Ethereum on ARM. Turn your ARM device into a full Ethereum node just by flashing a MicroSD card

Ethereum on ARM is a project that provides custom Linux images for ARM devices that run Geth, Parity and Nethermind Ethereum clients as a boot service and automatically turns these ARM boards into a full Ethereum node.

Why running a full node?

You may ask yourself, why should I run a full Ethereum node? Well, probably, there is not a perfect answer to this question but this quote from Mastering Ethereum book is a good one: “The health, resilience, and censorship resistance of blockchains depend on them having many independently operated and geographically dispersed full nodes. Each full node can help other new nodes obtain the block data to bootstrap their operation, as well as offering the operator an authoritative and independent verification of all transactions and contracts.”

So, basically, what you are doing by running a full node is supporting the Ethereum network. Other possible reasons to run a node are: validate / send transactions without relying on third party services, host your own node infrastructure to develop Dapps or test eth2.0 implementations.

Why ARM devices?

Think about it, if you are going to run a full node, would you be willing to let your laptop or desktop running 24/7 for such a specific task? Would you buy an expensive server?. We did ask ourselves these questions when we first decided to run full nodes some years ago and came to the conclusion that ARM devices are the most convenient devices for doing so.

Among other reasons:

What is Ethereum on ARM

Ethereum on ARM provides images to easily turn you ARM device into a full Ethereum node. Images take care of all necessary steps, from setting up the environment and formatting the SSD disk to installing and running the Ethereum software as well as synchronizing the blockchain.

Installation steps

Download the latest Ethereum on ARM image

Unzip the downloaded file

[fernando@etherNode ~]$ unzip
  inflating: 2019-12-20-EthRaspbian2.0-lite.img

Flash the uncompressed image

We need to find the right block device in order to flash the image

[fernando@etherNode ~]$ lsblk -P -M  -o PATH,MODEL
PATH="/dev/sda" MODEL="ST1000LM049-2GH172"
PATH="/dev/sda1" MODEL=""
PATH="/dev/sda2" MODEL=""
PATH="/dev/sdc" MODEL="Micro_SD_M2"
PATH="/dev/sdc1" MODEL=""
PATH="/dev/nvme0n1" MODEL="CT500P1SSD8"
PATH="/dev/nvme0n1p1" MODEL=""
PATH="/dev/nvme0n1p2" MODEL=""
PATH="/dev/nvme0n1p3" MODEL=""
PATH="/dev/nvme0n1p4" MODEL=""
PATH="/dev/nvme0n1p5" MODEL=""
PATH="/dev/nvme0n1p6" MODEL=""

In this case /dev/sdc is the MicroSD card. Other possible device is /dev/mmcblk0

Flash the image to the right device

[fernando@etherNode ~]$ sudo dd bs=1M if=2019-12-20-EthRaspbian2.0-lite.img of=/dev/sdc conv=fdatasync status=progress
2480930816 bytes (2,5 GB, 2,3 GiB) copied, 2 s, 1,2 GB/s

And that's it. Easy! isn't it?

Note: **If you have a Windows desktop you can use Balena Etcher to flash the MicroSD

Addendum. Some pictures of the installation

Power consumption during sync

It is very important to connect the SSD to the blue USB port

Try to get a case with a cooler kit
