ProofPing: Decentralized Proof of Attendance 🎟️

Welcome to ProofPing — a simple yet powerful decentralized Proof of Attendance solution built on the Internet Computer (ICP). ProofPing enables event organizers to securely record and verify participants' attendance on the blockchain.

---

🚀 What is ProofPing?

ProofPing allows event organizers to generate unique event codes, while participants can claim attendance using those codes. All records are stored immutably on the ICP blockchain, ensuring transparency and reliability.

How it Works?

1. Create Event: Generate a unique code for your event.
2. Claim Attendance: Participants enter the code and their name.
3. Verify Attendance: Attendance records are publicly accessible with timestamps.

💡 Why ProofPing?

• Tamper-Proof: Attendance data is permanently stored on the blockchain.
• Simplicity: Minimal setup with one backend function and a lightweight frontend.
• Global Accessibility: Works for online or offline events anywhere in the world.
