Global trade liberalization, supply chains are facing more challenges in terms of trust, supply chain transparency, and operational effectiveness. This research investigates the interdependence between big data analytics and blockchain technology to create robust, transparent, and information-led supply networks. Blockchain's shared ledger guarantees an untameable record of transactions, which allows real-time visibility and the reduction of opportunities for fraud or data manipulation. Besides, predictive analytics and machine learning algorithms use historical and real-time data to aid in inventory optimization, demand planning, and risk management policies. The envisioned framework signifies how blockchain and data science integration enhances the resilience of supply chains, enhances decision correctness, and builds stakeholder confidence. In addition, the study discusses the level to which smart contracts might automate regulatory compliance and trigger dynamic operational adjustments, thus minimizing manual interventions and human errors. It further elaborates on the manner in which the integration of Internet of Things (IoT) sensors can allow for improved timeliness and fidelity of data, which further improves analytical outcomes. By mass simulation-based testing and comparative examination against common centralized supply chain management systems, this research verifies the efficacy of this integrated approach in shifting contemporary supply chain management into a secure, effective, and future-proof ecosystem. The outcomes indicate that blockchain and high-end analytics not only mitigate threats of counterfeiting and delay, but also maintain drives for sustainability by enabling transparent tracking of the environmental footprint across supply chains. Finally, suggestions for mass deployment and potential future research avenues in edge AI as well as federated learning are suggested to ensure continuous innovation and responsiveness in global supply chains
