Build and run the Groestlcoin Core 25.0 node with a graphical wallet

In continuation to the article Building from source and run a Groestlcoin node (cli only) under Ubuntu 22.04 LTS, which offers only a command line management to the Groestlcoin wallets, this article will show a more convenient way with a graphical user interface. Groistlcoin Core software includes a graphical user interface for the Groestlcoin wallet.

The first thing is to build the Groestlcoin Core software as shown in the link above with some additional dependencies and options.
It’s worth noting there is a package for the graphical Groestlcoin wallet on the official site of Groestlcoin, but the idea behind this series of articles is to build everything from the official source code and to run an own Groestlcoin node, which will be used for the user’s Groestlcoin wallet. Such no trusting anyone or any site, but only the official source code of the project. The security is really important in the crypto world.

Here are the steps to build and run the Groestlcoin node with wallet functionality – command line and graphical user interface. The graphical user interface uses QT5 to build the wallet interface and all libraries are included in the official Ubuntu repositories.

STEP 1) Build and run the Groestlcoin node

For more detailed information check out Building from source and run a Groestlcoin node (cli only) under Ubuntu 22.04 LTS.

First, install the dependencies but with additional libraries including the QT5 and qrencode. Update the system and install the needed additional binaries and libraries to build and run the Groestlcoin core package. These dependencies include the ones needed to build the Groestcoin wallet functionality with GUI! By default, many Linux systems won’t even include dependencies needed to build the wallet.

sudo apt -y update
sudo apt -y upgrade
sudo apt install build-essential libssl-dev libboost-all-dev libtool automake libevent-dev bsdmainutils git make g++ gcc autoconf cpp ngrep iftop sysstat autotools-dev pkg-config libminiupnpc-dev libzmq3-dev libdb-dev libdb5.3++-dev sqlite3 libsqlite3-dev

Generate a new Groestlcoin address (wallet) and list wallets and addresses using command line cli verson 25.0.0

This article an updated version of Generate a new Groestlcoin address (wallet) and list accounts and addresses, because it appeared many things handling the wallets and address with the command-line have changed.

main menu
new wallet and address

The generation of a new Groestlcoin address is relatively simple, just use the command line tool – groestlcoin-cli, which is a Groestlcoin Core RPC client talking to the Groestlcoin node. So a working and synchronized Groestlcoin node is needed. Check out Building from source and run a Groestlcoin node (cli only) under Ubuntu 22.04 LTS for more information how to build and run a Groestlcoin node.

DO NOT TRUST any online website or any other Internet source to generate your Groestlcoin wallet address for you. DO IT YOURSELF with the official software from the official site!
If the user followed the above link to build and run a Groestlcoin and has waited to synchronize, it is time to use the groestlcoin-cli to create a wallet and then generate addresses. In fact, the wallet contains Groestlcoin addresses and it may be encrypted for better security. The Groestlcoin node is running and synchronized.

STEP 1) Create a new or load an old Groestlcoin wallet.

There is no default wallet and no wallet is loaded automatically on start, by default (indeed a wallet may be automatically loaded, but it should be specified on loading).
List all the Groestlcoin wallets under the current user:

myuser@mydesktop:~$ cd groestlcoin-core/bin/
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli listwallets
[
]
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli listwalletdir
{
  "wallets": [
  ]
}
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli listaddressgroupings
error code: -18
error message:
No wallet is loaded. Load a wallet using loadwallet or create a new one with createwallet. (Note: A default wallet is no longer automatically created)

Apparently, there are no wallets, so here is how to create a wallet:
Create a wallet with:

myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli createwallet my-groestlcoin-wallet
{
  "name": "my-groestlcoin-wallet"
}
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli encryptwallet 'joo8laeW9Chietae&phu'
wallet encrypted; The keypool has been flushed and a new HD seed was generated (if you are using HD). You need to make a new backup.

When creating one wallet, it will become the default one, and all commands on groestlcoin-cli will use it. To specify exactly the name of the wallet with the command, the option “-rpcwallet=” should be used. In general, with one wallet there is no need to specify the wallet name, but when there are two or more loaded wallets, it is mandatory to specify with “-rpcwallet=” the wallet name.
Creating one more wallet with groestlcoin-cli will result in two loaded wallets, so after that, all commands should include “-rpcwallet=”.

myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli createwallet my-groestlcoin-wallet-2
{
  "name": "my-groestlcoin-wallet-2"
}
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli -rpcwallet="my-groestlcoin-wallet-2" encryptwallet "ief0ahshao8ca8Dai-ng"
wallet encrypted; The keypool has been flushed and a new HD seed was generated (if you are using HD). You need to make a new backup.

Building from source and run a Groestlcoin node (cli only) under Ubuntu 22.04 LTS

It was a bit while after the Building from source a Groestlcoin node (cli only) under Ubuntu 16 LTS. So after 6 years is it the same procedure or there are additional or simplified steps (to build) and run a cryptocurrency Groestlcoin node? The GRS price seems the same as it was 6 years ago, but there are some new things in the software.

main menu
groestlcoin-cli getblockchaininfo

The first step is to build the software and it is one of the most important steps – download the source code ONLY from the official source, check the official site https://www.groestlcoin.org/groestlcoin-core-wallet/ where the source code could be downloaded or to see where is the official place for the source code – https://github.com/Groestlcoin/groestlcoin. Check the links yourself! The https://github.com/Groestlcoin/groestlcoin git link will be used to download the latest stable version of the code and to build a Groestlcoin node, which may or may not include wallet capabilities. Building the Groestlcoin core package from the source you’ll have your private and secure Groestlcoin node (and wallet), which could be used to make secure transactions and receive funds in the Groestlcoin network and a lot more! DO IT YOURSELF – the most secure way of generating a Groestlcoin wallet address, making transactions such as sending and receiving coins, and storing your wallets.

STEP 1) Update your system and install dependencies

Update your system and install the needed additional binaries and libraries to build and run the Groestlcoin core package. These dependencies include the ones needed to build the Groestcoin wallet functionality! By default, many Linux systems won’t include dependencies needed to build the wallet.

sudo apt install groestlcoin dependencies
