Abstract: ABSTRACT BLOCKCHAIN-BASED PHARMACEUTICAL DRUG SUPPLY CHAIN TRACEABILITY SYSTEM WITH IoT COLD CHAIN VERIFICATION The Present Invention Relates to an blockchain-based pharmaceutical drug supply chain traceability system (100) comprising a permissioned blockchain network (110) with supply chain nodes at manufacturer (142), distributor (144), cold storage facility (146), and pharmacy (148). An IoT sensor integration module (120) with temperature sensor (122) and humidity sensor (124) appends aggregated sensor data to each custody transfer ledger entry as a cold chain integrity attestation. A smart contract engine (130) with a custody transfer smart contract (132) records transfer events and a cold chain alert smart contract (134) evaluates appended sensor data against predefined thresholds, triggering alerts upon cold chain excursions. A drug provenance verification interface (150) enables batch history retrieval. A regulatory audit access module (160) provides read-only ledger access for compliance audit. [
