Ethereum researcher calls for 'bunker mode' crypto migration, says AI could crack keys before quantum does

An Ethereum Foundation researcher is pressing the industry to start moving coins now against a threat that doesn't exist yet — and to broaden the list of what might eventually cause it.

Justin Drake, who has warned for years that quantum computers could one day break the elliptic-curve cryptography securing blockchain funds, said this week that artificial intelligence might reach that point first. "Today I call upon the blockchain industry to calmly begin planning for 'bunker mode,'" Drake wrote on X, in comments reported by Decrypt on October 14.

The mechanism he proposes is specific. Drake recommends a controlled, mass migration of funds into fresh addresses that have never signed a transaction — addresses whose public keys remain hidden behind a hash. The logic rests on how Bitcoin spending works: a public key is only exposed once an address sends a transaction, and it is the exposed key that a sufficiently powerful attacker could, in theory, reverse to derive the private key. Coins sitting in never-spent addresses keep that key concealed.

Decrypt framed the piece around Coinbase urging the migration to begin immediately, noting such a transition "can take years." The detail available does not spell out Coinbase's formal position, timeline, or any technical basis for Drake's claim that AI, rather than quantum hardware, is the nearer-term danger.

Key facts

• Justin Drake, an Ethereum Foundation researcher, publicly called on the blockchain industry to "calmly begin planning for 'bunker mode'" and to migrate funds to fresh, never-signed addresses — per Decrypt, October 14, 2026.
• Drake argued AI may break cryptographic encryption before quantum computers do — Decrypt.
• The proposed defense relies on keeping public keys hidden behind a hash until a transaction is signed — Decrypt.
• Decrypt's headline attributes to Coinbase a push to start the migration now, warning it "can take years"; specifics of Coinbase's stance were not laid out in the available detail.

The real-world read

This is one secondary report, and the load-bearing claims are forecasts, not events. Drake offers no timeline, no benchmark, and no technical case — at least none that survived into the available text — for the striking assertion that AI will break encryption before quantum does. Treat it as his opinion.

Worth noting who's talking: Drake's day job is researching Ethereum, yet the migration advice applies most directly to Bitcoin's spending model. That's not a conflict, but it is cross-chain commentary, not a Bitcoin-core position. And the Coinbase angle doing the headline's work isn't substantiated in what's available — an exchange that custodies large balances has obvious reasons to favor a slow, orderly migration it would help manage. Nothing here establishes an imminent threat; it establishes that some researchers want contingency planning to start early. Those are different claims.

Opinion, and whose

• Justin Drake (Ethereum Foundation): the industry should begin a precautionary "bunker mode" migration now, and AI may crack keys before quantum computers.
• Coinbase (per Decrypt's framing): the migration should start immediately because it "can take years." The underlying position wasn't detailed.
