《Hashkey Capital: The Latest Advances in Quantum Computing and Their Impact on the Crypto Industry》 Google Quantum AI's latest white paper has lowered the resource threshold for breaking the core encryption systems of cryptocurrencies to approximately 500,000 physical qubits, a reduction of about 20 times compared to previous estimates. This means the quantum threat has shifted from a long-term assumption to a quantifiable mid-term risk. Current attacks primarily target signature mechanisms based on Elliptic Curve Cryptography, including transaction-in-transit attacks and static asset attacks. The report states that approximately 6.9 million BTC (about 33% of the total supply) and numerous Ethereum accounts have exposed their public keys, posing potential risks. Although hardware gaps remain, algorithm optimization continues to advance, and Q-Day may occur between 2028–2035. The migration bottleneck lies in governance rather than technology.
