OpenAI Math Results Prompt Ethereum’s ‘Bunker Mode’ Warning

Ethereum researcher Justin Drake urged crypto holders to prepare for what he called “bunker mode” after OpenAI released new mathematical results generated by an internal frontier model.

Drake made the recommendation on Oct. 7, one day after OpenAI published results from tests involving thousands of mathematical problems. The company included computer-checkable formal proofs written in Lean for many of the results.

OpenAI’s announcement did not demonstrate an attack on ECDSA or RSA. Drake’s warning describes a possible future breakthrough, not a current ability to recover private keys or take control of crypto wallets. In a worst-case scenario, he estimated that AI could help break the Elliptic Curve Digital Signature Algorithm, or ECDSA, “in months, not years.”

Bitcoin and Ethereum use elliptic-curve cryptography to prove ownership and authorize transactions. Standard Ethereum accounts use ECDSA with the secp256k1 curve. After an account sends a transaction, its public key can be reconstructed from information recorded on the blockchain. Anyone who could efficiently derive the related private key could then control the account’s assets.

Ethereum addresses that have never signed a transaction provide an additional layer of protection. In those cases, the blockchain shows an address derived from a public key rather than the public key itself.

Drake urged large holders to move most of their assets to unused addresses and avoid unnecessary outgoing transactions. After using such an address to send funds, he recommended transferring any remaining balance to another unused address.

The protection differs among wallet types. Bitcoin Taproot outputs expose a public key from the outset and use Schnorr signatures rather than ECDSA. Both systems use the secp256k1 elliptic curve.

Drake specifically urged Binance, Bitbank, Robinhood, Bitfinex and Tether to review their cold-storage practices. He also recommended that oracle operators and layer-2 security councils rotate ECDSA keys after signing messages or combine current signatures with hash-based systems such as SPHINCS.

Those measures would provide interim protection rather than replace existing cryptographic systems. Drake favors hash-based cryptography for long-term use because it has less algebraic structure than elliptic-curve, lattice and isogeny-based systems.

Ethereum’s post-quantum research program includes hash-based signatures for validators and designs that would let individual accounts use different signature systems. The network’s current target for core post-quantum infrastructure is about 2029, although the schedule can change.

The industry has generally treated the risk of breaking elliptic-curve cryptography as a future quantum-computing problem. Drake raised the possibility that AI could help discover a classical method that reduces the difficulty of recovering private keys. He referred to a potential classical counterpart to Shor’s algorithm, which would threaten both elliptic-curve cryptography and RSA. No such method is known.

Europol has warned that quantum computing could eventually weaken the cryptography protecting cryptocurrency wallets. The agency has urged the industry to begin preparing because replacing cryptographic systems and coordinating upgrades could take years.

Drake also cautioned that rushed transfers could create operational risks. Ethereum’s second post-quantum research retreat is scheduled for Oct. 9 to Oct. 12. Drake plans to discuss defensive preparations with institutional participants in London next month.
