I don’t think most people outside this space understand how fragmented everything is under the hood. There’s no shared memory. No consistent way to trust what already happened. One app doesn’t really “know” what you did in another unless someone rebuilds that logic again and again. So every developer ends up reinventing the same verification systems, the same indexing, the same checks and users end up repeating the same actions without even noticing why it feels exhausting.
Sign, at least from how I understand it, is trying to step into that invisible gap.
Instead of building another app people have to learn, it’s trying to build something underneath apps a layer where information, once verified, doesn’t just disappear into isolated systems. It stays. It becomes reusable. Almost like turning moments into proof that can travel with you.
I find that idea strangely human.
Because in real life, we don’t constantly re-prove who we are. If someone verifies your identity once, that trust carries forward in some form. Your documents, your reputation, your history they don’t reset every time you walk into a new room. But in crypto, they do. And maybe that’s the quiet reason why it never feels natural.
Sign’s approach feels less like “look at this new feature” and more like “what if we stopped making users start over every time.”
