One thing that doesn’t get enough attention in digital systems is this: trust doesn’t last forever.

Most systems treat verification as permanent — once something is verified, it stays valid forever. But in real life, that’s not how things work. Eligibility changes, permissions expire, and conditions evolve over time. A document or status that was valid last year might mean nothing today.

Sign Protocol seems to approach this problem in a more practical way. It introduces time-based attestations, where verification is tied to a specific validity period. After that time passes, the attestation is no longer automatically accepted unless it’s renewed.

For example, if access to a service is approved for a limited period, a time-bound attestation can let that access expire automatically — without needing any manual checks later. The same applies to programs, rewards, or any condition that shouldn’t stay open forever.

In my view, this approach feels much more aligned with how the real world actually works. It reduces the risk of outdated data being reused and removes the need for constant manual reviews.

At the same time, it raises a practical question: if trust can expire by design, are systems truly ready to handle continuous re-verification in a smooth and user-friendly way?@SignOfficial $SIGN $BASED $SIREN #signdigitalsovereigninfra
