Your Data is Secure, But is it Shareable?
The healthcare industry runs on data, but that data is trapped. Siloed in legacy EMRs, vulnerable to breaches, and difficult to share for critical research, it creates friction that costs time, money, and potentially lives. Traditional data sharing methods are slow, require complex point-to-point integrations, and fail to provide a single source of truth for patient consent and data provenance. This isn't just an IT problem; it's a barrier to medical innovation and patient empowerment.

Our Healthcare Blockchain Solutions
We offer a comprehensive suite of services to design, build, and deploy secure and compliant blockchain solutions tailored for the unique demands of clinical data sharing and healthcare interoperability.
Patient Consent Management Platforms
Empower patients with granular control over their health data. We build platforms where consent is recorded as an immutable transaction on the blockchain, providing an undeniable, auditable proof of who can access what data, for what purpose, and for how long. This transforms compliance from a liability into a trusted, transparent process.
- Create a single, verifiable source of truth for patient consent across multiple providers.
- Automate consent enforcement, reducing administrative overhead and human error.
- Enhance patient trust and engagement by providing them with direct control and visibility.
Clinical Trial Data Integrity Solutions
Ensure the end-to-end integrity of clinical trial data. By timestamping and hashing trial data on the blockchain, we create a tamper-evident log of every data point, from collection to submission. This eliminates data manipulation risks, streamlines audits, and accelerates the research-to-market pipeline for new therapies.
- Guarantee data provenance and immutability for regulatory submissions (e.g., to the FDA).
- Facilitate secure, multi-site data sharing between sponsors, CROs, and research centers.
- Reduce the time and cost of data reconciliation and auditing processes.
EMR/EHR Interoperability Layers
Solve the healthcare interoperability crisis without replacing legacy systems. We build a secure blockchain layer that acts as a "switchboard" for health data. Instead of storing PHI on-chain, the blockchain manages access permissions and pointers to data stored in existing, disparate EMRs, enabling secure, event-based data exchange based on patient consent.
- Enable seamless and secure data sharing between different hospitals and clinics.
- Maintain a complete, immutable audit trail of all cross-system data access.
- Reduce reliance on costly and complex Health Information Exchanges (HIEs).
Decentralized Health Identity (dHID) Systems
Create a single, universal, and patient-owned digital identity for healthcare. A dHID allows patients to securely authenticate themselves across any provider, pharmacy, or insurer without relying on multiple, insecure login credentials. This streamlines patient onboarding and reduces the risk of identity fraud.
- Eliminate duplicate medical records and patient matching errors.
- Provide patients with a portable, secure identity they control.
- Simplify and secure access to patient portals, telehealth platforms, and health apps.
Pharmaceutical Supply Chain Provenance
Combat counterfeit drugs and ensure regulatory compliance (e.g., DSCSA) with a blockchain-based track-and-trace solution. We create a shared, immutable ledger where every step of a drug's journey, from manufacturer to pharmacy, is recorded. This provides regulators, distributors, and patients with undeniable proof of authenticity and provenance.
- Create an immutable, real-time record of the drug supply chain.
- Prevent counterfeit medications from entering the legitimate supply chain.
- Automate compliance reporting and streamline recall management processes.
Our Path to Implementation: From Concept to Reality
We follow a structured, four-phase approach to de-risk your investment and ensure the final solution delivers tangible value to your organization and stakeholders.
1. Discovery & Strategic Alignment
We start by understanding your specific challenges, goals, and regulatory landscape. This phase includes stakeholder workshops, technical feasibility assessments, and the development of a detailed business case and ROI analysis to ensure complete alignment before any code is written.

The PoC focuses on testing the core blockchain mechanics and integration points within a controlled environment, providing tangible evidence of the technology's potential and informing the full-scale development plan.
3. Minimum Viable Product (MVP) & Pilot
We develop the core features of the platform and deploy it in a limited pilot program with real users. This agile approach allows us to gather critical feedback, refine the user experience, and demonstrate value quickly before committing to a full-scale rollout.
4. Enterprise Scaling & Support
Following a successful pilot, we scale the solution for enterprise-wide deployment. This includes full integration with legacy systems, robust security hardening, performance optimization, and ongoing support and maintenance to ensure the long-term success and evolution of your platform.
Success Stories in Healthcare Data Management
We deliver real-world solutions that solve critical challenges for our clients in the healthcare and life sciences sectors.
Ensuring Data Integrity for a Multi-National Pharmaceutical Clinical Trial
Client Overview
A top-20 global pharmaceutical company was struggling with data integrity and reconciliation across a multi-year, multi-site Phase III clinical trial for a new oncology drug. Data was collected across 50+ sites in different countries, leading to delays, high auditing costs, and concerns about the data's defensibility for regulatory submission.
"Errna's blockchain solution gave us a single source of truth for our trial data. The ability to prove data provenance to regulators was a game-changer, significantly reducing our submission preparation time."
- Aaron Welch, Director of Clinical Operations, Global Pharma Inc.
The Problem
The client needed an immutable, auditable system to track every data entry and modification from all clinical sites in real-time. They had to ensure that the final dataset submitted to the FDA and EMA was tamper-proof and that its entire lifecycle was transparently documented.
Our Solution
We designed and deployed a permissioned blockchain solution based on Hyperledger Fabric that integrated with their existing Electronic Data Capture (EDC) systems.
- Immutable Ledger: Each data submission from a clinical site was hashed and recorded as a transaction on the blockchain, creating a permanent, timestamped record.
- Role-Based Access: Smart contracts defined and enforced strict access controls, ensuring that only authorized personnel (e.g., site investigators, CRO monitors, sponsors) could view or interact with specific data sets.
- Automated Audit Trails: The solution generated a real-time, cryptographic audit trail, replacing manual and time-consuming auditing processes.
- Data Provenance Dashboard: We built a dashboard for regulators and internal auditors to visualize the entire lifecycle of any data point, from creation to final analysis.
Key Outcomes
Building a Secure HIE Network for a Regional Hospital System
Client Overview
A consortium of three independent regional hospitals wanted to create a Health Information Exchange (HIE) to share patient data for emergency care and specialist referrals. They were hampered by disparate EMR systems, patient data matching issues, and the high cost and complexity of traditional HIE vendors.
"Instead of a costly central database, Errna gave us a decentralized network built on trust. We can now share critical patient information securely and instantly, which has had a direct positive impact on patient outcomes in our emergency departments."
- Olivia Bishop, Chief Information Officer, Regional Health Alliance
The Problem
The alliance needed a way for an emergency room physician in one hospital to securely access a patient's critical records (allergies, medications) from another hospital in the network, but only with verified patient consent. The solution had to be secure, fast, and auditable.
Our Solution
We developed a blockchain-based interoperability layer that connected the hospitals' existing, FHIR-compliant EMR systems.
- Decentralized Data Pointers: No PHI was stored on the blockchain. Instead, the chain stored encrypted pointers to where data resided in each hospital's EMR.
- Consent Management via Smart Contract: Patient consent for data sharing was captured and managed via a smart contract, providing a transparent and irrevocable record.
- Master Patient Index on Blockchain: We created a decentralized Master Patient Index (MPI) to resolve identity matching errors between the different hospital systems.
- Secure API Gateway: A secure gateway allowed authorized EMR systems to query the blockchain for data location and access permissions before retrieving the data directly from the source hospital.
Key Outcomes
Creating a Patient-Centric Health Wallet for a MedTech Innovator
Client Overview
A well-funded MedTech startup aimed to launch a mobile application that would allow users to aggregate their health records from various providers into a single, secure "health wallet." Their business model depended on giving users absolute control and portability of their own data.
"Errna's team were true partners. They understood our vision for patient empowerment and had the deep technical expertise to build the secure, decentralized backend that makes our entire application possible."
- Carter Fleming, Founder & CEO, InnovateHealth Tech
The Problem
The startup needed a highly secure and decentralized backend that could manage user identities and data access permissions without the startup itself ever holding the keys to user data. This was critical for both user trust and regulatory compliance.
Our Solution
We built the backend infrastructure using a permissioned Ethereum blockchain and decentralized identity principles.
- Self-Sovereign Identity: Each user was issued a Decentralized Identifier (DID) stored on the blockchain, which they controlled with private keys stored securely on their mobile device.
- Data Access Tokens: When a user wanted to share data with a new doctor or app, they would authorize the request, which generated a short-lived, single-use data access token via a smart contract.
- Encrypted Data Storage: The actual health records were stored off-chain in an encrypted, decentralized storage solution (IPFS), with access keys managed by the user.
- FHIR API Integration: We built connectors to pull data from major EMRs using FHIR APIs, initiated and authorized only by the user through their health wallet.

Frequently Asked Questions
Clear answers to your most pressing questions about implementing blockchain in a clinical setting.
This is a critical distinction. We do not use public, permissionless blockchains like Bitcoin for healthcare data. We use private, permissioned blockchains (like Hyperledger Fabric) where only authorized participants can join. More importantly, we never store Protected Health Information (PHI) directly on the blockchain itself. The chain stores an immutable record of permissions, consent, and pointers to where the encrypted data resides in your existing, secure systems. This enhances HIPAA compliance by creating a perfect, unchangeable audit trail of all data access.
Yes. While the technology is still evolving, enterprise-grade platforms like Hyperledger Fabric and permissioned versions of Ethereum have been battle-tested for several years in demanding industries like finance and supply chain. The key is to move beyond the hype and apply the technology to solve specific, high-value problems like data integrity, consent management, and interoperability. Our approach focuses on these practical, proven use cases.
Timelines vary based on complexity, but we follow a phased approach. A typical engagement starts with a 4-6 week Discovery & Strategy phase. A Proof of Concept (PoC) can often be completed in the following 8-12 weeks. A pilot-ready Minimum Viable Product (MVP) usually takes 4-6 months to develop. Our focus is on delivering incremental value quickly to demonstrate ROI and build momentum.
Our solutions are designed as an augmentation layer, not a replacement. We use standard healthcare data protocols, primarily HL7 FHIR (Fast Healthcare Interoperability Resources), to communicate with your existing systems. We build secure API gateways that allow your EMR to query the blockchain for permissions and then access data from other systems. This preserves your investment in current infrastructure while unlocking new capabilities for secure data exchange.
For the initial build and deployment, our expert team handles the specialized blockchain development. Post-launch, we offer flexible engagement models. We can provide a fully managed service, handling all node maintenance, updates, and support. Alternatively, we can train your existing IT and DevOps teams to manage the network infrastructure, providing ongoing expert consultation as needed. The goal is to create a solution that fits your operational capabilities.
