Most sovereign blockchain projects sell you three solutions. An identity system, a payment rail, a distribution engine. Each with its own database, compliance logic, audit trail, and integration cost. You buy all three, spend months wiring them together, and end up with broken audit trails every time data crosses between them.
Sign.global built one stack instead.
The foundation is Sign Protocol as a single evidence layer. Every operation across identity, money, and capital runs on the same attestation standard. That design decision is what makes the unified flow possible.
Here's what that looks like in practice. A citizen receives a Verifiable Credential in SignPass — that's an attestation. The Programmable Rules Engine reads that same attestation directly. If policy conditions match, conditional payment triggers automatically. TokenTable reads the same attestation for eligibility, executes the capital distribution, and creates a settlement attestation that closes the loop. One proof, one rule check, one capital movement, one new proof. No middleware. No custom bridges. No separate compliance contract for each layer.
Because all three layers share the same schema standard, the entire flow is atomic. Privacy holds consistently too — Zero-Knowledge Selective Disclosure works across the full stack, not just the identity layer. Every step produces an immutable attestation, so audit visibility is automatic rather than something bolted on afterward.
The Dual-Rail architecture keeps sovereign control intact throughout. Sensitive operations stay on Private Rail under full government node ownership. Settlement and verification can cross to Public Rail for liquidity without breaking the unified flow.
The honest pushback: one-stack simplicity works cleanly for use cases Sign Protocol's schemas already support well. Novel sovereign deployments with complex edge cases still require custom schema design upfront. The stack doesn't eliminate policy complexity — it just executes it more efficiently once the rules are defined.
Treating identity, money, and capital as separate systems made sense when no single evidence layer connected them. That excuse is gone now.
