Ethereum Foundation researcher Justin Drake has called on the blockchain industry to begin planning for “bunker mode,” a controlled mass migration of funds to fresh addresses whose public keys remain hidden behind a hash. He warns that ECDSA, the signature scheme used by Bitcoin and Ethereum, could be broken before Q-Day, potentially within months rather than years, citing rapid advances in AI-driven mathematics. Drake emphasized that holders should not rush or panic, and urged major platforms like Binance, Bitbank, Robinhood, Bitfinex, and Tether to harden their cold storage. The Ethereum Foundation has already formed a dedicated post-quantum team this year, and Drake said he will push for maximum acceleration of the transition to hash-based cryptography.
