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

The first part of this series delved into the principles of quantum computing, explaining how it differs from classical computing and the unique properties that make it powerful. However, understanding the mechanics of quantum computing is only half the story; the other half is how it can be used to compromise the security of bitcoin. To grasp this, we need to understand what bitcoin's security is based on and where its vulnerability lies. This article starts with an overview of bitcoin's encryption method, known as elliptic curve cryptography, and explains how a quantum algorithm can break it, highlighting the recent findings by Google that significantly reduce the estimated time and resources required for such an attack.
