# You can now run a full node. If you want to farm you must first create a
# plot. Assuming you have 360 GB free in ~/plotstmp and 102 GB in ~/plots, you
# can create your first plot as follows:
mkdir ~/plotstmp ~/plots
chia plots create -t ~/plotstmp -d ~/plots
# Note that this may take more than 10 hours.

GUI Build / Usage

WARNING: the following has not been tested on OpenBSD 6.8

The build instructions in the previous sections above must be completed successfully before attempting to build the GUI using the procedure below.

WARNING: Although the following steps have been used successfully, the resulting GUI will be run with an older version of electron than is recommended by the Chia Network team. This may result in unexpected problems.

Prerequisite package installation

As root (or using doas / sudo), first install some additional OpenBSD packages required for GUI usage:

pkg_add -i electron

Build

cd chia-blockchain
. ./activate

cd chia-blockchain-gui

# build / set up GUI
npm run build

# Remove failed electron 8.2.5 install and fall back to the OpenBSD
# ports tree 8.2.0 electron, which currently (as of 6/10/2020) works.
#
# This may not continue to work in the future.  A full solution to
# this requires official OpenBSD electron builds, provided by the
# electron project itself.

rm -rf node_modules/electron

Launch GUI

The GUI can now be launched using the following commands:

cd chia-blockchain
. ./activate

cd chia-blockchain-gui
npm run electron
