ChainTrace

A blockchain-based supply chain traceability platform leveraging decentralized storage, IoT data integration, and zero-knowledge proofs.

Overview

ChainTrace is designed to provide transparent, secure, and verifiable supply chain tracking from production to consumption. The platform enables manufacturers, logistics providers, retailers, and consumers to participate in a decentralized supply chain ecosystem.

Key Features

• Blockchain-based Traceability: Complete product lifecycle tracking on-chain
• IoT Integration: Real-time sensor data collection and verification
• Zero-Knowledge Proofs: Privacy-preserving data verification
• Decentralized Storage: IPFS integration for scalable data storage
• Multi-party Collaboration: DID-based identity management and access control
• API & SDK: Standardized interfaces for enterprise integration

Architecture

Core Components

1. Smart Contracts: TraceRegistry, ProofVerifier, AccessControl, AuditLog
2. Frontend: React-based web application for supply chain visualization
3. Backend: Node.js API server with blockchain integration
4. IoT Module: Edge computing nodes for sensor data processing
5. Storage Layer: IPFS for decentralized data storage

Technology Stack

• Blockchain: Hyperledger Fabric / Polygon / Arbitrum
• Frontend: React, TypeScript, Web3.js
• Backend: Node.js, Express, TypeScript
• Database: PostgreSQL, Redis
• Storage: IPFS
• Cryptography: zk-SNARKs, Post-quantum cryptography

Development Phases
