Perhaps we should consider a mechanism to reverse a transaction through a vote or consensus. Haven't fully thought out how this could work but it is something to consider.
Something could be designed to allow miners to reverse a specific transaction (and all subequest tx's) through majority consensus in extreme situations such as this.
Mistakes and thefts happen. Fiat banks have the ability to correct mistakes and reverse transactions unless the funds are withdrawn for cash.
I dunno...just thinking out loud.
This is the Best i heard for that moment!
This is completely contrary to the whole point of crypto. Might as well also suggest a central authority to determine which transactions are legit and which ones need to be reversed.
