Vitalik Buterin warned that quantum computers could break crypto security as early as 2028

Ethereum creator Vitalik Buterin told developers in Buenos Aires on Tuesday that quantum computers will have the ability to break the cryptography holding Bitcoin and others as early as 2028. Vitalik said “elliptic curves are going to die,” pointing straight at the math that secures wallets, signatures, and every transaction on today’s major blockchains. The concerns grew louder after Google announced a quantum breakthrough last month, following Microsoft’s move in February when it revealed a quantum‑enabling chip. Those jumps pushed quantum danger right into the center of the crypto conversation. The fear is that if hardware keeps moving at this speed, the encryption that protects every on‑chain wallet and every old signature could be exposed within a few years. Researchers warn crypto could break before 2028 Quantum researcher Scott Aaronson said in a blog post that the “staggering rate of hardware progress” makes it a “live possibility” that a fault‑tolerant...
