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.
