It isn’t about “attacking” the UTXO in my thinking. It’s about submitting a malicious one, and then ACKing it despite contradicting with the rules of the sidechain.
I’ll try to take some time this week to go back through the links you gave. I still just feel like I get dismissal with most of the concerns and I really want to see and get the process on *exactly what happens* in the case of a malicious miner. Not a statement that they won’t exist. Same thing we did with Ark, just spent the entire episode trying to break down and make a shape of this thing by attacking all of the edge cases.
