In an official announcement, BTQ Technologies said its research paper quantified the physical cost of using quantum computing for Bitcoin mining and concluded that Grover-based quantum mining is theoretically possible but would require energy beyond current human civilization levels. According to the company, the more immediate Bitcoin risk is not mining disruption but attacks on elliptic curve digital signatures, which are used to secure wallet ownership and authorize transactions. The paper distinguishes between quantum impacts on mining efficiency and on signature security, and identifies signature-related vulnerabilities as the more pressing issue under current technological constraints.
