Installation f(x)Core

This guide will explain how to install the fxcored CLI onto your system. With this installed on a server, you can participate on the mainnet as either a Full Node or a Validator.
Additionally, you may refer to this YouTube tutorial video to set up your validator.

Hardware Requirements

We recommend the following for running f(x)Core:
  • 4 or more CPU cores
  • At least 500G of disk storage
  • At least 8G of memory
  • At least 10mbps network bandwidth
To see a quick cloud setup on how to setup and deploy it on the cloud.

Install build requirements

Install make and gcc.
On Ubuntu this can be done with the following commands:
sudo apt-get update
sudo apt-get install -y make gcc
Ps: sudo apt-get install -y make gcc may have encountered a problem with locked files, just try sudo apt-get install -y make gcc again.
Ensure you have Homebrew installed.
Once you have Homebrew installed, you may run the following commands to install make :
brew install make
and gcc:
brew install gcc
We'll be needing these commands later so let's install the necessary packages:
brew install git
brew install wget
You will need to run git bash. You may find the installation link here.
Ensure you have make and gcc installed and that the paths are set correctly for git bash.
One option for installing gcc can be found here.
You may select tdm64-gcc-10.3.0-2
Restart gitbash after installing
One option for installing make is using chocolate , more information can be found here.
Once you have chocolate installed, run this command:
make sure to run gitbash as administrator mode if the following commands do not work
choco install make
Ensure you have all the necessary dependencies and compilers.
gcc --version
will return:
gcc.exe (tdm64-1) 10.3.0

If you are remoting into a terminal
Install go by following the official docs. Please select your respective environment❗
For Ubuntu environment, there may be permissions denied issues with unzipping the go zip file, try using sudo su to resolve it.
Especially if you are remoting into a Ubuntu terminal, run this command to download the go installer:

After you have downloaded the package and you may proceed to step 2 of the official docs. Choose your system OS and follow the instructions stated.
Go 1.19+ or later is required for the f(x)Core. If you are remoting into a terminal, you may input the following command:
Setting environment variables:
mkdir -p $HOME/go/bin
echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.profile
echo "export PATH=$PATH:$(go env GOPATH)/bin" >> ~/.profile
source ~/.profile

Install the binaries

Next, let's install the latest version of f(x)Core. Make sure you have git installed if not you will be prompted to install git. Follow the instruction in the terminal.
git clone --branch release/v3.1.x
cd fx-core
git clone --branch release/v3.1.x
cd fx-core
You should run your commands in gitbash. But open fxcored.exe file using cmd prompt
Make sure the name of your folder does not have whitespaces!
git clone --branch release/v3.1.x
cd fx-core
You may find the latest branches here:
All Other Environments
make go.sum
make install
make go.sum
make build-win
use cmd prompt to open the fxcored.exe file
in the path ./build/bin/fxcored.exe
That will install the fxcored binary. Verify version:
