Associated Types

`type Event: From<Event> + Into<Self::Event>`

The event type of this module.

`type Call: From<Call<Self>>`

The function call.

`type KeyOwnerProof: Parameter + GetSessionNumber + GetValidatorCount`

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`

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

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

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>`

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 pallet's ValidateUnsigned in the runtime definition.

`type WeightInfo: WeightInfo`

Weights for this pallet.
