Blockchain technology is driving a major transformation in the healthcare industry by providing a secure and decentralized framework for managing sensitive medical records. Unlike conventional systems that rely on centralized databases--often vulnerable to cyber-attacks and unauthorized alterations--blockchain operates on a distributed ledger where recorded data is immutable. This immutability significantly enhances data integrity and reduces the risk of security breaches. A key strength of blockchain in healthcare is its ability to ensure privacy. Through encryption and decentralized control, access to medical information is restricted to authorized users only. Additionally, blockchain enables efficient and secure data sharing among hospitals, clinics, and specialists, overcoming challenges posed by fragmented or inconsistent health records. This improves the speed and accuracy of patient care. Smart contracts further enhance the system by automating access permissions and updates based on predefined rules. These self-executing protocols minimize manual intervention, reduce administrative overhead, and lower the chance of human error. Most importantly, blockchain empowers patients by giving them full control over their personal health data. Patients can choose who accesses their records, fostering transparency and trust between healthcare providers and individuals. This patient-centric approach encourages active participation in healthcare decisions and supports a more collaborative care environment.
