#signdigitalsovereigninfra $SIGN @SignOfficial
I didn’t expect schemas to be the thing that bothered me.
Everyone talks about moving data between systems.
But when I looked closer, the data was already there.
It just didn’t mean the same thing everywhere.
I’ve seen the same claim pass in one system and get rejected in another.
Nothing changed in the data.
Only the interpretation did.
That’s the gap SIGN is actually closing.
A schema here isn’t just format.
It fixes what a claim is allowed to mean before it’s even issued.
That rigidity feels limiting at first.
But without it, every system rewrites the claim in its own way.
So every attestation carries:
– who said it
– under which schema
– what exactly was signed
And that changes how systems behave.
A health authority can issue an eligibility proof,
and a bank can consume it later without rewriting logic around it.
No mapping layers. No silent assumptions.
Because once meaning is fixed at issuance,
every verifier is forced to read the same claim the same way.
That’s when it clicked for me:
The problem was never sharing data.
It was trusting that everyone reads it the same way.
