Verified Once, Trusted Everywhere? The Problem Sign Doesn’t Solve 🤔

I often envision a specific scenario: a digital credential, issued months ago and valid at that time, seamlessly flowing through various systems. These systems, however, may not constantly re-evaluate its current relevance. This raises an interesting challenge when considering the "Sign" protocol.

Sign's architecture appears clean and reassuring. ✅ Issuers define what is true, validators confirm it, and the credential then becomes portable. This allows users to carry their verified credentials across different platforms without needing to repeat the same verification process repeatedly.
