I was looking deeper into SIGN and something stood out that I didn’t notice at first.
It’s not really trying to store identity… it’s trying to standardize how trust is expressed.
Most systems today treat verification as something local. You prove something inside one app, and that proof just stays there. Another app asks you to do it again because there’s no shared format they can rely on.
SIGN approaches it differently.
It introduces schemas that act like common structures for verifiable data. Not just templates, but agreed formats that different systems can read and trust.
That changes how information moves.
Because once something is verified, it doesn’t need to be repeated. It becomes portable. Other applications can check it without re-running the whole process or asking for raw data again.
That’s where it starts to feel less like identity infrastructure and more like coordination of trust across systems.
And the interesting part is that this isn’t tied to one chain or one platform.
The data becomes composable.
So instead of rebuilding verification every time, systems can build on what already exists.
It’s a small shift in design, but it removes a lot of redundancy.
And most inefficiencies in these systems come from exactly that.
