Ethereum: Drake Warns About AI, Buterin Calls for Caution

No ECDSA hacking has been demonstrated to date, but the prospect of AI-assisted mathematical breakthroughs is worrying figures in the Ethereum community. Justin Drake urges the ecosystem to adopt a defensive stance, while Vitalik Buterin supports the direction but warns of the dangers of hasty migrations.

No ECDSA bypass observed, and caution on migrations

To date, no successful attack against the ECDSA signature scheme used by Ethereum wallets has been reported. Vitalik Buterin warns against rushing fund migrations, emphasizing that he has personally lost more during failed migration attempts than through hacks. For the future, he recommends prioritizing architectures that rely as much as possible on hash functions alone. He also believes that cryptographic schemes based on networks, often considered resistant to quantum attacks, could also be vulnerable to advancements in artificial intelligence.

Proposed measures: prioritize never-signed addresses

Justin Drake recommends transferring funds to addresses that have never been used to sign a transaction. Once a transaction is validated by a signature, the public key of the address becomes accessible, theoretically allowing an attacker to deduce the private key to access the funds. As long as only the hash of the public key is visible, it is impossible to retrieve the key from this hash, ensuring the security of the funds. Vitalik Buterin supports the idea of prioritizing never-signed addresses while calling for caution in implementing this measure.

A rapid disruption scenario discussed by researchers

AI-assisted mathematical advancements are sparking a debate among Ethereum researchers about how quickly wallet security could be compromised. Justin Drake warns that, in the worst-case scenario, the signature system could be endangered within a few months and calls on the blockchain industry to prepare for a "bunker mode" in the face of this risk, even if it remains hypothetical.
