The Quantum Threat to Bitcoin: How a Powerful Computer Can Steal Your Cryptocurrency in Under 10 Minutes

The security of bitcoin relies on a complex mathematical system called elliptic curve cryptography, which creates a one-way map between private and public keys. However, a quantum algorithm known as Shor's algorithm can break this encryption, potentially allowing hackers to steal bitcoin. The recent research by Google has shown that the number of qubits required to run Shor's algorithm has been reduced, making it more feasible to build a quantum computer capable of breaking bitcoin's encryption. The article explains how Shor's algorithm works, and how it can be used to derive a private key from a public key, allowing hackers to steal bitcoin. It also discusses the implications of this vulnerability, including the fact that 6.9 million bitcoin are already exposed and vulnerable to attack. The article concludes by highlighting the need for bitcoin users to be aware of this vulnerability and to take steps to protect their cryptocurrency.
