Sign Protocol: The Cryptographic Evidence Layer
After studying Sign.global’s docs, it’s clear: Sign Protocol is the cryptographic evidence layer of the entire S.I.G.N. stack, sovereign infrastructure for nations.
It lets governments and developers define structured schemas, issue verifiable attestations, and anchor tamper-proof evidence across chains with selective disclosure and easy querying via SignScan.
It powers New ID System (credentials), New Money System (CBDC proofs), and New Capital System (audits).
My take:
Pros : Real standardization, privacy, and auditability for national digital systems.
Cons : Adoption depends on government buy-in and legacy integration.
This feels like the missing trust backbone for Blockchain for Nations.
What do you think, should countries build on this evidence layer?
