Vitalik Warns: Quantum Computers Could Threaten Ethereum and Bitcoin by 2028
At Devconnect, Vitalik Buterin delivered a warning that sounds straight out of science fiction - but it’s real. He explained that the quantum computers could break the cryptography securing the Ethereum and Bitcoin as early as 2028.
Currently, both chains are safe because classical computers cannot solve the complex math protecting private keys.
Quantum machines, however, run Shor’s algorithm, which can crack these equations. Research suggests fault-tolerant quantum computers could appear within four years, putting coins in older addresses with exposed public keys at risk.
Bitcoin: Roughly 5 million BTC sit in vulnerable addresses.
Ethereum: Older spent or reused addresses also face exposure.
Vitalik emphasizes the need for quantum-safe tools like STARKs.
Ethereum has a clear plan to adopt them early, while Bitcoin’s slower governance may cause delays.
This isn’t hype - it’s a reality check. The Blockchain security is not static; it evolves alongside technology. If quantum power arrives before networks update, the damage could be substantial.
The takeaway: Stay informed, support protocols preparing for quantum threats, and recognize that crypto security is ongoing work, not a one-time fix.
Quantum change is coming. Chains that adapt will survive. Those that wait may not.
