I remember trying to prove something simple across two systems.
One had my data. The other needed it.
Still… it didn’t work.
Same information existed in multiple places contracts, APIs, internal databases
but none of them could reliably verify each other.
That’s when it clicked.
Verification doesn’t fail because data is missing.
It fails because data is fragmented.
Every system holds a piece.
No system can independently confirm the whole.
So verification turns into reconciliation:
pull data → match formats → trust the source → hope nothing breaks in between.
That’s not verification.
That’s coordination risk.
And under pressure, this is exactly where things fail.
APIs desync, data versions mismatch, or one source changes and suddenly no one knows which version is true.
SIGN approaches this differently.
It doesn’t try to connect all data sources.
It turns data into verifiable claims.
Instead of asking:
“which system has the correct data?”
It asks:
“can this claim be independently verified?”
Each claim is an attestation structured and signed:
a schema → what is being proven
an issuer → who confirmed it
a verification path → how any system can check it
So systems don’t rely on cross-system data consistency anymore.
They verify a signed claim against a known schema and issuer.
Truth stops depending on where data lives.
And starts depending on whether the claim can be validated.
Most systems try to sync everything.
SIGN makes verification portable instead.
