As of 2024-03-10 19:30 UTC, Holesky finalized on the correct chain. You can use recent versions of your clients and sync normally.
You need:
- 64 GiB of RAM, or 32 GiB + 32 GiB swap. 16 GiB is unlikely to work

Stabilize an Asus or Intel NUC for 24/7 server operations
Asus (formerly Intel) NUCs weren't designed for use as a 24/7 server, though they see enthusiastic use as such. Some users report instability. And while some of that can be bad RAM or a faulty motherboard / CPU, some can also just be configuration issues. And some is plain heat.
It's a little tough to nail it down. Here are some good practices to follow, to have a stable NUC.
To start, read the official release notes.
If your install fits into "vanilla Ubuntu plus maybe a handful of 3rd-party repos", then this guide for a simple upgrade to Ubuntu 22.04 "Jammy Jellyfish" from Ubuntu 20.04 "Focal Fossa" can be helpful. 3rd-party repos are handled with a find command.
Some Intel NUC10/11 with I225-LM or I225-V Ethernet chip may cause "freezing" of the OS after this update, if wired Ethernet is in use. There are some reports that a BIOS update plus using the hwe kernel can resolve that.
This is a placeholder for instructions when Debian 13 is released in August 2025
To start, read the official release notes.
If your install fits into "vanilla Debian plus maybe a handful of 3rd-party repos", then this guide for a simple upgrade to Debian 13 "trixie" from Debian 12 "bookworm" can be helpful. 3rd-party repos are handled with a find command.
Note upgrade is only supported from Debian 12 to Debian 13. If you are on Debian 11, upgrade to Debian 12 first. Then once on Debian 12, you can upgrade to Debian 13.

Optimal Besu settings for database growth
Besu, an Ethereum execution layer client, is optimized for minimal database growth (7-8 GiB/week) with default parameter --bonsai-limit-trie-logs-enabled. It can use RAM for more block processing speed.
If you have 64 GiB of RAM or more, you can add --Xplugin-rocksdb-high-spec-enabled=true for better performance.
A long-running Besu DB, started before trie-log limit was enabled, will have sizeable trie log storage. This can be reduced
with a one-off prune using the storage trie-log prune subcommand, assuming Besu 24.7.0 or later.
To start, read the official release notes.
If your install fits into "vanilla Ubuntu plus maybe a handful of 3rd-party repos", then this guide for a simple upgrade to Ubuntu 24.04 "Noble Numbat" from Ubuntu 22.04 "Jammy Jellyfish" can be helpful. 3rd-party repos are handled with a find command.
Note upgrade is only supported from Ubuntu 22.04 or later to Ubuntu 24.04. If you are on Ubuntu 20.04, upgrade to Ubuntu 22.04 first. Then once on Ubuntu 22.04, you can upgrade to Ubuntu 24.04.
To start, read the official release notes.
If your install fits into "vanilla Debian plus maybe a handful of 3rd-party repos", then this guide for a simple upgrade to Debian 12 "bookworm" from Debian 11 "bullseye" can be helpful. 3rd-party repos are handled with a find command.
Note upgrade is only supported from Debian 11 to Debian 12. If you are on Debian 10, upgrade to Debian 11 first and make sure to change the security repo as per the release notes. Then once on Debian 11, you can upgrade to Debian 12.
- Check free disk space
Nethermind as of January 2024 takes about 1.1 TiB of space on a snap sync, and then grows by ~ 27 GiB/week.
When it starts to fill its disk, it can be online pruned (no downtime) to free up space again, to around the size of a fresh sync.
- This is not an archive node. Do not try to prune an archive node.
A typical user of eth-docker is someone who wants to become a validator on the Ethereum network, also known as staking or staker, or someone who is already a validator on the Ethereum network and wants to add more validators to their setup. They can be someone who is going to setup their machine at home, someone who is going to use some kind of VPS to host their setup, or some kind of institutional staker working for large staking services or large investors.
eth-docker is an automation wrapper to run an "Ethereum node", consisting of a consensus layer client, execution layer client, and validator client.
Geth 1.10.23 fixes a bug in 1.10.22, which would have resulted in missing state in its database. The Go-Ethereum team recommends to roll the chain back and let Geth catch up again, if and only if you had updated to 1.10.22. If you did not, just update to 1.10.23 now and call it done.
This is how to roll back to a previous block when using eth-docker.
./ethd update and ./ethd up should do it.
