Blockchain-Based Supply Chain Management Using Hyperledger Fabric

Objective:

To develop a secure, transparent, and tamper-proof supply chain management system using Hyperledger Fabric, enabling all stakeholders to track goods in real-time from origin to destination.

Key Features:

Decentralized Ledger – Immutable records of transactions shared across all participants.

Asset Tracking – Real-time tracking of products from source to end-user.

Smart Contracts (Chaincode) – Automate processes like ownership transfer, quality checks, and payments.

Role-Based Access Control – Only authorized users can access or modify specific data.

Auditability – Full audit trail of every step and change in the supply chain.

Multi-party Collaboration – Manufacturers, suppliers, transporters, and retailers are connected on one platform.

Technologies Used:

Blockchain Platform: Hyperledger Fabric

Smart Contracts: Chaincode written in Go / JavaScript

Frontend: Angular / React.js

Backend: Node.js / Express.js

Database (for off-chain data): CouchDB

Certificate Authority: Hyperledger Fabric CA (for identity management)

Docker & Kubernetes: For containerization and orchestration

REST APIs: For external systems integration

How It Works:

Product Registration:

Each product is registered on the blockchain with a unique ID and metadata.

Transaction Logging:

At every stage (manufacturing, shipping, warehousing, retail), transactions are logged to the blockchain.

Smart Contracts:

Chaincode automates processes like validating documents, temperature logs, and delivery confirmations.

Role-Based Access:

Different stakeholders see only the data relevant to them, using permissioned access.

Tracking Interface:

A dashboard allows stakeholders and even end-users to trace the product journey in real-time.

Benefits:

Transparency: All participants have a consistent view of supply chain data.

Traceability: Easily identify the origin and history of any product.

Fraud Prevention: Immutable records reduce counterfeiting and theft.

Efficiency: Automates manual tasks and speeds up processes.

Accountability: Stakeholders are responsible for their part, reducing disputes.

Security: Data is encrypted and shared only with authorized users.
