Verify a justification of a block

Required Methods

fn verify<'life0, 'async_trait>(
    &'life0 mut self,
    block: BlockImportParams<B, ()>
) -> Pin<Box<dyn Future<Output = Result<(BlockImportParams<B, ()>, Option<Vec<(CacheKeyId, Vec<u8>)>>), String>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Verify the given data and return the BlockImportParams and an optional new set of validators to import. If not, err with an Error-Message presented to the User in the logs.
