This paper explores the integration of blockchain technology, smart contracts, encrypted Non-Fungible Tokens (NFTs), and the InterPlanetary File System (IPFS) in enhancing the management of animal health data. Facing challenges such as the lack of traceability and the need for data security within the veterinary sector, our study proposes a novel approach that leverages advanced encryption algorithms-RSA, RC4, DES, ChaCha20, Blowfish, and AES-to ensure the confidentiality and integrity of health records. By conducting a comprehensive analysis of various EVM-compatible blockchain platforms, including Binance Smart Chain, Polygon, Fantom, and Celo, we assess the system’s performance, operational efficiency, and economic feasibility. Our findings highlight the potential of our proposed framework to significantly improve transparency, reliability, and accessibility in the management of animal health data, providing a solid foundation for ethical practices and informed decision-making in veterinary care.
