Quantum Computers Seizing the Bitcoin Network Could Require the Energy of a Star

Recent studies published by researchers reveal that the threat of quantum computers to Bitcoin mining and blockchain security is much farther off than previously thought due to physical limitations. Calculations show that the amount of energy needed for a successful quantum attack would be equivalent to the energy produced by a star, while many so-called quantum breakthroughs can actually be achieved with relatively simple methods.

The Massive Energy Required for Quantum Attacks
According to the research data, based on Bitcoin difficulty levels in January 2025, a quantum fleet capable of overcoming the network’s mining structure would need approximately #GateSquareAprilPostingChallenge qubits of processing power. The energy required to operate such a system is estimated at #CryptoMarketRecovery watts. This enormous figure approaches the total energy output of a star, making it an almost impossible engineering challenge when compared to the current Bitcoin network’s consumption of about 15 gigawatts.

This modeling demonstrates that claims of quantum computers destroying cryptocurrencies within seconds do not align with the laws of physics and resource constraints in the real world. Experts emphasize that Bitcoin’s security relies not only on complex mathematical formulas but also on the massive physical resources required to solve these formulas. Therefore, attacks that are theoretically possible are practically hindered by a universal energy barrier.
