Data is still way too siloed. One app knows one thing, another knows something else, and connecting them is always messy. You end up rebuilding the same logic over and over just to make things line up.
What caught my attention with Sign is this idea that proofs can actually reference other proofs. Not just standalone records sitting there, but linked pieces that build on each other.
So instead of re-verifying everything from scratch, you can just point to something that already exists.
That’s kind of the shift.
It lets you connect data like you’d connect nodes, not files. And because those links live inside the record itself, apps don’t have to guess or reconstruct context later.
Feels simple. But it’s not how most systems work today.
It makes everything feel less fragmented and a bit more usable.
