Veritime: Enhancing Service Industry Accountability with Smart Contracts and IoT Integration

Abstract

In fast-moving business environments, timely and reliable service delivery is required, although the traditional methods of verification are seldom accountable and transparent. Veritime addresses these issues through an automated verification system based on blockchain, smart contracts, and IoT sensors. It enables secure delivery verification, automated payment upon successful delivery, and real-time tracking of shipment by using cryptographic passphrases from Ethereum contracts and IoT-enabled containers. The key elements in Veritime involve the sender, receiver, blockchain network, IoT sensors, and the MQTT server. Developed in Python, Veritime topped the benchmark for performance and delay in power efficiency and packet delivery compared to traditional systems. Gas cost analysis showed that functions like “Register Manufacturer” and “Assign Distributor” consume 47,335 and 56,789 transaction gas, confirming the efficiency and reliability of the system.
