+# Fact Verifier Extension
+
+A browser extension that verifies facts and news claims using the Cortensor decentralized inference network.  
+It checks statements against multiple independent nodes, aggregates results, and returns a consensus-backed verdict with citations.
+
+## Features
+- ✅ Consensus-based truth checking (multiple nodes verify claims)
+- 📊 Confidence score (% agreement across nodes)
+- 🔗 Source citations for transparency
+- 🌐 Easy-to-use browser extension (highlight → verify → result)
+
+## How It Uses Cortensor
+This project integrates with the **Cortensor Decentralized Inference API**.  
+Each verification request is processed by multiple nodes, and their responses are aggregated to ensure reliability and reduce hallucinations.
+
+## Installation (Dev Mode)
+1. Clone this repo.
+2. Navigate to `apps/fact-verifier-extension/`.
+3. Load the extension in Chrome/Brave via `chrome://extensions` → **Load unpacked**.
+4. Select the extension folder.
+
+## Roadmap
+- [ ] Backend middleware to call Cortensor API
+- [ ] Consensus logic (aggregate responses)
+- [ ] Browser extension UI
+- [ ] Confidence scoring + citations
+- [ ] (Optional) On-chain notarization of results
