Expand description

Configuration trait of this pallet.

Implement this type for a runtime in order to customize this pallet.

Required Associated Types§

The event type of this module.

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.

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

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

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.

Weights for this pallet.

Max Authorities in use

The maximum number of entries to keep in the set id to session index mapping.

Since the SetIdSession map is only used for validating equivocations this value should relate to the bonding duration of whatever staking system is being used (if any). If equivocation handling is not enabled then this value can be zero.
