i am still worried about the descendant size limit in practice though. if one of my customers is some giant exchange doing a massive sweep that's close to 100 KB in size, and they 0conf spend an output from my tx, that will compromise my ability to cpfp the tx, correct?
well, i guess 100Kb is a _lot_
So fix it.
I agree that if a single "ordinarly created" txn can will defeat CPFP that shouldn't be possible.
The size isn't even an important aspect of the DOS protection, it could be handled entirely differently.
gmaxwell, I'm willing to put in some time to fix it, but as most relay things It's Complicated and I'd need some guidance
aside from one-off things like bumping the size aspect so that a single standard tx cannot do this
