Use a binary distribution
You can install the Besu or Geth client to run a Linea node from a binary distribution. For Besu nodes, you have a choice between:
- Using standard Besu software to run a follower node, which keeps a local copy of the blockchain, or;
- Using Linea Besu if you intend to use the node to interact with the blockchain, or provide it to others to do so. Linea Besu extends Besu's functionality with plugins and is recommended for infrastructure providers.
Prerequisites​
Set up the required and recommended hardware and all the utilities. You can find the recommendations for the clients from the official documentation:
- Besu
- Geth.
- Linea Besu: Download the latest version of
linea-besu-package
from its releases page. Find the "Assets" subheading on the latest release and download the zip file namedlinea-besu-package-<version>.tar.gz
.
Run a standard Besu client​
Step 1. Install Besu​
Download and install Besu using the instructions in the official documentation.
Step 2. Download the genesis file and Besu configuration file​
Download the genesis file and Besu configuration file.
- Mainnet
- Linea Sepolia
Mainnet genesis-mainnet.json
file and Besu
config-mainnet.toml
file.
You can choose from a range of edge nodes (enodes) for Linea Mainnet. The Besu config-mainnet.toml
file uses all enodes by default.
See our enodes page for a full list of available enodes.
Testnet genesis-sepolia.json
file and Besu
config-sepolia.toml
file.
Step 3. Define disk space volume (optional)​
Define a volume size appropriate to your expected usage. As of March 20 2024, Besu nodes use:
- Full nodes: 120GB, growing ~1.5GB per day.
- Archive nodes: 740GB, growing ~9.5GB per day.
Use these figures as a basis to determine the extent to which you want to future-proof your node.
To limit disk space required, we recommend you configure Besu to use the Bonsai data storage format, which prunes orphaned nodes and old branches.
Ensure you mount the Besu data-path
to the custom volume when you start the node.
Blockchain clients like Besu or Geth can take up a lot of disk space. By defining the amount of disk space you're willing to dedicate to your client (and the block data that it will be syncing), you can ensure that you still have enough room on your disk for whatever else you need.
Select the relevant operating system for the steps on how to create a custom volume.
Ubuntu
- Open Terminal
- Use the
df -h
command to check the available disk space - Choose a maximum size for the volume. We'll use 100GB for this example, but refer to the Geth or Besu explanation to help determine the value.
- Use
fallocate
to create a file of the desired size, e.g.fallocate -l 100G myfile.img
- Use
mkfs.ext4
to format the file as an ext4 filesystem. e.g.mkfs.ext4 myfile.img
- Mount the file using
mount
, e.g.mount -o loop myfile.img /mnt/myvolume
- The contents will now be available in
/mnt/myvolume
, up to a maximum of 100GB
MacOS
- Open Terminal
- Use the
df -h
command to check the available disk space - Choose a maximum size for the volume. We'll use 100GB for this example, but refer to the Geth or Besu explanation to help determine the value.
- Use
hdiutil
to create a sparse image of the desired size, e.g.hdiutil create -size 100g -type SPARSE -fs HFS+X myfile.dmg
- Mount the image using
hdiutil
, e.g.hdiutil attach myfile.dmg
- The contents will now be available mounted under
/Volumes
, up to a maximum of 100GB
Windows
Without Windows Subsystem Linux
- Open Command Prompt as Administrator
- Use the
dir
command to check available disk space on the volume you want to create the disk image - Choose a maximum size for the volume. We'll use 100GB for this example, but refer to the Geth or Besu explanation to help determine the value.
- Use the
fsutil
command to create a sparse file of the desired size, e.g.fsutil file createnew myfile.img 107374182400
(for a 100GB file) - Initialize the disk image using
diskpart
:diskpart
select vdisk file="myfile.img"
create vdisk maximum=100000
attach vdisk
exit
- Format the volume using
format
, e.g.format F: /FS:NTFS /A:64K /Q
- The new volume will now be available as drive letter F:, up to the maximum 100GB size
To mount an existing disk image:
- Open Command Prompt as Administrator
- Use
diskpart
select vdisk file="myfile.img"
attach vdisk
- The disk image will be mounted and accessible under the assigned drive letter
With Windows Subsystem Linux
- Open WSL
- Use the
df -h
command to check the available disk space - Choose a maximum size for the volume. We'll use 100GB for this example, but refer to the Geth or Besu explanation to help determine the value.
- Use
fallocate
to create a file of the desired size, e.g.fallocate -l 100G myfile.img
- Use
mkfs.ext4
to format the file as an ext4 filesystem. e.g.mkfs.ext4 myfile.img
- Mount the file using
mount
, e.g.mount -o loop myfile.img /mnt/myvolume
- The contents will now be available in
/mnt/myvolume
, up to a maximum of 100GB
Step 4. Configure the Besu configuration file.​
In your Besu configuration file (config-mainnet.toml
, config-goerli.toml
, or config-sepolia.toml
), configure
the following options:
- Set
data-path
to the location you want to store your data. - Set
genesis-file
to the path of your downloaded genesis file.
Step 5. Start the Besu client​
Run the Besu client with the location of your configuration file. For example:
- Mainnet
- Linea Sepolia
besu --config-file=/Users/myuser/mainnet/config-mainnet.toml
besu --config-file=/Users/myuser/sepolia/config-sepolia.toml
The Besu node will attempt to find peers to begin synchronizing and to download the world state.
Run a Linea Besu node​
Please note that the advanced
profile option does not currently support macOS/ARM. Please use
Linux/ARM or Windows/X86_64.
Linea Besu is an implementation of the Besu client that extends its functionality.
We recommend using Linea Besu over standard Besu if you intend to run a node and use it to interact with the blockchain, rather than just following it.
Linea Besu enables you to use plugins adapted specifically for Linea, such as the Linea Sequencer plugin.
These plugins are necessary, in different ways, to enable full functionality for the node.
Linea-specific API endpoints like linea_estimateGas
, for example, require the linea-sequencer
plugin. You can pick a plugin by selecting a profile in step 2.
This guide is for infrastructure providers and operators who intend to run a Linea node. This is relevant to you if:
- You are responsible for operating nodes as a service for others to use
- You want to use Linea with a personal, private RPC endpoint.
Step 1. Unzip the folder​
The linea-besu-package-<version>.tar.gz
is a zip file; move it to the directory of your choice
and unzip it.
Step 2. Select a profile​
In the unzipped directory, find profiles
. The .toml
configuration files in this folder define
the parameters for each possible profile you can select for your Linea Besu node.
- Mainnet
- Linea Sepolia
Select one according to your preferences:
basic-mainnet
: Creates a basic follower node on Linea Mainnet with no plugins enabled.advanced-mainnet
: Creates an advanced node on Linea Mainnet with plugins that enable support forlinea_estimateGas
and thefinalized
block parameter tag.
Select one according to your preferences:
basic-testnet
: Creates a basic follower node on Linea Sepolia with no plugins enabled.advanced-testnet
: Creates an advanced node on Linea Sepolia with plugins that enable support forlinea_estimateGas
and thefinalized
block parameter tag.
Step 3. Start the Linea Besu client​
In a terminal, navigate to the linea-besu-package-<version>
directory, where the bin
, genesis
,
profiles
etc. directories are.
Now run Linea Besu, specifying your preferred profile. The --plugin-linea-l1-rpc-endpoint
must
only be defined if you are running an advanced
node, since this is needed to query finalization
on L1.
- Mainnet
- Linea Sepolia
bin/besu --profile=advanced-mainnet --plugin-linea-l1-rpc-endpoint=<endpoint>
bin/besu --profile=advanced-testnet --plugin-linea-l1-rpc-endpoint=<endpoint>
The node will attempt to find peers to begin synchronizing and to download the world state.
Run the Geth client​
Step 1. Install Geth​
Download Geth and install using the instructions provided here.
Linea only supports Geth up to v1.13.15 or lower. v1.14.0 and subsequent versions are not supported.
Step 2. Download the genesis file​
Download the genesis file for the relevant network.
- Mainnet
- Linea Sepolia
Mainnet genesis.json
file.
Sepolia genesis.json
file.
Step 3. Define disk space volume (optional)​
Define a volume size appropriate to your expected usage. As of March 20 2024, Geth nodes use:
- Full nodes: 170GB, growing ~2.6GB per day.
- Archive nodes: 760GB, growing ~10GB per day.
Use these figures as a basis to determine the extent to which you want to future-proof your node.
Ensure you mount the Geth datadir
to the custom volume.
If you run out of space, or need to actively maintain how much space is being used, consider pruning.
Blockchain clients like Besu or Geth can take up a lot of disk space. By defining the amount of disk space you're willing to dedicate to your client (and the block data that it will be syncing), you can ensure that you still have enough room on your disk for whatever else you need.

The Linea network only produces blocks if there is currently at least 1 pending transaction. If you see no incoming blocks to your node, that does not mean that the node is not syncing.
If you don't see any incoming blocks, check and make sure that you have at least one peer from the bootnodes; otherwise, you might not be connected to the Linea network.
Confirm the node is running​
You can call the JSON-RPC API methods to confirm the node is running. For example, call
eth_syncing
to return the synchronization status.
For example the starting, current, and highest block, or false
if not synchronizing (or if the head of the chain has been reached).
curl localhost:8545 \
-X POST \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}'
You should get a result similar to:
{
"jsonrpc": "2.0",
"id": 1,
"result": {
"startingBlock": "0x0",
"currentBlock": "0x5d228",
"highestBlock": "0x3cedec"
}
}
