Can Quantum Computers Hack Crypto? Vitalik Buterin Places Odds at 20% by 2030

• Quantum computing could compromise cryptography sooner, threatening digital finance security
• Blockchain systems face risks to soundness, not just data exposure, under quantum pressure
• Post-quantum algorithms and advanced zero-knowledge proofs are vital for future resilience

A stark warning from Ethereum co-founder Vitalik Buterin is forcing a hard conversation about the long-term security of crypto. He puts the odds at 20% that powerful quantum computers could break modern cryptography before 2030, a much shorter timeline than most experts predict. 

His forecast forces the entire industry to confront a tough reality: the digital economy, from banking to crypto, runs on math that may soon be obsolete. 

Why the Quantum Threat Cannot Be Ignored

Modern cryptography protects the very foundation of global finance. Crypto wallets, exchanges, and smart contracts all rely on encryption that today’s computers can’t crack. 

The problem is t…
