Client Overview
A leading pharmaceutical company was struggling with data inconsistencies and slow patient recruitment for a complex, multi-site Phase III oncology trial. Data from various clinical sites arrived in different formats, leading to significant delays and costs in data cleaning and reconciliation. They needed a single source of truth to ensure data integrity and accelerate the trial timeline.
"Errna's blockchain solution transformed our clinical trial operations. The immutable audit trail gave us complete confidence in our data, and the streamlined consent process helped us enroll patients faster than ever. It was a game-changer for our research pipeline."
- Dr. Alisha Vance, Head of Clinical Operations, Global Pharma Inc.The Challenge
The client faced four critical issues: lack of real-time data visibility across sites, inconsistent data entry practices, a cumbersome and paper-based patient consent process, and difficulties in proving data provenance to regulatory bodies.
Our Solution
Errna developed a consortium blockchain platform connecting the pharma sponsor with all participating clinical sites. The solution focused on:
- Decentralized Identity & Consent: Patients were issued a digital identity to manage their consent for data usage in real-time via a simple mobile app.
- Smart Contract Automation: Smart contracts were used to automatically verify that data submissions adhered to the clinical trial protocol, rejecting non-compliant entries.
- Immutable Data Logging: While the PHI remained in the sites' secure systems, hashes of the data and all access events were logged on the blockchain, creating a tamper-proof audit trail.
- FHIR-Based Integration: We built API gateways using the HL7 FHIR standard to ensure seamless data exchange between the sites' EMRs and the blockchain network.
Client Overview
A consortium of regional hospitals and clinics aimed to establish a Health Information Exchange (HIE) to improve care coordination. However, they were wary of the high costs, security risks, and competitive data-hoarding issues associated with traditional, centralized HIE models. They needed a decentralized approach that allowed participants to maintain control over their data while enabling secure, permissioned sharing.
"We wanted to build an HIE based on trust and collaboration, not control. Errna's decentralized blockchain model was the perfect fit. We've eliminated data silos and improved patient safety, all while giving each member hospital full sovereignty over their data."
- David Miller, CIO, Unity Health SystemThe Challenge
The key challenges were establishing a trusted and accurate Master Patient Index (MPI) across disparate systems, ensuring robust security without a central point of failure, motivating competing hospitals to share data, and managing complex patient consent for data exchange.
Our Solution
We implemented a permissioned blockchain network to act as the HIE's "traffic controller" and trust layer:
- Blockchain as Master Patient Index: The blockchain was used to create a decentralized MPI, linking patient records across institutions without creating a centralized database of PHI.
- Peer-to-Peer Data Exchange: When a physician at one hospital needed a patient's record from another, the request and consent verification were handled via the blockchain, but the actual data was exchanged directly and securely between the two institutions.
- Tokenized Incentives: A utility token system was introduced to reward institutions for actively and accurately sharing data, overcoming competitive friction.
- Granular Access Control: Smart contracts enforced rules about who could access what data, for what purpose, and for how long, based on patient consent and the provider's role.
Client Overview
A cutting-edge biotech firm wanted to create a marketplace for genomic data to accelerate research in personalized medicine. Their vision was to empower individuals to securely share their anonymized genetic data with researchers and be compensated for its use. They needed a platform that could guarantee privacy, security, and transparent value exchange.
"Errna helped us build more than a platform; they helped us build a community founded on trust. Patients feel secure sharing their data because they have complete control and transparency. This has unlocked a treasure trove of information for researchers."
- Dr. Elena Petrova, Founder & CEO, GenoLife AnalyticsThe Challenge
The primary hurdles were earning patient trust to share highly sensitive genomic data, ensuring data remained anonymized yet valuable for research, creating a fair and automated system for compensating data donors, and providing researchers with a simple, secure way to query and access data.
Our Solution
We engineered a Web3 marketplace powered by blockchain and privacy-preserving technologies:
- Self-Sovereign Identity (SSI): Each patient was given an SSI wallet to control their genomic data profile and manage sharing permissions without revealing their real-world identity.
- Zero-Knowledge Proofs: Researchers could query the dataset to see if it contained relevant data (e.g., "how many participants have marker X?") without accessing the raw data itself, preserving privacy until a purchase was made.
- NFTs for Data Licenses: When a researcher purchased access to a dataset, a non-fungible token (NFT) representing a time-bound, purpose-specific data license was issued.
- Automated Micropayments: Smart contracts automatically distributed royalty payments in stablecoins to the wallets of all patients whose data was included in the purchased set.

Frequently Asked Questions
Clear answers to common questions about implementing blockchain for clinical data sharing.
No, absolutely not. Storing Protected Health Information (PHI) directly on a blockchain is a violation of HIPAA and other privacy regulations. Our "privacy-by-design" approach keeps all sensitive data in your existing, secure, off-chain storage (like your EMR database). The blockchain is used to manage consent and create an immutable, auditable log of data access—essentially, it records who accessed what data, when, and with what permission, without ever holding the data itself.
We prioritize seamless integration. Our solutions act as a secure data exchange layer that sits on top of your existing infrastructure. We use industry-standard protocols, primarily HL7 FHIR (Fast Healthcare Interoperability Resources), to build APIs that allow your EMR/EHR to communicate with the blockchain network. This means minimal disruption to your clinical workflows and no need to "rip and replace" your core systems.
This is a common misconception based on public cryptocurrencies like Bitcoin. We use private or consortium (permissioned) blockchains like Hyperledger Fabric, which are designed for enterprise use. These networks use high-speed consensus mechanisms (like Raft or IBFT) and do not involve mining. They can handle thousands of transactions per second, which is more than sufficient for clinical data exchange and access logging in real-time.
This varies greatly depending on the complexity of the use case. We always start with a 6-8 week Proof-of-Concept (POC) to validate the technology and demonstrate ROI for a specific, high-impact problem. A full production-level implementation can range from 6 to 12 months. We provide transparent, milestone-based pricing after an initial consultation to understand your unique requirements.
This is an excellent question. While the blockchain ledger itself is immutable (you can't delete a past record), this doesn't mean errors can't be corrected. The correct process is to append a new transaction that rectifies the previous one. For example, a new entry would be made stating, "Transaction X is incorrect; the correct value is Y." This creates a fully transparent and auditable history of all changes, which is actually a major advantage over traditional databases where corrections can be made without a trace.
