I’ve spent some time looking into digital identity systems, and honestly, the biggest issue isn’t which model a country chooses. Centralized, federated, wallet-based… they all sound good until they hit real-world scale.
What I’ve seen is most systems either move fast but expose too much data, or protect privacy but struggle operationally. That tradeoff keeps repeating.
That’s why SIGN caught my attention. Instead of replacing everything, it focuses on the layer underneath the trust layer. Who can issue credentials, what gets shared, how it’s verified, and how it holds up in audits.
From my perspective, that’s where things usually break.
If proofs move instead of raw data, and verification stays reliable even offline, you start solving real problems, not just designing theory.
Still early, but this feels less like hype and more like infrastructure quietly taking shape.
