Expand description

Verifier for all blocks within an epoch with self-contained state.

Required methods

source

fn verify_light(&self, header: &Header) -> Result<(), M::Error>

Lightly verify the next block header. This may not be a header belonging to a different epoch.

Provided methods

source

fn verify_heavy(&self, header: &Header) -> Result<(), M::Error>

Perform potentially heavier checks on the next block header.

source

fn check_finality_proof(&self, _proof: &[u8 ]) -> Option<Vec<H256>>

Check a finality proof against this epoch verifier. Returns Some(hashes) if the proof proves finality of these hashes. Returns None if the proof doesn’t prove anything.
