Governance
National Digital Addressing System (NDAS)
Role
The foundational addressing layer. Deterministic AIG-CTG codes for every person, place, and asset in Nigeria. LGA-centric, federated. The universal identifier substrate for the entire ecosystem.
Inputs
→ Location data
→ LGA boundaries
→ Legacy addresses
Outputs
← AIG-CTG address code
← Reverse geocoding API
← Coverage grid
Cryptographic Verification & Identity Layer
Role
Backend verification and cryptographic logic for the entire trust layer. Receives address-anchored identity claims and issues verifiable proofs consumed by DTM/DTM2 and CTM. Never the UI — always the engine.
Inputs
→ AIG-CTG address
→ Identity claim
→ Document proof
Outputs
← Verification proof
← Trust signal
← Audit trail
Digital Trust Mark & Trust Map
Role
The client-facing trust credential. DTM is the issuable mark for individuals and entities. DTM2 is the map-based trust overlay. Strictly the presentation layer receives proofs from CRYLID, no backend logic.
Inputs
→ CRYLID verification proof
Outputs
← Digital Trust Mark
← Map overlay layer
← Public query API
CRYLID Trust Map Registry & API Services
Role
Scalable trust registry and API services mesh. Handles bulk trust mark queries, registry lookups, and API subscriptions for institutional consumers. Pure services layer with no UI. Avoid microservice sprawl until demand is proven.
Inputs
→ CRYLID proofs
→ AIG-CTG addresses
→ Institution credentials
Outputs
← Registry API
← Bulk query service
← Webhook events
Cadastral Navigation & Geospatial Intelligence
Role
Geospatial cadastral navigation on an OSM base with AIG-CTG grid overlays. Land boundaries, infrastructure mapping, and a telco-assisted ground-truth cadastre programme for coverage and accuracy acceleration.
Inputs
→ OSM data
→ AIG-CTG grid
→ Ground-truth surveys
Outputs
← Cadastral map
← Boundary layers
← Coverage API
Property Title Verification Marketplace
Role
Property title authentication and verification marketplace. Registry integration, finance linkage, and diaspora module for remote property investment. Built on NINjaMap cadastral data with CRYLID trust marks.
Inputs
→ NINjaMap cadastre
→ Registry data
→ CRYLID trust
Outputs
← Verified title
← Investment documentation
← Diaspora portal
LGA Identity & Address Management
Role
Local Government identity and address management. Enables property tax administration, resident identity verification, governance operations, and service delivery routing at LGA level.
Inputs
→ AIG-CTG codes
→ LGA resident data
→ Property records
Outputs
← LG identity record
← Property tax base
← Service routing
Sovereign Governance & Security Intelligence Framework
Role
Umbrella governance and security intelligence framework across all 774 LGAs. Cyber incident monitoring, institutional mapping, data security posture, and multi-agency coordination of the sovereign oversight layer.
Inputs
→ All module telemetry
→ Institutional mapping
→ Incident reports
Outputs
← Security intelligence
← Audit reports
← Incident response
