Ledger CTO Charles Guillemet has rebuffed fears that AI could break Bitcoin’s cryptography in the coming months.

He said there is no sign of an imminent breakthrough that could break the Elliptic Curve Digital Signature Algorithm (ECDSA), the cryptographic system used to secure Bitcoin transactions.

Is Fear Overblown?

Guillemet went on to explain that if asymmetric cryptography were broken, “Bitcoin will be the least of our problems.” Internet security, banking systems, secure communications, and critical infrastructure could all face serious problems. While he admitted that recent mathematical advances are impressive, the exec said they do not represent a practical breakthrough against ECDSA.

“And if your logic is that nothing can be trusted until it’s proven unbreakable, congratulations. By that standard, nothing is safe, including hashes.”

Guillemet urged people to follow cryptography research and take potential risks seriously. But he warned against treating theoretical progress as a sign that a cryptographic crisis is just months away.

The comments come after Ethereum Foundation researcher Justin Drake made a startling warning about the potential risks AI poses to cryptography. Drake urged the industry to calmly prepare for “bunker mode” and said crypto holders should consider moving funds to fresh addresses whose public keys have never been exposed. He believes ECDSA could potentially be broken within months rather than years.

Drake cited recent mathematical breakthroughs and OpenAI’s latest release as reasons to take the risk seriously. However, he added that holders should not rush into moving their assets, while warning that a hurried migration could do more harm than good. The researcher called on major crypto platforms to strengthen their cold storage security and urged the industry to accelerate its shift towards hash-based cryptography. He said the industry should prepare without panicking.

Theoretical Threats Can Wait

While Vitalik Buterin also believes that the rapid progress in AI-assisted mathematics could pose new risks to existing cryptographic systems, he warned against rushing into wallet migrations. The Ethereum co-founder asserted that moving funds without proper planning could create fresh risks for users.

Meanwhile, prominent Bitcoin developer and Casa co-founder Jameson Lopp said that worrying about cryptographic breaks is getting ahead of ourselves. He added that the industry has “much more pressing actual issues to deal with.”
