Ethereum Foundation researcher Justin Drake called on Oct. 7 for the blockchain industry to “calmly begin planning” for “bunker mode,” a controlled shift of holdings to new addresses whose public keys stay hidden behind a hash. He tied the call to OpenAI’s release of 722 mathematical results the day before, writing that it is “reasonable to brace for the possibility that ECDSA breaks before qday, in the worst case in months not years.”
ECDSA is the signature scheme most Bitcoin and Ethereum accounts use. Drake did not claim a break has occurred. He stressed “Don’t rush,” and suggested that large holders consider shifting most of their holdings to addresses that have not yet signed a transaction.

Critics Push Back
Yehuda Lindell, who leads cryptography at Coinbase, called the post “a really bad take” and said there is “no evidence whatsoever pointing to a break of decades old hardness assumptions like elliptic curve cryptography.”
Ledger CTO Charles Guillemet wrote that assuming ECDSA could fall to a classical attack within months as the working scenario “still looks like FUD.” He called avoiding address reuse “reasonable for large holders,” but said a mass migration could create “operational mistakes that lose funds with higher probability than the scenario being mitigated.”
Dankrad Feist argued that if exposed public keys become exploitable and white-hat hackers do not secure everyone’s assets first, “your coins are going to zero,” and bunker mode “is not going to help you.” Helius’s Mert Mumtaz wrote in a post “absolutely do not take justin’s advice btw” and called Drake’s post “an unnecessarily performative post” in the same message.
Dragonfly’s Haseeb Qureshi backed the warning, calling it “a very sober call,” saying the risk is conventional mathematics overturning “unproven cryptographic hardness assumptions.”
Buterin Counsels Caution
Vitalik Buterin wrote in a post that he does not recommend anyone “scramble to move their funds to new wallets today,” though the risks from AI-accelerated math should be taken seriously. He added that ECDSA “might fall even faster than expected,” and that keeping funds in addresses that have not made a transaction “is a good idea” if it is easy. He cautioned: “I personally have lost more money in botched migrations than I have lost in all hacks combined.” He named lattice-based schemes such as ML-DSA as a core new area of risk.
Jacob Creech argued Solana users do not need bunker mode because its keys derive from a hashed seed that is never exposed onchain.
Drake wrote that the Ethereum roadmap’s timelines “must now be revisited and accelerated” in light of what he called mathematical superintelligence.
