	EnableQUIC                          bool // EnableQUIC specifies whether to enable QUIC transport for libp2p.
	WriteWalletPasswordOnWebOnboarding  bool // WriteWalletPasswordOnWebOnboarding writes the password to disk after Prysm web signup.
	EnableDoppelGanger                  bool // EnableDoppelGanger enables doppelganger protection on startup for the validator.
	EnableHistoricalSpaceRepresentation bool // EnableHistoricalSpaceRepresentation enables the saving of registry validators in separate buckets to save space
	EnableBeaconRESTApi                 bool // EnableBeaconRESTApi enables experimental usage of the beacon REST API by the validator when querying a beacon node
	EnableExperimentalAttestationPool   bool // EnableExperimentalAttestationPool enables an experimental attestation pool design.
	DisableDutiesV2                     bool // DisableDutiesV2 sets validator client to use the get Duties endpoint
	EnableWeb                           bool // EnableWeb enables the webui on the validator client
	EnableStateDiff                     bool // EnableStateDiff enables the experimental state diff feature for the beacon node.

	// Logging related toggles.
	DisableGRPCConnectionLogs bool // Disables logging when a new grpc client has connected.
	EnableFullSSZDataLogging  bool // Enables logging for full ssz data on rejected gossip messages

	// Slasher toggles.
	DisableBroadcastSlashings bool // DisableBroadcastSlashings disables p2p broadcasting of proposer and attester slashings.

	// Bug fixes related flags.
	AttestTimely bool // AttestTimely fixes #8185. It is gated behind a flag to ensure beacon node's fix can safely roll out first. We'll invert this in v1.1.0.

	EnableSlashingProtectionPruning bool // Enable slashing protection pruning for the validator client.
	EnableMinimalSlashingProtection bool // Enable minimal slashing protection database for the validator client.

	SaveFullExecutionPayloads bool // Save full beacon blocks with execution payloads in the database.
	EnableStartOptimistic     bool // EnableStartOptimistic treats every block as optimistic at startup.

	DisableResourceManager     bool // Disables running the node with libp2p's resource manager.
	DisableStakinContractCheck bool // Disables check for deposit contract when proposing blocks
	IgnoreUnviableAttestations bool // Ignore attestations whose target state is not viable (avoids lagging-node DoS).

	EnableHashtree               bool // Enables usage of the hashtree library for hashing
	EnableVerboseSigVerification bool // EnableVerboseSigVerification specifies whether to verify individual signature if batch verification fails
	EnableProposerPreprocessing  bool // EnableProposerPreprocessing enables proposer pre-processing of blocks before proposing.

	PrepareAllPayloads bool // PrepareAllPayloads informs the engine to prepare a block on every slot.
	// BlobSaveFsync requires blob saving to block on fsync to ensure blobs are durably persisted before passing DA.
	BlobSaveFsync bool

	SaveInvalidBlock bool // SaveInvalidBlock saves invalid block to temp.
	SaveInvalidBlob  bool // SaveInvalidBlob saves invalid blob to temp.

	EnableDiscoveryReboot bool // EnableDiscoveryReboot allows the node to have its local listener to be rebooted in the event of discovery issues.

	// KeystoreImportDebounceInterval specifies the time duration the validator waits to reload new keys if they have
	// changed on disk. This feature is for advanced use cases only.
	KeystoreImportDebounceInterval time.Duration

	// AggregateIntervals specifies the time durations at which we aggregate attestations preparing for forkchoice.
	AggregateIntervals [3]time.Duration

	// Feature related flags (alignment forced in the end)
	ForceHead        string                // ForceHead forces the head block to be a specific block root, the last head block, or the last finalized block.
	BlacklistedRoots map[[32]byte]struct{} // BlacklistedRoots is a list of roots that are blacklisted from processing.
