I have been thinking about this for some time. One idea keeps coming back. Same credential. Different issuers.
It sounds simple. But it does not feel right.
Systems like SIGN treat credentials like truth. An issuer creates it and signs it. Anyone can check it. It looks clean. It looks reliable.
So we assume that if two credentials look the same then they mean the same.
But that is not how the real world works.
Different issuers follow different rules.
Think about a simple example. A professional certification.
One issuer may require hard exams and real work experience. It takes time and effort.
Another issuer may give the same certification after a short course.
Now here is the problem.
Both credentials can look exactly the same. Same structure. Same data. Same proof.
Everything checks out.
But the value is not the same.
And the system cannot see that.
From the system view both are valid. That is it.
The real difference comes from how the issuer created it.
This is where things get tricky.
Now the verifier has to think more.
It is not just about checking if it is valid.
It becomes about understanding what it really means.
And that is much harder.
People do not talk about this enough.
Because now we add another layer. That layer is human judgment.
And human judgment is not always the same.
Now think bigger.
Different countries. Different industries. Different standards.
Everyone is looking at credentials that seem the same.
But they are not.
So what happens next.
We try to create common standards. That is slow and difficult.
We try to build trust systems.
Or we leave the problem to the person who is checking.
People say this can scale.
But it does not feel easy.
Because now consistency depends on people working together. And that is never simple.
Here is what matters most.
Systems like SIGN make credentials easy to share. Easy to verify.
But just because something can be verified does not mean it has the same value everywhere.
That is the gap.
So what happens in the future.
Can these systems stay clear and consistent.
Or will we reach a point where everything looks valid.
But the meaning slowly changes.
I think this question is still open.
