Justin Drake Calls for Crypto “Bunker Mode” Amid Quantum Concerns

Ethereum Foundation researcher Justin Drake urged crypto holders to prepare for a possible break in elliptic-curve cryptography, recommending that large holders consider moving funds to fresh addresses whose public keys remain hidden behind hashes. He called the preparation “bunker mode,” but stressed that existing cryptography has not been broken and warned against rushed transfers.

Why it matters

Bitcoin and Ethereum use the Elliptic Curve Digital Signature Algorithm (ECDSA) to verify transactions. A sufficiently capable quantum computer could potentially derive a private key from an exposed public key. Drake warned that a break could arrive in “months not years,” but described that as a risk scenario, not a confirmed timeline. He also raised the possibility that advances in AI-assisted mathematics could help produce a non-quantum attack on elliptic-curve cryptography.

Drake said public keys can become visible after an address signs a transaction, so he recommended moving remaining funds from such addresses as well. He called on Binance, Bitbank, Robinhood, Bitfinex and Tether to consider stronger protection for cold storage. Project Eleven’s Bitcoin Risq List tracks more than 14 million Bitcoin addresses with exposed public keys. Drake cited roughly 20,000 exposed addresses associated with Satoshi Nakamoto, each holding 50 BTC, as a potential priority for attackers; he said wallets below 50 BTC have some protection from what he calls “Satoshi’s shield.”

Market impact

Ethereum’s current guidance says quantum computers cannot break its cryptography today and users do not need to act. Drake’s recommendation is therefore a call for preparation, not an instruction for an immediate mass migration. Rushed transfers could create additional risks.

Drake pointed to Ethereum’s draft roadmap, which moves toward hash-based cryptography and formal verification. He said a safe return from “bunker mode” would require what he calls “post-AI cryptography,” favoring hash-based security over systems built on mathematical structures such as elliptic curves.
