Everyone keeps calling Sign Protocol an identity tool. That framing misses the point.
The real problem isn’t who you are. It’s whether what’s already been verified about you actually counts somewhere else.
Look at something like e-Visa issuance. You upload documents, wait, re-upload when something fails, and sit in opaque review loops. Each system re-checks everything from scratch because nothing is reusable.
That’s not a data problem. That’s a coordination failure.
Sign starts to make more sense as an evidence layer. Documents and approvals become structured attestations, signed by issuers under defined schemas. Now another system doesn’t need to repeat the entire process. It checks the issuer, the schema, and decides if that evidence is acceptable.
Of course, systems still fail. Things break, and when they do, users need real support, not automation loops.
But the direction is clear. Less repetition. More accountability.
And finally, a system where verified data actually counts.
