People keep putting Sign in the “identity tool” box, but that feels way too limited. What’s happening here looks a lot bigger than that.
It’s starting to feel more like an evidence layer for systems that actually need to prove what they’re doing, especially once regulators start paying attention.
Look at stuff like cross-border payments or public infrastructure. You can’t run on vague data forever. At some point, you need a real trail. Something verifiable. Something tied back to an actual issuer.
And honestly, that’s the bigger shift. Apps probably won’t keep stockpiling raw user data the way they do now. They’ll just point to signed data that can move and be reused across chains.
That changes a lot. Not just for identity, but for how accountability works across the whole system.
