Bitcoin’s Security Could Face Quantum Computing Risks Within Years, Expert Suggests

Key Points

1. Bitcoin's reliance on elliptic-curve cryptography (ECC) is vulnerable to quantum computing, which could crack its security within three to five years.

2. The term 'Q-Day' refers to the anticipated moment when quantum computers can break current cryptographic systems, with companies like Google, Microsoft, and IBM advancing quantum technology.

3. Experts suggest migrating to quantum-resistant wallets and developing post-quantum cryptographic solutions to mitigate future risks.

4. Industry leaders like Adam Back advocate for a measured approach to transitioning to quantum-secure systems, emphasizing long-term preparedness.

5. The crypto ecosystem must proactively update security frameworks to address the potential threat of quantum computing breakthroughs.
