量子计算如何影响加密货币

Currently, quantum computing has negligible direct effect on cryptocurrency. However, its long-term development poses a significant theoretical threat to the cryptographic security underpinning most digital assets.

Current State of Play

As of 2026, quantum computing's influence on the broader financial system, including cryptocurrencies, remains extremely low, with an influence score of 1/100. While progress is noted, such as IBM connecting its first modular cryogenic systems in a milestone toward fault-tolerant quantum computing, the technology is not yet realized at scale. Its primary geopolitical relevance is currently linked to the United States and national security applications.

Future Threat Assessment

Analysts widely expect that sufficiently powerful quantum computers could eventually compromise the elliptic curve cryptography and hashing algorithms used in many cryptocurrencies. This would allow for theft or manipulation of assets. Efforts are underway to develop "quantum-resistant" cryptography, but widespread adoption across existing blockchain networks would be a complex and lengthy process.
