Blockchain Development for Healthcare
Patient Records, Clinical Trials, and Supply Chain Integrity — We have built healthcare data systems on blockchain since 2014. 1,000+ blockchain projects. We build HIPAA-aware permissioned blockchain infrastructure that gives authorized healthcare providers access to verified patient data — without the single-point-of-failure risk of a centralized health data repository.

Executive Answer
Key information at a glance
US healthcare data breaches cost an average of $10.9 million per incident in 2023 — the highest of any industry for the 13th consecutive year, according to IBM's Cost of a Data Breach Report. The problem is architecture: centralized health data repositories are single targets. A blockchain-based health data infrastructure distributes the risk, gives patients control of their own records, and provides every authorized provider with a verified, up-to-date record without requiring a central custodian.
Healthcare Blockchain Use Cases
Patient Health Record Sharing
A permissioned blockchain where patients control which providers can access their records. Providers query the blockchain for a patient's authorized record index, retrieve records from the corresponding encrypted storage, and write new records back with the patient's consent. No central repository holds all records — reducing the breach surface area dramatically. HIPAA compliance is maintained by storing PHI in encrypted off-chain storage, with only hashes and access permissions on-chain.
Clinical Trial Data Integrity
Clinical trial data recorded on blockchain before analysis eliminates the possibility of post-hoc data manipulation — a documented problem in pharmaceutical research. Immutable timestamps prove that the protocol was not modified after observing interim results. FDA 21 CFR Part 11 requirements for electronic records are met by the blockchain's immutable audit trail.
Pharmaceutical Supply Chain (DSCSA)
Drug Supply Chain Security Act compliance requires track-and-trace of every prescription drug package.
Healthcare Claims Automation
Insurance claims for routine, verifiable healthcare events (lab results above/below threshold, diagnostic codes confirming covered conditions) can be processed by smart contracts without manual adjudication — reducing the 40% administrative overhead cost of US healthcare claims processing.
Case Study: Multi-Hospital Patient Record Network — Consent-Controlled Access
The challenge: A US hospital network needed to allow any of their 8 member hospitals to access a patient's records from any other member hospital — while giving patients control over which hospitals could access their data and providing a complete audit trail of every access event.
What we built: A Hyperledger Fabric network with one node per hospital. Patient consent records on-chain (which hospitals have read access to which record types). PHI stored in encrypted FHIR-format storage, decryptable only by nodes with the patient's consent token. Every access event recorded on-chain with timestamp and accessor identity.
Results: Patient consent management: 100% on-chain. Access audit trail: complete, immutable. Cross-hospital record retrieval time: 2.3 seconds average. HIPAA audit preparation time: reduced by 55%.

Frequently Asked Questions
Important Questions Before You Build
Clear answers to common strategic, technical and implementation questions related to this industry.
PHI should not be stored on a blockchain — it is impossible to delete, which conflicts with HIPAA's right-to-access and correction requirements. The correct architecture stores PHI in encrypted off-chain storage (under the covered entity's control) and stores only hashes, access permissions, and audit events on-chain. This provides blockchain's immutability and auditability benefits without storing PHI in an un-deletable record.
Blockchain is a technology, not a system. A blockchain-based system can be designed to comply with HIPAA when PHI handling follows HIPAA's technical safeguard requirements. Our designs keep PHI off-chain and use the blockchain only for consent management, access control, and audit trails — all of which are appropriate for on-chain storage.
