THE BLOCK: Ethereum Foundation researcher Justin Drake is urging the crypto industry to begin planning for "bunker mode," recommending a controlled migration of assets to fresh addresses that have never signed a transaction, keeping their public keys hidden behind a hash. Drake said it is now reasonable to prepare for the possibility that AI could enable fast recovery of private keys from ECDSA public keys, potentially within "months not years." "Don't rush," Drake said, warning that a disorderly migration could cause more harm than good.
