Say we have txA and txB, and txB contains an input that redeems an output from txA.

In order for a block containing both txA and txB to be valid, is it necessary that txB be after txA in the list of transactions for that block?

  • While I agree that the question is the same, the answer to the other question is simply a long-winded "yes", without any references or sources. How can I mark an answer as correct if I can't judge whether it's correct or not? – runeks Aug 28 '15 at 12:17
