Erigon

Erigon is an implementation of Ethereum (aka "Ethereum client"), on the efficiency frontier, written in Go.

Build status

NB! In-depth links are marked by the microscope sign (🔬)

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.

System Requirements

Recommend 2Tb storage space on a single partition: 1.3Tb state, 200GB temp files (can symlink or mount folder <datadir>/etl-tmp to another disk).

RAM: 16GB, 64-bit architecture, Golang version >= 1.16

🔬 more info on disk storage is here)

Usage

Getting Started
git clone --recurse-submodules -j8 https://github.com/ledgerwatch/erigon.git
cd erigon
make erigon
./build/bin/erigon
Testnets

If you would like to give Erigon a try, but do not have spare 2Tb on your driver, 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 goerli --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.

Mining

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
  • RPCDaemon supports methods: eth_coinbase , eth_hashrate, eth_mining, eth_getWork, eth_submitWork, eth_submitHashrate
  • RPCDaemon supports websocket methods: newPendingTransaction
  • TODO:
    • we don't broadcast mined blocks to p2p-network yet, but it's easy to accomplish
    • eth_newPendingTransactionFilter
    • eth_newBlockFilter
    • eth_newFilter
    • websocket Logs

🔬 Detailed mining 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 1.16
    • GNU CC Compiler at least version 10 (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.

    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 algorythms and we understand this might make your experience with Windows builds uncomfortable. To workaround the issue you might either set exlusions 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.

Beacon Chain

Erigon can be used as an execution-layer for beacon chain consensus clients (Eth2). Default configuration is ok. Eth2 relies on availability of receipts - don't prune them: don't add character r to --prune flag. However, old receipes are not needed for Eth2 and you can safely prune them with --prune.r.before=11184524 in combination with --prune htc.

You must run the JSON-RPC daemon in addition to the Erigon.

If beacon chain client on a different device: add --http.addr 0.0.0.0 (JSON-RPC daemon listen on localhost by default) .

Once the JSON-RPC daemon is running, all you need to do is point your beacon chain client to <ip address>:8545, where is either localhost or the IP address of the device running the JSON-RPC daemon.

Erigon has been tested with Lighthouse however all other clients that support JSON-RPC should also work.

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

In Erigon RPC calls are extracted out of the main binary into a separate daemon. This daemon can use both local or remote DBs. That means, that this RPC daemon doesn't have to be running on the same machine as the main Erigon binary or it can run from a snapshot of a database for read-only calls.

🔬 See RPC-Daemon docs

For local DB

This is only possible if RPC daemon runs on the same computer as Erigon. This mode uses shared memory access to the database of Erigon, which has better performance than accessing via TPC socket (see "For remote DB" section below). Provide both --datadir and --private.api.addr options:

make erigon
./build/bin/erigon --private.api.addr=localhost:9090
make rpcdaemon
./build/bin/rpcdaemon --datadir=<your_data_dir> --private.api.addr=localhost:9090 --http.api=eth,erigon,web3,net,debug,trace,txpool
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
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 snapshot downloader, 9094 TxPool

Default Ports and Protocols / Firewalls?
erigon ports
Port Protocol Purpose Expose
30303 TCP & UDP eth/66 peering Public
9090 TCP gRPC Connections 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)

rpcdaemon ports
Port Protocol Purpose Expose
8545 TCP HTTP & WebSockets Private

Typically 8545 is exposed only interally for JSON-RPC queries. Both HTTP and WebSocket connections are on the same port.

sentry ports
Port Protocol Purpose Expose
30303 TCP & UDP Peering Public
9091 TCP gRPC Connections Private

Typically a sentry process will run one eth/xx protocl (e.g. eth/66) and will be exposed to the internet on 30303. Port 9091 is for internal gRCP connections (e.g erigon -> sentry)

Other ports
Port Protocol Purpose Expose
6060 TCP pprof Private
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.

Reserved for future use: gRPC ports: 9092 consensus engine, 9093 snapshot downloader, 9094 TxPool

How to get diagnostic for bug report?

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 free 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 much random reads - this is reason why it's slowest stage. We do not recommend run multiple genesis syncs on same Disk. If genesis sync passed, then it's fine to run multiple Erigon on same Disk.

Blocks Execution is slow on cloud-network-drives

Please read https://github.com/ledgerwatch/erigon/issues/1516#issuecomment-811958891 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

NotFound is returned by API methods if the requested item does not exist.

Functions

This section is empty.

Types

type CallMsg

type CallMsg struct {
	From     common.Address  // the sender of the 'transaction'
	To       *common.Address // the destination contract (nil for contract creation)
	Gas      uint64          // if 0, the call executes with near-infinite gas
	GasPrice *uint256.Int    // wei <-> gas exchange ratio
	Value    *uint256.Int    // amount of wei sent along with the call
	Data     []byte          // input data, usually an ABI-encoded contract method invocation

	FeeCap     *uint256.Int     // EIP-1559 fee cap per gas.
	Tip        *uint256.Int     // EIP-1559 tip per gas.
	AccessList types.AccessList // EIP-2930 access list.
}

CallMsg contains parameters for contract calls.

type ChainReader

type ChainReader interface {
	BlockByHash(ctx context.Context, hash common.Hash) (*types.Block, error)
	BlockByNumber(ctx context.Context, number *big.Int) (*types.Block, error)
	HeaderByHash(ctx context.Context, hash common.Hash) (*types.Header, error)
	HeaderByNumber(ctx context.Context, number *big.Int) (*types.Header, error)
	TransactionCount(ctx context.Context, blockHash common.Hash) (uint, error)
	TransactionInBlock(ctx context.Context, blockHash common.Hash, index uint) (*types.Transaction, error)

	// This method subscribes to notifications about changes of the head block of
	// the canonical chain.
	SubscribeNewHead(ctx context.Context, ch chan<- *types.Header) (Subscription, error)
}

ChainReader provides access to the blockchain. The methods in this interface access raw data from either the canonical chain (when requesting by block number) or any blockchain fork that was previously downloaded and processed by the node. The block number argument can be nil to select the latest canonical block. Reading block headers should be preferred over full blocks whenever possible.

The returned error is NotFound if the requested item does not exist.

type ChainStateReader

type ChainStateReader interface {
	BalanceAt(ctx context.Context, account common.Address, blockNumber *big.Int) (*big.Int, error)
	StorageAt(ctx context.Context, account common.Address, key common.Hash, blockNumber *big.Int) ([]byte, error)
	CodeAt(ctx context.Context, account common.Address, blockNumber *big.Int) ([]byte, error)
	NonceAt(ctx context.Context, account common.Address, blockNumber *big.Int) (uint64, error)
}

ChainStateReader wraps access to the state trie of the canonical blockchain. Note that implementations of the interface may be unable to return state values for old blocks. In many cases, using CallContract can be preferable to reading raw contract storage.

type ChainSyncReader

type ChainSyncReader interface {
	SyncProgress(ctx context.Context) (*SyncProgress, error)
}

ChainSyncReader wraps access to the node's current sync status. If there's no sync currently running, it returns nil.

type ContractCaller

type ContractCaller interface {
	CallContract(ctx context.Context, call CallMsg, blockNumber *big.Int) ([]byte, error)
}

A ContractCaller provides contract calls, essentially transactions that are executed by the EVM but not mined into the blockchain. ContractCall is a low-level method to execute such calls. For applications which are structured around specific contracts, the abigen tool provides a nicer, properly typed way to perform calls.

type FilterQuery

type FilterQuery struct {
	BlockHash *common.Hash     // used by eth_getLogs, return logs only from block with this hash
	FromBlock *big.Int         // beginning of the queried range, nil means genesis block
	ToBlock   *big.Int         // end of the range, nil means latest block
	Addresses []common.Address // restricts matches to events created by specific contracts

	// The Topic list restricts matches to particular event topics. Each event has a list
	// of topics. Topics matches a prefix of that list. An empty element slice matches any
	// topic. Non-empty elements represent an alternative that matches any of the
	// contained topics.
	//
	// Examples:
	// {} or nil          matches any topic list
	// {{A}}              matches topic A in first position
	// {{}, {B}}          matches any topic in first position AND B in second position
	// {{A}, {B}}         matches topic A in first position AND B in second position
	// {{A, B}, {C, D}}   matches topic (A OR B) in first position AND (C OR D) in second position
	Topics [][]common.Hash
}

FilterQuery contains options for contract log filtering.

type GasEstimator

type GasEstimator interface {
	EstimateGas(ctx context.Context, call CallMsg) (uint64, error)
}

GasEstimator wraps EstimateGas, which tries to estimate the gas needed to execute a specific transaction based on the pending state. There is no guarantee that this is the true gas limit requirement as other transactions may be added or removed by miners, but it should provide a basis for setting a reasonable default.

type GasPricer

type GasPricer interface {
	SuggestGasPrice(ctx context.Context) (*big.Int, error)
}

GasPricer wraps the gas price oracle, which monitors the blockchain to determine the optimal gas price given current fee market conditions.

type LogFilterer

type LogFilterer interface {
	FilterLogs(ctx context.Context, q FilterQuery) ([]types.Log, error)
	SubscribeFilterLogs(ctx context.Context, q FilterQuery, ch chan<- types.Log) (Subscription, error)
}

LogFilterer provides access to contract log events using a one-off query or continuous event subscription.

Logs received through a streaming query subscription may have Removed set to true, indicating that the log was reverted due to a chain reorganisation.

type PendingContractCaller

type PendingContractCaller interface {
	PendingCallContract(ctx context.Context, call CallMsg) ([]byte, error)
}

PendingContractCaller can be used to perform calls against the pending state.

type PendingStateEventer

type PendingStateEventer interface {
	SubscribePendingTransactions(ctx context.Context, ch chan<- *types.Transaction) (Subscription, error)
}

A PendingStateEventer provides access to real time notifications about changes to the pending state.

type PendingStateReader

type PendingStateReader interface {
	PendingBalanceAt(ctx context.Context, account common.Address) (*big.Int, error)
	PendingStorageAt(ctx context.Context, account common.Address, key common.Hash) ([]byte, error)
	PendingCodeAt(ctx context.Context, account common.Address) ([]byte, error)
	PendingNonceAt(ctx context.Context, account common.Address) (uint64, error)
	PendingTransactionCount(ctx context.Context) (uint, error)
}

A PendingStateReader provides access to the pending state, which is the result of all known executable transactions which have not yet been included in the blockchain. It is commonly used to display the result of ’unconfirmed’ actions (e.g. wallet value transfers) initiated by the user. The PendingNonceAt operation is a good way to retrieve the next available transaction nonce for a specific account.

type Subscription

type Subscription interface {
	// Unsubscribe cancels the sending of events to the data channel
	// and closes the error channel.
	Unsubscribe()
	// Err returns the subscription error channel. The error channel receives
	// a value if there is an issue with the subscription (e.g. the network connection
	// delivering the events has been closed). Only one value will ever be sent.
	// The error channel is closed by Unsubscribe.
	Err() <-chan error
}

Subscription represents an event subscription where events are delivered on a data channel.

type SyncProgress

type SyncProgress struct {
	StartingBlock uint64 // Block number where sync began
	CurrentBlock  uint64 // Current block number where sync is at
	HighestBlock  uint64 // Highest alleged block number in the chain
	PulledStates  uint64 // Number of state trie entries already downloaded
	KnownStates   uint64 // Total number of state trie entries known about
}

SyncProgress gives progress indications when the node is synchronising with the Ethereum network.

type TransactionReader

type TransactionReader interface {
	// TransactionByHash checks the pool of pending transactions in addition to the
	// blockchain. The isPending return value indicates whether the transaction has been
	// mined yet. Note that the transaction may not be part of the canonical chain even if
	// it's not pending.
	TransactionByHash(ctx context.Context, txHash common.Hash) (tx *types.Transaction, isPending bool, err error)
	// TransactionReceipt returns the receipt of a mined transaction. Note that the
	// transaction may not be included in the current canonical chain even if a receipt
	// exists.
	TransactionReceipt(ctx context.Context, txHash common.Hash) (*types.Receipt, error)
}

TransactionReader provides access to past transactions and their receipts. Implementations may impose arbitrary restrictions on the transactions and receipts that can be retrieved. Historic transactions may not be available.

Avoid relying on this interface if possible. Contract logs (through the LogFilterer interface) are more reliable and usually safer in the presence of chain reorganisations.

The returned error is NotFound if the requested item does not exist.

type TransactionSender

type TransactionSender interface {
	SendTransaction(ctx context.Context, tx *types.Transaction) error
}

TransactionSender wraps transaction sending. The SendTransaction method injects a signed transaction into the pending transaction pool for execution. If the transaction was a contract creation, the TransactionReceipt method can be used to retrieve the contract address after the transaction has been mined.

The transaction must be signed and have a valid nonce to be included. Consumers of the API can use package accounts to maintain local private keys and need can retrieve the next available nonce using PendingNonceAt.
