Release Notes and Binaries

Build 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/erigontech/erigon.git
cd erigon
make erigon
./build/bin/erigon

Increase download speed by --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, and --chain=amoy for Polygon Amoy. For Gnosis Chain you need a Consensus Layer client alongside Erigon (https://docs.gnosischain.com/category/step--3---run-consensus-client).

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

datadir        
    chaindata     # "Recently-updated Latest State", "Recent History", "Recent Blocks"
    snapshots     # contains `.seg` files - it's old blocks
        domain    # Latest State
        history   # Historical values 
        idx       # InvertedIndices: can search/filtering/union/intersect them - to find historical data. like eth_getLogs or trace_transaction
        accessors # Additional (generated) indices of history - have "random-touch" read-pattern. They can serve only `Get` requests (no search/filters).
    txpool        # pending transactions. safe to remove.
    nodes         # p2p peers. safe to remove.
    temp          # used to sort data bigger than RAM. can grow to ~100gb. cleaned at startup.
   
# There is 4 domains: account, storage, code, commitment 

If you can afford store datadir on 1 nvme-raid - great. If can't - it's possible to store history on cheap drive.

# place (or ln -s) `datadir` on slow disk. link some sub-folders to fast (low-latency) disk.
# Example: what need link to fast disk to speedup execution
datadir        
    chaindata   # link to fast disk
    snapshots   
        domain    # link to fast disk
        history   
        idx       
        accessors 
    temp # buffers to sort data >> RAM. sequential-buffered IO - is slow-disk-friendly   

# Example: how to speedup history access: 
#   - go step-by-step - first try store `accessors` on fast disk
#   - if speed is not good enough: `idx`
#   - if still not enough: `history`

• Initial sync doesn't re-exec from 0: downloading 99% LatestState and History
• Per-Transaction granularity of history (Erigon2 had per-block). Means:
  • Can execute 1 historical transaction - without executing it's block
  • If account X change V1->V2->V1 within 1 block (different transactions): debug_getModifiedAccountsByNumber return it
  • Erigon3 doesn't store Logs (aka Receipts) - it always re-executing historical txn (but it's cheaper)
• Validator mode: added. --internalcl is enabled by default. to disable use --externalcl.
• Store most of data in immutable files (segments/snapshots):
  • can symlink/mount latest state to fast drive and history to cheap drive
  • chaindata is less than 15gb. It's ok to rm -rf chaindata. (to prevent grow: recommend --batchSize <= 1G)
• --prune flags changed: see --prune.mode (default: archive, full: full, EIP-4444: minimal)
• Other changes:
  • ExecutionStage included many E2 stages: stage_hash_state, stage_trie, log_index, history_index, trace_index
  • Restart doesn't loose much partial progress: --sync.loop.block.limit=5_000 enabled by default

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.

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. Each service has own ./cmd/*/README.md file. Erigon Blog.

Built-in consensus for Ethereum Mainnet, Sepolia, Holesky, Gnosis. To use external Consensus Layer: --externalcl.

If you would like to give Erigon a try: a good option is to start syncing one of the public testnets, Holesky (or Amoy). It syncs much quicker, and does not take so much disk space:

git clone https://github.com/erigontech/erigon.git
cd erigon
make erigon
./build/bin/erigon --datadir=<your_datadir> --chain=holesky --prune.mode=full

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

Block production is fully supported for Ethereum & Gnosis Chain. It is still experimental for Polygon.

You can set Erigon flags through a 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

./build/bin/erigon --config ./config.toml --chain=sepolia

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

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

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

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 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 is be enabled by default. to disable it and enable the Engine API, use the --externalcl 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.

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

On good network bandwidth EthereumMainnet FullNode syncs in 3 hours: OtterSync can sync

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.

🔬 Staged Sync Readme

Most of Erigon's components (txpool, rpcdaemon, snapshots downloader, sentry, ...) can work inside Erigon and as independent process on same Server (or another Server). Example:

make erigon rpcdaemon
./build/bin/erigon --datadir=/my --http=false
# To run RPCDaemon as separated process: use same `--datadir` as Erigon
./build/bin/rpcdaemon --datadir=/my --http.api=eth,erigon,web3,net,debug,trace,txpool --ws

• Supported JSON-RPC calls: eth, debug, net, web3
• increase throughput by: --rpc.batch.concurrency, --rpc.batch.limit, --db.read.concurrency
• increase throughput by disabling: --http.compression, --ws.compression

🔬 See RPC-Daemon docs

docker compose up prometheus grafana, detailed docs.

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.

In order to configure the ports, use:

   --caplin.discovery.addr value                                                    Address for Caplin DISCV5 protocol (default: "127.0.0.1")
   --caplin.discovery.port value                                                    Port for Caplin DISCV5 protocol (default: 4000)
   --caplin.discovery.tcpport value                                                 TCP Port for Caplin DISCV5 protocol (default: 4001)

Optional flags can be enabled that enable pprof or metrics (or both). Use --help with the binary for more info.

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

🔬 Detailed explanation is here.

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

• --txpool.nolocals=true
• don't add admin in --http.api list
• --http.corsdomain="*" is bad-practice: set exact hostname or IP
• protect from DOS by reducing: --rpc.batch.concurrency, --rpc.batch.limit

https://github.com/mathMakesArt/Erigon-on-RPi-4

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

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

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.

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/erigontech/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.

• on BorMainnet may help: --sync.loop.block.limit=10_000
• on cloud-drives (good throughput, bad latency) - can enable OS's brain to pre-fetch: SNAPSHOT_MADV_RND=false
• can lock latest state in RAM - to prevent from eviction (node may face high historical RPC traffic without impacting Chain-Tip perf):

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 1.22
  • 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.

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.

(Like gp3) You may read: #1516 (comment) In short: network-disks are bad for blocks execution - because blocks execution reading data from db non-parallel non-batched way. Tricks: if you throw anough RAM and set env variable ERIGON_SNAPSHOT_MADV_RND=false - then Erigon will work good-enough on Cloud drives - in cost of higher IO.

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

For anyone else that was getting the BuildKit error when trying to start Erigon the old way you can use the below...

XDG_DATA_HOME=/preferred/data/folder DOCKER_BUILDKIT=1 COMPOSE_DOCKER_CLI_BUILD=1 make docker-compose
