# 🚀 BlockMeet: The Decentralized Video Conferencing Revolution 🌐

Welcome to **BlockMeet**, where video conferencing meets decentralization! 🎉 Designed for secure, small-group communication, BlockMeet is perfect for private discussions, sensitive collaborations, and modern tech enthusiasts. Let’s dive in!  

---

## 🛠️ Features  

### 🎥 Live Video Conferencing  

Enjoy smooth and secure real-time video chats tailored for small, private groups. Built with **WebRTC**, BlockMeet delivers a seamless conferencing experience.  

### 🔐 Robust Authentication  

We’ve got your back with **JWT**-secured sign-up and sign-in processes. Your identity, your control.  

### 📜 Blockchain Logging  

Every action in your meetings is immutably logged using **smart contracts** written in **Solidity**, deployed on the **Polygon testnet**. Transparency and accountability redefined.  

### 📂 Decentralized File Storage  

Securely store meeting-related files with **IPFS**, integrated via **Pinata**. Share and access files with confidence, knowing they’re safe and decentralized.  

### ⚙️ Hydrocarbon-Inspired Architecture  

BlockMeet’s unique architecture ensures efficient data transfer through a **peer-super peer model**, keeping the experience smooth and private for small groups.  

---

## 🧰 Tech Stack  

We’ve blended the best tools and technologies to build BlockMeet:  

- **Frontend**: React ⚛️  

- **Backend**: Node.js + Express 🌐  

- **Database**: MongoDB 🍃  

- **Video Conferencing**: WebRTC 📹  

- **IPFS Integration**: Pinata 📡  

- **Blockchain**:  

  - Architecture: HardHat 🛠️  

  - Smart Contracts: Solidity 🧾  

  - Deployment: Polygon Testnet ⛓️  

---

## 🏗️ Layered Architecture  

BlockMeet is structured into a clean, modular architecture:  

### 📂 `apps/`  

1. **Client**  

   - Contains the front-end application built with **React**.  

   - Handles the user interface for video conferencing and file storage.  

2. **Server**  

   - The half-brains of the operation, powered by **Node.js** and **Express**.  

   - Manages:  

     - Meeting creation  

     - Adding participants  

     - Handling sign-ups and sign-ins  

3. **WebSocketServer**

   - The other half-Brain

   - This is where the Hydrocarbon stucture is formed 

   - The real-time communication hub for **WebRTC** signaling.  

   - Facilitates the exchange of ISP data and ensures seamless peer-to-peer connections.  

4. **Logging**  

   - Home to **Solidity smart contracts** built with the **HardHat👷🏽**.  

   - Logs meeting events immutably on the **Polygon blockchain**.

## 🌟 How BlockMeet Works  

### 1️⃣ Setting Up a Meeting  

- Define participants before creating a meet.  

- The app calculates **super peers** using the formula:  

  `super_peer_count = ceil(participant_count / 3)`  

### 2️⃣ Joining the Meeting  

- Participants connect in the following order:  

  - The first participant becomes the **first super peer**.  

  - The second participant becomes the **second super peer**.  

  - Subsequent participants connect alternately to super peers in a round-robin manner.  

### 3️⃣ Data Transfer  

- **Super peers** act as relay nodes, transferring video/audio streams between participants.  

- This ensures efficient communication and keeps the architecture simple yet effective.  

### Why This Design?  

- Targeted for **small, private meetings**.  

- Optimized for confidentiality, security, and minimal lag.  

- Perfect for discussions where sensitive information is shared.

## Deployment Deatils

### Deployment 1:

- **Client**: Deployed on **Vercel**.

- **Server**: Deployed on **Vercel**.

- **WebSocketServer**: Deployed on **Render**.

- **Logging**: Deployed on **Polygon Testnet**.

### Deployment 2:

- Tried to deployed on AWS, even deployed the server on Elatic Beanstalk but  then realized that , this will great http based

sites and to access camera I need https

- Then tried to use self signed SSL certificates, but then got to know SSL must have a domain name and other stuff

- Found some ways to do it but it was all for limited period so droped the idea of deploying on AWS for now...

## 🌟 Why Choose BlockMeet?  

- **Decentralized**: Your data is yours alone.  

- **Secure**: Blockchain logging ensures tamper-proof records.  

- **Scalable for Groups**: Designed for small, high-confidentiality meetings.
