[Platform Architecture]

The platform architecture plays a crucial role in understanding the core structure and functionality of the Karma system. This section provides a detailed explanation of the infrastructure and implementation of the actual messenger system, covering cloud infrastructure, blockchain infrastructure, microservices architecture, security architecture, database architecture, personal media architecture, and unified client architecture.

1) Cloud Infrastructure

The Karma system employs a public cloud-based architecture to efficiently handle a large number of concurrent users and high volumes of user requests. It ensures the secure storage and management of all user data through data replication across regions and availability zones. The Karma system containerizes all services and utilizes container orchestration technologies such as Kubernetes to automate the deployment and operation of various services, automatically tuning the infrastructure in response to user load, thereby flexibly managing infrastructure operating costs.

2) Blockchain Infrastructure

The Karma system integrates with the Fognet blockchain's Wallet, DEX, and DeFi services to implement security services, payment services, and P2P services.

3) Security Architecture

The Karma system securely protects customer personal information, messages, and content through AES256 encryption. All communication with clients is encrypted via HTTPS (SSL/TLS), messages between users are encrypted end-to-end, and all user content (photos, videos, files) is encrypted with the AES256 algorithm. Encryption keys are protected and verified for integrity using ECDSA signatures issued to individual users. Unique user identification information (Blockchain ID) and encryption keys are managed by the security architecture using unique IDs and encryption keys generated by the Fognet blockchain system.

4) Database Architecture

To efficiently manage a large number of users and high volumes of data, the Karma system stores and manages all user profiles, messages, content, files, and other data using appropriate relational database technologies and NoSQL technologies. Additionally, a big data system can be established to utilize user messages and content.

5) Personal Media Architecture

The Karma system supports an architecture that efficiently registers and distributes various user-generated content (live broadcasts, videos, photos). This allows for high-performance and secure personal media services through AI live platforms, AI video editing and uploading, real-time live chat, harmful content filtering technologies, and integration with external CDNs.

6) Unified Client Architecture

The Karma system provides a unified client that delivers efficient and consistent services across various client platforms, including mobile, desktop, and web. The Karma system supports a hybrid client architecture that integrates native and cross-platform architectures for each client environment.
