A Brief Introduction

Mejhool Private Messaging is a decentralized web and mobile app offering text messaging, peer-to-peer file transfer, and voice-over-IP services. Users can send text messages, make voice and video calls, and share files—images, documents, emojis, HZM stickers, and more—while ensuring complete privacy and security.

Challenges That We Faced at the Start

The client required us to create a decentralized and secure communication that would eliminate the need for a central server to control all messages. The client also wanted end-to-end encryption among their early requirements to ensure complete security on all communication channels. While the project concept is intriguing, it poses several challenges for the team.

Develop a decentralized communication app

Currently, there is a limited number of decentralized communication platforms available in the market. It meant the team had to start with a clean slate and make a fresh app layout (design and development).

#

File transfer between channels

Since the app will be decentralized, transferring files between different channels/users posed an uphill task for the team. In contrast, file transfers between users on regular apps happen through the central server.

Our Approach to Problem-Solving

The team focused on building a robust decentralized communication system using Waku and Matrix protocols. This enabled seamless chatting across web and mobile platforms, ensuring complete end-to-end encryption.

  • Real-time Communication

    Utilizing WebRTC technology allowed for high-quality audio and video calls, offering users crystal-clear conversations.

  • Message Storage and Management

    We integrated WatermelonDB for fast local database operations, ensuring quick data retrieval while enhancing security.

  • Platform Security and Privacy

    Implementing the Diffie-Hellman algorithm provided robust cryptographic security, ensuring user peace of mind.

  • Multi-Wallet Login

    Users can log in using their preferred wallet, providing a seamless Single Sign-On (SSO) experience.

Mejhool: Redefining Messaging Apps

Security and Privacy

Mejhool relies on robust cryptographic techniques to ensure impenetrable security and absolute privacy. Security in a decentralized app is a crucial aspect given the unique nature of decentralized systems. It is a multifaceted challenge requiring a comprehensive approach, incorporating blockchain technology, smart contract development, identity management, encryption, user education.

End-to-End Encryption

Communication services employ end-to-end encryption to ensure that messages are encrypted in such a way that only the intended recipients can decipher them. This means that even the service provider facilitating the communication cannot access the message content. The concept prioritizes message security and privacy while encouraging smoother user interaction.

Decentralization

Decentralization is a paradigm that distributes power and authority across a network of independent nodes. Within a decentralized system, no single entity holds complete control, which mitigates the risks associated with centralized vulnerabilities. This networked structure ensures that even if one node fails or is compromised, the overall system remains functional, preserving its integrity.
