System Architecture

A distributed, AI-native knowledge platform engineered for scale, verification, and global accessibility. Built with modern microservices, vector search, and edge delivery.

Version: v2.4.1 Uptime: 99.98% Latency: < 45ms p95 Nodes: 14 Regions

Distributed Layer Design

๐ŸŒ
Edge & Client
Tier 1
Cloudflare CDN WASM Frontend Edge Functions Mobile SDK

Static assets, client-side rendering, and edge-processed requests routed to nearest PoP. Sub-50ms global response times.

๐Ÿ”
API Gateway
Tier 2
Kong / NGINX Rate Limiting OAuth 2.0 / OIDC GraphQL Federation

Unified entry point handling authentication, request routing, throttling, and protocol translation between clients and services.

๐Ÿง 
AI & Processing
Tier 3
Semantic Search NLP Pipeline Knowledge Graph Engine Fact-Verification

Core intelligence layer. Processes queries, resolves entity relationships, validates claims against primary sources, and generates enriched responses.

๐Ÿ—„๏ธ
Data & Storage
Tier 4
Vector DB (Milvus) PostgreSQL Neo4j Graph Redis Cache

Multi-model storage architecture. Structured metadata, high-dimensional embeddings, relational article data, and real-time caching layers.

Query to Knowledge

1

Ingest & Parse

Client request hits edge node. Natural language is tokenized, entities extracted, and intent classified via lightweight transformer.

โ†’
2

Graph Resolution

Knowledge graph traverses related concepts. Cross-references are mapped across disciplines, languages, and historical contexts.

โ†’
3

Verification

Claims are cross-checked against primary sources, peer-reviewed datasets, and editorial consensus layers before scoring.

โ†’
4

Delivery

Structured response is assembled, cached at edge, and delivered with citation metadata, interactive graphs, and multilingual fallbacks.

Security Architecture

๐Ÿ›ก๏ธ

Zero-Trust Network

Service-to-service mTLS, short-lived JWTs, and strict RBAC policies across all microservices and data planes.

๐Ÿ”’

End-to-End Encryption

AES-256 at rest, TLS 1.3 in transit, and client-side encryption for sensitive contributor submissions.

๐Ÿ“œ

Compliance Ready

SOC 2 Type II, GDPR, CCPA, and WCAG 2.1 AA compliant. Automated audit logging and data retention policies.

๐Ÿงช

Adversarial Testing

Continuous red-teaming, prompt injection guards, and ML model evaluation pipelines to prevent hallucination or bias drift.
