量子机算机的问世是对比特币之类数字货币的一个威胁。比特币的算法可能会被量了机破解，当然，其它的币种可能更不安全。那么如何来对抗可能存在的危险呢？毫无疑问，当然是改变算法了。以数字图形技术来代替数字签名不失为一个方案。
That's because quantum computers have the ability to unwind much of the cryptography that underlies how data - including cryptocurrency private keys - passes through the internet. As such, researchers in the space are playing it safe, already looking for ways to re-architect cryptocurrency systems to be resistant to quantum computing.
