Associated Types

type EpochDuration: Get<u64>[src]

The amount of time, in slots, that each epoch should last. NOTE: Currently it is not possible to change the epoch duration after the chain has started. Attempting to do so will brick block production.

type ExpectedBlockTime: Get<Self::Moment>[src]

The expected average block time at which BABE should be creating blocks. Since BABE is probabilistic it is not trivial to figure out what the expected average block time should be based on the slot duration and the security parameter c (where 1 - c represents the probability of a slot being empty).

type EpochChangeTrigger: EpochChangeTrigger[src]

BABE requires some logic to be triggered on every block to query for whether an epoch has ended and to perform the transition to the next epoch.

Typically, the ExternalTrigger type should be used. An internal trigger should only be used when no other module is responsible for changing authority set.

type KeyOwnerProof: Parameter + GetSessionNumber + GetValidatorCount[src]

The proof of key ownership, used for validating equivocation reports. The proof must include the session index and validator count of the session at which the equivocation occurred.

type KeyOwnerIdentification: Parameter[src]

The identification of a key owner, used when reporting equivocations.

type KeyOwnerProofSystem: KeyOwnerProofSystem<(KeyTypeId, AuthorityId), Proof = Self::KeyOwnerProof, IdentificationTuple = Self::KeyOwnerIdentification>[src]

A system for proving ownership of keys, i.e. that a given key was part of a validator set, needed for validating equivocation reports.

type HandleEquivocation: HandleEquivocation<Self>[src]

The equivocation handling subsystem, defines methods to report an offence (after the equivocation has been validated) and for submitting a transaction to report an equivocation (from an offchain context). NOTE: when enabling equivocation handling (i.e. this type isn’t set to ()) you must use this noble’s ValidateUnsigned in the runtime definition.

type WeightInfo: WeightInfo[src]
