Trusted by Industry Leaders & Recognized for Excellence
From Data Silos to a Single Source of Truth
In a world of fragmented trust and data silos, enterprises lose millions to inefficiency, fraud, and compliance risks. Traditional databases can be manipulated, and multi-party transactions are slow and opaque, creating friction at every step.
Private blockchain development offers a revolutionary alternative: a shared, immutable ledger that provides cryptographic certainty. It's not about public cryptocurrencies; it's about creating a secure, permissioned environment where your business and its partners can transact with absolute confidence and transparency.
At Errna, we architect and deploy enterprise-grade private blockchains that solve these core challenges, transforming your operations from the inside out.

The Problem
The client was struggling with slow, expensive, and opaque cross-border payment settlements that took 3-5 business days, involved multiple intermediaries, and were prone to errors and high FX fees.
Key Challenges
- Lack of real-time transaction visibility.
- High operational costs due to manual reconciliation.
- Counterparty risk and trust deficits between financial institutions.
- Complex multi-currency compliance and reporting.
Our Solution
We developed a private, permissioned blockchain based on Hyperledger Fabric, creating a shared, immutable ledger for all participating financial institutions.
- Created a digital representation (token) of fiat currencies for instant transfer.
- Implemented smart contracts to automate compliance checks and fee calculations.
- Provided a real-time dashboard for all parties to track the status of funds.
- Integrated with existing core banking systems via secure APIs for seamless operation.
The Problem
The client, a consortium of growers and retailers, faced challenges with food fraud, inefficient recall processes, and an inability to verify claims of organic and fair-trade sourcing.
Key Challenges
- Fragmented data across dozens of independent stakeholders.
- Days or weeks required to trace the source of a contamination.
- Prevalence of counterfeit products damaging brand reputation.
- Inability to provide consumers with verifiable product journey information.
Our Solution
We built a consortium blockchain allowing farmers, distributors, and retailers to record every step of the food's journey on a shared, tamper-proof ledger.
- Developed mobile dApps for easy data entry at each stage (harvest, transport, storage).
- Integrated IoT sensors to automatically record temperature and humidity data.
- Created a QR code system for consumers to scan and view the product's full history.
- Implemented smart contracts to automatically trigger alerts for compliance deviations.
The Problem
A network of hospitals and clinics needed to share patient records for better care coordination but was hampered by data silos, interoperability issues, and strict HIPAA privacy regulations.
Key Challenges
- Risk of unauthorized access to sensitive patient health information (PHI).
- Inability for patients to control who sees their medical history.
- Time-consuming and manual process for requesting and receiving records.
- Lack of a single, unified view of a patient's medical journey.
Our Solution
We engineered a HIPAA-compliant private blockchain where patient data itself is stored off-chain, while access permissions and a hash of the records are logged immutably on-chain.
- Developed a patient-centric consent model using smart contracts, giving patients control.
- Created a secure API for EMR/EHR systems to interact with the blockchain network.
- Built an immutable audit trail of every single access request and data view.
- Utilized Decentralized Identifiers (DIDs) to manage identities of patients and providers securely.

Frequently Asked Questions
Clear, concise answers to the most common questions about private blockchain development.
A public blockchain (like Bitcoin or Ethereum) is open for anyone to join, view transactions, and participate in the consensus process. A private blockchain is permissioned, meaning participants must be invited and authenticated. This allows organizations to control who can access the network and what data they can see, making it ideal for enterprise use cases where privacy and control are essential.
While a database is excellent for centralized data management, a private blockchain excels where multiple, distinct organizations need to share data and transact without a central intermediary. Its key advantages are: Immutability (data cannot be altered or deleted), Decentralization (no single point of failure), and Cryptographic Trust (transactions are secured and verified by the network itself), creating a single, shared source of truth that all parties can rely on.
We use several techniques. First, the network is permissioned, so only authorized parties can join. Second, we can create "channels" or "private data collections" (depending on the platform) so that specific participants can transact privately without the entire network seeing the data. Finally, we employ advanced encryption and can even use techniques like zero-knowledge proofs to verify a transaction happened without revealing the underlying data.
The timeline varies based on complexity. A Proof of Concept (PoC) can often be developed in 4-8 weeks. A full-scale, production-ready enterprise solution can take anywhere from 4 to 9 months. Our structured process, starting with a discovery phase, ensures we provide a detailed and realistic timeline upfront.
Ongoing maintenance is crucial for a healthy network. It includes proactive network monitoring, managing node performance, applying security patches and platform updates, providing user support, and planning for future scalability. Our managed services ensure your blockchain remains secure, efficient, and aligned with your evolving business needs.
