Ethereum Researcher Urges Crypto Bunker Mode as AI Could Break Wallet Keys in Months

An Ethereum Foundation researcher has told the crypto industry to start preparing for what he calls bunker mode, a slow, controlled move of funds into fresh wallets, warning that artificial intelligence could break the mathematics protecting bitcoin and ether wallets in the worst case within months, not years.

"Today I call upon the blockchain industry to calmly start planning for 'bunker mode,'" Justin Drake wrote in a post on X on October 7, which CoinDesk reported had been viewed almost 4 million times. Drake is a researcher at the Ethereum Foundation.

The 722-paper trigger

Drake pointed to a batch of 722 mathematical manuscripts OpenAI released on October 6, produced by an unreleased frontier model across roughly 4,000 problems, as evidence that AI is advancing in mathematics far faster than expected, Cointelegraph reported. He noted the company had last month used a team of 10,000 autonomous AI agents working in parallel to solve the Navier-Stokes equation, one of the most famous unsolved problems in mathematics and physics, in 88 hours. "Recent days have been humbling for human mathematical intuition. Long-held, unquestioned hypotheses have fallen," Drake wrote.

His worry is the elliptic curve digital signature algorithm, or ECDSA, the signature scheme that secures bitcoin and ether wallets. A wallet uses a secret number, the private key, to authorize payments, while a related public key lets the network check those approvals. Going from the public key back to the private key is supposed to be impossibly hard, but Drake argued AI could help someone find a shortcut that lets an attacker recover the secret and spend the coins on ordinary hardware, with no need for the quantum computers the industry has spent years preparing for. He defined his worst case as fast private key recovery, for example within one week, on available hardware such as a large GPU cluster, blockchainreporter reported.

Drake argued that elliptic curves could be especially exposed to superintelligence because curves carry rich structure, citing tricks like Schoof's algorithm, the Frobenius endomorphism and pairings, while hash functions are designed to minimize algebraic structure, Cointelegraph reported.

Vitalik says do not scramble

Ethereum co-founder Vitalik Buterin responded on Wednesday that the risk to cryptography from AI-accelerated math should be taken seriously, but he advised holders against rushing to move funds. "I don't recommend anyone scramble to move their funds to new wallets today," Buterin wrote. He noted that botched migrations have cost him more than hacks, according to The Block. Buterin added that AI math could also weaken some quantum-resistant cryptography, naming lattice-based schemes including ML-DSA as an area where security "will take serious hits" over the next two years of AI math, TradingView reported.

Not everyone accepted the urgency. Samson Mow, CEO of bitcoin technology firm Jan3, told followers there was no need to panic "because an Ethereum researcher is saying silly things," CoinDesk reported.

What bunker mode means for holders

Drake's proposal is gradual, not a panic sell. He recommended that large holders and institutions start moving funds to fresh addresses whose public keys have never appeared onchain, since an exposed public key is the prerequisite for any future attack. Millions of bitcoin sit in addresses whose public keys are already visible onchain, CoinDesk has previously reported, and on Ethereum any account that has ever sent a transaction has revealed its key, with stablecoins and tokenized funds issued on the network controlled through the same signature system. Crypto.news noted that Project Eleven tracks those exposed Bitcoin addresses as part of its monitoring. Drake repeatedly warned against panic, saying a poorly managed migration creates its own risks.

No working attack on bitcoin or Ethereum's wallet keys has been demonstrated, and none appeared in the research reviewed by CoinDesk. Ethereum already has a dedicated post-quantum team targeting core quantum-resistant infrastructure around 2029, and the US National Institute of Standards and Technology standardized the hash-based SLH-DSA signature scheme in 2024, crypto.news reported.
