A Growing but Uncounted Market
There is no single authoritative global registry that tracks every blockchain medical records company, but market research and competitive landscape reports consistently identify 50 to 100+ dedicated platforms worldwide — plus major IT incumbents that have added blockchain-based health record products to their portfolios. The ecosystem is expanding rapidly, making any fixed number outdated within months.
Market Size and Growth
Two parallel sets of market estimates frame the scale of this sector:
Key Players by Category
Market reports segment participants into three broad groups:
| Company | Category | Primary Focus |
|---|---|---|
| IBM Corporation | Big Tech Incumbent | Enterprise EHR on Hyperledger Fabric |
| Oracle / Microsoft Azure | Big Tech Incumbent | Cloud-based blockchain health infrastructure |
| Guardtime | National Infrastructure | KSI blockchain; Estonia & UAE national health systems |
| Avaneer Health | Payer/Provider Network | Backed by CVS, Aetna & Cleveland Clinic; Hyperledger Fabric |
| BurstIQ | Patient Data Marketplace | HIPAA-compliant health data exchange & research |
| Patientory | Patient-Centric Platform | Connects patients, providers, and payers |
| Medicalchain | Single Source of Truth | UK-based; unified patient record integrity |
| Solve.Care | Care Coordination | Decentralized care management & billing |
| Hashed Health | Decentralized Platform | Interoperable customizable healthcare solutions |
| Chronicled | Pharma / Supply Chain | Drug traceability and serialization |
| Embleema | Clinical Research | Patient-reported outcomes for clinical trials |
| Change Healthcare | Claims & Billing | Acquired PokitDok; billing automation |
Notable Real-World Deployments
Guardtime is the most advanced example of national-scale deployment: its KSI (Keyless Signature Infrastructure) blockchain underpins Estonia's entire national health system and was also deployed for a major private healthcare provider in the United Arab Emirates, covering secure EHR exchange, vaccine tracking, and patient consent management.
Avaneer Health, backed by CVS Health, Aetna, and Cleveland Clinic, runs a real-time secure data exchange platform for payers and providers, handling billing, prior authorizations, and provider directory management — all built on Hyperledger Fabric.
In March 2025, Circular Protocol partnered with Arculus by CompoSecure and IT Lab to launch Smart Share, a white-label blockchain platform for on-chain verification and authentication of medical records, integrating a MedTech device with blockchain infrastructure.
Geographic Distribution
Investment and deployment activity is concentrated in North America (largest market, driven by HIPAA compliance pressure and the scale of U.S. healthcare spending) and Europe (GDPR compliance demand, national health system pilots in Estonia, UAE, and the UK). Asia-Pacific players are gaining traction through public-private partnerships and government-led digital health initiatives. Emerging markets in Africa, Latin America, and Southeast Asia represent the next frontier, as blockchain offers a cost-effective alternative to expensive legacy EHR buildouts.
What Is Driving Growth?
Several structural forces are accelerating adoption. In 2023 alone, data breach costs for U.S. healthcare organizations reached a record $7.13 million per incident — a 10% year-on-year increase. More than 40% of breaches involved unauthorized access to patient information. At the same time, regulatory pressure from HIPAA (U.S.) and GDPR (EU) is pushing organizations toward tamper-resistant, auditable record systems. Blockchain addresses both imperatives simultaneously: it provides immutable logging of every data access event while enabling patient-controlled consent and cross-institutional interoperability — the two biggest shortcomings of centralized EHR platforms.
Bottom Line
Conservatively, 50–100+ companies globally are actively offering blockchain-based medical records control and management, spanning dedicated startups, large IT vendors, and regional players. The market is valued at over $1 billion in 2025 and is projected to reach $11 billion in the broader healthcare blockchain segment by 2029. Rather than citing a fixed number — which becomes outdated quickly — the most accurate framing is: dozens of dedicated platforms plus major incumbents, with new entrants appearing monthly.
