Zakura says its open-source Common libraries reduced that process from more than three seconds to below 200 milliseconds in some tests. On the team’s benchmark hardware, mobile proof generation ran more than 14 times faster, while desktop generation improved by more than five times.

The results come from Zakura’s own testing rathe...
