Ethereum Foundation researcher Justin Drake wants the blockchain industry to start preparing for a world in which the signature scheme securing Bitcoin and Ethereum fails earlier than anyone expected, and he says the cause may not be quantum computers at all. In a post on X on Wednesday, Drake urged holders to plan a gradual shift of assets into addresses that have never signed a transaction, leaving their public keys concealed, Decrypt reported.
Drake told his audience not to panic or move quickly. His recommendation, which he labelled “bunker mode,” is that funds migrate in a controlled way to fresh addresses, and that the migration requires no new cryptography and no new wallets.

Key facts
- Drake said ECDSA, the signature scheme behind Bitcoin and Ethereum, could break in the worst case “in months not years.”
- He defined “break” as recovering a private key in roughly a week using hardware such as a large GPU cluster.
- He cited 722 results OpenAI published on Tuesday as evidence that long-held mathematical assumptions are weakening.
- He said wallets holding less than 50 BTC have partial cover from “Satoshi’s shield,” roughly 20,000 exposed addresses tied to Bitcoin’s creator, each holding 50 BTC.
- Drake said he will push to accelerate Ethereum’s shift to hash-based cryptography.
Why an exposed public key is the weak point
The risk Drake describes sits in how wallets prove ownership. When a wallet signs a transaction, its public key is written on-chain. If an attacker can derive the private key from that public key, the funds in the wallet are open to being drained. Addresses that have never spent retain the protection of a hash, which does not expose the key the same way.
Drake argued that elliptic curves, the mathematics ECDSA relies on, are especially exposed to superintelligence because their structure offers attackers more angles than hash functions, which are built to resist them. That distinction is why he wants Ethereum’s roadmap to move faster toward hash-based cryptography.

The warning is an escalation of a concern Drake has raised for years. In March, after a Google paper argued quantum computers could break crypto’s cryptography sooner than expected, he put the odds of Q-Day arriving by 2032 at 10% or more. The Ethereum Foundation formed a dedicated post-quantum team earlier this year, and co-founder Vitalik Buterin has outlined plans to move the network toward quantum-resistant cryptography.
Drake also directed part of his message at institutions, naming Binance, Bitbank, Robinhood, Bitfinex and Tether and recommending they harden their cold storage.
Why it matters
ECDSA underpins the two largest blockchains and the wallets of millions of users, so a credible path to breaking it is a systemic concern rather than a single-product bug. Drake’s framing changes the timescale of the debate: instead of a distant quantum milestone, he is describing a nearer-term math problem in which AI progress, not hardware, drives the risk. For the average holder, the practical implication is procedural. Moving coins to a never-used address is cheap and available today, and it removes the on-chain exposure that makes a wallet vulnerable. The larger question is whether exchanges and custodians with cold storage will act on the same timeline.
What to watch
Two things will show whether Drake’s call gains traction: whether Ethereum’s developers accelerate the move to hash-based cryptography, and whether the exchanges and stablecoin issuers he named announce hardened cold-storage practices in response. The 722 OpenAI results he pointed to are also worth tracking, since further AI-driven advances in mathematics would sharpen his argument.
This is not financial advice, and crypto markets remain volatile and uncertain.
