Updated: Jan 02 2026- Quantum Computing Advances: By the end of 2025, the synergy between quantum computing and AI has significantly improved hardware stability and error correction capabilities; however, breaking Bitcoin's encryption is still projected to require 20 to 40 years.
- Bitcoin Security Analysis: Bitcoin's reliance on elliptic curve cryptography is nearly unbreakable by classical computers, but quantum computers could solve this in a short time, particularly targeting high-value early wallets.
- Technical Challenges and Opportunities: Although the quantum threat is viewed as an engineering challenge rather than a physics problem, the most powerful quantum computers have yet to reach the 2,330 logical qubits needed to crack Bitcoin, making it unlikely to achieve before 2035.
- Future Outlook: As quantum computing technology progresses, post-quantum cryptographic methods have been proposed, but Bitcoin developers are cautious about protocol changes, which may lead to cultural resistance as the
