🔧 TheSocial-Backend

TheSocial-Backend is the backend service for the Swamajik Madhyam ecosystem, built using CQRS (Command Query Responsibility Segregation) and DDD (Domain-Driven Design) principles.
This architecture ensures scalability, clean separation of concerns, and transparency in handling social interactions.

---

🚀 Features

• ⚙️ CQRS Pattern — Separate read and write models for efficiency and scalability.
• 🧩 DDD Modules — Core business logic structured into domains (Users, Posts, Moderation, Ads, etc.).
• 🛡️ Content Moderation — Transparent pipelines with community + AI checks.
• 🔑 Authentication & Identity — Role-based access, optional decentralized identity support.
• 📊 Open Analytics — Privacy-respecting insights, visible to the community.
• 🪙 Transparent Ads — Auditable ad system with clear policies.

🏗️ Architecture

CQRS Flow

• Commands → Handle state-changing operations (create post, ban user, etc.).
• Events → Domain events that trigger reactions across services.
• Queries → Optimized read models for fast, scalable data access.

DDD Layers

1. Domain Layer — Business rules & aggregates.
2. Application Layer — Use cases, orchestration of commands/queries.
3. Infrastructure Layer — Database, message bus, external integrations.
4. API Layer — GraphQL/REST interface for apps.
