Usage: $(basename "$0") [OPTIONS] -- [BEACON NODE OPTIONS]
E.g.: $(basename "$0") --nodes ${NUM_NODES} --stop-at-epoch 5 --data-dir "${DATA_DIR}" # defaults
CI run: $(basename "$0") --disable-htop -- --verify-finalization
-h, --help show this help message
-n, --nodes number of nodes to launch (default: ${NUM_NODES})
-g, --with-ganache simulate a genesis event based on a deposit contract
-s, --stop-at-epoch stop simulation at epoch (default: infinite)
-d, --data-dir directory where all the node data and logs will end up
(default: "${DATA_DIR}")
--preset Const preset to be (default: mainnet)
--base-port bootstrap node's Eth2 traffic port (default: ${BASE_PORT})
--base-rest-port bootstrap node's REST port (default: ${BASE_REST_PORT})
--base-metrics-port bootstrap node's metrics port (default: ${BASE_METRICS_PORT})
--base-vc-metrics-port The first validator client metrics port (default: ${BASE_VC_METRICS_PORT})
--base-remote-signer-port first remote signing node's port (default: ${BASE_REMOTE_SIGNER_PORT})
--base-el-net-port first EL's network traffic port (default: ${BASE_EL_NET_PORT})
--base-el-http-port first EL's HTTP web3 port (default: ${BASE_EL_HTTP_PORT})
--base-el-ws-port first EL's WebSocket web3 port (default: ${BASE_EL_WS_PORT})
--base-el-auth-rpc-port first EL's authenticated engine API port (default: ${BASE_EL_AUTH_RPC_PORT})
--el-port-offset offset to apply between ports of multiple ELs (default: ${EL_PORT_OFFSET})
--disable-htop don't use "htop" to see the nimbus_beacon_node processes
--disable-vc don't use validator client binaries for validators
(by default validators are split 50/50 between beacon nodes
and validator clients, with all beacon nodes being paired up
with a corresponding validator client)
--lighthouse-vc-nodes number of Lighthouse VC nodes (assigned before Nimbus VC nodes, default: ${LIGHTHOUSE_VC_NODES})
--enable-logtrace display logtrace analysis
--log-level set the log level (default: "${LOG_LEVEL}")
--reuse-existing-data-dir instead of deleting and recreating the data dir, keep it and reuse everything we can from it
--reuse-binaries don't (re)build the binaries we need and don't delete them at the end (speeds up testing)
--timeout timeout in seconds (default: ${TIMEOUT_DURATION} - no timeout)
--kill-old-processes if any process is found listening on a port we use, kill it (default: disabled)
--eth2-docker-image use docker image instead of compiling the beacon node
--remote-validators-count number of remote validators which will be generated
--threshold used by a threshold secret sharing mechanism and determine how many shares are need to
restore signature of the original secret key
--remote-signers number of remote signing nodes
--light-clients number of light clients
--run-nimbus-el Run nimbush-eth1 as EL
--run-geth Run geth EL clients
--dl-geth Download geth binary if not found
--dl-eth2 Download Nimbus CL binary
--verbose Verbose output
