BlockTrack Supply Chain Verification Protocol (V2.0)

Trustless transparency for real-world products.

📖 Overview

BlockTrack is a dual-layer anti-counterfeit protocol combining physical seals with cryptographic verification. Standard QR codes can be copied. BlockTrack cannot.

Why It Exists

🔴 The Problem	🟢 The Solution: Dual-Key Identity
QR codes are easily cloned.	Each product receives two keys:
Copy genuine code → paste on fake product → system fails.	1. Public ID (Printed on packaging) 2. Private Key (Hidden under scratch-off seal)
Consumers can't verify authenticity.	Trust the math, not the manufacturer.

🔐 Security Model

1. Physical Lock: Private Key protected by a scratch-off layer.
2. Digital Lock: Once the Private Key is claimed, the product becomes CONSUMED on-chain.
3. Counterfeit Trap: Any re-scan of a consumed ID triggers a 🔴 "Product Has Been Claimed Before" warning.

🚀 System Flow

1. Minting: Manufacturer mints asset → Gets Public QR + Sealed Private Key.
2. Logistics: Simulation of flow (Factory → Truck → Pharmacy).
3. Verify (Consumer): Scans Public ID → Sees VERIFIED + Supply chain timeline.
4. Claim (Consumer): Scratches seal & enters Private Key → Backend verifies → Status = CONSUMED.
5. Trap: Re-scanning this ID now triggers a red counterfeit warning.
