Blockchain-Enabled Trade Finance Framework for Secure Drug Supply Chain Transactions

The pharmaceutical supply chain is a network of various stakeholders such as manufacturers, distributors, logistics providers, pharmacies, and regulatory authorities. It is essential to ensure transparency, security, and trust among them to prevent counterfeit drugs, data manipulation, and financial fraud. Drug supply chains using traditional trade finance processes are heavily dependent on paper, based documentation and centralized systems. These practices often cause delays, result in high transaction costs, and reduce traceability. This article introduces a Trade Finance Framework Powered by Blockchain for enhancing security in the drug supply chain transactions. The framework utilizes blockchain technology to offer decentralized, tamper, proof record keeping and real, time transaction verification. Smart contracts facilitate the automation of trade finance procedures such as letter of credit validation, payment release, and compliance verification, thus cutting down on processing time and human intervention. A distributed ledger keeps a record of each transaction, which is accessible to all and cannot be altered, all while hiding the sensitive data through encrypting mechanisms. The system put forward bolsters the mutual trust of the different parties involved, increases the ability to trace pharmaceutical products, decreases the risks of fraud, and makes regulatory compliance easier. The framework, by combining blockchain with trade finance, enables secure, effective, and transparent drug supply chain management, thus leading to higher patient safety and better financial accountability.
