Generates a proof of key ownership for the given authority in the current epoch. An example usage of this module is coupled with the session historical module to prove that a given authority key is tied to a given staking identity during a specific session. Proofs of key ownership are necessary for submitting equivocation reports. NOTE: even though the API takes a slot as parameter the current implementations ignores this parameter and instead relies on this method being called at the correct block height, i.e. any point at which the epoch for the given slot is live on-chain. Future implementations will instead use indexed data through an offchain worker, not requiring older states to be available.

Submits an unsigned extrinsic to report an equivocation. The caller must provide the equivocation proof and a key ownership proof (should be obtained using generate_key_ownership_proof). The extrinsic will be unsigned and should only be accepted for local authorship (not to be broadcast to the network). This method returns None when creation of the extrinsic fails, e.g. if equivocation reporting is disabled for the given runtime (i.e. this method is hardcoded to return None). Only useful in an offchain context.

Submits an unsigned extrinsic to report an equivocation. The caller must provide the equivocation proof and a key ownership proof (should be obtained using generate_key_ownership_proof). The extrinsic will be unsigned and should only be accepted for local authorship (not to be broadcast to the network). This method returns None when creation of the extrinsic fails, e.g. if equivocation reporting is disabled for the given runtime (i.e. this method is hardcoded to return None). Only useful in an offchain context.

fn generate_key_ownership_proof( &self, __runtime_api_at_param__: <Block as Block>::Hash, set_id: u64, authority_id: AuthorityId ) -> Result<Option<OpaqueKeyOwnershipProof>, ApiError>

Generates a proof of key ownership for the given authority in the given set. An example usage of this module is coupled with the session historical module to prove that a given authority key is tied to a given staking identity during a specific session. Proofs of key ownership are necessary for submitting equivocation reports. NOTE: even though the API takes a set_id as parameter the current implementations ignores this parameter and instead relies on this method being called at the correct block height, i.e. any point at which the given set id is live on-chain. Future implementations will instead use indexed data through an offchain worker, not requiring older states to be available.
