Bitcoin - The Currency of the Internet

A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.

How to use Bitcoin Core only?

I'm wondering how one would restore a wallet that was made from a BIP39 seed to a Bitcoin Core wallet? Bitcoin Core does not use BIP39. So I presume you'd have to provide it the master private key.. but what is that exactly? Because on Ian Coleman's BIP39 utility website.... it shows BIP32 Root Key, Account Extended Private Key, and BIP32 Extended Private key... they are all different... which one would work to use in Bitcoin Core?
How would one backup their Bitcoin Core wallet private key? Is there an applicable mnemonic? Or is it just the private key?
Does Core work with QR codes? (Reading and Generating?)

How to use Bitcoin Core with ColdCard?

I setup with Electrum and read how to sign (approve) transactions without plugging in my hardware wallet to the computer directly.
But I also saw the option to export my wallet's setup to Bitcoin Core. I'd rather use a full node than depend/trust someone else as is the case with Electrum.
I don't see on YouTube or elsewhere how to go back and forth between my hardware wallet's SD card and Bitcoin Core on my laptop to sign transactions. Can anyone point me to rhe self-help how-to resources for this, please?

I Did It! I figured out how to use Bitcoin. I am downloading Bitcoin Core Wal. but have not used it yet. I have never used bitcoin. While it installs, I installed Electrum on my Mac & bought $4 of bit on CashApp & moved to My Wallet on Electrum. I lost like 11cents on $4.13. It there a cheaper way?

How to run Bitcoin Core 0.20.0 on Ubuntu Server 20.04 LTS using a Raspberry Pi 4 (or Virtual Machine)

I was helping someone on twitter with this so I figured I'd share the information here as well so that other people would have an easier time than I did.
I'm going to explain how to do this setup on a Raspberry Pi, but note that this should work on a VM as well. You can also set up and run the node headless this way, but I will be explaining how to set up the node using a monitor that you can then later disconnect and access remotely once everything is setup.
Hardware:
-Raspberry Pi 4 (2GB RAM minimum) preferably 4GB RAM -Raspberry Pi 4 Heatsinks -Raspberry Pi 4 case -Micro HDMI cable -USB-C power cable and wall adapter -Monitor -Keyboard and mouse -Ethernet cable (Optional) -16GB or larger microSD card -500GB or larger external hard drive (SSD or portable)
Node Requirements: -50 KBps upload internet speeds (Most people should have this) -Unlimited or high data cap internet download/upload service -6 hours or longer per day dedicated run time
Okay, once you have the hardware its time to get started!
The first thing you'll need to do is install the Raspberry Pi imager, this is how we're going to install Ubuntu onto our Raspberry Pi. After your download and install finishes, open the imager.
  1. Click the "choose OS" box and from the list select Ubuntu, then select Ubuntu Server 20.04 LTS (Raspberry Pi 2/3/4).
  2. Insert your microSD card to your computer directly or via a USB converter. Click "choose SD card" and select your inserted microSD card.
  3. Click "Write" and wait for the imager to finish flashing the OS onto your card
When it is done, remove the SD card and reinsert it to access the files installed. You can choose the overclock the Raspberry Pi by editing the config file. To connect to the Raspberry Pi remotely, you'll need to create an SSH file. If you're on windows this is pretty easy. In the File Explorer, highlight the address bar at the top, erase the text and type cmd, press enter and the Command Prompt will pop up. Type the following:
echo\ssh
This will create an SSH file in your SD directory so that you can remote access the Rasberry Pi later. Now you can go ahead and eject the SD card from your computer.
Now we can set up the Raspberry Pi
Go ahead and connect all your peripherals to your Raspberry Pi, insert the microSD, and connect it to power to turn it on. Give it a moment to boot up, then when prompted enter "ubuntu" for the password. It will make you change the password. Afterward, it will print a bunch of information to the screen, write down the IPv4 address, this is the IP address you'll use to remote access the Raspberry Pi. Now, at any time you can remote access your Raspberry Pi by entering a terminal on another PC in your network and typing:
ssh [email protected](your IP address)
The next step is to install a desktop. There are plenty to choose from so feel free to use a different one than what I use, you can also choose to ignore this and to just work from in the terminal from this point forward.
You need to update all the repositories so type: (Note you'll either have to be connected by ethernet or have edited the network-config file to setup your wifi in advance)
sudo apt-get update
Once it's done updating type the following to upgrade your system:
sudo apt-get upgrade
Now that you're up-to-date, you can install the desktop using the command:
sudo apt-get install ubuntu-gnome-desktop
This will take a while to download and install so just sit back and let it do its thing. Once it's done downloading, restart your Raspberry Pi and log in with the password you changed earlier. Your first boot may take a while so just be patient, don't freak out if you see a single purple square in the center of the screen while it's loading. You should now have the Ubuntu desktop ready to go and now it's on to installing Bitcoin Core!
Installing Bitcoin Core 0.20.0
Since we're running Ubuntu Server 20.04 LTS, it should come preinstalled with the Snap Store. This makes installing apps very easy and works similar to pip install in Python. Simply open your terminal and type:
sudo snap install bitcoin-core
This will install Bitcoin Core into your Snap folder and will add the application to your system. Unfortunately, there are still a few steps left before we can begin downloading the blockchain. By default, Bitcoin Core doesn't have the removable-media Plug connected to the Socket. You can view this by typing:
snap connections bitcoin-core
This means when you try installing everything onto your external hard drive, Bitcoin Core won't be able to identify it or write to it even when passed the directory path. To fix this first locate your Snap folder, make a copy of the bitcoin-core folder inside, and paste it into your external drive.
NOTE: You must make a copy, you can't just move the snap file to the external drive.
Now, you can connect the removable-media Plug to the Socket by typing:
sudo snap connect bitcoin-core:removable-media :removable-media
This gives you the read/write permissions necessary to access the /media path. Finally, you can now launch Bitcoin Core and select "use a custom directory path" when prompted. Highlight the current directory path and replace it with the path to your external hard drive, it should look something like this:
/media/(external drive)/bitcoin-core/common/.bitcoin
This is why we had to make a copy of the bitcoin-core folder to the external drive earlier, the Bitcoin Core application will create the new data directory through ".bitcoin". Hit "Okay" and the application will begin synchronizing with the network! Once the synchronization is finished your very own node will be up and running!
EDIT: (08/01/2020) Bitcoin Core 0.20.01 has been released, I will update the tutorial soon with how to run the latest release.

Brian Hoffman: "People suggesting that Facebook use Bitcoin [Core] instead of Libra is kind of confusing to me. I mean even if Lightning scales to their level, how could they support peer to peer payments without addressing the invoice-less payments issue? This seems prohibitive (not insurmountable)

Olivier Janssens: "To the Bitcoin Core people: Transaction fees are rising fast. How will people with less money (or doing small transactions) be able to use their own private wallets instead of being forced on exchanges and centralized solutions? (Not Lightning. Same fees to open channels & alpha)"

How do I use my bitcoin core node to validate transactions against BRD, HODL, Samourai or other mobile wallets???

I have my bitcoin core node setup. I use electrum personal server and can connect electrum to my own core node just fine. However, all of these mobile wallets that allow you to "switch to manual mode" and use your own bitcoin core node dont seem to work. Some allow you to put in your RPC Username/Password and others just allow you to put in an IP and a Port. I am obviously connecting via my own local LAN between my phone and the core node. I have server=1 set in my config and I have an RPC usepassword/port setup as well. What else needs to be done here or does anyone have any tips/tricks to get this to work? Thanks.

The wallet is installed on computers running operating systems: I have set up a full node with bitcoin core running on the internet. I have also set up a wallet running on a private machine that communicates to the full node to broadcast new transactions. To enhance privacy, I plan to enable Tor on the full node. However, it is not clear to me how to use Tor only for broadcasting new transactions from my ... Bitcoin Core is programmed to decide which block chain contains valid transactions. The users of Bitcoin Core only accept transactions for that block chain, making it the Bitcoin block chain that everyone else wants to use.
