If a critical component is found to be defective, requiring a recall, how does the blockchain's data provenance feature specifically facilitate the recall process, beyond simply identifying the defective batch?

Question 4

A global pharmaceutical company is implementing a blockchain to track the cold chain integrity of sensitive vaccines. They need to ensure that temperature data from IoT sensors is accurately and securely recorded on the blockchain to trigger automated alerts if thresholds are breached. What is the most significant technical challenge in integrating these real-world IoT sensor data streams with the blockchain's smart contract logic?

Question 5

In a blockchain-based supply chain finance system, a smart contract is designed to release payment to a supplier only after a shipment's proof of delivery is confirmed by the buyer.
