One thing that doesn’t get talked about enough with $SIGN …
Attestations aren’t permanent.
They behave more like state than truth.
They can expire, change, or get revoked
and that status needs to be tracked over time.
That matters because trust isn’t fixed anymore.
It shifts.
Someone verified today might not be valid tomorrow and systems need to reflect that in real time.
Sign actually builds around this idea.
Not static data, but proof that evolves.
So it’s not just about verifying something once it’s about verifying what’s true right now.
And there’s a deeper shift happening underneath.
Systems are slowly moving away from storing everything themselves.
Instead, they check what can already be proven elsewhere.
No need to duplicate data
No need to re-verify from scratch
Just reference proof when needed.
That flips the model.
Systems aren’t the source of truth anymore
they’re more like interfaces that read from it.
You don’t carry the data
you carry something that can be verified anywhere.
It’s a quiet change, but a big one.
Infrastructure isn’t being built around storage anymore it’s being built around verification.
