Send and receive Groestlcoins with Groestlcoin Core 25.0 graphical user interface

As a continuation of managing Groestlcoin wallet articles Send coins in Groestlcoin network from command line with Groestlcoin Core 25 in year 2023, Build and run the Groestlcoin Core 25.0 node with a graphical wallet and Generate a new Groestlcoin address (wallet) and list wallets and addresses using command line cli verson 25.0.0. This article will show how to transfer Groestlcoins with the official Groestlcoin Core desktop application and the look and feel of the wallet functionality of the Groestlcoin Core.

Overview balances

The basic topics to manage a Groestlcoin wallet with the official software (ALWAYS use only official software) are:

  • Groestlcoin Core provides two key functionalities – become a Groestlcoin node, i.e. a part of the Groestlcoin network and the Groestlcoin wallet with command line interface and graphical user interface.
  • Groestlcoin Core can generate and Groestlcoin address.
  • a Groestlcoin wallet contains Groestlcoin addresses.
  • the Groestlcoin Core has a wallet functionality application, but before using it the wallet needs to synchronize with the Groestlcoin network. So the Groestlcoin GUI application will start a Groeslcoin node and it will try synchronizing with the network.
  • Groestlcoin Core includes groestlcoin-qt application, which offers the graphical user interface
  • Using groestlcoin-qt is really simple to manage wallets, generate Groestlcoin addresses, and get information for the local Groestlcoin node, which is used by the wallet application.

Here are the steps needed to transfer funds under the Linux distro of Ubuntu securely, but this time from the Gnome. To be able to transfer money securely without any 3rd party involved (no online wallet or wallets, which is unclear which node they connect to) just funds from your personal Groestlcoin wallet address on your computer to another Groestlcoin wallet address it is needed a running Groestlcoin node using Groestlcoin Core graphical user interface:groestlcoin-qt – this application provides basic graphical user interface for managing the Groestlcoin wallets. After the Groestlcoin Core is build and installed (check this article – Build and run the Groestlcoin Core 25.0 node with a graphical wallet), start the /[user_home_directory]/groestlcoin-core/bin/groestlcoin-qt. Apparently, the Groestlcoin site offers a compiled version of Groestlcoin Core (with an installer for Windows, too), but be careful what you download and from where! The best way is to just follow our article to build it yourself under Ubuntu.

SCREENSHOT 1) The loading screen at the start of groestlcoin-qt application.

It may take time to start because it is loading the local cached block index and if the node was fully synced lately, it may take a minute or two to load.

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.

node window synced with network

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

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.

main menu
sudo apt install groestlcoin dependencies

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

Running a Electroneum node from source under Ubuntu 16 LTS

This howto is made to show you how to run a Electroneum node. To run a Electroneum node we need the official electroneum daemon software:

electroneumd

which will start and wait for the network synchronization – our Electroneum node will receive all the blockchains of the network!
Installing (or compiling it) the Electroneum software of the official site will ensure you have the right software for generating and sending/receiving transactions securely and privately! Always use your node software for generating the Electroneum wallet address, DO NOT TRUST any sites, which offer you a creation of Electroneum wallet or any other crypto currency. In crypto world the one how controls the private key of the wallet (which is generated with the creation of the wallet) controls the Electroneum wallet address so controls your funds! Just Install or compile a Electroneum node software – Building from source a Electroneum node under Ubuntu 16 LTS and you’ll everything you need to manage your Electroneum funds!
It’s worth mentioning again this section of Electroneum node howto (if you read other howtos for running a node you would probably read it, but it so important we include it in every howto!!!):
And also be warned DO NOT use insecure sources when:

  1. installing Ubuntu, install it from a cd/dvd/usb downloaded from the official Ubuntu site here.
  2. installing all the needed dependencies from official sources only, not recommended the PPA reposigories, neither!
  3. install yourself the “electroneumd” program (the official Electroneum software), which will create a Electroneum node and after network synchronization could be used to create a Electroneum node.

Three simple rules could almost eliminate leaking your private key to hackers, which in blockchain world means losing your money…
And before start the installation a performance advice:

USE SSD

Technically with Electroneum node you can still use hard drive, but it is slow, but not impossible as some of the older crypto currencies like Ethereum, Bitcoin, Monero and so on.

STEP 1) Install Ubuntu 16 – our howto will be available soon here.

STEP 2) Building from source a Electroneum node

Check out our howto “Building from source a Electroneum node under Ubuntu 16 LTS“.

STEP 3) Start the Electroneum node

if you have followed the howto in STEP 2) you probably have “electroneumd” installed in “~/electroneum/build/release/bin”, so run it with:

ubuntu@srv.local:~/electroneum/build/release/bin$ ./electroneumd &> ./electroneumd.log

It is a good practice to run it with screen and in an infinite loop – if the program crashes it will start automatically and you’ll always have a synchronized node, of course, if you do not need a Electroneum node running all the time the infinite loop is not needed. The user could just start the node, wait for synchronization and then make your transactions and stop the node, after several days you can start it up the catching up the synchronization won’t take much time:

ubuntu@srv.local:~$ screen -R electroneum
ubuntu@srv.local:~$ cd electroneum/build/release/bin
ubuntu@srv.local:~/electroneum/build/release/bin$ while true; do ./electroneumd &> ./electroneumd.log;done

STEP 3) Wait for the blockchain network synchronization

This step could take significant amount of time, server resources and network bandwidth! USE SSD(s) for your home directory, because the blockchain database will be saved at your

home directory/.electroneum/

If you want to move it on another server or directory (or device) you must copy this directory to the new location.
The generated IO is so extensive that for a traditional hard drive probably will be difficult to catch up with the synchronization.
When you run “electroneumd” it will check the current state of the network and the current state of your Electroneum node, so no matter it is started for the first time or not a network synchronization is needed, your node need to be synchronized with the Electroneum network to be used for all kind of actions in the network (create a wallet, transfer funds and more).
Here is the output of just started Electroneum node:

There is also a log of all the output of the “electroneumd” under the “~/.electroneum/electroneum.log”.

“~/.electroneum/” is where all the data will be saved for the Electroneum node

You can see when your Electroneum node is fully synchronized and you may use the “electroneum-wallet-cli”.

As you can see we redirected the output of the program in a file in the same directory as “electroneumd”. The default output is informative here is what we can see about the blockchain syncronization:

  • how many blockchains we are behind the Electroneum network – “Sync data returned a new top block candidate: 1401 -> 255582”
  • how many days we are behind the Electroneum network – “Your node is 254181 blocks (176 days) behind”

At present with SSD and 16G RAM on a intel i7 processor and a fast Internet connection 100Mbps the full synchronization took about 12 hours and 18G of storage space.
After a successful full synchronization, in the log you’ll have:

You are now synchronized with the network.

and you are ready to use “electroneum-wallet-cli” or the others program to manage your funds – for example send, receive, check balance of your funds.
If you stop and start the program it will start the synchronization from the point you stopped.

Building from source a Electroneum node under Ubuntu 16 LTS

The program, which makes an Electroneum node from your computer, is called

electroneumd

You need a electroneum node to send, receive coins securely and privately and to maintain your wallet personally. DO IT YOURSELF – the most secure way of generating a electroneum wallet address and making transactions such as send and receive coins. As you usual here you’ll see: do not trust any site for generating an electroneum wallet address, use the official tools from this package to generate your addresses and to send and receive coins!
Sometimes you’ll see an easy way of installing the node such as a snap package or docker imagedo not trust them! Most of the time they are unofficial releases or 3rd party releases – trust only to the official site and repository all other packages our there bring more risk than features.

STEP 1) Update your system and install dependencies

sudo apt-get update -y
sudo apt-get -y upgrade
sudo apt-get install -y build-essential cmake pkg-config libboost-all-dev libssl-dev libunbound-dev libminiupnpc-dev libunwind8-dev liblzma-dev libldns-dev libexpat1-dev libgtest-dev doxygen graphviz

STEP 2) Get the “electroneumd” code and compile it

You could change to stable release (probably the last tag) if you like.

git clone https://github.com/electroneum/electroneum
cd electroneum
export CFLAGS="-march=native -O2 -msse3 -fomit-frame-pointer -pipe"
export CXXFLAGS="${CFLAGS}"
export CHOST="x86_64-pc-linux-gnu"
make

STEP 3) Check is everything is OK, installed electroneumd – Electroneum ‘Helium Hydra’

ls command shows the additional programs in the package.

srv@local:~/electroneum$ cd ./build/release/bin
srv@local:~/electroneum/build/release/bin$ ./electroneumd --version
Electroneum 'Helium Hydra' (v0.11.1.0-6a0535e)
srv@local:~/electroneum/build/release/bin$ ls 
electroneum-blockchain-export  electroneum-blockchain-import  electroneum-wallet-cli  electroneum-wallet-rpc  electroneumd

Most used programs are electroneumd and electroneum-wallet-cli, which offers a command line management of a electroneum wallet addresses.

Running a Groestlcoin node (wallet cli) from source under Ubuntu 16 LTS

This howto is made to show you how to run a full Groestlcoin node. To run a Groestlcoin node we need the official Groestlcoin daemon software:

groestlcoind

from the Groestlcoin Core package: https://www.groestlcoin.org/groestlcoin-core-wallet/ This program will start and wait for the network synchronization – our Groestlcoin node will receive all the blockchains of the network!
Installing (or compiling it) the Groestlcoin Core software of the official site will ensure you have the right software for generating and sending/receiving transactions securely and privately! Always use your node software for generating the Groestlcoin wallet address, DO NOT TRUST any sites, which offer you a creation of Groestlcoin wallet. In crypto world the one how controls the private key of the wallet (which is generated with the creation of the wallet) controls the Groestlcoin wallet address so controls your funds! It is so important that we repeat it in EVERY cryptocurrency howto! Just Install or compile a Groestlcoin Core node software – Running a Groestlcoin node (cli) from source under Ubuntu 16 LTS and you’ll everything you need to manage your Groestlcoin funds!
It’s worth mentioning again this section of Groestlcoin (Wallet) node howto:
And also be warned DO NOT use insecure sources when:

  1. installing Ubuntu, install it from a cd/dvd/usb downloaded from the official Ubuntu site here.
  2. installing all the needed dependencies from official sources only, not recommended the PPA reposigories, neither!
  3. install yourself the “groestlcoind” program (the official Groestlcoin software), which will create an Groestlcoin node and after network synchronization could be used to create an Groestlcoin node.

Three simple rules could almost eliminate leaking your private key to hackers, which in blockchain world means losing your money…

With Groestlcoin you can still use ordinary hard drive, but it will be much slower than SSDs.

USE SSD

STEP 1) Install Ubuntu 16 – our howto will be available soon here.

STEP 2) Building from source an Groestlcoin (Wallet) node

Check out our howto “Running a Groestlcoin node (cli) from source under Ubuntu 16 LTS“.

STEP 3) Start the Groestlcoin node

if you have followed the howto in STEP 2) you probably have “groestlcoind” installed in “~/groestlcoin-core/bin”, so run it with:

ubuntu@srv.local:~/groestlcoin-core/bin$ ./groestlcoind &> ./groestlcoind.log

It is a good practice to run it with screen and in an infinite loop – if the program crashes it will start automatically and you’ll always have a synchronized node, of course, if you do not need a Groestlcoin (wallet) node running all the time the infinite loop is not needed. The user could just start the node, wait for synchronization and then make your transactions and stop the node, after several days you can start it up the catching up the synchronization won’t take much time:

ubuntu@srv.local:~$ screen -R groestlcoin
ubuntu@srv.local:~$ cd groestlcoin-core/bin/
ubuntu@srv.local:~/groestlcoin-core/bin$ while true; do ./groestlcoind &> ./groestlcoind.log;done

STEP 3) Wait for the blockchain network synchronization

This step could take significant amount of time, server resources and network bandwidth! USE SSD(s) for your home directory, because the blockchain database will be saved at your

home directory/.groestlcoin/

If you want to move it on another server or directory (or device) you must copy this directory to the new location.
When you run “groestlcoind” it will check the current state of the network and the current state of your groestlcoin (wallet) node, so no matter it is started for the first time or not a network synchronization is needed, your node need to be synchronized with the groestlcoin network to be used for all kind of actions in the network (create a wallet, transfer funds and more).
Here is the “~/.groestlcoin” direcotry:

srv@local:~$ ls -altr .groestlcoin/

You can see we are at 1592616 of total 2020535. When “blocks” count equalize with the “headers” your Groestlcoin (wallet) node is synchronized successfully and the debug.log will just only output a couple of lines every minutes:

The starting date of the line will differ with couple of seconds of the date in the transaction – the “date=” after the “tx=”.
Now you can start using your Groestlcoin (wallet) node for transactions and

At present with SSD and 16G RAM on a intel i7 processor and a fast Internet connection 100Mbps the full synchronization took about 40 minutes and 2G of storage space.
You are ready to use “groestlcoin-cli” or the others program to manage your funds – for example send, receive, check balance of your funds.
If you stop and start the program it will start the synchronization from the point you stopped.

Building from source a Groestlcoin node (cli only) under Ubuntu 16 LTS

The program, which makes an Groestlcoin node in your computer, is called

groestlcoind

and is part of the official package named

Groestlcoin Core

It includes the full capabilities of Groestlcoin wallet and a private Groestlcoin node. Building it from the source you’ll have your private and secure Groestlcoin, which could be used to make secure transactions and receive funds in Groestlcoin network and a lot more! DO IT YOURSELF – the most secure way of generating a Groestlcoin wallet address, making transactions such as send and receive coins and storing your wallets.

STEP 1) Update your system and install dependencies

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

STEP 2) Get the “Groestlcoin Core” code and compile it

You could change to stable release (probably the last tag) if you like.

git clone https://github.com/groestlcoin/groestlcoin
cd groestlcoin
export CFLAGS="-march=native -O2 -msse3 -fomit-frame-pointer -pipe"
export CXXFLAGS="${CFLAGS}"
export CHOST="x86_64-pc-linux-gnu"
./autogen.sh
./configure --prefix=/home/ubuntu/groestlcoin-core
make -j 8
make install

The above example assumes your home directory is “/home/ubuntu/” (the username of ubuntu), replace “/home/ubuntu/” with the directory where you want to install or the simplest way is to check your home directory and use it – “/home/[user_home_directory]/groestlcoin-core”. When compiled and installed the applications from the “Groestlcoin Core” package will be installed in “/home/[user_home_directory]/groestlcoin-core” or in our case “/home/ubuntu/groestlcoin-core”

STEP 3) Check is everything is OK

ls command shows the additional programs in the package.

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the ' -D__LIBTOOL_IS_A_FOOL__ ' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

Running a Monero node from source under Ubuntu 16 LTS

This howto is made to show you how to run a Monero node. To run a Monero node we need the official monero daemon software:

monerod

This program will start and wait for the network synchronization – our Monero node will receive all the blockchains of the network!
Installing (or compiling it) the Monero software of the official site will ensure you have the right software for generating and sending/receiving transactions securely and privately! Always use your node software for generating the Monero wallet address, DO NOT TRUST any sites, which offer you a creation of Monero wallet. In crypto world the one how controls the private key of the wallet (which is generated with the creation of the wallet) controls the Monero wallet address so controls your funds! Just Install or compile a Monero node software – Building from source a Monero node under Ubuntu 16 LTS and you’ll everything you need to manage your Monero funds!
It’s worth mentioning again this section of Monero node howto:
And also be warned DO NOT use insecure sources when:

  1. installing Ubuntu, install it from a cd/dvd/usb downloaded from the official Ubuntu site here.
  2. installing all the needed dependencies from official sources only, not recommended the PPA reposigories, neither!
  3. install yourself the “monerod” program (the official Monero software), which will create a Monero node and after network synchronization could be used to create a Monero node.

Three simple rules could almost eliminate leaking your private key to hackers, which in blockchain world means losing your money…
And before start the installation a performance advice do not attempt to run a Monero node in a hard disk –

USE SSD

If you use a hard disk even in RAID configuration it could take several days for network synchronization and probably your machine will be useless during the synchronization.

STEP 1) Install Ubuntu 16 – our howto will be available soon here.

STEP 2) Building from source a Monero node

Check out our howto “Building from source a Monero node under Ubuntu 16 LTS“.

STEP 3) Start the Monero node

if you have followed the howto in STEP 2) you probably have “monerod” installed in “~/monero/build/release/bin”, so run it with:

ubuntu@srv.local:~/monero/build/release/bin$ ./monerod &> ./monerod.log

It is a good practice to run it with screen and in an infinite loop – if the program crashes it will start automatically and you’ll always have a synchronized node, of course, if you do not need a Monero node running all the time the infinite loop is not needed. The user could just start the node, wait for synchronization and then make your transactions and stop the node, after several days you can start it up the catching up the synchronization won’t take much time:

ubuntu@srv.local:~$ screen -R monero
ubuntu@srv.local:~$ cd monero/build/release/bin
ubuntu@srv.local:~/monero/build/release/bin$ while true; do ./monerod &> ./monerod.log;done

STEP 3) Wait for the blockchain network synchronization

This step could take significant amount of time, server resources and network bandwidth! USE SSD(s) for your home directory, because the blockchain database will be saved at your

home directory/.bitmonero/

If you want to move it on another server or directory (or device) you must copy this directory to the new location.
The generated IO is so extensive that a traditional hard drive probably will not be able to catch up with the synchronization.
When you run “monerod” it will check the current state of the network and the current state of your Monero node, so no matter it is started for the first time or not a network synchronization is needed, your node need to be synchronized with the Monero network to be used for all kind of actions in the network (create a wallet, transfer funds and more).
Here is the output of just started Monero node:

**********************************************************************
You are now synchronized with the network. You may now start monero-wallet-cli.

Use the "help" command to see the list of available commands.
**********************************************************************

As you can see we redirected the output of the program in a file in the same directory as “monerod”. The default output is informative here is what we can see about the blockchain syncronization:

  • how many blockchains we are behind the Monero network – “Synced 101/1529571”
  • how many days we are behind the Monero network – “Your node is 1529570 blocks (1422 days) behind”

At present with SSD and 16G RAM on a intel i7 processor and a fast Internet connection 100Mbps the full synchronization took about 12 hours and 47G of storage space.
After a successful full synchronization, in the log you’ll have:

You are now synchronized with the network.

and you are ready to use “monero-wallet-cli” or the others program to manage your funds – for example send, receive, check balance of your funds.
If you stop and start the program it will start the synchronization from the point you stopped.

Building from source a Monero node under Ubuntu 16 LTS

The program, which makes an Monero node in your computer, is called

monerod

You need a monero node to send and receive coins securely and privately. DO IT YOURSELF – the most secure way of generating a monero wallet address and making transactions such as send and receive coins.
Sometimes you’ll see an easy way of installing the node such as a snap package or docker imagedo not trust them! Most of the time they are unofficial releases or 3rd party releases – trust only to the official site and repository all other packages our there bring more risk than features.

STEP 1) Update your system and install dependencies

sudo apt-get update -y
sudo apt-get -y upgrade
sudo apt-get install -y build-essential cmake pkg-config libboost-all-dev libssl-dev libzmq3-dev libunbound-dev libsodium-dev libminiupnpc-dev libunwind8-dev liblzma-dev libreadline6-dev libldns-dev libexpat1-dev libgtest-dev doxygen graphviz

STEP 2) Get the “monerod” code and compile it

You could change to stable release (probably the last tag) if you like.

git clone https://github.com/monero-project/monero
cd monero
export CFLAGS="-march=native -O2 -msse3 -fomit-frame-pointer -pipe"
export CXXFLAGS="${CFLAGS}"
export CHOST="x86_64-pc-linux-gnu"
make

STEP 3) Check is everything is OK, installed monerod – Monero ‘Helium Hydra’

ls command shows the additional programs in the package.

srv@local:~/monero$ cd ./build/release/bin
srv@local:~/monero/build/release/bin$ ./monerod --version
Monero 'Helium Hydra' (v0.11.1.0-master-a03d34f)
srv@local:~/monero/build/release/bin$ ls 
monero-blockchain-export  monero-blockchain-import  monerod  monero-gen-trusted-multisig  monero-wallet-cli  monero-wallet-rpc

Most used programs are monerod and monero-wallet-cli, which offers a command line management of a monero wallet addresses.

* Here is the help output of “monerod” – the Monero node daemon:

Running an Ethereum node from source under Ubuntu 16 LTS

This howto is made to show you how to run an Ethereum node. To run an Ethereum node we need the

geth

program to start and wait for the network synchronization – our Ethereum node will receive all the blockchains of the network!
After a successful Ethereum network synchronization we can send and receive coins securely ourselves! No other online service offers us secure sending and receiving of transcations and creation of wallet, the only way a crypto user could be absolutely sure the private key is seen only from him and is generated on his server is to become part of the Ethereum network and create your wallet with “geth” manually by the user himself.
And also be warned DO NOT use insecure sources when:

  1. installing Ubuntu, install it from a cd/dvd/usb downloaded from the official Ubuntu site here.
  2. installing all the needed dependencies from official sources only, not recommended the PPA reposigories, neither!
  3. install yourself the “geth” program, which will create an Ethereum node and after network synchronization could be used to create an Ethereum node.

Three simple rules could almost eliminate leaking your private key to hackers, which in blockchain world means losing your money…
And before start the installation a performance advice do not attempt to run an Ethereum node in a hard disk –

USE SSD

If you use a hard disk even in RAID configuration it could take several days for network synchronization and probably your machine will be useless during the synchronization.

So here are the steps to create from a scratch an Ethereum node:

STEP 1) Install Ubuntu 16 – our howto will be available soon here.

STEP 2) Building from source an Ethereum node

Check out our howto“Building from source an Ethereum node under Ubuntu 16 LTS”.

STEP 3) Start the Ethereum node

if you have followed the howto in STEP 2) you probably have “geth” installed in “~/go-ethereum/build/bin”, so first running it with:

ubuntu@srv.local:~/go-ethereum/build/bin$ ./geth --rpc --fast --cache=8144 &> ./geth.log

STEP 3) Wait for the blockchain network synchronization

When you run “geth” it will check the current state of the network and the current state of your Ethereum node, so no matter it is started for the first time or not a network synchronization is needed, your node need to be synchronized with the Ethereum network to be used for all kind of actions in the network (create a wallet, transfer funds and more).
Here is the output of just started Ethereum node:

As you can see the node connects to another nodes and receives blockchains and saves them to its local database. At present (late February 2017) a fully synchronized Ethereum node takes 59 Gigabytes of space, but this number will changed when you run your node.

STEP 3) Check the progress of the Ethereum network synchronization

The progress of Ethereum node synchronization could be checked with the “geth” program. Execute in the console:

ubuntu@srv.local:~/go-ethereum/build/bin$ ./geth --exec "web3.eth.syncing" attach
{
  currentBlock: 388,
  highestBlock: 5159514,
  knownStates: 0,
  pulledStates: 0,
  startingBlock: 0
}
ubuntu@srv.local:~/go-ethereum/build/bin$ ./geth --exec "web3.eth.syncing" attach
{
  currentBlock: 401,
  highestBlock: 5159514,
  knownStates: 0,
  pulledStates: 0,
  startingBlock: 0
}

As you can see we are at the very beginning here, we’ve received 401 of total 5159514 in the network.

After around 2 hours we are at 4882892 of total 5166333 in the network.

ubuntu@srv.local:~/go-ethereum/build/bin$ ./geth --exec "web3.eth.syncing" attach
{
  currentBlock: 4882892,
  highestBlock: 5166333,
  knownStates: 4806466,
  pulledStates: 4800942,
  startingBlock: 0
}

It is normal the highest block to increment, because the network is used intensively.
STEP 4) Successful full synchronization – how to check and to be sure
When you are almost then like in the last section of the STEP 3) you’ll begin to see lines in the geth output like:

INFO [02-28|01:46:28] Imported new block headers               count=0    elapsed=1.281ms   number=5168639 hash=433308…1a710e ignored=71

and when you execute geth with “web3.eth.syncing”:

ubuntu@srv.local:~/go-ethereum/build/bin$ ./geth --exec "web3.eth.syncing" attach
false

The node will keep on receiving new blocks, so synchronization is triggered again, syncing the received blocks and stops again. So when transferring funds or creating a wallet or any other action there will be triggered a synchronization and then execution of the action. There is a callback for when sync starts and stops. If you cannot see multiple times “false” after the last synchronization check with geth, but your are almost at the highest block, no need to worry everything is OK, you node is almost fully synchronized and can be used.

At present with SSD and 32G RAM on a intel i7 processor and a fast Internet connection 100Mbps the full synchronization took about 8 hours.
