The thing worth observing in SIGN is not when everything runs "smoothly", but how the system reacts when things no longer follow the original script.
In operational reality, a distribution can be completely valid at the time of creation. But the problem only begins when it needs to be adjusted or recalled after it has been shown to the recipient. At this point, most systems will switch to manual processing, external exchanges, and updating data in a way that is hard to trace, leading to no one really wanting to explain the entire process again.
SIGN addresses this weakness in a more organized manner. In TokenTable, every change, including rollbacks, is recorded as a new state version, rather than overwriting in a vague manner. The original policy is not lost but remains intact as a reference layer. In case of disputes, the entire logic can be reconstructed through Sign Protocol and verified directly on SignScan.
The important point lies here: the pressure of the system does not appear when everything goes according to plan. It appears when there are exceptions. When it needs to be explained why a decision was changed, when the issuer must prove that they still comply with the rules, and when auditors need a seamless data line rather than piecing together from many disparate sources.
SIGN makes a difference in exactly those situations. It not only ensures the correct distribution but also keeps all subsequent changes verifiable and traceable in a clear manner.
