Main takeaway: D-Wave CEO Alan Baratz warned quantum computers could eventually break Bitcoin's proof-of-work and urged exploring quantum-native alternatives. He said D-Wave demoed a quantum proof-of-work based on optimization that may be ~1000x more energy efficient, is experimental, and could face community resistance; most experts say current quantum hardware is not yet a direct threat.
币界网消息,D-Wave首席执行官Alan Baratz在接受Yahoo Finance采访时警告,量子计算最终将能够破解比特币的工作量证明协议。他表示,足够先进的量子计算机将超越当前用于挖矿的硬件。尽管时间表尚不明确,但他认为加密货币行业应开始考虑量子原生替代方案。Baratz还声称,D-Wave已经展示了一种新的量子工作量证明协议,可能作为比特币现有挖矿机制的替代方案,该协议依赖于量子优化问题,能够被量子系统高效解决。他表示,这种方法的能效约为现有机制的1000倍。尽管目前该提案仍处于实验阶段,但他认为这种协议最终可能成为比特币的可行替代方案。比特币的当前工作量证明算法已经运行多年,这一潜在转变可能会遭到社区的强烈反对。大多数专家认为,当前的量子硬件仍远未对网络构成直接威胁。
