Ethereum Core Developer: Rollback Nearly Impossible to Achieve, Could Lead to Hard-to-Repair Chain Reaction

February 23rd: Regarding the hacking incident that took place on February 21st and led to the breach of the Bybit exchange with a loss of $1.5 billion, Ethereum core developer Tim Beiko stated that although some in the crypto industry are advocating for the restoration of the Ethereum network to its pre-attack state, from a technical standpoint, this is nearly impossible to achieve. Beiko emphasized that unlike the 2016 TheDAO hack, this attack did not violate the Ethereum protocol rules. A rollback would give rise to widespread and difficult-to-fix cascading effects, potentially resulting in even more destructive consequences than the hacker's losses. Additionally, a rollback would nullify all settled on-chain transactions and could not reverse off-chain transactions. Other industry figures have expressed similar viewpoints. Ethereum educator Anthony Sassano pointed out that the current complexity of the Ethereum ecosystem makes a simple rollback of infrastructure unfeasible. The vice president of blockchain at Yuga Labs also warned that the cost of a rollback could far exceed $1.5 billion. In earlier news, when asked whether he supported rolling back Ethereum to a pre-hack state, Bybit CEO Ben Zhou said: "This is not something that one person can decide. Based on the spirit of blockchain, perhaps it should be determined through a community vote, but I'm not sure." (Cointelegraph)
