# 🗳️ P2P Verified Polling App
|
||||
# P2P Poll App
|
||||
|
||||
A decentralized, real-time polling application built with **Nuxt 3**, **Yjs**, and **WebRTC**. This app allows users to create and participate in polls where every vote is cryptographically signed and verified peer-to-peer, ensuring data integrity without a central authority "owning" the results.
|
||||
A peer-to-peer polling application where users can create polls, add options, and vote in real-time without a central server.
|
||||
|
||||
---
|
||||
## Features
|
||||
|
||||
## 🌟 Key Features
|
||||
- **Real-time P2P voting** using WebRTC via PeerJS
|
||||
- **Dynamic option management** - add/remove options during polling
|
||||
- **Duplicate vote prevention** - one vote per user
|
||||
- **Automatic data synchronization** across all connected peers
|
||||
- **Local storage persistence** for poll recovery
|
||||
- **Responsive design** works on desktop and mobile
|
||||
- **No server required** - uses PeerJS free signaling service
|
||||
|
||||
* **Serverless Real-time Sync:** Uses **Yjs** (CRDTs) and **WebRTC** to sync poll data directly between browsers. No database is required for live updates.
|
||||
* **Persistence with Nitro:** While the logic is P2P, the **Nuxt/Nitro** backend provides a "Snapshot" service to ensure polls persist even after all peers go offline.
|
||||
* **Cryptographic Integrity:** Every vote is signed using **RSA-PSS (Web Crypto API)**. Each user has a unique private key (stored locally via `.pem` files) to ensure votes cannot be forged or tampered with.
|
||||
* **Chained Verification:** Implements a "History-Signing" logic where each new vote signs the entire preceding state of the poll, creating a verifiable chain of trust.
|
||||
* **Privacy First:** Users identify via UUIDs and Public/Private key pairs rather than traditional accounts.
|
||||
## How to Use
|
||||
|
||||
---
|
||||
1. **Open the app** in your browser (open `index.html`)
|
||||
2. **First user (Host)**: Leave the Peer ID field empty and click "Connect to Host"
|
||||
3. **Copy your Peer ID** using the "Copy Your Peer ID" button
|
||||
4. **Share your Peer ID** with other users (via chat, email, etc.)
|
||||
5. **Other users**: Paste the host's Peer ID and click "Connect to Host"
|
||||
6. **Create a poll** with question and options
|
||||
7. **Vote** by clicking on options (one vote per person)
|
||||
8. **Watch results** update in real-time across all devices
|
||||
|
||||
## ⚙️ How It Works
|
||||
## Technical Details
|
||||
|
||||
### 1. Identity Creation
|
||||
When a new user is created, the system generates a unique **UUID (User ID)** and an **RSA Key Pair**. The user is prompted to save their **Private Key** as a `.pem` file, named after their User ID (e.g., `550e8400-e29b.pem`). This file acts as their "Passport"—it is never uploaded to the server and must be kept secure by the user.
|
||||
- **P2P Library**: PeerJS (WebRTC-based)
|
||||
- **Frontend**: Vanilla JavaScript with modern CSS
|
||||
- **Data Sync**: Custom conflict resolution for concurrent operations
|
||||
- **Storage**: localStorage for basic persistence
|
||||
- **Network**: Full mesh topology where each peer connects to all others
|
||||
|
||||
### 2. Authentication
|
||||
Upon returning to the app, users load their local `.pem` file. The application extracts the Private Key for signing and the UUID for identification. No passwords or central servers are involved in this local-first login process.
|
||||
## File Structure
|
||||
|
||||
### 3. Joining a Poll
|
||||
When a user joins a poll, the app fetches the latest binary snapshot from the server to populate a local **Y.Doc**. This ensures the user sees the current state immediately, even before connecting to other peers.
|
||||
|
||||
### 4. The P2P Mesh
|
||||
The app establishes connections to other active voters via a WebRTC signaling server. Any changes made to the poll (adding options or voting) are broadcasted instantly to all peers using Conflict-free Replicated Data Types (CRDTs) to prevent sync conflicts.
|
||||
|
||||
### 5. Casting a Signed Vote
|
||||
To ensure security, the voting process follows a strict cryptographic chain:
|
||||
* The app captures the current list of votes.
|
||||
* It appends the new vote data (User ID + Timestamp).
|
||||
* It signs the **entire array** (the previous history + the new vote) using the user's RSA private key.
|
||||
* The signed update is merged into the shared Yjs Map and broadcasted.
|
||||
|
||||
### 6. Distributed Verification
|
||||
Whenever a peer receives a new update, they fetch the voter's **Public Key** from the API. They then verify that the signature matches the current state of the poll history. If a signature is invalid or the history has been tampered with, the vote is rejected by the peer's local state.
