外媒稱,比特幣回落至 6.3 萬美元附近後,市場討論焦點不只停留在價格下跌本身,也重新轉向量子運算可能帶來的加密安全壓力。文章認為,隨著量子技術逐步進入商業應用,所謂「Q-Day」正被更頻繁地提起。

比特幣下跌伴隨大額強平

通報提到,當比特幣跌向 6.3 萬美元時,市場出現約 1 億美元的強制平倉。此次回落並非單一因素推動,韓國 KOSPI 指數走弱、半導體板塊拋售,以及市場等待聯準會會議結果,都被視為短線壓力來源。

在這一背景下,量子運算話題再次進入加密市場視野。文章引述部分業內人士說法稱,去中心化網路依賴公開金鑰體系,若量子運算能力繼續提升,區塊鏈協議可能成為較早面臨壓力的對象。

AT&T與 D-Wave 合作引發討論

這輪討論的直接觸發點,是 AT&T 與 D-Wave Quantum 擴大合作。根據報導,AT&T 已將量子退火技術用於網路最佳化演算法。文章藉此強調,量子運算正從實驗室研究走向實際商業場景,而不再只是遠期概念。

報告認為,這類商業落地案例會加速市場對量子安全問題的重視,尤其是在加密資產領域。原因在於,比特幣等區塊鏈網路的安全性,建立在現有密碼學假設之上,一旦底層假設被突破,影響範圍可能較廣。

「Q-Day」時間表進一步提前

  • Google 研究人員據稱將相關算力預估下調約 20 倍
  • 新估算認為所需實體量子位元可低於 50 萬個
  • 美國能源部預計未來三年內可能出現更強量子計算機

此外,IBM 和微軟等公司也被提及正在為 2029 年前後更具實際密碼學意義的量子系統做準備。文章據此認為,市場擔憂的重點已不只是技術是否會出現,而是加密社群能否在風險真正到來前推進加密升級。
