Abstract
The convergence of blockchain, IoT, and cloud technologies has created new opportunities for secure, transparent, and autonomous data management in smart manufacturing systems. In this study, we developed a Cloud-Blockchain Integrated Fermentation Device (CBIFD) that enables real-time monitoring and distributed logging of environmental data during fermentation. The system employs a modular sensor configuration to measure pressure, temperature, humidity, internal temperature, CO(2), and pH, and is integrated with an Arduino Nano 33 IoT. Its cloud-native, self-contained architecture eliminates the need for a local server, ensuring high mobility and scalability. System performance was validated in a laboratory setting, demonstrating seamless data acquisition, reliable cloud synchronization, and consistent execution of blockchain transactions. Moreover, comparative analysis with existing IoT-blockchain architectures highlights the superior autonomy and infrastructure flexibility of the CBIFD. This work provides a robust foundation for future research aimed at enhancing process transparency and data-driven control in intelligent fermentation environments.
