Agreed on not using "unaborted", per previous discussion.

Yeah, I don't understand why we need this "transaction block" term at
all. It adds nothing. We could just use the term "transaction", and
little meaning would be lost. When necessary, we could just say
"explicit transaction" or something to that effect. In this particular
case, we could modify your proposed wording,

by removing the word "block":

and perhaps add "explicit", but I don't think it's necessary:

(I also changed "An" to "Any" because it seems more natural, but I
suppose it's a stylistic choice.)
