Sign’s Three Families of Digital Trust: None Wins Alone
In the real world, identity isn’t one-size-fits-all.
Think of it like this:
- Your PAN card is a Centralized Registry (A) — one government database, one verification path. Fast, uniform, but rigid.
- Inter-bank UPI transfers are Federated (B) — different banks talk through a common gateway without copying each other’s data.
- Your DigiLocker or phone wallet is Wallet-first (C) — you hold your own proofs and share only what’s needed. Private and offline-friendly.
Most countries pick one and force it on everyone. Sign says: stop choosing.
Even the most wallet-forward system still needs a shared trust layer.
Even the most centralized database needs interoperability.
Even the best exchange needs a way to prove facts without copying entire records.
That’s why Sign builds all three families together, Sovereign Infrastructure for Global Nations (S.I.G.N.).
Real digital nations don’t live in one mode. They live in all three.
Smart architecture isn’t about picking a winner. It’s about making sure none fails alone.
