The procedure to execute a complete Bitcoin node, in this case the Bitcoin Core implementation, is very simple. Update your system first.
sudo apt update
sudo apt upgrade
Then install snap: sudo apt install snapd
See if you installed it correctly: snap version
Get pelo bitcoin core: snap find bitcoin core
Install: sudo snap install bitcoin kernel
Now you can run your full node from the terminal by going to the “/snap/bin/bitcoin-core.daemon” directory or running the application graphically.
If you need to show an external directory to store the blockchain, use the following syntax in the terminal “bitcoin-core.daemon -datadir = / mnt / HDD / Bitcoin” (without quotes), where “/ mnt / HDD / Bitcoin “is the path to just” Bitcoin “on your external hard drive.
* Note: ideal is to download the bitcoin code, verify the signatures and compile on your machine. But the above procedure is reliable if you do not keep funds with values that you can not lose.
