A Blockchain-Based Framework for Managing Electronic Health Records of Farm Animals

Abstract

The transition from paper-based to digital records has significantly enhanced healthcare practices, including the management of farm animal health.Electronic Health Records (EHRs), referred to as Animal Medical Records (AMRs), are essential for improving clinical workflows, supporting evidence-based decisions, and advancing veterinary research.However, the adoption of digital records introduces challenges related to data security, quality, and interoperability.This paper explores the use of blockchain technology to address these challenges.We propose a blockchain-based system for managing AMRs that leverages Non-Fungible Tokens (NFTs) and smart contracts to ensure data integrity, transparency, and accessibility.The system is evaluated through a proof-of-concept deployment on four EVM-supported platforms: BNB Smart Chain, Celo, Fantom, and Polygon.Our findings indicate that blockchain technology can enhance the security and efficiency of managing electronic health records for farm animals.
