Bitcoin Quantum Mining Research Report: Actual Costs "Astronomical," Real Risk Lies in Signature Vulnerabilities

Odaily News BTQ Technologies has released a research paper titled "Kardashev Scale Quantum Computing for Bitcoin Mining," which for the first time quantifies the full-process physical costs of using quantum computing for Bitcoin mining. The related research points out that the market has long confused two types of quantum threats: one is attacks targeting Bitcoin's Elliptic Curve Digital Signature Algorithm (ECDSA) (realistic and urgent), and the other is quantum mining accelerated by Grover's algorithm (theoretically possible but with extremely high practical costs).

The research paper argues that to have a substantial impact on consensus, it would require building a quantum computing cluster with energy consumption far exceeding the current level of human civilization. The study also proposes an open-source resource estimation model covering key aspects such as reversible double SHA-256 computation, fault-tolerant quantum error correction, and large-scale qubit scheduling. The conclusion emphasizes that the more realistic risk facing Bitcoin comes from cryptographic signature vulnerabilities, not quantum mining capabilities. (PRNewswire)
