So you agree ring signature entanglement from the coinbase transactions of the attackers fork could in theory occur??
How to unwind those?
This is a good question.
I'd like to think about it a bit, but I am still cleaning up the NEFT that spurted out of my face a while back.
After that, I'm going to feed the alpacas and see if anything comes to me.
It is a really good question. Just too many distractions at the moment.
