Tim Beiko's full article: Why can't Ethereum roll back after the Bybit event The high degree of interconnectivity means that any abnormal state changes, even if socially acceptable, will have almost unmanageable chain reactions. Completely 'rolling back', even if the recent chain history is partially invalid, will make things worse. Any settled transaction, many of which have an impact outside of Ethereum (such as exchange sales, RWA redemptions, etc.), will be revoked, but its off chain portion cannot be revoked.
