pub struct EquivocationReportSystem<T, R, P, L>(/* private fields */);Expand description
BABE equivocation offence report system.
This type implements OffenceReportSystem such that:
- Equivocation reports are published on-chain as unsigned extrinsic via
offchain::CreateTransactionBase. - On-chain validity checks and processing are mostly delegated to the user provided generic
types implementing
KeyOwnerProofSystemandReportOffencetraits. - Offence reporter for unsigned transactions is fetched via the the authorship pallet.
