Vitalik Buterin Sees AI Threat To Cryptography, Rejects Rushed Wallet Moves

Ethereum (ETH) co-founder Vitalik Buterin says AI-assisted mathematics could weaken widely used cryptography sooner than expected, but users should not rush to move funds.

Key Points:

Buterin says AI may discover mathematical shortcuts affecting ECDSA, lattice systems and other structured cryptography.

He opposes immediate wallet migrations, citing losses from poorly executed moves.

Coinbase cryptography chief Yehuda Lindell says there is no evidence elliptic-curve assumptions are close to breaking.

Buterin Wallet Warning

Buterin made the comments after Ethereum researcher Justin Drake urged the industry to prepare for “bunker mode,” CryptoPotato reported Oct. 8. Drake argued that large holders should consider new addresses whose public keys remain hidden behind hashes because ECDSA could theoretically fail within months rather than years.

Buterin rejected the urgency. He said users should not “scramble to move their funds to new wallets today,” though he wants the ecosystem to reduce dependence on cryptography vulnerable to quantum computers and possible AI-discovered shortcuts.

His concern also includes lattice-based systems used in ML-DSA and fully homomorphic encryption. Ethereum’s lean roadmap favors hash-based methods such as WOTS and SPHINCS- when suitable, avoiding lattices and related commitments in zero-knowledge proofs where alternatives exist.

Yehuda Lindell Pushback

Lindell, head of cryptography at Coinbase, disputed Drake’s scenario, saying there is “no evidence whatsoever” that long-standing elliptic-curve assumptions are nearing failure. He also said recent AI math advances do not show ECDSA is about to break.

If elliptic-curve cryptography were broken, effects would reach far beyond crypto wallets. Digital certificates, banking software, secure websites, VPNs and other public-key systems could also be exposed, making the issue broader than blockchain security.

Buterin took a middle position: prepare for structural risk without forcing users into abrupt migrations.

For multisig wallets, he corrected an earlier suggestion and recommended that each signer change keys after every operation, while warning that failed migrations had cost him more than all hacks combined.

The debate fits Ethereum’s longer push toward cryptographic designs that can better withstand future breakthroughs. Buterin has increasingly emphasized hash-based tools in the lean roadmap, while noting that public-key encryption remains necessary for communications and finance and may eventually require larger keys.
