+
+Blocks that include invalid transactions have an additional field, 
+`transactionSequence`. This field is an array of transaction information. 
+Each entry in the array has two fields:
+
+- `valid`, true for valid transactions (which also appear in the `transactions` field),
+  false for invalid ones.
+- `rawBytes`, the rlp-encoded raw bytes of the transaction
+
+Entries for invalid transactions have this additional field:
+
+- `exception`, for invalid transactions, the name of the exception they create.
