AI Threatens Bitcoin Signatures: Is ECDSA Doomed?

An Ethereum Foundation researcher, Justin Drake, has cautioned the blockchain industry to prepare for a potential "bunker mode" scenario. He posits that artificial intelligence could achieve mathematical breakthroughs capable of cracking the ECDSA signature scheme used by Bitcoin, possibly within months, predating quantum computing threats. This concern was amplified following OpenAI's recent release of new mathematical findings.

Drake advised large crypto holders to move funds to new addresses and avoid reusing them to obscure public keys. However, this perspective has met with significant pushback. Critics argue there's no concrete evidence of ECDSA's vulnerability to current AI advancements and that the post-AI cryptography is a hypothetical fear. Some also noted that address non-reuse is standard Bitcoin practice.

Experts like Yehuda Lindell, head of cryptography at Coinbase, have labeled Drake's claims as "fear-mongering," stating there is no evidence that AI can break widely used public-key cryptography. Matthew Green, a cryptography professor, offered a more nuanced view, acknowledging AI's growing mathematical prowess but remaining uncertain about immediate cryptographic threats. The debate highlights ongoing discussions about the future security of digital signatures in the face of rapidly advancing technology.
