Quantum Computing
Billionaire investor Ray Dalio told CNBC that future quantum computing advances could break Bitcoin by undermining its cryptographic foundations. His comments have renewed debate over timelines and the need for quantum-resistant upgrades.
Ledger CTO Charles Guillemet says quantum computers are unlikely to break Bitcoin’s current security in the near term, though vigilance and migration strategies remain necessary.
Bitcoin analyst Willy Woo published a 'Quantum Safe' guide urging holders to migrate to SegWit wallets to reduce exposure to potential quantum computing attacks. The guide explains practical migration steps and highlights why SegWit is a simple, effective near-term defense for BTC holders.
Anatoly Yakovenko, co-founder of Solana, warns at All-In Summit 2025 that Bitcoin's current cryptography may be vulnerable to quantum computers by 2030, urging a hard fork to quantum-resistant signatures. However, experts like Adam Back and Peter Todd remain skeptical about the immediacy of this risk.
