With a secure distributed ledger system, blockchain technology helps to
shape the healthcare sector in terms of transparency and accountability. This research
paper highlights the transformational impact that blockchain technology plays in the
healthcare sector. It focuses on a variety of technologies, including patient data
security, real-time monitoring enabled Internet of Things (IoTs). This paper also
addresses the revolutionary impact that current technology, such as cryptography and
Zero Knowledge Proofs (ZKPs), has played in shaping modern technology and
improving privacy and security in the health care system. This study contrasts existing
blockchain technologies with emergent developments that aid in the creation of a
decentralized, safe ecosystem that promotes accountability. Blockchain provides a
decentralized, immutable, and transparent ledger. It enhances security, privacy, and
trust in data transactions without relying on centralized servers.
Keywords: Blockchain, Cryptography, Zero Knowledge Proofs (ZKPs), Internet of Things (IoT), Decentralized Ledger, Data Privacy, Smart Contracts, Electronic Health Record.
