Ethereum Researchers Warn AI Could Crack Crypto Before Quantum Computers

The Urgent Need for Bunker Mode

Ethereum researchers Justin Drake and Vitalik Buterin have warned of the potential for AI to threaten cryptocurrency security before quantum computers do. Drake, an Ethereum researcher, has called for users to prepare for a 'bunker mode' approach, where funds are moved to fresh wallets to avoid exposure to public keys. Buterin, Ethereum co-founder, supports this approach, noting risks to both elliptic curve digital signature algorithm (ECDSA) and lattice-based cryptography. He suggests a gradual migration to fresh addresses as a precautionary measure.

The Risks of AI to Cryptography

Drake's concerns stem from recent advancements in AI, which have revealed how quickly the technology is advancing in mathematics. OpenAI, for instance, has released hundreds of new mathematical findings across various fields. Drake highlights the vulnerability of elliptic curves, which carry rich structure and room for fancy tricks like Schoof and Frobenius. He also points out the potential for AI-driven mathematical advances to weaken lattice-based cryptography, which is believed to resist quantum attacks.

The Ethereum Roadmap and Hash-Only Direction

Buterin flags risks to quantum-resistant cryptography and suggests that Ethereum's lean roadmap has been going in the 'hash-only' direction. He notes that most people have been in the mode of thinking 'elliptic curves broken, hashes safe, lattices safe,' but there is a good chance that the concrete security of lattices will take serious hits from the next two years of AI math.

The Importance of Controlled Migration

Both researchers suggest that holders could reduce their exposure by keeping funds in addresses whose public keys have not been revealed. Drake recommends a gradual and carefully managed migration to fresh addresses, with large and sophisticated crypto holders being the first to move their funds. Buterin supports the precaution if it is straightforward to carry out, but warns of risks associated with moving funds, such as the loss of money in botched migrations.

Conclusion

The warning from Ethereum researchers highlights the growing concern about AI's potential to undermine cryptocurrency security. The adoption of a 'bunker mode' approach, where funds are moved to fresh wallets, is seen as a prudent measure to mitigate risks. The shift towards a 'hash-only' direction in Ethereum's roadmap is also seen as a response to these concerns.
