印象中,比特币用的数字签名不能被量子计算机破解。不过PoW什么时候被攻破还不好说
可以暴力破解

这个还轮不到比特币担心,即使量子计算机能应用,一定会有对抗算法。
是的,再不行就硬分叉

那要比谁快了,目前看距离商用还遥远,但军用和科研不会太远了,进入这个阶段央妈就可以动用破解全部私钥。时间不等人啊,对抗算法要力争在一年内实现。

好像已经有币开始ico了,专门对抗量子的

就算有量子计算机,也只会拿来挖矿啊,几百亿的市场,挖矿盈利多好,去破解有什么意义?
破解可以做空啊

这件事,莱特要走在前面了,莱特的隔离验证激活后,抗量子也是它要升级的众多目标之一。所以比特不能等了。
莱特为比特做实验

用这个挖矿太奢侈了, Grin
肯定不用这挖矿啊,破解密钥去了

一个私钥使用过一次就能攻破了,所以btc设计为一个地址只使用一次的

一个私钥使用过一次就能攻破了?是真的?

目前貌似已经有了对抗量子的算法了。小蚁ANS已经在研究测试。

技术是不断发展的,密码学现在已经有了对抗量子的算法,未来区块链肯定会有对抗量子的更多的新型算法出现
