The Quantum Threat to Bitcoin's Encryption*
Quantum computers could break traditional encryption algorithms like **ECDSA** (Elliptic Curve Digital Signature Algorithm), which secures Bitcoin transactions, by using "Shor's algorithm" to derive the private key from the public key in record time. Recent research from Google suggests this threat is closer than expected, as quantum computers may break RSA-2048 encryption with **20 times fewer resources** than previously estimated.
