Abstract: Blockchain technology is transforming the safe sharing and patient data management in a healthcare setting becoming more and more digital. Blockchain's distributed ledger design is challenging conventional centralised systems, often typified by data silos and vulnerability to cyber-attacks. This study offers a complete architecture for blockchain-based health informatics systems guaranteeing data integrity, privacy, and interoperability across many healthcare systems. The suggested system provides a strong solution for automated permission management and safe data exchange by using smart contracts, consensus mechanisms, and cryptographic approaches as well as To effectively manage vast amounts of data while preserving strict security criteria, the architecture combines off-chain storage with on-chain transaction recording. By means of transparent, unchangeable records, and thus build confidence among healthcare professionals, insurance companies, and research organisations, extensive academic analysis and empirical assessments emphasise the potential of blockchain to empower patients. All important for real-time clinical applications, performance benchmarks from pilot tests show gains in transaction throughput, reduced data retrieval latency, and excellent network uptime. Furthermore, the threat modelling and regulatory compliance studies solve important issues around data protection and scalability thus making sure the system fits strict legal frameworks like HIPAA and GDPR. Although perfect integration with legacy systems still presents difficulties, this study highlights the transforming power of blockchain technology in building an interoperable, patient-centric, safe healthcare environment. Future research will concentrate on maximising scalability and improving the regulatory environment to fully exploit blockchain possibilities in health informatics.
