What Blockchain for Health Data Interoperability & Patient-Controlled Records (2026) requires
Blockchain and distributed ledger technologies enable secure, patient-controlled health records with verifiable provenance, immutable audit trails, and selective disclosure. Governance must address data privacy (off-chain sensitive data), regulatory compliance, interoperability with FHIR, consent management on-chain, and legal recognition of blockchain records. Hybrid on/off-chain architectures are standard.
