lighthouse --help
Lighthouse v2.3.0
Sigma Prime <[email protected]>
Ethereum 2.0 client by Sigma Prime. Provides a full-featured beacon node, a validator client and utilities for managing
validator accounts.

USAGE:
    lighthouse [FLAGS] [OPTIONS] [SUBCOMMAND]

FLAGS:
        --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.
    -l                             Enables environment logging giving access to sub-protocol logs such as discv5 and
                                   libp2p
    -h, --help                     Prints help information
        --logfile-compress         If present, compress old log files. This can help reduce the space needed to store
                                   old logs.
    -V, --version                  Prints version information

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, crit]
        --log-format <FORMAT>
            Specifies the log format used when emitting logs to the terminal. [possible values: JSON]

        --logfile <FILE>
            File path where the log file will be stored. Once it grows to the value specified in `--logfile-max-size` a
            new log file is generated where future logs are stored. Once the number of log files exceeds the value
            specified in `--logfile-max-number` the oldest log file will be overwritten.
        --logfile-debug-level <LEVEL>
            The verbosity level used when emitting logs to the log file. [default: debug]  [possible values:
            info, debug, trace, warn, error, crit]
        --logfile-max-number <COUNT>
            The maximum number of log files that will be stored. If set to 0, background file logging is disabled.
            [default: 5]
        --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, prater,
            gnosis, kiln, ropsten]
        --safe-slots-to-import-optimistically <INTEGER>
            Used to coordinate manual overrides of the SAFE_SLOTS_TO_IMPORT_OPTIMISTICALLY parameter. This flag should
            only be used if the user has a clear understanding that the broad Ethereum community has elected to override
            this parameter in the event of an attack at the PoS transition block. Incorrect use of this flag can cause
            your node to possibly accept an invalid chain or sync more slowly. Be extremely careful with this flag.
    -s, --spec <DEPRECATED>
            This flag is deprecated, it will be disallowed in a future release. This value is now derived from the
            --network or --testnet-dir flags.
        --terminal-block-hash-epoch-override <EPOCH>
            Used to coordinate manual overrides to the TERMINAL_BLOCK_HASH_ACTIVATION_EPOCH parameter. This flag should
            only be used if the user has a clear understanding that the broad Ethereum community has elected to override
            the terminal PoW block. Incorrect use of this flag will cause your node to experience a consensus
                                   failure. Be extremely careful with this flag.
        --terminal-block-hash-override <TERMINAL_BLOCK_HASH>
            Used to coordinate manual overrides to the TERMINAL_BLOCK_HASH parameter. This flag should only be used if
            the user has a clear understanding that the broad Ethereum community has elected to override the terminal
            PoW block. Incorrect use of this flag will cause your node to experience a consensus
                                   failure. Be extremely careful with this flag.
        --terminal-total-difficulty-override <INTEGER>
            Used to coordinate manual overrides to the TERMINAL_TOTAL_DIFFICULTY parameter. Accepts a 256-bit decimal
            integer (not a hex value). This flag should only be used if the user has a clear understanding that the
            broad Ethereum community has elected to override the terminal difficulty. Incorrect use of this flag will
            cause your node to experience a consensus
                                   failure. Be extremely careful with this flag.
    -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.

SUBCOMMANDS:
    account_manager     Utilities for generating and managing Ethereum 2.0 accounts. [aliases: a, am,
                        account, account_manager]
    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]
    help                Prints this message or the help of the given subcommand(s)
    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]
