The more I read about $SIGN the more I think the “ID” part is overrated.
What actually feels powerful to me is the Evidence Layer.
Not “who are you?” — but “what can you prove?”
That’s a big shift.
If attestations become portable, it means your work, eligibility, approvals, and history can move across apps without re-verifying from scratch every time. No more screenshots. No more “trust me bro.” Just proof.
And at sovereign scale, that’s the difference between chaos and coordination:
who approved it, under what authority, and what rule-set was used.
If $SIGN nails this part, it’s not just another token. It’s a memory layer for real systems.
