Modules

• migrations
• pallet
  The pallet module in each FRAME pallet hosts the most important items needed to construct this pallet.

Structs

• CurrentBlockRandomnessDeprecated
  Randomness produced semi-freshly with each block, but inherits limitations of RandomnessFromTwoEpochsAgo from which it derives.
• EquivocationOffence
  BABE equivocation offence report.
• EquivocationReportSystem
  BABE equivocation offence report system.
• ExternalTrigger
  A type signifying to BABE that an external trigger for epoch changes (e.g. pallet-session) is used.
• ParentBlockRandomness
  Randomness produced semi-freshly with each block, but inherits limitations of RandomnessFromTwoEpochsAgo from which it derives.
• RandomnessFromOneEpochAgo
  Randomness usable by on-chain code that does not depend upon finality and takes action based upon on-chain commitments made during the previous epoch.
• RandomnessFromTwoEpochsAgo
  Randomness usable by consensus protocols that depend upon finality and take action based upon on-chain commitments made during the epoch before the previous epoch.
• SameAuthoritiesForever
  A type signifying to BABE that it should perform epoch changes with an internal trigger, recycling the same authorities forever.

Traits

• EpochChangeTrigger
  Trigger an epoch change, if any should take place.
• WeightInfo

Type Aliases

• AuthorityId
  A Babe authority identifier. Necessarily equivalent to the schnorrkel public key used in the main Babe module. If that ever changes, then this must, too.
