Erigon

Erigon is a client implementation focused on performance and saving disk space, written in Go.

important Install and run an Erigon if you want to follow the Linea

network by maintaining a local copy of the blockchain. However, if you want to interact with the network and use Linea-specific methods and features, you should install Linea Besu instead. :::

You can run Erigon from a binary distribution or using Docker.

Run using the binary distribution​

info

Ensure you review Erigon's software prerequisites before installing the Erigon client.

If you're not comfortable with installing the binary distribution, consider using Docker instead.

Step 1. Install Erigon​

Download and install the Erigon client.

Step 2. Download the genesis file​

Download the genesis file for the relevant network. In the example, we'll download the file to the directory specified by datadir in Step 4.

Mainnet genesis.json file.

Step 3. Define disk space volume (optional)​

Define a volume size appropriate to your expected usage. As of October 8 2024, Erigon nodes use:

  • Full nodes: 122GB.
  • Archive nodes: 472GB.

Use these figures as a basis to determine the extent to which you want to future-proof your node.

Ensure you mount the Erigon datadir to the custom volume.

If you run out of space, or need to actively maintain how much space is being used, consider pruning.

note

Blockchain clients 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.
  • 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.
  • 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.
  • 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.
  • 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. Bootstrap your node​

Bootstrap the node using the following command:

erigon --datadir $HOME/erigon-mainnet-data/ init
$HOME/erigon-mainnet-data/genesis.json

Step 5. Start the Erigon client​

Start the node using the following command:

erigon \
--datadir $HOME/erigon-mainnet-data/ \
--networkid 59144 \
--rpc.allow-unprotected-txs \
--txpool.accountqueue 50000 \
--txpool.globalqueue 50000 \
--txpool.globalslots 50000 \
--txpool.pricelimit 1000000 \

--txpool.nolocals \

:::note[bootnodes] You can choose from a range of bootnodes for Linea Mainnet. The above command uses all bootnodes by default.

The bootnodes page contains a full list of available bootnodes. :::

The Erigon node will attempt to find peers to begin synchronizing and to download the world state.

Run using Docker​

Prerequisites​

Download and install Docker.

Step 1. Download configuration files​

Download the configuration files for the relevant network. Ensure that you download the files to the same directory.

Download the mainnet docker-compose.yml and genesis.json files.

:::note[bootnodes] You can choose from a range of bootnodes for Linea Mainnet. The above command uses all bootnodes by default.

Step 2. Start the Erigon node​

Open up a terminal where the both docker-compose.yml and genesis.json are located (they should be in the same directory) and run docker compose up

The node should now be running and looking for peers to sync.

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"
  }
}
