Abstract: Healthcare systems around the world are at a critical juncture, navigating the pressures of digital transformation, rising cybersecurity threats, and fragmented data landscapes. While the volume of healthcare data grows exponentially, the capacity to manage it securely and effectively across stakeholders remains limited. Blockchain, a decentralized ledger technology known for transparency and immutability, is emerging as a viable framework for improving data integrity, patient control, and system interoperability. This whitepaper explores blockchain as a promising, decentralized solution to redefine the digital infrastructure of healthcare. This paper discusses current challenges, the mechanics of blockchain, real-world applications, and future directions.
1. Introduction
In today’s digitized world, the healthcare sector is inundated with data: electronic health records (EHRs), diagnostic results, insurance claims, and wearable device outputs. Yet, this data is often siloed, poorly secured, and inaccessible to both patients and providers. A lack of interoperability leads to redundant tests, delayed diagnoses, and increased healthcare costs.
