This paper explores the integration of IoT and blockchain technologies to advance sustainable agricultural practices through enhanced traceability and efficient carbon sequestration. By deploying IoT for real-time data collection and blockchain for secure, immutable record-keeping, this dual-technology approach addresses key challenges in modern agriculture such as the lack of transparency and traceability, enabling precise monitoring and verification of sustainable practices. The paper details the role of decentralized oracles in bridging real-world data with blockchain networks, ensuring the integrity and accuracy of agricultural data. This integration facilitates dynamic traceability systems that adapt to environmental and market changes, improving decision-making and operational efficiency.
