Real-Time Monitoring and Transparency in Pizza Production Using IoT and Blockchain

2025-07-03

AI Summary

To address challenges in pizza production—including inadequate food safety supervision, untrustworthy data, and inefficient traceability—this paper proposes a real-time, trustworthy monitoring system integrating IoT and blockchain. The system employs Raspberry Pi–based edge nodes equipped with temperature-humidity sensors and cameras to capture environmental parameters and critical-process imagery. Collected data are hashed and immutably recorded on-chain, while smart contracts automatically trigger responses (e.g., anomaly alerts, batch freezing) to ensure end-to-end auditability and tamper resistance. Experiments demonstrate that the solution reduces ingredient traceability time to seconds, decreases spoilage from temperature excursions by ~23%, and enables real-time regulatory compliance verification. Its core innovation lies in a lightweight edge–blockchain co-design architecture that jointly optimizes real-time responsiveness and cryptographic trustworthiness, establishing a practical digital trust paradigm for small- and medium-scale foodservice operations.

Abstract

This paper presents a blockchain-based Internet of Things (IoT) system for monitoring pizza production in restaurants. IoT devices track temperature and humidity in real-time, while blockchain ensures secure and tamper-proof data. A Raspberry Pi processes sensor data, captures images, triggers alerts, and interacts with smart contracts. The system detects abnormal conditions, enabling quick responses. Blockchain adds transparency and traceability, supporting compliance and audits. Experiments show improved ingredient management, reduced waste, and increased kitchen efficiency.
