I moved the same verified credential between two Sign-powered apps, expecting the usual mess
rechecks, delays, someone asking me to “prove” it again.
That didn’t happen.
What clicked for me is that Sign doesn’t pass around raw data. It passes around self-contained attestations that already define how they should be trusted. The issuer logic, validity scope, and conditions travel with the credential itself.
So when another app reads it, it’s not guessing or re-verifying from zero. It’s simply evaluating whether the attestation still satisfies its own acceptance rules.
That’s a very different model from most systems where trust resets at every boundary.
Here, trust degrades by design constraints, not by distance.
Which means the network isn’t really about sharing data.
It’s about preserving meaning as that data moves.
