous versions and install the new version:

  sudo rm -rf /usr/local/go
  sudo tar -C /usr/local -xzf go$ver.linux-amd64.tar.gz
  echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
  source $HOME/.bash_profile
  
  

2. Download and Install Binaries

• Download the junctiond binary, make it executable, and move it to /usr/local/bin:

  wget <https://github.com/airchains-network/junction/releases/download/v0.1.0/junctiond>
  chmod +x junctiond
  sudo mv junctiond /usr/local/bin
  
  

3. Node Initialization

• Configure the node:

  junctiond config chain-id junction
  junctiond init "Moniker" --chain-id junction
  
  

4. Download Configuration Files

• Download the genesis.json and addrbook.json files for your node:

  wget -O $HOME/.junction/config/genesis.json <https://raw.githubusercontent.com/airchains-network/props/main/Airchains/genesis.json>
  wget -O $HOME/.junction/config/addrbook.json <https://raw.githubusercontent.com/airchains-network/props/main/Airchains/addrbook.json>
  
  

5. Set Up Service and Start Node

• Create a systemd service file for automatic node startup:

  sudo tee /etc/systemd/system/junctiond.service > /dev/null <<EOF
  [Unit]
  Description=Airchain Validator Node
  After=network-online.target
  
  [Service]
  User=$USER
  ExecStart=$(which junctiond) start
  Restart=always
  RestartSec=3
  LimitNOFILE=65535
  
  [Install]
  WantedBy=multi-user.target
  EOF
  sudo systemctl daemon-reload
  sudo systemctl enable junctiond
  sudo systemctl start junctiond
  
  

• Check the logs to verify the status:

  sudo journalctl -u junctiond -f --no-hostname -o cat
  
  

6. Create Validator

• Get your validator's public key:

  junctiond comet show-validator
  
  

• Create a JSON file for your validator: Fill the file with your public key and other details:

  nano $HOME/validator.json
  
  

  {
     "pubkey": "<validator-pub-key>",
     "amount": "1000000amf",
     "moniker": "<validator-name>",
     "identity": "<optional-identity>",
     "website": "<optional-website>",
     "security": "<optional-security>",
     "details": "<optional-details>",
     "commission-rate": "0.1",
     "commission-max-rate": "0.2",
     "commission-max-change-rate": "0.01",
     "min-self-delegation": "1"
  }
  
  

• Create the validator using the following command:

  junctiond tx staking create-validator $HOME/validator.json --from <wallet-name> --chain-id junction --fees 5000amf
