Quantum Computing & Bitcoin Security: No Imminent Threat

Elon Musk recently raised concerns about quantum computing potentially cracking Bitcoin’s SHA-256 encryption, following new research from IBM. In response, Grok referenced insights from NIST, IBM, and top cryptography experts: the chance of quantum computers breaking SHA-256 in the next five years is virtually zero. Even by 2035, the probability stays under 10%, as doing so would require millions of error-correcting qubits — far beyond the 1,000 noisy qubits today’s systems can handle.

Bitcoin’s hash algorithm remains safe — for now.
