What Is Q-Day? Is it Really a Quantum Threat to Bitcoin
Antara Bhattacharyya
What Is Q-Day?: Q-Day refers to the hypothetical moment when quantum computers become powerful enough to break modern encryption systems used today.
Why Q-Day Matters: Quantum computers could decrypt sensitive blockchain data, exposing private keys, wallets, and traditional online security systems worldwide without consent.
Is Bitcoin at Risk?: Bitcoin’s cryptography relies on algorithms that quantum machines may crack, potentially allowing attackers to steal or manipulate digital assets rapidly.
How Bitcoin Is Defending: Developers are working on quantum-resistant upgrades using post-quantum cryptography and multi-signature security to ensure long-term safety.
Should Investors Panic?: Experts say Q-Day is still years away, giving the crypto world enough time to upgrade and transition securely
