Problem Statement
Traditional presence verification systems are prone to fraud and lack transparency. We need a decentralized, tamper-proof method to prove real-world attendance securely.
🚀 Project Overview
Proof of Presence is a decentralized application (dApp) designed to verify and record the presence of individuals at a specific location or event using blockchain technology. It ensures transparency, immutability, and trust, making it useful for events, conferences, meetups, or even secure facility check-ins.
🛠 Tech Stack
Smart Contracts: Solidity (Ethereum-compatible blockchain - XDC Network)
- Backend: Node.js, Express.js
- Blockchain Interaction: Web3.js
- Wallet Extension : BlocksPay
🧩 Features
- Register and track user presence at events.
- Smart contract-based proof ensuring tamper-proof presence logs.
