Frequently Asked Questions (FAQ)

Q: How do I run a node on Linux?

• git clone https://github.com/vfcash/VFC-Core && cd VFC-Core
• chmod 0777 compile.sh
• sudo ./compile.sh
• vfc cdn_resync
• Install(s) to /usr/bin/vfc
• Ensure you have the UDP Port 8787 forwarded.
• Run "vfc mine" and earn some VFC to register your node on the network.
• Make sure you run compile.sh as root, for example: sudo ./compile.sh
• If you are behind a router, make sure you have UDP port 8787 forwarded to the correct local IP address on your network.
• If you are in China, you will find that you may have your internet connection dropped periodically due to the use of UDP.
• Please ensure you have an IPv4 address.

Q: I am a Linux user and I don’t want to run a node. Can I still mine offline?

• You do not need to run a local node to mine and claim VFC rewards to your rewards address. However, it is highly suggested you run a node so that you are not limited by the restrictions on the REST API.
• If you are mining offline with Linux, you can claim your mined VFC rewards by entering "vfc claim" into the console, or to see your unclaimed addresses use "vfc unclaimed".
• To launch the miner enter "vfc mine" into the console.

Q: I am a Windows or Mac user. Can I still mine VFC?

• Yes, you can! Please use the Portable nativeMiner here and the Portable nativeWallet here.
• You can compile the Linux node to run on Windows 10. Please refer to https://docs.microsoft.com/en-us/windows/wsl/install-win10 in order to set up the Ubuntu console, otherwise, you will need to run a VM such as https://www.virtualbox.org/wiki/Downloads.

Q: I see that I have unclaimed rewards. How do I claim them?

• You can claim your mined VFC rewards by entering "vfc claim" into the console, or to see your unclaimed addresses use "vfc unclaimed".
• Your data directory is located at ~/.vfc/. You can change this by setting the Environment Variable VFCDIR to a custom directory path.
• Your reward address private key is located in ~/.vfc/private.key. This is all you need to perform a backup.
• Your minted private keys are located in ~/.vfc/minted.priv

Q: I am still confused. Is there a Help command?

• Once you are up and running, you just need to enter the command "vfc help" into the console.
