-# P2P Poll App
+# 🗳️ P2P Verified Polling App
 
-A peer-to-peer polling app built with [Automerge](https://automerge.org/) and Vanilla JS. No backend required — polls sync in real time across browsers using CRDTs and a WebSocket relay.
+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.
 
-## Features
+---
 
-- **Add options** — type an option and press Enter or click "Add Option". Duplicate options (case-insensitive) are rejected with an inline error message.
-- **Vote on options** — click the vote button next to any option. You can vote on multiple options, but only once per option.
-- **Toggle votes** — click your vote again to remove it (the button turns green with a checkmark when you've voted).
-- **Live vote counts** — options are sorted by vote count in descending order and update in real time as votes come in from other users.
-- **2-minute countdown timer** — click "Start 2-min Vote" to begin a shared countdown. Voting is open before and during the countdown. Once the timer expires, all vote buttons are disabled.
-- **Shared timer** — the deadline is stored in the Automerge document, so all peers see the same countdown and voting closes simultaneously for everyone.
-- **Copy URL** — click "Copy URL" to copy the poll link to your clipboard. Share it with others to join the same poll.
-- **P2P sync** — all state (options, votes, timer) syncs across browsers in real time with no central server handling your data.
+## 🌟 Key Features
 
-## How it works
+* **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.
 
-### Tech stack
+---
 
-- **[Automerge](https://automerge.org/)** via `@automerge/vanillajs` — a CRDT library that lets multiple clients concurrently edit shared documents and merge changes without conflicts.
-- **BroadcastChannelNetworkAdapter** — syncs between tabs in the same browser instantly via the browser's BroadcastChannel API.
-- **WebSocketClientAdapter** — syncs across different browsers/devices via a WebSocket relay (`wss://sync.automerge.org`). The relay only forwards CRDT messages; it does not store or interpret your data.
-- **IndexedDBStorageAdapter** — persists the document locally so it survives page refreshes.
-- **Vite** — bundles the app with WebAssembly support (required by Automerge).
+## ⚙️ How It Works
 
-### Data model
+### 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.
 
-The poll is a single Automerge document with three fields:
+### 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.
 
-```js
-{
-  options: string[],       // list of poll options in insertion order
-  votes: { [option]: number }, // vote count per option
-  deadline: number | null  // Unix timestamp (ms) when voting closes, or null
-}
-```
+### 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.
 
-### URL-based sharing
+### 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.
 
-Each document gets a unique Automerge URL (e.g. `automerge:abc123...`) stored in the page's URL hash. Opening the same URL in any browser loads and syncs the same document. Creating a new poll generates a new document and updates the hash automatically.
+### 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.
 
-### Voting rules
+### 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.
 
-- Voted options are tracked in `localStorage` (keyed by document URL), so they persist across page refreshes but are isolated per browser.
-- One vote per option per user. Votes can be toggled off and back on until the timer expires.
-- The timer (`doc.deadline`) is set once by whoever clicks "Start 2-min Vote" and is shared via the Automerge document, so all peers use the same deadline.

+# AI Disclaimer
+
+This App was developed with the assistance of AI.
+
+# Nuxt Minimal Starter
+
+Look at the [Nuxt documentation](https://nuxt.com/docs/getting-started/introduction) to learn more.
+
+## Setup
+
+Make sure to install dependencies:
 
 ```bash
+# npm
+npm install
+
+# pnpm
 pnpm install
-pnpm dev
+
+# yarn
+yarn install
+
+# bun
+bun install
 ```
 
-Open the printed localhost URL. To test cross-browser sync, copy the URL (including the `#automerge:...` hash) and open it in a different browser.
+## Development Server
+
+Start the development server on `http://localhost:3000`:
+
+```bash
+# npm
+npm run dev
+
+# pnpm
+pnpm dev
+
+# yarn
+yarn dev
+
+# bun
+bun run dev
+```
+
+## Production
