A Brief Introduction

Mejhool Private Messaging is a Decentralized web and mobile app with text messaging, peer-to-peer file transfer, and voice-over-IP service. It allows users to send text, make voice and video calls, and share files – images, documents, emojis, HZM stickers, and many more while keeping the client’s privacy intact.

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 Solution

We focused on creating a robust decentralized communication system, achieved through a combination of Waku and Matrix protocols. These enable smooth chatting across web and mobile platforms, allowing users to connect anytime, anywhere. Since a decentralized app must offer security with high interoperability, the team ensured complete end-to-end encryption. Meanwhile, the design team spent time creating a coherent design that integrated functionality with a sound user experience.

  • Real-time Communication

    The team utilized WebRTC technology to enable high-quality audio/video calls similar to apps like WhatsApp. It allowed users to engage in crystal-clear conversations every time.

  • Message Storage and Management

    We integrated WatermelonDB to provide lightning-fast local database operations. It allowed data to be stored locally to speed up retrievals and offer an extra security layer.

  • Platform Security and Privacy

    We implemented the Diffie-Hellman algorithm, a robust cryptographic technique, to ensure high security and give users peace of mind while interacting within the app.

  • Multi-Wallet Login

    With multi-wallet login functionality, users can use their preferred wallet to log in, enjoying a seamless Single Sign-On (SSO) experience.

  • File Transfer

    The team implemented PeerJS to enable full peer-to-peer file transfers. It ensures exclusive file accessibility to the intended recipient without storing, thus maintaining privacy and security.

Excellent Features that Shape Mejhool

Our developers studied market status and audience response to understand and create a one-of-a-kind solution. Each feature adds to the app's quality and creates a cohesive environment. This enables users to interact with Mejhool and exploit its capabilities freely.

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.
