Warning ⚠️ ⛔️ #BTC
🔹 Quantum computers could soon crack Bitcoin's encryption with fewer than 1 million qubits, posing a significant security threat.
Yes, that statement reflects a real and growing concern in cybersecurity. Here’s a clearer breakdown:
Quantum Threat to Bitcoin Encryption:
• Bitcoin uses ECDSA (Elliptic Curve Digital Signature Algorithm) for securing transactions.
• A sufficiently powerful quantum computer running Shor’s algorithm could break ECDSA by deriving private keys from public ones.
• Estimates vary, but researchers suggest fewer than 1 million stable, error-corrected qubits could be enough to do this in a practical time frame.
• Today’s quantum computers (like those from IBM or Google) are still in the hundreds of qubits range, and not error-corrected, so Bitcoin remains safe for now.
• However, progress in quantum error correction and scalability could make this feasible within a decade or two.
Mitigation:
• Developers are working on post-quantum cryptography and quantum-resistant protocols to protect Bitcoin and other blockchains before quantum threats become real.
