SIGN Global: The Three Architectures Shaping the Future of Digital Identity
Digital identity is becoming a core pillar of Web3 infrastructure. @SignOfficial outlines three national identity architectures that could define how citizens interact with digital services.
1️⃣ Centralized Registry
One dominant system of record with a single verification path. It allows fast rollout and unified control, but concentrates power in one authority.
2️⃣ Federated Exchange / Broker
Multiple systems of record connected through a standard gateway. This model improves interoperability across agencies while reusing existing registries.
3️⃣ Wallet-Based Credential Model
The most Web3-aligned approach. Citizens hold their own credentials in a wallet and present proofs directly to verifiers. This improves privacy, enables offline verification, and minimizes unnecessary data sharing.
From a blockchain perspective, the wallet-first model feels closest to the philosophy of self-sovereign identity.
If digital ID becomes a global standard, which architecture wins? 👀
