Healthcare Blockchain

Healthcare blockchain creates immutable, distributed records of medical data. Unlike centralized databases, blockchain stores records across a network of healthcare providers. Each transaction (patient consent, medication, test result) is cryptographically signed and cannot be altered retroactively. Healthcare blockchain has three main use cases: (1) patient records and HIE (health information exchange), (2) supply chain (drug traceability), and (3) clinical trials (consent and data integrity).
