A recent study reveals that quantum computers could potentially steal Bitcoin by deriving private keys from public keys in about nine minutes using Shor's algorithm. This poses a significant risk to the estimated 6.9 million Bitcoin already exposed on the blockchain, highlighting the urgent need for enhanced security measures.
- 01Quantum computers could derive Bitcoin private keys from public keys in about nine minutes using Shor's algorithm.
- 02Bitcoin's security relies on elliptic curve cryptography, which is vulnerable to quantum attacks.
- 03Google's recent paper reduced the required qubit count for such attacks to fewer than 500,000.
- 04Approximately 6.9 million Bitcoin are at risk due to already exposed public keys.
- 05The threat emphasizes the need for urgent advancements in Bitcoin security protocols.

Quantum computers pose a significant threat to Bitcoin security, with the potential to derive private keys from public keys in about nine minutes using Shor's algorithm. Bitcoin's encryption relies on elliptic curve cryptography, which is currently secure against classical computers but vulnerable to quantum attacks. A recent paper by Google’s Quantum AI division revealed that the number of qubits needed for such an attack has been reduced to fewer than 500,000, significantly lowering the barrier for potential attackers. The study highlights that approximately 6.9 million Bitcoin are already at risk, as their public keys have been permanently exposed on the blockchain. This situation underscores the urgent need for enhanced security measures in the cryptocurrency space to protect against future quantum threats.
