量子運算公司 D-Wave 執行長 Alan Baratz 表示,隨著量子硬體持續發展,未來有能力超過目前比特幣挖礦所依賴的運算設備,並可能對比特幣現有工作量證明機制構成挑戰。

他在接受 Yahoo Finance 採訪時稱,這一時間點目前仍不明確,但加密產業應在技術成熟前開始討論量子原生替代方案。 Baratz 認為,等到量子運算真正具備現實攻擊能力後再應對,成本會更高。

D-Wave提出量子工作量證明方案

Baratz 同時表示,D-Wave 已展示一種新的量子工作量證明協議,試圖作為比特幣現有挖礦機制的替代選項。按照他的說法,這個方案是基於量子最佳化問題,由量子系統更有效率地求解。

他稱,這種設計希望保留工作量證明的競爭機制,同時讓挖礦過程更能抵禦攻擊。 Baratz 也表示,該方案在能耗上大約可提升 1000 倍效率,並可能在未來成為比特幣的一種可行替代路徑。

現階段仍停留在實驗階段

不過,這項提議目前仍屬實驗性質。比特幣現有工作量證明演算法已經運作多年,若要推動底層機制切換,預計會在社群內部遭遇明顯阻力。

目前業界主流看法仍是,現有量子硬體距離對比特幣網路形成直接威脅仍有相當距離。也就是說,相關討論較集中在中長期風險,而非短期安全事件。

AI也被納入密碼學風險討論

這場討論近期也延伸到 AI 領域。先前,Anthropic 的研究提到,其 Claude Mythos Preview 模型 Eve 曾在被刻意弱化的密碼演算法版本中發現未知攻擊方式。

這個結果推動了新的討論:更強的 AI 系統是否會加快密碼學突破,從而縮短量子威脅真正落地的時間。比特幣支持者 Samson Mow 則認為,沒有必要急於轉向後量子密碼方案。
