Disclaimer: this software is currently a tech preview. We will do our best to keep it stable and make no breaking changes but we don't guarantee anything. Things can and will break.

Important defaults: Erigon is an Archive Node by default (to remove history see: --prune flags in erigon --help). We don't allow change this flag after first start.

System Requirements

• For an Archive node of Ethereum Mainnet we recommend >=3.5TB storage space: 2.2TB state (as of December 2023), 470GB snapshots (can symlink or mount folder <datadir>/snapshots to another disk), 200GB temp files (can symlink or mount folder <datadir>/temp to another disk). Ethereum Mainnet Full node ( see --prune* flags): 400Gb (April 2022).

• Goerli Full node (see --prune* flags): 189GB on Beta, 114GB on Alpha (April 2022).

• Gnosis Chain Archive: 600GB (October 2023).

• Polygon Mainnet Archive: 8.5TiB (December 2023). --prune.*.older 15768000: 5.1Tb (September 2023). Polygon Mumbai Archive: 1TB. (April 2022).

SSD or NVMe. Do not recommend HDD - on HDD Erigon will always stay N blocks behind chain tip, but not fall behind. Bear in mind that SSD performance deteriorates when close to capacity.

RAM: >=16GB, 64-bit architecture.

Golang version >= 1.20; GCC 10+ or Clang; On Linux: kernel > v4

Usage

Getting Started

For building the latest release (this will be suitable for most users just wanting to run a node):

git clone --branch release/<x.xx> --single-branch https://github.com/ledgerwatch/erigon.git
cd erigon
make erigon
./build/bin/erigon

You can check the list of releases for release notes.

For building the bleeding edge development branch:

git clone --recurse-submodules https://github.com/ledgerwatch/erigon.git
cd erigon
git checkout devel
make erigon
./build/bin/erigon

Default --snapshots for mainnet, goerli, gnosis, chiado. Other networks now have default --snapshots=false. Increase download speed by flag --torrent.download.rate=20mb. 🔬 See Downloader docs

Use --datadir to choose where to store data.

Use --chain=gnosis for Gnosis Chain, --chain=bor-mainnet for Polygon Mainnet, --chain=mumbai for Polygon Mumbai and --chain=amoy for Polygon Amoy. For Gnosis Chain you need a Consensus Layer client alongside Erigon (https://docs.gnosischain.com/node/manual/beacon).

Running make help will list and describe the convenience commands available in the Makefile.

Datadir structure

• chaindata: recent blocks, state, recent state history. low-latency disk recommended.
• snapshots: old blocks, old state history. can symlink/mount it to cheaper disk. mostly immutable. must have ~100gb free space (for merge recent files to bigger one).
• temp: can grow to ~100gb, but usually empty. can symlink/mount it to cheaper disk.
• txpool: pending transactions. safe to remove.
• nodes: p2p peers. safe to remove.

Logging

Flags:

• verbosity
• log.console.verbosity (overriding alias for verbosity)
• log.json
• log.console.json (alias for log.json)
• log.dir.path
• log.dir.prefix
• log.dir.verbosity
• log.dir.json

In order to log only to the stdout/stderr the --verbosity (or log.console.verbosity) flag can be used to supply an int value specifying the highest output log level:

  LvlCrit = 0
  LvlError = 1
  LvlWarn = 2
  LvlInfo = 3
  LvlDebug = 4
  LvlTrace = 5

To set an output dir for logs to be collected on disk, please set --log.dir.path If you want to change the filename produced from erigon you should also set the --log.dir.prefix flag to an alternate name. The flag --log.dir.verbosity is also available to control the verbosity of this logging, with the same int value as above, or the string value e.g. ' debug' or 'info'. Default verbosity is 'debug' (4), for disk logging.

Log format can be set to json by the use of the boolean flags log.json or log.console.json, or for the disk output --log.dir.json.

Modularity

Erigon by default is "all in one binary" solution, but it's possible start TxPool as separated processes. Same true about: JSON RPC layer (RPCDaemon), p2p layer (Sentry), history download layer (Downloader), consensus. Don't start services as separated processes unless you have clear reason for it: resource limiting, scale, replace by your own implementation, security. How to start Erigon's services as separated processes, see in docker-compose.yml.

Embedded Consensus Layer

On Ethereum Mainnet, Görli, and Sepolia, the Engine API can be disabled in favour of the Erigon native Embedded Consensus Layer. If you want to use the internal Consensus Layer, run Erigon with flag --internalcl. Warning: Staking (block production) is not possible with the embedded CL.

Testnets

If you would like to give Erigon a try, but do not have spare 2TB on your drive, a good option is to start syncing one of the public testnets, Görli. It syncs much quicker, and does not take so much disk space:

git clone --recurse-submodules -j8 https://github.com/ledgerwatch/erigon.git
cd erigon
make erigon
./build/bin/erigon --datadir=<your_datadir> --chain=goerli

Please note the --datadir option that allows you to store Erigon files in a non-default location, in this example, in goerli subdirectory of the current directory. Name of the directory --datadir does not have to match the name of the chain in --chain.

Block Production (PoW Miner or PoS Validator)

Disclaimer: Not supported/tested for Gnosis Chain and Polygon Network (In Progress)

Support only remote-miners.

• To enable, add --mine --miner.etherbase=... or --mine --miner.miner.sigkey=... flags.
• Other supported options: --miner.extradata, --miner.notify, --miner.gaslimit, --miner.gasprice , --miner.gastarget
• JSON-RPC supports methods: eth_coinbase , eth_hashrate, eth_mining, eth_getWork, eth_submitWork, eth_submitHashrate
• JSON-RPC supports websocket methods: newPendingTransaction

🔬 Detailed explanation is here.

Windows

Windows users may run erigon in 3 possible ways:

• Build executable binaries natively for Windows using provided wmake.ps1 PowerShell script. Usage syntax is the same as make command so you have to run .\wmake.ps1 [-target] <targetname>. Example: .\wmake.ps1 erigon builds erigon executable. All binaries are placed in .\build\bin\ subfolder. There are some requirements for a successful native build on windows :

  • Git for Windows must be installed. If you're cloning this repository is very likely you already have it
  • GO Programming Language must be installed. Minimum required version is 1.20
  • GNU CC Compiler at least version 13 (is highly suggested that you install chocolatey package manager - see following point)
  • If you need to build MDBX tools (i.e. .\wmake.ps1 db-tools) then Chocolatey package manager for Windows must be installed. By Chocolatey you need to install the following components : cmake, make, mingw by choco install cmake make mingw. Make sure Windows System "Path" variable has: C:\ProgramData\chocolatey\lib\mingw\tools\install\mingw64\bin

  Important note about Anti-Viruses During MinGW's compiler detection phase some temporary executables are generated to test compiler capabilities. It's been reported some anti-virus programs detect those files as possibly infected by Win64/Kryptic.CIS trojan horse (or a variant of it). Although those are false positives we have no control over 100+ vendors of security products for Windows and their respective detection algorithms and we understand this might make your experience with Windows builds uncomfortable. To workaround the issue you might either set exclusions for your antivirus specifically for build\bin\mdbx\CMakeFiles sub-folder of the cloned repo or you can run erigon using the following other two options

• Use Docker : see docker-compose.yml

• Use WSL (Windows Subsystem for Linux) strictly on version 2. Under this option you can build Erigon just as you would on a regular Linux distribution. You can point your data also to any of the mounted Windows partitions ( eg. /mnt/c/[...], /mnt/d/[...] etc) but in such case be advised performance is impacted: this is due to the fact those mount points use DrvFS which is a network file system and, additionally, MDBX locks the db for exclusive access which implies only one process at a time can access data. This has consequences on the running of rpcdaemon which has to be configured as Remote DB even if it is executed on the very same computer. If instead your data is hosted on the native Linux filesystem non limitations apply. Please also note the default WSL2 environment has its own IP address which does not match the one of the network interface of Windows host: take this into account when configuring NAT for port 30303 on your router.

Using TOML or YAML Config Files

You can set Erigon flags through a YAML or TOML configuration file with the flag --config. The flags set in the configuration file can be overwritten by writing the flags directly on Erigon command line

Example

./build/bin/erigon --config ./config.yaml --chain=goerli

Assuming we have chain : "mainnet" in our configuration file, by adding --chain=goerli allows the overwrite of the flag inside of the yaml configuration file and sets the chain to goerli

TOML

Example of setting up TOML config file

datadir = 'your datadir'
port = 1111
chain = "mainnet"
http = true
"private.api.addr"="localhost:9090"

"http.api" = ["eth","debug","net"]

YAML

Example of setting up a YAML config file

datadir : 'your datadir'
port : 1111
chain : "mainnet"
http : true
private.api.addr : "localhost:9090"

http.api : ["eth","debug","net"]

Beacon Chain (Consensus Layer)

Erigon can be used as an Execution Layer (EL) for Consensus Layer clients (CL). Default configuration is OK.

If your CL client is on a different device, add --authrpc.addr 0.0.0.0 (Engine API listens on localhost by default) as well as --authrpc.vhosts <CL host> where <CL host> is your source host or any.

In order to establish a secure connection between the Consensus Layer and the Execution Layer, a JWT secret key is automatically generated.

The JWT secret key will be present in the datadir by default under the name of jwt.hex and its path can be specified with the flag --authrpc.jwtsecret.

This piece of info needs to be specified in the Consensus Layer as well in order to establish connection successfully. More information can be found here.

Once Erigon is running, you need to point your CL client to <erigon address>:8551, where <erigon address> is either localhost or the IP address of the device running Erigon, and also point to the JWT secret path created by Erigon.

Caplin

Caplin is a full-fledged validating Consensus Client like Prysm, Lighthouse, Teku, Nimbus and Lodestar. Its goal is:

• provide better stability
• Validation of the chain
• Stay in sync
• keep the execution of blocks on chain tip
• serve the Beacon API using a fast and compact data model alongside low CPU and memory usage.

The main reason why developed a new Consensus Layer is to experiment with the possible benefits that could come with it. For example, The Engine API does not work well with Erigon. The Engine API sends data one block at a time, which does not suit how Erigon works. Erigon is designed to handle many blocks simultaneously and needs to sort and process data efficiently. Therefore, it would be better for Erigon to handle the blocks independently instead of relying on the Engine API.

Caplin's Usage.

Caplin can be enabled through the --internalcl flag. from that point on, an external Consensus Layer will not be need anymore.

Caplin also has an archivial mode for historical states and blocks. it can be enabled through the --caplin.archive flag. In order to enable the caplin's Beacon API, the flag --beacon.api=<namespaces> must be added. e.g: --beacon.api=beacon,builder,config,debug,node,validator,lighthouse will enable all endpoints. **NOTE: Caplin is not staking-ready so aggregation endpoints are still to be implemented. Additionally enabling the Beacon API will lead to a 6 GB higher RAM usage.

Multiple Instances / One Machine

Define 6 flags to avoid conflicts: --datadir --port --http.port --authrpc.port --torrent.port --private.api.addr. Example of multiple chains on the same machine:

# mainnet
./build/bin/erigon --datadir="<your_mainnet_data_path>" --chain=mainnet --port=30303 --http.port=8545 --authrpc.port=8551 --torrent.port=42069 --private.api.addr=127.0.0.1:9090 --http --ws --http.api=eth,debug,net,trace,web3,erigon


# sepolia
./build/bin/erigon --datadir="<your_sepolia_data_path>" --chain=sepolia --port=30304 --http.port=8546 --authrpc.port=8552 --torrent.port=42068 --private.api.addr=127.0.0.1:9091 --http --ws --http.api=eth,debug,net,trace,web3,erigon

Dev Chain

🔬 Detailed explanation is DEV_CHAIN.

Key features

🔬 See more detailed overview of functionality and current limitations. It is being updated on recurring basis.

More Efficient State Storage

Flat KV storage. Erigon uses a key-value database and storing accounts and storage in a simple way.

🔬 See our detailed DB walkthrough here.

Preprocessing. For some operations, Erigon uses temporary files to preprocess data before inserting it into the main DB. That reduces write amplification and DB inserts are orders of magnitude quicker.

🔬 See our detailed ETL explanation here.

Plain state.

Single accounts/state trie. Erigon uses a single Merkle trie for both accounts and the storage.

Faster Initial Sync

Erigon uses a rearchitected full sync algorithm from Go-Ethereum that is split into "stages".

🔬 See more detailed explanation in the Staged Sync Readme

It uses the same network primitives and is compatible with regular go-ethereum nodes that are using full sync, you do not need any special sync capabilities for Erigon to sync.

When reimagining the full sync, with focus on batching data together and minimize DB overwrites. That makes it possible to sync Ethereum mainnet in under 2 days if you have a fast enough network connection and an SSD drive.

Examples of stages are:

• Downloading headers;

• Downloading block bodies;

• Recovering senders' addresses;

• Executing blocks;

• Validating root hashes and building intermediate hashes for the state Merkle trie;

• [...]

JSON-RPC daemon

Most of Erigon's components (txpool, rpcdaemon, snapshots downloader, sentry, ...) can work inside Erigon and as independent process.

To enable built-in RPC server: --http and --ws (sharing same port with http)

Run RPCDaemon as separated process: this daemon can use local DB (with running Erigon or on snapshot of a database) or remote DB (run on another server). 🔬 See RPC-Daemon docs

For remote DB

This works regardless of whether RPC daemon is on the same computer with Erigon, or on a different one. They use TPC socket connection to pass data between them. To use this mode, run Erigon in one terminal window

make erigon
./build/bin/erigon --private.api.addr=localhost:9090 --http=false
make rpcdaemon
./build/bin/rpcdaemon --private.api.addr=localhost:9090 --http.api=eth,erigon,web3,net,debug,trace,txpool

gRPC ports

9090 erigon, 9091 sentry, 9092 consensus engine, 9093 torrent downloader, 9094 transactions pool

Supported JSON-RPC calls (eth, debug , net, web3):

For a details on the implementation status of each command, see this table.

Run all components by docker-compose

Docker allows for building and running Erigon via containers. This alleviates the need for installing build dependencies onto the host OS.

Optional: Setup dedicated user

User UID/GID need to be synchronized between the host OS and container so files are written with correct permission.

You may wish to setup a dedicated user/group on the host OS, in which case the following make targets are available.

# create "erigon" user
make user_linux
# or
make user_macos

Environment Variables

There is a .env.example file in the root of the repo.

• DOCKER_UID - The UID of the docker user
• DOCKER_GID - The GID of the docker user
• XDG_DATA_HOME - The data directory which will be mounted to the docker containers

If not specified, the UID/GID will use the current user.

A good choice for XDG_DATA_HOME is to use the ~erigon/.ethereum directory created by helper targets make user_linux or make user_macos.

Check: Permissions

In all cases, XDG_DATA_HOME (specified or default) must be writeable by the user UID/GID in docker, which will be determined by the DOCKER_UID and DOCKER_GID at build time.

If a build or service startup is failing due to permissions, check that all the directories, UID, and GID controlled by these environment variables are correct.

Run

Next command starts: Erigon on port 30303, rpcdaemon on port 8545, prometheus on port 9090, and grafana on port 3000.

#
# Will mount ~/.local/share/erigon to /home/erigon/.local/share/erigon inside container
#
make docker-compose

#
# or
#
# if you want to use a custom data directory
# or, if you want to use different uid/gid for a dedicated user
#
# To solve this, pass in the uid/gid parameters into the container.
#
# DOCKER_UID: the user id
# DOCKER_GID: the group id
# XDG_DATA_HOME: the data directory (default: ~/.local/share)
#
# Note: /preferred/data/folder must be read/writeable on host OS by user with UID/GID given
#       if you followed above instructions
#
# Note: uid/gid syntax below will automatically use uid/gid of running user so this syntax
#       is intended to be run via the dedicated user setup earlier
#
DOCKER_UID=$(id -u) DOCKER_GID=$(id -g) XDG_DATA_HOME=/preferred/data/folder DOCKER_BUILDKIT=1 COMPOSE_DOCKER_CLI_BUILD=1 make docker-compose

#
# if you want to run the docker, but you are not logged in as the $ERIGON_USER
# then you'll need to adjust the syntax above to grab the correct uid/gid
#
# To run the command via another user, use
#
ERIGON_USER=erigon
sudo -u ${ERIGON_USER} DOCKER_UID=$(id -u ${ERIGON_USER}) DOCKER_GID=$(id -g ${ERIGON_USER}) XDG_DATA_HOME=~${ERIGON_USER}/.ethereum DOCKER_BUILDKIT=1 COMPOSE_DOCKER_CLI_BUILD=1 make docker-compose

Makefile creates the initial directories for erigon, prometheus and grafana. The PID namespace is shared between erigon and rpcdaemon which is required to open Erigon's DB from another process (RPCDaemon local-mode). See: https://github.com/ledgerwatch/erigon/pull/2392/files

If your docker installation requires the docker daemon to run as root (which is by default), you will need to prefix the command above with sudo. However, it is sometimes recommended running docker (and therefore its containers) as a non-root user for security reasons. For more information about how to do this, refer to this article.

Windows support for docker-compose is not ready yet. Please help us with .ps1 port.

Default Ports and Firewalls

erigon ports

Component	Port	Protocol	Purpose	Should Expose
engine	9090	TCP	gRPC Server	Private
engine	42069	TCP & UDP	Snap sync (Bittorrent)	Public
engine	8551	TCP	Engine API (JWT auth)	Private
sentry	30303	TCP & UDP	eth/68 peering	Public
sentry	30304	TCP & UDP	eth/67 peering	Public
sentry	9091	TCP	incoming gRPC Connections	Private
rpcdaemon	8545	TCP	HTTP & WebSockets & GraphQL	Private

Typically, 30303 and 30304 are exposed to the internet to allow incoming peering connections. 9090 is exposed only internally for rpcdaemon or other connections, (e.g. rpcdaemon -> erigon). Port 8551 (JWT authenticated) is exposed only internally for Engine API JSON-RPC queries from the Consensus Layer node.

caplin ports

Component	Port	Protocol	Purpose	Should Expose
sentinel	4000	UDP	Peering	Public
sentinel	4001	TCP	Peering	Public

If you are using --internalcl aka caplin as your consensus client, then also look at the chart above

beaconAPI ports

Component	Port	Protocol	Purpose	Should Expose
REST	5555	TCP	REST	Public

If you are using --internalcl aka caplin as your consensus client and --beacon.api then also look at the chart above

shared ports

Component	Port	Protocol	Purpose	Should Expose
all	6060	TCP	pprof	Private
all	6060	TCP	metrics	Private

Optional flags can be enabled that enable pprof or metrics (or both) - however, they both run on 6060 by default, so

you'll have to change one if you want to run both at the same time. use --help with the binary for more info.

How to run erigon as a separate user? (e.g. as a systemd daemon)

Running erigon from build/bin as a separate user might produce an error:

error while loading shared libraries: libsilkworm_capi.so: cannot open shared object file: No such file or directory

The library needs to be installed for another user using make DIST=<path> install. You could use $HOME/erigon or /opt/erigon as the installation path, for example:

make DIST=/opt/erigon install

and then run /opt/erigon/erigon.

Docker permissions error

Docker uses user erigon with UID/GID 1000 (for security reasons). You can see this user being created in the Dockerfile. Can fix by giving a host's user ownership of the folder, where the host's user UID/GID is the same as the docker's user UID/GID (1000). More details in post

Known issues

htop shows incorrect memory usage

Erigon's internal DB (MDBX) using MemoryMap - when OS does manage all read, write, cache operations instead of Application (linux , windows)

htop on column res shows memory of "App + OS used to hold page cache for given App", but it's not informative, because if htop says that app using 90% of memory you still can run 3 more instances of app on the same machine - because most of that 90% is "OS pages cache". OS automatically frees this cache any time it needs memory. Smaller "page cache size" may not impact performance of Erigon at all.

Next tools show correct memory usage of Erigon:

• vmmap -summary PID | grep -i "Physical footprint". Without grep you can see details

  • section MALLOC ZONE column Resident Size shows App memory usage, section REGION TYPE column Resident Size shows OS pages cache size.

• Prometheus dashboard shows memory of Go app without OS pages cache (make prometheus, open in browser localhost:3000, credentials admin/admin)

• cat /proc/<PID>/smaps

  Erigon uses ~4Gb of RAM during genesis sync and ~1Gb during normal work. OS pages cache can utilize unlimited amount of memory.

  Warning: Multiple instances of Erigon on same machine will touch Disk concurrently, it impacts performance - one of main Erigon optimisations: "reduce Disk random access". "Blocks Execution stage" still does many random reads - this is reason why it's slowest stage. We do not recommend running multiple genesis syncs on same Disk. If genesis sync passed, then it's fine to run multiple Erigon instances on same Disk.

Blocks Execution is slow on cloud-network-drives

Please read erigontech#1516 (comment) In short: network-disks are bad for blocks execution - because blocks execution reading data from db non-parallel non-batched way.

Filesystem's background features are expensive

For example: btrfs's autodefrag option - may increase write IO 100x times
