A Blockchain-Based Traceability System for Agricultural Supply Chains

CHAPTER 1: INTRODUCTION

Background of the Study

Agricultural supply chains are increasingly required to demonstrate transparency, traceability, and compliance with international standards. However, many systems still rely on manual documentation, making them vulnerable to fraud, inefficiency, and data loss.

Blockchain technology introduces a decentralized and immutable ledger that can secure records and ensure trust among stakeholders. Integrating this with QR code authentication and real-time data capture enables a new level of transparency from farm to market.

AgriTrace™ is proposed as a blockchain-enabled traceability platform designed to record, verify, and authenticate agricultural products throughout their lifecycle.

Statement of the Problem

This study seeks to address:

Lack of reliable traceability systems
Product fraud and mislabeling
Inefficient compliance documentation
Limited access to premium markets
Lack of integrated digital platforms

Objectives of the Study

General Objective

To develop a blockchain-based traceability system.

Specific Objectives

Develop farm registration module
Implement field data capture
Create batch tracking system
Integrate blockchain verification
Develop QR authentication system

Significance of the Study

Farmers: improved market access
Exporters: verified supply chains
Consumers: increased trust

Scope and Limitations

Scope includes prototype development; limitations include limited deployment scale.

CHAPTER 2: REVIEW OF RELATED LITERATURE
