🔒 Blockchain for Secure Health Data Sharing: Trust, Privacy & The Future of Care Signature portrait composite/co-created: Rima, 47, a nurse and mother, moves between two hospitals and a community clinic. Her records are fragmented, permissions opaque, and sometimes her test results “vanish” between systems.
