The pharmaceutical supply chain is an organization of interrelated tasks that includes all aspects of the creation, transport, and distribution of medications. The pharmaceutical sector has several challenges to ensure transparency, safety, authenticity, and fraud. Drugs that are counterfeit and traceability are the two most common problems. Blockchain technology can offer remedies like transparency, security, and complete traceability along the whole pharmaceutical supply chain. via joining blocks together using methods of cryptography, a chronological chain comprising data is created through blockchain. Furthermore, it provides a decentralized, immutable ledger for open data and transaction recording. Blockchain technology's primary feature, decentralization, lowers the risk associated with relying on a single point of failure. An Ethereum blockchain-based pharmaceutical supply chain architecture is presented in this article. By automatically enabling and confirming contract agreements, smart contracts allow parties to engage in automated, trustless transactions. The design and development of a web application make use of the React Framework. The Blockchain will be connected to this application, showing every relevant detail about transactions, shipping, and counterfeit medicinal products.
