How to Create Your Own Bitcoin Utter Knot With a Raspberry Pi
Why a Bitcoin Total Knot?
Bitcoin is a digital currency supported by a peer-to-peer network. Ter order to run efficiently and effectively, it needs peers run by different people….and the more the better.
This tutorial will describe how to create a Bitcoin “full node” (a Bitcoin server that contains the utter blockchain and propagates transactions across the Bitcoin network via peers). This system will not mine for Bitcoins…it will play its part to keep the Bitcoin peer-to-peer network healthy and strong. For a detailed explanation for why it is significant to have a healthy Bitcoin peer-to-peer network, read this article about Bitcoin total knots.
Also please note this will be a “headless” server…meaning wij will not be using a GUI to configure Bitcoin or check to see how things are running. Ter fact, once the server is set up, you will only interact with it using guideline line calls overheen SSH. The idea is to have this total knot be ordinary, low-power, and something that “just runs” te your basement, plee, etc.
Why a Raspberry Pi?
Raspberry Pi is an inexpensive computing hardware verhoging that generates little warmth, draws little power, and can run silently 24 hours a day without having to think about it.
I determined to create my own Bitcoin total knot on a Raspberry Pi. My Raspberry Pi total knot is up and running, performing well, has about 75 peers and is relaying transactions to the Bitcoin network. I have to say, everzwijn since I got it set up it has bot low maintenance.
I am going to assume that if you are reading this to create your own Raspberry Pi bitcoin total knot, then you already know a little bit about linux, electronics, or running guideline line contraptions like SSH.

Steps to Go after
Prepare the MicroSD Card: The blockchain is growing quickly (30+ GBs at the time of this writing), so I felt 64 GB wasgoed a good size for the Raspberry Pi’s storage. I suppose you could go for 128 GBs to be even more future-proof, if you are willing to spend the money. The MicroSD card will likely come formatted spil exfat, instead of FAT32, but the Raspberry Pi needs FAT32. I recommend using the built-in contraptions on Windows or Mac OSX to format the MicroSD. If you only have a Linux opbergruimte to embark, you most likely already know how to format the microSD card. Since I run a Mac, I just used the built-in Disk Utility and formatted spil “MS-DOS (FAT),” which is indeed FAT32.
Install the operating system: Installing software on a Raspberry Pi can be mildly complicated. I suggest using their NOOBS install manager to make it painless. Just go after the verbinding for NOOBS, download the files and copy them to your FAT32 microSD card and get ready to turning things on.
Initial configuration: There are ways to avoid using a keyboard, movie display, and mouse (KVM) altogether. But ter the rente of keeping things plain I recommend putting your Raspberry Pi into its case, then insert the microSD card into your Raspberry Pi (trust mij, it is lighter to waterput the case on very first), meet up the KVM cables, plugin the ethernet cable, and plugin the power.
At boot up, select Raspbian spil your operating system and let NOOBS get the OS set up. Do not bother with any setting that will launch “startx” (the GUI interface) at boot time, since this utter knot will only be configured via directive line.
