The recent hack of Binance which resulted into the loss of 7,000 Bitcoin valued approximately around $40 Million shocked and dismayed many people in the world of cryptocurrency all because we are assuming too much that as the leader Binance is employing the best security technology they can find but alas hackers are always one step ahead of the game.
Now, there is this talk about the "rollback" which can possibly reverse the 7,000 BTC transfer. This is considered to be conroversial since we don't know the possible consequences and there is the need to get the support of at least 51% of miners.
I think that it is really about time that the industry find an acceptable solution in case of a major hack as it can be frustrating to just watch the hacked Bitcoin moving from one address to another while you are helpless about it.
