Update blockchain node

Use the following steps to update the blockchain node software, if you already have an older version installed.

Warning

This is blockchain software. Do not use on a computer or device with sensitive or important personal data. Using this software will require opening firewall ports. Using this software may result in heavy internet data usage. Use at your own risk.

Important

It is highly recommended to take a backup of your wallet keys before proceeding, to a different device.

  1. If the node is running, stop the existing node by pressing CTRL+C. If the node is not running, open the appropriate shell window.

    Windows
    Open Powershell
    Mac
    Open Terminal
    Linux
    Open Terminal
  2. Change to the folder dp.

    Windows
    cd c:\dp
    Mac
    cd $HOME/dp
    Linux
    cd $HOME/dp
  3. Download the updated CLI (command line interface) wallet by running the following command:

    Windows
    curl https://github.com/quantumcoinproject/quantum-coin-go/releases/download/v2.0.67/qc-release-windows-v2.0.67.zip -o qc-release-windows-v2.0.67.zip
    Mac
    curl -Lo qc-release-mac-v2.0.67.tar.gz https://github.com/quantumcoinproject/quantum-coin-go/releases/download/v2.0.67/qc-release-mac-v2.0.67.tar.gz
    Linux
    curl -Lo qc-release-ubuntu-v2.0.67.tar.gz https://github.com/quantumcoinproject/quantum-coin-go/releases/download/v2.0.67/qc-release-ubuntu-v2.0.67.tar.gz
  4. Extract the contents of the downloaded zip file to a folder.

    Windows
    Expand-Archive -Path qc-release-windows-v2.0.67.zip -DestinationPath c:\ -Force
    Mac
    tar -xzvf qc-release-mac-v2.0.67.tar.gz
    Linux
    tar -xzvf qc-release-ubuntu-v2.0.67.tar.gz
  5. This step is specific to Windows.

    Windows
    Close the Powershell window. Open a command prompt instead and change to the following folder.
    cd c:\dp
  6. This step is specific to Mac and Linux. Set the environment variable to the required library path. Remember that if you open a new Terminal window anytime, you will need to run this command again, to set the environment variable. You might want to add this environment variable to your shell profile.

    Mac
    export DYLD_LIBRARY_PATH=$HOME/dp
    Linux
    export LD_LIBRARY_PATH=$HOME/dp
  7. Run any other relevant command for connecting to mainnet or starting a validator node.

  8. To stop the blockchain node client, do not close the window or logout or shutdown directly. Instead press CTRL+C.
