Omid Malekan and Lorenzo Valente debate blockchain rollbacks after $6B Binance hack

The largest recorded crypto heist has revived an old argument about whether blockchains should ever get an undo button Somebody drained approximately $6.3 billion from Binance’s hot wallets on October 29, 2026. It is the largest recorded crypto heist, and the money moved across several blockchains at once. Now two well-known voices are fighting about the response. Lorenzo Valente wants major chains to have an emergency undo button for a few years, and Omid Malekan thinks that idea would break the very thing that makes blockchains worth using.
