This paper explores the integration of blockchain technology, smart contracts, RSA-Encrypted NFTs, and IPFS to address transparency and ethical sourcing challenges in the supply chains of organic products. Through a detailed examination and testing of the proposed system on various Ethereum Virtual Machine (EVM)-compatible platforms, the study evaluates the system’s effectiveness in enhancing traceability, operational efficiency, and ethical compliance from production to end consumer. Incorporating insights from existing literature, the research underscores the potential of these technologies to fortify supply chain management by providing accurate, secure, and verifiable data. The findings demonstrate that such an integrated approach can significantly elevate the transparency, trustworthiness, and accountability of organic product supply chains, offering a scalable and economically feasible solution to longstanding industry challenges.
