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.

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.

The caller must provide the double voting proof and a key ownership proof (should be obtained using generate_key_ownership_proof).

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 a fork voting equivocation. The caller must provide the fork voting proof (the ancestry proof should be obtained using generate_ancestry_proof) and a key ownership proof (should be obtained using generate_key_ownership_proof).

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 submit_report_future_block_voting_unsigned_extrinsic( &self, __runtime_api_at_param__: <Block as Block>::Hash, equivocation_proof: FutureBlockVotingProof<<<Block as Block>::Header as Header>::Number, AuthorityId>, key_owner_proof: OpaqueValue, ) -> Result<Option<()>, ApiError>

Submits an unsigned extrinsic to report a future block voting equivocation. The caller must provide the future block voting proof and a key ownership proof (should be obtained using generate_key_ownership_proof).

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.
