Medi-Chain: Blockchain Based Framework for Drug Tracking and Authentication System

Abstract

Medi Chain is a system that is established to introduce a higher degree of trust and transparency into the process of medicine supply. In the current times, counterfeit and bootleg drugs are a point of serious concern, particularly in cases where the physician prescribes them. Medicine batches are tracked and recorded by Medi Chain via blockchain since the stage of manufacture to the point of sale. The data stored is unchangeable and unbreachable as all the data is stored on the Sepolia Ethereum network in the form of smart contracts. Through QR- based checks, the platform enables users of the site to scan a code and instantly access essential information, including the source of the medication, who touched it, and the presence of a valid prescription pivotal to that prescription. This has made the system easy to use as the blockchain logic is written in Solidity and Web3.js, and the user interface is written in React.js and Tailwind CSS. Firebase is used to deal with secure log in, document uploading, and storage of prescription files. The system includes some basic yet significant precautions to ensure that the process of medicine handling happens safely in all stages. Each medicine flow remains exposed and safe and cannot be abused or misused. MetaMask logins, quick scans on QR, allow its users to quickly verify authenticity, making sure that prescriptions are adhered to.
