in response to the hacker attack on Bybit exchange on February 21st and the loss of 1.5 billion USD, Ethereum core developer Tim Beiko stated that, although some industry insiders are calling for the Ethereum network to be restored to its pre-attack state, from a technical perspective, this is almost impossible to achieve.

Beiko emphasized that, unlike the 2016 TheDAO hack incident, this attack did not violate the Ethereum protocol rules, and a rollback would result in widespread and difficult-to-repair chain reactions, potentially causing even greater destructive consequences than the hacker's losses. In addition, a rollback would undo all settled on-chain transactions, without being able to reverse off-chain transactions.

Other industry insiders also expressed similar views. Ethereum educator Anthony Sassano pointed out that the complexity of the current Ethereum ecosystem makes simple rollback of infrastructure unfeasible. Yuga Labs blockchain vice president further warned that the cost of a rollback could far exceed 1.5 billion USD.

In previous news, when asked if he supported rolling back Ethereum to the state before the hack, Bybit CEO Ben Zhou said: "This is not something one person can decide. Based on the spirit of blockchain, maybe it should be decided through a community vote, but I'm not sure."
