量子计算公司 D-Wave 首席执行官 Alan Baratz 表示,随着量子硬件继续发展,未来有能力超过当前比特币挖矿所依赖的计算设备,并可能对比特币现有工作量证明机制构成挑战。

他在接受 Yahoo Finance 采访时称,这一时间点目前仍不明确,但加密行业应在技术成熟前开始讨论量子原生替代方案。Baratz 认为,等到量子计算真正具备现实攻击能力后再应对,成本会更高。

D-Wave提出量子工作量证明方案

Baratz 同时表示,D-Wave 已展示一种新的量子工作量证明协议,试图作为比特币现有挖矿机制的替代选项。按照他的说法,这一方案基于量子优化问题,由量子系统更高效地求解。

他称,这种设计希望保留工作量证明的竞争机制,同时让挖矿过程更能抵御攻击。Baratz 还表示,该方案在能耗上大约可提升 1000 倍效率,并可能在未来成为比特币的一种可行替代路径。

现阶段仍停留在实验阶段

不过,这一提议目前仍属实验性质。比特币现有工作量证明算法已经运行多年,若要推动底层机制切换,预计会在社区内部遭遇明显阻力。

目前业内主流看法仍是,现有量子硬件距离对比特币网络形成直接威胁还有相当距离。也就是说,相关讨论更多集中在中长期风险,而非短期安全事件。

AI也被纳入密码学风险讨论

这场讨论近期还延伸到 AI 领域。此前,Anthropic 的研究提到,其 Claude Mythos Preview 模型 Eve 曾在被刻意弱化的密码算法版本中发现未知攻击方式。

这一结果推动了新的讨论:更强的 AI 系统是否会加快密码学突破,从而缩短量子威胁真正落地的时间。比特币支持者 Samson Mow 则认为,没有必要急于转向后量子密码方案。
