Course overview
Lesson Overview
6.19 – Supply Chain Transparency via Blockchain: Blockchain brings visibility to every step of global supply chains by recording product movements in real time.

Companies and consumers can trace goods from origin to shelf with full accountability. Supply-chain transparency enhances efficiency, sustainability, and consumer trust, proving blockchain’s real-world value beyond finance.
