/*
Package features defines which features are enabled for runtime
in order to selectively enable certain features to maintain a stable runtime.
The process for implementing new features using this package is as follows:
1. Add a new CMD flag in flags.go, and place it in the proper list(s) var for its client.
2. Add a condition for the flag in the proper Configure function(s) below.
3. Place any "new" behavior in the `if flagEnabled` statement.
4. Place any "previous" behavior in the `else` statement.
5. Ensure any tests using the new feature fail if the flag isn't enabled.
5a. Use the following to enable your flag for tests:
cfg := &featureconfig.Flags{
VerifyAttestationSigs: true,
}
resetCfg := featureconfig.InitWithReset(cfg)
defer resetCfg()
6. Add the string for the flags that should be running within E2E to E2EValidatorFlags
and E2EBeaconChainFlags.

PyrmontTestnet bool // PyrmontTestnet defines the flag through which we can enable the node to run on the Pyrmont testnet.
// Feature related flags.
RemoteSlasherProtection bool // RemoteSlasherProtection utilizes a beacon node with --slasher mode for validator slashing protection.
WriteSSZStateTransitions bool // WriteSSZStateTransitions to tmp directory.
SkipBLSVerify bool // Skips BLS verification across the runtime.
EnablePeerScorer bool // EnablePeerScorer enables experimental peer scoring in p2p.
EnableLargerGossipHistory bool // EnableLargerGossipHistory increases the gossip history we store in our caches.
WriteWalletPasswordOnWebOnboarding bool // WriteWalletPasswordOnWebOnboarding writes the password to disk after Prysm web signup.
DisableAttestingHistoryDBCache bool // DisableAttestingHistoryDBCache for the validator client increases disk reads/writes.
ProposerAttsSelectionUsingMaxCover bool // ProposerAttsSelectionUsingMaxCover enables max-cover algorithm when selecting attestations for proposing.
EnableOptimizedBalanceUpdate bool // EnableOptimizedBalanceUpdate uses an updated method of performing balance updates.
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
EnableGetBlockOptimizations bool // EnableGetBlockOptimizations optimizes some elements of the GetBlock() function.
EnableBatchVerification bool // EnableBatchVerification enables batch signature verification on gossip messages.
// Logging related toggles.
DisableGRPCConnectionLogs bool // Disables logging when a new grpc client has connected.
// Slasher toggles.
DisableLookback bool // DisableLookback updates slasher to not use the lookback and update validator histories until epoch 0.
DisableBroadcastSlashings bool // DisableBroadcastSlashings disables p2p broadcasting of proposer and attester slashings.
// Cache toggles.
EnableSSZCache bool // EnableSSZCache see https://github.com/prysmaticlabs/prysm/pull/4558.
EnableNextSlotStateCache bool // EnableNextSlotStateCache enables next slot state cache to improve validator performance.
EnableActiveBalanceCache bool // EnableActiveBalanceCache enables active balance cache.
// 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.
EnableSlasher bool // Enable slasher in the beacon node runtime.
// EnableSlashingProtectionPruning for the validator client.
EnableSlashingProtectionPruning bool
// Bug fixes related flags.
