AI Could Damage Crypto in 2 Years, Warns Ethereum's Vitalik Buterin

Vitalik Buterin warned that AI-driven mathematical progress could reach lattice-based cryptography within about two years, and he also said ECDSA may fail sooner than many expect. He paired that warning with a caution not to rush funds into new wallets today, while arguing the industry should make encryption resistant to both quantum computing and AI.

What this rests on

Claim by claim, with its source
✓
Vitalik Buterin said AI-related math advances could weaken lattice-based cryptography within roughly two years.
✓
He also said those same advances could break ECDSA, the signature system used by Bitcoin and Ethereum wallets, sooner than expected.
✓
He said the crypto industry needs encryption that is resistant to both quantum computing and AI.
✓
He wrote that many plans assume elliptic curves fail while hashes and lattices remain secure, and he said lattice keys may need to be about 10 times larger for long-term safety.

What it means

Who it affects, what changes and what is still unconfirmed

Each sentence links inside to the piece that supports it.

Users and wallet holders are the people most likely to notice this first, because Buterin specifically told them not to rush funds today even after raising the possibility of weaker cryptography. The immediate effect is a warning to keep track of wallet and signature assumptions rather than a call to move assets right away.

In practice, the discussion shifts the focus from only quantum-resistance to protection against both quantum and AI-related threats. It also leaves the current setup in place for now, since Buterin said people should not rush to move funds today even while he described a possible need for larger lattice keys.

What remains unknown is whether AI advances will reach lattice cryptography on the timetable he described and whether ECDSA will fail sooner than expected. The open question would be settled by clearer technical progress or by concrete changes in wallet and encryption standards, but those are not described here.
