This study introduces a novel framework leveraging Zero Knowledge (ZK)-Rollups-enhanced Layer 2 blockchain and Non-Fungible Tokens (NFTs) to address these issues. NFTs serve as secure digital certificates for individual cattle health records, ensuring transparency and traceability. ZK-Rollups on the Layer 2 blockchain enhance scalability, privacy, and cost-efficiency, while smart contracts automate key processes such as veterinary scheduling, medication delivery, and insurance claims, minimizing administrative overhead. Performance evaluations reveal significant advancements, with transaction delays of 4.1 ms, throughput of 249.8 TPS, gas costs reduced to 26,499.76 Gwei, and a time-to-finality of 1.1 ms, achieved through ZK-SNARKs (ZK-Succinct Non-Interactive Arguments of Knowledge) integration. These results demonstrate the system\u2019s potential to revolutionize cattle healthcare management by combining transparency, security, and operational efficiency.<\/jats:p>","DOI":"10.3390\/systems13010065","type":"journal-article","created":{"date-parts":[[2025,1,20]],"date-time":"2025-01-20T12:32:52Z","timestamp":1737376372000},"page":"65","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Integrated Dairy Production and Cattle Healthcare Management Using Blockchain NFTs and Smart Contracts"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9517-9792","authenticated-orcid":false,"given":"Saravanan","family":"Krishnan","sequence":"first","affiliation":[{"name":"Department of CSE, College of Engineering Guindy, Anna University, Chennai 600025, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lakshmi Prabha","family":"Ganesan","sequence":"additional","affiliation":[{"name":"Department of CSE, College of Engineering Guindy, Anna University, Chennai 600025, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,20]]},"reference":[{"key":"ref_1","unstructured":"Global Dairy Industry (2024, December 03).
