BTQ releases research on quantum Bitcoin mining: actual costs are "astronomical," and the real risk lies in signature vulnerabilities
According to PR Newswire, BTQ Technologies has released a research paper titled "Kardashev Scale Quantum Computing for btc-42">Bitcoin Mining," which quantifies the physical costs of the entire process of using quantum computing for Bitcoin mining for the first time. The related research points out that the market has long confused two types of quantum threats: one is the attack on Bitcoin's elliptic curve digital signatures (real and urgent), and the other is quantum mining accelerated by Grover's algorithm (theoretically possible but with extremely high practical costs).
The BTQ paper argues that to have a substantial impact on consensus, a quantum computing cluster with energy consumption far exceeding the current level of human civilization needs to be built. 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 quantum bit scheduling. The conclusion emphasizes that the more realistic risk facing Bitcoin comes from vulnerabilities in cryptographic signatures, rather than quantum mining capabilities.
