I was going through SIGN’s structure and something stood out to me. It’s not really trying to “store” identity better.
It’s trying to remove the need to keep asking for it.
Most systems treat verification like a repeated step. Every new app, same checks again. Same friction, same forms, same delays. Nothing carries over.
SIGN flips that by turning verification into something reusable.
Once a credential is issued, it doesn’t stay locked inside one platform. Other systems can read it, verify it, and move on without restarting the process.
That’s already useful.
But the part that feels bigger is how it standardizes the data itself.
Schemas aren’t just structures. They act like shared agreements across systems. So different apps don’t just accept the same proof… they understand it the same way.
That makes things composable.
Identity, participation, even reputation can move across environments instead of getting reset every time.
It ends up feeling less like managing users.
And more like making trust portable.
Which, honestly, is something most systems still don’t get right.
