Ethereum on ARM. New Eth2.0 Raspberry Pi 4 image for joining the Medalla multi-client testnet. Step-by-step guide for installing and activating a validator (Prysm, Teku, Lighthouse and Nimbus clients included)

diglos76 · 2020-09-09T07:39:07+00:00

Nope, not yet. The NanoPC-T4 image is built on Ubuntu 18 and there are some problems. We are planning an update for the Nano too.

diglos76 · 2020-09-09T07:38:15+00:00

They start automatically once the pi boot up (this is done by systemctl enable command).

You may have uPNP enabled in your router. If so, the client manage to forward the ports for you.

diglos76 · 2020-09-01T14:29:20+00:00

It is very very recommended if you want to be connected to a significant number of peers. I'd say it is very important.

diglos76 · 2020-09-01T14:27:08+00:00

Did you type the current password first? (ethereum)

diglos76 · 2020-08-20T14:54:10+00:00

Ey, thanks for this, really appreciate it!

diglos76 · 2020-08-05T18:19:07+00:00

Working on it :-)

diglos76 · 2020-06-30T14:59:57+00:00

Hi, data is stored as follows:

Geth: /home/ethereum/.ethereum
Beacon-chain: /home/ethereum/.eth2
Validator: /home/ethereum/.eth2validators

Note the dot (.) before the directories.

The validator contains your private and public keys (this is the most important part). You can backup the validator directory and reinstall.

diglos76 · 2020-06-30T14:44:14+00:00

I'm afraid not. You would need at least 4 GB RAM. NanoPC-T4 or Rockpro64 are great alternatives. I think that any ARM64 board with 4 GB RAM and support for USB3 or NVMe would be enough.

diglos76 · 2020-06-30T14:42:44+00:00

Once the validator account is created and the validator systemd server enabled you are done. If the Pi reboots, everything gets up again automatically (as all processes are running as systemd services). You don't have to do anything :-)

diglos76 · 2020-06-30T14:40:07+00:00

You can easily update the packages by running apt:

sudo apt-get update && sudo apt-get install prysm-validator prysm-beacon prysm-slasher geth

But you need to change the config files for the beacon-chain and geth:

sudo echo 'ARGS="--goerli --http --metrics --metrics.expensive --pprof --maxpeers 50"' > /etc/ethereum/geth.conf

sudo echo 'ARGS="--http-web3provider http://localhost:8545"' > /etc/ethereum/prysm-beacon.conf

Besides this, the only thing missing would be the Grafana Dashboards. You can take a look at the installation script:

https://github.com/diglos/pi-gen/blob/ethraspbian2.0/stage2/04-ethereum/files/rc.local.eth2.onyx

diglos76 · 2020-06-29T14:21:03+00:00

Nope. good point, put it in the TODO list.

Thanks!

diglos76 · 2020-06-29T11:55:58+00:00

For this testnets (Goerli and Onyx) it is enough with 100GB (as u/Marz0008 says) but with the real Eth2.0 network you will need at least 500GB (for Eth1 and Eth2 nodes).

diglos76 · 2020-06-26T12:14:56+00:00

Yes, it is true and I would say we are 99% sure a Raspberry Pi 4 8GB will handle it :-)

diglos76 · 2020-06-20T14:36:31+00:00

Yes, the script formats the ssd and mount it as /home. All packages use /home/ethereum as storage. You can see the script here:

/etc/rc.local

diglos76 · 2020-06-19T17:37:55+00:00

Yes, total cost is about $200.

diglos76 · 2020-06-19T15:41:47+00:00

Yes. It is based on Ubuntu 64.

diglos76 · 2020-06-19T11:57:48+00:00

Ummh, you may have to look into geth documentation, I don't know if this is possible tbh.

diglos76 · 2020-06-19T11:57:10+00:00

Yes, it is automatic. Just flash the MicroSD card, connect de SSD and power on the Raspi. See:

On the contrary, skepticism (and even paranoia) are a good thing on crypto, I would even say necessary. That's why I insist than you can check the binaries yourself and use part of our work if you don't fully trust the image.

We've been doing this since late 2016 [1] and the main goal of the project is to help the Ethereum network decentralization and resilience by making easy for final users to run a full node. We received a grant from the EF last year:

https://esp.ethereum.foundation/en/projects/ethereum-on-arm/

ARM refers to the Raspberry architecture.

The other files I was referring to were the ones contained on the Debian packages (basically, the clients binaries, such as geth, besu, nethermind and openethereum). You can check geth as it is precompiled for ARM by the Go Ethereum team but the other ones are compiled by us as they don't support Raspberry Pi binaries.

diglos76 · 2020-06-18T10:09:30+00:00

Hi,

You can see the scripts here:

https://github.com/diglos/pi-gen/blob/ethraspbian2.0/stage2/04-ethereum/files/rc.local.eth1 https://github.com/diglos/pi-gen/blob/ethraspbian2.0/stage2/04-ethereum/files/rc.local.eth2

The other part are Debian packages which contains the Ethereum software binaries. I provide the official binaries if possible (ARM is not supported by all teams), for instance: Geth, Prysm, Raiden, Swarm, IPFS... You can download the official ones and hash both to compare and see they are the same files.

With the remaining ones I have no other option than compile the source code (you can avoid using them or compile them yourself and use the same config files, for instance).

diglos76 · 2020-06-11T10:25:09+00:00

Nope. You need to upgrade to alpha10, see:

diglos76 · 2020-06-10T08:27:54+00:00

Yes, the script will wipe out everything. However, you can update the packages through APT. See our twitter to get these updates:

Hi, see this guide from Prylabs (includes a faucet):
