TL;DR
This paper introduces a framework to convert traditional EMR systems into blockchain-based systems, ensuring data integrity and compliance while maintaining performance.
Contribution
A hybrid framework that combines MySQL and Hyperledger Fabric for EMR systems, enabling tamper-proof logging with minimal performance loss.
Findings
The hybrid system sustains near-native responsiveness with a median latency of 2.1 ms.
It achieves 480 TPS with modest CPU and RAM overhead.
The framework enhances data integrity and compliance with regulations like Oman’s PDPL.
Abstract
Electronic Medical Records (EMRs) are crucial to modern healthcare. However, traditional relational databases fail to fulfill increased expectations for integrity, auditability, and compliance in regulated environments. This paper proposes a Hybrid Blockchain Migration Framework that integrates a conventional MySQL-based EMR system (OpenMRS) with a permissioned blockchain network (Hyperledger Fabric). Sensitive data fields are selectively mirrored to the blockchain, ensuring tamper-evident logging while retaining the high performance of SQL for routine operations. A middleware layer, implemented using Java Spring Boot, monitors changes in the EMR and commits cryptographic hashes and metadata to the blockchain in near real-time. We evaluate the hybrid system against both standalone MySQL and full-blockchain implementations using controlled benchmarks, analyzing latency, throughput,…
