Ethereum core developer issues an article explaining why it cannot "rollback" the Ethereum blockchain

PANews reported on February 23 that after Bybit was hacked, some people asked why Ethereum cannot "roll back" the blockchain to reverse the hacker attack. In this regard, Ethereum core developer timbeiko.eth posted an explanation. It said that although Bitcoin was able to "roll back" its blockchain 15 years ago, today, the interconnected nature of Ethereum and the settlement of on-chain off-chain economic transactions have made this problem tricky today.
