Vitalik Buterin Warns AI Could Crack Crypto's Core Security Within Two Years
Oct 8, 2026
Vitalik Buterin says AI-driven math breakthroughs could challenge crypto's core cryptography within two years, putting pressure on standards like ECDSA sooner than expected.
A tighter timeline than expected
Vitalik Buterin just dropped a warning that's worth paying attention to. The Ethereum co-founder says artificial intelligence could speed up mathematical research enough to seriously challenge the cryptography that secures crypto today — and he's putting the window at just two years, not decades.
The worry isn't that AI will "hack" blockchains directly. It's that AI-assisted math could find shortcuts against lattice-based schemes like ML-DSA and homomorphic encryption (FHE), and eventually put pressure on older standards like ECDSA, which still protects most wallets and signatures in use today.
Why this matters now
This isn't the first time quantum computing has been flagged as a long-term risk for crypto, but Buterin's comment reframes the threat as something that could arrive on AI's timeline instead of quantum hardware's. For an industry that still runs largely on decades-old cryptographic assumptions, that's a much shorter runway to upgrade.
Expect more talk about post-quantum migration plans across major protocols in the coming months.
