The latter one. An application-level ack. You only accept a transaction when you have „acked” to your peer that you have the full data payload, and after it acks your ack so that you know your peer won't re-send the same thing over again.

Sounds complicated, but at least your peers can both be aware of each others' intentions.

I don't see much difference between the two, except that on an unstable link, you keep trying harder.
