Towards a Milk Quality Recording and Monitoring System Based on Blockchain and Long-Range Internet of Things

The milk production chain in Brazil requires continuous monitoring of physicochemical parameters to ensure quality and prevent adulterations. We present a decentralized system based on IoT, long-range networks, and blockchain, enabling traceability from the beginning of production. Implemented in rural areas without internet access, this solution ensures transparent and secure quality control. The proof of concept demonstrates technical feasibility, serving as a crucial foundation for future testing and advancements in the field. In summary, our system provides effective traceability in milk production, maintaining rigorous quality control and auditability.
