Monero (XMR) is a decentralized digital currency with a very high degree of user privacy. It has a obfuscated blockchain which makes it very hard to tell the source, destination or amount of any given transaction. New Monero currency is generated using a proof of work mining algorithm. The algorithm has been changed several times. It is currently mined using the randomX algorithm.
The Monero network daemon and the Monero wallet GUI are free software under the The 3-clause BSD license.
Monero has not gained much popularity among online retail stores since it was released on April 18th, 2014. It has gained some limited popularity on dark net web stores due to the built-in privacy properties that are very attractive amount a certain type of merchants.
A limited number of the larger crypto currency exchanges like Bitfinex, Kraken and Bittrex have Monero XMR currency pairs. Most larger notable exchanges such as Bitstamp and Coinbase do not have any XMR pairs available for trading.
Installing The Monero Wallet
The graphical Monero wallet, available from web.getmonero.org/downloads/, allows you to store, receive and send Monero XMR currency. It is quite easy to use. The file offered for GNU/Linux includes a statically compiled Monero daemon binary called
monerod and an AppImage binary called
monero-wallet-gui. These are the only files from the archive you need to use the wallet. You can copy
monero-wallet-gui from the wallet gui archive to a place in your system
$PATH such as
/usr/local/bin to make the binaries you need to run the wallet available. The
monerod will be started by the wallet when it is executed and stopped when it is closed.
monero-wallet-gui binary will infect your
$HOME with an icon and a
monero-gui.desktop file adding Monero to the systems menu
$HOME/.local/share/applications/ the first time you run it. You will want to change the default
Exec=monero-wallet-gui %u line in that
monero-gui.desktop file to:
Exec=env QT_AUTO_SCREEN_SCALE_FACTOR=1 monero-wallet-gui %u
This is because the wallet GUI is a Qt application capable of scaling to the right size on high resolution monitors. It will only do that if a QT_AUTO_SCREEN_SCALE_FACTOR environment variable is set to 1. That variable will likely be unset; you can open a terminal and
echo $QT_AUTO_SCREEN_SCALE_FACTOR to see if your the desktop environment and/or GNU/Linux distributions gives it a value.
You will likely also want to change the icon defined in the
monero-gui.desktop file. The wallet gui archive does not include an icon file and the Papirus theme and the classic-kde-remixed themes come with an icon that is actually named
monero. Icons like
format-currency (most KDE focused themes have it) or
accessories-calculator may be preferable if
Icon=monero results in no icon or a default icon on your system.
Using The Monero Wallet
Using the wallet is easy once you have it installed. It takes some time from you start it to the time it is ready to be used because it needs to start the
monerod monero daemon to connect to the network. The Monero Wallet GUI will present a easy to use interface once that is done. The left side will have your with an overview of your Primary, and optionally, secondary accounts. There is also , , and .
Thetab lets you create addresses other people can send to. A QR-Code will be shown for selected addressed. This QR-Code can be saved as an image if you want to send it to someone or place it on a web page.
The wallet GUI is overall very easy to use if you want to send and receive digital Monero XMR currency.
The XMRig mining program is the best option for mining Monero XMR currency on GNU/Linux machines. It is also available for other platforms like Windows and macOS.
The randomX algorithm Monero uses does not benefit from GPU mining. It can be done but the cost per hash is higher than the cost of mining using a CPU. The GPU mining code in XMRig is geared towards CUDA mining on NVidia graphics cards and the proprietary AMD graphics driver for Windows. It does not work with the AMD ROCm OpenCL driver which is otherwise the best option for doing OpenCL on AMD graphics cards.
The Monero software can be acquired from web.getmonero.org/downloads.
