How to operate a Bitcoin Cash Full Node (Bitcoin Unlimited) on Raspberry Pi
A few weeks ago, Jamie Redman wrote an article about Bitcoin Cash full node. He mentioned there that a Bitcoin Cash full node can be executed on Raspberry Pi. Since I have such a full node and people asked me, I decided to write how I do it.
To execute a Bitcoin Cash full node on Raspberry Pi, I use:
Raspberry Pi 3 (32 Bit, 1 GB RAM, 16 GB SD-Card)
1 TB USB HDD
Bitcoin Unlimited full node software
Internet connection ↓ 90,0 Mbit/s ↑ 32,0 Mbit/s
I bought Raspberry Pi with the operating system pre-installed, so I didn't have to install it. If you want to install it yourself, you can read how to do it here .
I use a LAN cable to connect to my router. However, you can also make a Wi-Fi connection.
How to install Bitcoin Unlimited on Raspberry Pi you can read here . Which files arm32 or arm64 you need to download depends on which operating system you are using. I use the 32bit operating system.
I installed the node using the following commands:
I don't connect my Raspberry Pi to the monitor and keyboard, but do everything remote.
Downloading the complete blockchain on Raspberry Pi takes a long time, so I connected my USB hard drive to my PC and downloaded it there. Therefore I installed the Windows version of Bitcoin Unlimited on my PC. I have created a folder "Bitcoin" on the USB hard disk for the blockchain, but you can name the folder as you like. Then I started bitcoin-qt and specified the directory "Bitcoin" as target for the data.
Downloading the blockchain took me about 22 hours (I did it a few days ago).
After downloading the Blockchain to the PC, I closed bitcoin-qt and connected the hard disk to the Raspberry Pi via a USB cable. It was mounted there automatically and can be accessed as /media/pi/Volume. Now I had to tell my BU node on the Raspberry Pi where the blockchain is located. To do this I opened the file bitcoin.conf using nano (if the file does not yet exist, it must be created):
