Vitalik Buterin: @pourteaux 支持“弱登录”和“强登录”的手机操作系统也可以解决问题。 在一般设计空间中有些东西是合理的。 我真的不认为需要刷脸支付，即使它可以以某种方式完全零知识。

原推：@pourteaux A phone OS that supports “weak login” and “strong login” could also do the trick.

There’s something in that general design space that’s reasonable.

I really don’t think face payment is needed period, even if it could somehow be perfectly zero-knowledged.
