Experts Warn Quantum Computing Threatens Bitcoin Security By 2035

Quantum computing poses a significant and evolving threat to Bitcoin's cryptographic security, particularly targeting elliptic curve cryptography that underpins the blockchain. Tools like Project11's address vulnerability checker highlight risks from exposed public keys, especially those linked to older or reused address formats, urging users to migrate to quantum-resistant addresses. Experts, including Charles Edwards, warn of a critical 12-month window to implement post-quantum cryptographic solutions once selected, with potential market volatility and shifts in trading strategies anticipated. Research from Google's Craig Gidney suggests that credible quantum threats to Bitcoin could emerge by 2030 to 2035, accelerating the urgency for proactive security measures. Meanwhile, voices like Adam Back caution that while immediate risk may be distant, preparedness and gradual adoption of post-quantum cryptography are essential to safeguarding digital trust. Overall, the transition to post-quantum cryptography is framed as a necessary evolution, requiring measured steps by businesses, governments, and the crypto community to mitigate the looming quantum threat without causing disruption.
