Blockchain-Based Framework for Transparent, Immulate and Secure Vaccine Supply Chains

Abstract

This project uses blockchain technology to make the pharmaceutical supply chain safer and more transparent. It helps stop counterfeit (fake) drugs by recording every step — from raw materials to the patient — in a secure, unchangeable way. Today’s supply chains have many problems like lack of information sharing, complex processes, and too much central control, which makes it easier for fake drugs to enter the market. According to the World Health Organization, fake medicines cause many deaths, especially among children, and cost the industry a lot of money.

Our solution uses smart contracts to track and verify each step of the drug’s journey. We designed a system with detailed architecture, diagrams, and algorithms to show how it works. Testing shows that our blockchain system is secure, easy to scale, and can be used in different pharmaceutical supply chains to ensure drug authenticity and safety.
