Sign Protocol doesn’t begin with identity, it just uses it as the first doorway.
What really stands out to me is how it turns trust into something structured and reusable. Schemas aren’t just templates, they act like shared agreements between systems. Once data fits that format, it stops being locked in one place and starts becoming composable across different environments.
That shift is bigger than it looks. It means reputation, credentials, even behavior history can actually move with you instead of resetting every time you switch platforms. Most systems don’t fail at verification, they fail at continuity. Sign is clearly aiming at that gap.
And when continuity improves, the user experience changes quietly but deeply. Less repetition, less friction, more flow between systems that normally don’t talk to each other.
Maybe it sounds simple on the surface, but improving how trust travels is where real infrastructure gets built. That’s not just identity, that’s the UX layer of trust itself.
That’s where the moat starts forming.
