Another subset of valid transactions are Denial of Service (DOS) transactions, which for one reason or another will cause a node to have a bad time. For example a DOS transasction might crash the node, or cause it to take a very long time to validate. We know about a number of DOS transactions, but presumably there are some DOS transactions which we don't yet know about. So we can add to our diagram two circles, one for all DOS transactions, and within that a smaller circle for the known DOS transactions.
