BTQ Research Report: Quantum mining costs are extremely high but do not pose a threat; the real risk to BTC lies in signature security.

CoinFeed reported on April 6th that, according to PRNewswire, BTQ Technologies published a research paper titled "Kardashev Scale Quantum Computing for Bitcoin Mining," which is the first to quantitatively assess the entire physical cost of Bitcoin mining using quantum computing. The research points out that the market has long confused two types of quantum threats: one is attacks against Bitcoin's elliptic curve digital signatures (real and urgent), and the other is quantum mining accelerated based on Grover's algorithm (theoretically possible but extremely costly in practice). The research paper argues that to have a substantial impact on consensus, it is necessary to build quantum computing clusters with energy consumption far exceeding the current level of human civilization.
