The Threat of Quantum Computing to Bitcoin Security

The first part of this series delved into the physics behind quantum computing, explaining how it differs fundamentally from classical computing. However, understanding the mechanics of quantum computers doesn't directly reveal how they can be used to steal bitcoin. To grasp this, it's essential to comprehend what quantum computers are attacking - the security framework of bitcoin - and where its vulnerabilities lie. This piece begins by examining bitcoin's encryption method, known as elliptic curve cryptography, and how a quantum algorithm can exploit it, particularly highlighting the nine-minute window, as identified by Google's recent research, within which a quantum computer can potentially break bitcoin's encryption.
