DRK is a mixer too and they solve this issue by using signatures which removes the incentive for DRK nodes to steal. We both know that XC can use this same idea to solve the issue too. Funny how you don't mention it though.
You pretend well but your ultimate aim is to make XC look bad, not really to "help".
I have suggested it.
If they were on the same block, xnode would not have lost its coins in case of orphaned block, right? In other words, they both went to wrong fork and once it is detected it could be corrected.
Another question is how to ensure they are on the same block.
Current design require two tx.
Make it to single tx.
