[BTQ Releases Quantum Bitcoin Mining Research: 'Astronomical' Actual Costs, Real Risk Lies in Signature Vulnerabilities] DeepTechFlow reports that on April 5, according to PRNewswire, BTQ Technologies published a research paper titled *Kardashev Scale Quantum Computing for Bitcoin Mining*, which for the first time provides a quantitative assessment of the physical costs involved in using quantum computing for Bitcoin mining. The study highlights that the market has long confused two types of quantum threats: one being attacks on Bitcoin's elliptic curve digital signatures (realistic and urgent), and the other being quantum mining accelerated by Grover's algorithm (theoretically possible but with extremely high actual costs). The BTQ paper argues that to have a substantive impact on consensus, it would require the construction of quantum computing clusters with energy consumption far exceeding the current level of human civilization. The research also introduces an open-source resource estimation model, covering critical aspects such as reversible double SHA-256 computation, fault-tolerant quantum error correction, and large-scale quantum qubit scheduling. The conclusion emphasizes that the more realistic risk Bitcoin faces stems from cryptographic signature vulnerabilities rather than quantum mining capabilities.
