/// 1. This method will fail on any error without removing invalid transaction.
/// 2. It means that the transaction will be stuck there forever and we will never be able to make any progress.
///
/// It might be more sensible to `drain()` transactions from the queue instead and process all of them,
/// possibly printing some errors in case of failures.
/// The 3 methods `ready_transaction,get_descriptor,remove` are always used in conjuction so most likely
/// can be replaced with a single `drain()` method instead.
/// Thanks to this we also don't really need to lock the entire verification for the time of execution.
