Abstract: The growing complexities involved in the global supply chain system have brought about greater problems relating to data integrity, transparency, and trust issues. Traditional centralized systems of supply chain management are vulnerable to single point failure, lack of traceability, and fraudulent activities. This paper proposes a secure and transparent supply chain management system based on blockchain technology, utilizing smart contracts and cryptographic techniques to overcome these weaknesses. The proposed framework is a combination of IoT-based data ingestion with a blockchain network, using optimal queuing technique for efficient transaction processing. The simulation results reveal considerable gains in terms of trace-back capability (decrease from 95 seconds to 8 seconds), transactional efficiency (120 transactions per minute), and data integrity (99.9% fraud detection capability). Comparison with the traditional framework reveals a 14-times gain in dispute resolution and 70% improvement in trust indicators,
