Romana, Cebu Institute of Technology-University, Cebu City, Philippines </p> <h6 style="color:black;font-family:classic wide,sans-serif;"><b>ABSTRACT</b></h6> <p style="color:black;text-align:justify;">This research presents a structured framework for migrating the water billing system of the Municipality of Ginatilan, Cebu, from a traditional MySQL-based client-server architecture to a private blockchain environment using Hyperledger Fabric. Motivations for this migration include the need for enhanced security, transparency, and data integrity in public utility management. The framework outlines a step-by-step process involving data modeling, smart contract development, architectural redesign, and system integration. A detailed case study of Ginatilan鈥檚 water billing system demonstrates the practical application of this framework, addressing challenges such as data consistency, performance optimization, and scalability. The research concludes with a comparative analysis evaluating the efficiency, security, and transparency of the blockchain-based system relative to the original MySQL setup. The findings provide actionable insights for other municipalities and public utility providers considering similar modernization efforts through blockchain technology. </p> <h6 style="color:black;font-family:classic wide,sans-serif;"><b>Keywords</b></h6> <p style="color:black;text-align:justify;">MySQL Migration, Hyperledger Fabric, Water Billing System, Private Blockchain, Public Utility Management, Smart Contracts, Data Security and Transparency. </p> <br> <h6 style="color:black;font-family:classic wide,sans-cserif;font-size:20px"><b>Research on the Capacity of Applying Blockchain at High-end Hotels in Vung Tau City </b></h6> <p style="color:black;text-align:justify;font-size: 15px;">MA.
