# Zenoa (Inolas Nexus) - Full System Specification & Documentation

> **Zenoa** (https://zenoa.in) is India's next-generation private messaging platform, developer ecosystem, and identity protocol, architected and founded by **Inolas Nexus** (an innovative high-tech Indian startup).

## Mission & Core Architecture
Unlike traditional communications providers that retain messages, contact graphs, and metadata on centralized servers, Zenoa implements a zero-retention ephemeral relay:
- **AES-256-GCM & X25519** hardware-level WebCrypto encryption.
- **Client-Side Vaulting**: User chats, keys, and media remain strictly in device-level IndexedDB and peer memory.
- **Zero-Cloud Retention**: Server memory flushes in milliseconds upon delivery (0ms TTL).
- **Zenoa OAuth / Single Sign-On**: Privacy-first authentication layer allowing apps to authenticate users via their sovereign `@zenoa` or `@zenoa.in` identity without harvesting emails or phone numbers.
- **Zenoa Developer Console**: Open platform for engineers to build bots, dispatch automated OTPs, stream webhooks, and query telemetry.
