Coinbase披露稱,量子運算目前不會對比特幣構成立即威脅,但產業需要提前為未來遷移做準備。該公司已聯合多家機構成立“比特幣安全聯盟”,並公佈自身面向後量子時代的技術路線。

聯合多個機構成立安全聯盟

Coinbase CEO布萊恩阿姆斯壯在 X 平台表示,這項聯盟由 Coinbase 發起,並獲得貝萊德、Fidelity Digital Assets、Block、Blockstream、Strategy 等機構支持。目標是圍繞比特幣長期安全展開協作,為未來可能出現的高性能量子電腦提前準備。

Coinbase表示,後量子風險並不在眼前,但真正困難不只是演算法替換,而是如何在去中心化網路中完成大規模、安全遷移。比特幣網路涉及數以百萬計的用戶,任何升級都需要廣泛協調。

Coinbase公佈內部技術路線

該公司披露稱,Coinbase已發布一份後量子路線圖,並在開發抗量子版本的自有密鑰管理系統 PQ-CoreKMS。該公司認為,具備容錯能力的量子電腦最終大概率會出現,因此現在開始準備更現實。

根據安排,Coinbase將從 8 月起與 Bitcoin Core 開發者、密碼學家和研究人員共同舉行工作會議,討論遷移方案。公司也承諾投入工程資源和資金,支持相關研究與實施準備。

目前威脅尚遠但準備視窗已開啟

文章提到,美國國家標準與技術研究院(NIST)近年來已完成首批後量子密碼演算法的遴選與標準化。政府和科技公司也已開始推動關鍵基礎設施向新標準過渡。

就比特幣而言,現階段量子電腦距離破解其橢圓曲線密碼體系仍有明顯差距。業界普遍認為,真正具備攻擊能力的系統需要數百萬個高品質實體量子比特,並配合穩定的糾錯能力,這仍遠遠超出當前水準。

不過,關於這類系統何時出現,業界並無明確時間表。圍繞比特幣的潛在遷移方案,開發者已提出多種方向,包括引入抗量子簽名方案、推動用戶將資金轉入升級後的地址,以及透過未來的比特幣改進提案推進協議層調整。

這也意味著,相關工作的重點暫時不是處理短期攻擊,而是儘早建立協作機制,降低未來集中遷移時的技術和治理難度。

補充資料:文中提到的聯盟成員除 Coinbase 外,還包括貝萊德、Fidelity Digital Assets、Block、Blockstream 和 Strategy 等大型產業參與者。
