Ethereum 2.0 client by Sigma Prime. Provides a full-featured beacon node, a
validator client and utilities for managing validator accounts.
Usage: lighthouse [OPTIONS] [COMMAND]
Commands:
account_manager
Utilities for generating and managing Ethereum 2.0 accounts. [aliases:
a, am, account]
beacon_node
The primary component which connects to the Ethereum 2.0 P2P network
and downloads, verifies and stores blocks. Provides a HTTP API for
querying the beacon chain and publishing messages to the network.
[aliases: b, bn, beacon]
boot_node
Start a special Lighthouse process that only serves as a discv5
boot-node. This process will *not* import blocks or perform most
typical beacon node functions. Instead, it will simply run the discv5
service and assist nodes on the network to discover each other. This
is the recommended way to provide a network boot-node since it has a
reduced attack surface compared to a full beacon node.
database_manager
Manage a beacon node database. [aliases: db]
validator_client
When connected to a beacon node, performs the duties of a staked
validator (e.g., proposing blocks and attestations). [aliases: v, vc,
validator]
validator_manager
Utilities for managing a Lighthouse validator client via the HTTP API.
[aliases: vm, validator-manager]
help
Print this message or the help of the given subcommand(s)
Options:
-d, --datadir <DIR>
Used to specify a custom root data directory for lighthouse keys and
databases. Defaults to $HOME/.lighthouse/{network} where network is
the value of the `network` flag Note: Users should specify separate
custom datadirs for different networks.
--debug-level <LEVEL>
Specifies the verbosity level used when emitting logs to the terminal.
[default: info] [possible values: info, debug, trace, warn, error]
--genesis-state-url <URL>
A URL of a beacon-API compatible server from which to download the
genesis state. Checkpoint sync server URLs can generally be used with
this flag. If not supplied, a default URL or the --checkpoint-sync-url
may be used. If the genesis state is already included in this binary
then this value will be ignored.
--genesis-state-url-timeout <SECONDS>
The timeout in seconds for the request to --genesis-state-url.
[default: 300]
--log-format <FORMAT>
Specifies the log format used when emitting logs to the terminal.
[possible values: JSON]
--logfile-debug-level <LEVEL>
The verbosity level used when emitting logs to the log file. [default:
debug] [possible values: info, debug, trace, warn, error]
--logfile-dir <DIR>
Directory path where the log file will be stored
--logfile-format <FORMAT>
Specifies the log format used when emitting logs to the logfile.
[possible values: DEFAULT, JSON]
--logfile-max-number <COUNT>
The maximum number of log files that will be stored. If set to 0,
background file logging is disabled. [default: 10]
--logfile-max-size <SIZE>
The maximum size (in MB) each log file can grow to before rotating. If
set to 0, background file logging is disabled. [default: 200]
--network <network>
Name of the Eth2 chain Lighthouse will sync and follow. [possible
values: mainnet, gnosis, chiado, sepolia, holesky, hoodi]
-t, --testnet-dir <DIR>
Path to directory containing eth2_testnet specs. Defaults to a
hard-coded Lighthouse testnet. Only effective if there is no existing
database.
--telemetry-collector-url <URL>
URL of the OpenTelemetry collector to export tracing spans (e.g.,
http://localhost:4317). If not set, tracing export is disabled.
--telemetry-service-name <NAME>
Override the OpenTelemetry service name. Defaults to 'lighthouse-bn'
for beacon node, 'lighthouse-vc' for validator client, or 'lighthouse'
for other subcommands.
-V, --version
Print version
Flags:
--disable-log-timestamp
If present, do not include timestamps in logging output.
--disable-malloc-tuning
If present, do not configure the system allocator. Providing this flag
will generally increase memory usage, it should only be provided when
debugging specific memory allocation issues.
-h, --help
Prints help information
--log-color [<log-color>]
Enables/Disables colors for logs in terminal. Set it to false to
disable colors. [default: true] [possible values: true, false]
--log-extra-info
If present, show module,file,line in logs
--logfile-color
Enables colors in logfile.
--logfile-compress
If present, compress old log files. This can help reduce the space
needed to store old logs.
--logfile-no-restricted-perms
If present, log files will be generated as world-readable meaning they
can be read by any user on the machine. Note that logs can often
contain sensitive information about your validator and so this flag
should be used with caution. For Windows users, the log file
permissions will be inherited from the parent folder.
--stdin-inputs
If present, read all user inputs from stdin instead of tty.
