At first glance, the chain verification feels like a settled truth in SIGN, but cancellation silently reshapes this assumption. In the SIGN protocol, the power to revoke is not just a matter of cleanup; it is an embedded authority layer within the trust model between validators and users.

What is easy to remember is that SIGN's credential verification system still respects revoked attestations at the data level, but downstream token distribution logic can immediately discard them.
A verified attestation is issued against the schema and then used, but cancellation can previously revoke the user's eligibility.
The part that truly matters is that the trust in SIGN is not just granted; it is continuously controllable.
