Reference architecture for @SignOfficial (Money, ID, Capital) and how Sign Protocol + TokenTable compose across public/private rails.
Purpose
This page defines a reference architecture for S.I.G.N. deployments. It is written to be:
implementation-neutral (works with different sovereign constraints),operator-friendly (clear roles and trust boundaries),audit-ready (explicit evidence artifacts),integration-ready (legacy rails + standards).
Audience
Sovereign operators (central bank infra, GovTech platform teams)System integrators (banks/PSPs/telcos, identity vendors)Builders (wallets, program operators, auditors)
Architectural invariants
S.I.G.N. is designed around five invariants:
Controllable privacyprivate to the public,auditable to lawful authorities,minimal disclosure by default.National performancebuilt for millions of users, multi-operator workflows, strict SLAs.Sovereign controlkey custody, upgrades, emergency controls, and oversight remain under sovereign governance.Interoperabilitystandards-aligned identity (VC/DID),standards-aware payments (ISO 20022),compatibility with public + private rails.Inspection-ready evidenceevery critical action emits durable evidence:who authorized whatunder which authoritywhenbased on which identity/eligibility proofwith what rule version

Overview @SignOfficial
Sovereign-grade digital infrastructure for national systems of money, identity, and capital.
S.I.G.N. (Sovereign Infrastructure for Global Nations) is sovereign-grade digital infrastructure that governments and regulated institutions can reuse across three national systems:
New Money System — CBDC + regulated stablecoins on one national rail (public + private modes), with policy-grade controls and supervisory visibility.New ID System — national identity + verifiable credentials (VC/DID) with selective disclosure, offline verification, and strong issuer governance.New Capital System — programmable distribution + regulated real-world asset (RWA) tokenization with compliance controls and inspection-ready reporting.
Why this documentation exists
Most national digital programs fail at scale due to fragmented foundations:
identity and eligibility checks are duplicated across agencies and vendors,payments rails are opaque and hard to audit,distribution programs lack end-to-end evidence,on-chain and off-chain systems cannot be reconciled cleanly over time.
S.I.G.N. is designed as a thin but critical infrastructure layer where:
GovTech execution,FinTech rails, andcryptographic verification
meet in a way that keeps policy + oversight under sovereign control.
Who this is for
Governments, central banks, regulators
You want a system that is:
private to the public but auditable to lawful authorities,operable at national concurrency (millions of users, multi-operator),standards-aware (ISO 20022, W3C VC/DID),and deployable without vendor lock-in.

@SignOfficial is sovereign-grade digital infrastructure for national systems of money, identity, and capital. Sign Protocol provides the shared evidence layer used across deployments.
@SignOfficial is a sovereign-grade architecture for building and operating national digital infrastructure across three foundational systems:
New Money System: CBDC and regulated stablecoins operating across public and private rails with policy-grade controls and supervisory visibility
New ID System: verifiable credentials and national identity primitives enabling privacy-preserving verification at scale
New Capital System: programmatic allocation and distribution for grants, benefits, incentives, and compliant capital programs
@SignOfficial is not a product container. It is a system-level blueprint for deployments that must remain governable, auditable, and operable under national concurrency.
Across these systems, one requirement repeats: inspection-ready evidence. In many deployments, that evidence layer is implemented using Sign Protocol, an omni-chain attestation protocol for creating, retrieving, and verifying structured records.
This documentation includes:
system architecture and deployment guidance for S.I.G.N.
use case blueprints for Money, ID, and Capital
documentation for Sign products, including Sign Protocol, TokenTable, and EthSign
full developer documentation for Sign Protocol (smart contracts, SDKs, APIs, advanced topics)
If you came here for Sign Protocol developer docs, you are in the right place. The framing has expanded: S.I.G.N. describes the sovereign system architecture, and Sign Protocol is the evidence layer used across sovereign and institutional workloads. TokenTable and EthSign are standalone products that use the same core primitives and can be integrated into S.I.G.N. deployments when appropriate.
