But once you see the actual problem it solves you start noticing it everywhere.

That is not a technical failure. That is a design gap that most infrastructure just accepts as normal.
In regions like the Middle East where digital systems are scaling fast and connecting constantly that reset becomes expensive. Not in a dramatic way but in the quiet way where every extra check adds delay, every repeated validation adds cost, and the people on the other end just feel friction without knowing why.
$SIGN is built specifically around that handoff moment. Instead of verification data losing its meaning when it crosses from one system to another, Sign creates a layer where what has already been proven stays proven. SIgn what keeps that validation layer economically aligned and functional as it scales.
It is not changing how any single system works internally. It is changing whether systems can actually recognize each other's work. That distinction sounds small but it is usually the exact thing that turns a fast region into a slow one.
The part I find genuinely interesting is whether this becomes invisible infrastructure the way DNS did, something everyone depends on that almost nobody thinks about. Would be curious if anyone else has run into that same reset pattern in their own workflows.
