Consortium Blockchain Development: Build Your Shared System of Trust
Create a single, immutable source of truth for your business ecosystem.
Securely automate multi-party workflows, enhance transparency, and unlock new collaborative models.
Your business doesn't operate in a vacuum. You rely on a complex network of suppliers, partners, and customers. But coordinating with them often means navigating disparate systems, endless reconciliations, and a fundamental lack of trust in shared data. A traditional centralized database won't solve this; it just puts one party in control. A public blockchain is too open. The solution is a consortium blockchain: a private, permissioned network governed by a pre-selected group of participants. It provides the "trustless" security of a blockchain with the control and privacy your business ecosystem needs. We build these collaborative platforms, turning your network's biggest friction points into your greatest competitive advantage.

Enhancing Traceability in the Global Coffee Supply Chain
Client Overview: A consortium of international coffee growers, distributors, and large-scale retailers sought to create a transparent and ethical supply chain. Their goal was to provide consumers with verifiable proof of origin and fair-trade practices while streamlining logistics and reducing instances of fraud (e.g., counterfeit premium beans).
They faced significant challenges with paper-based documentation, data silos between partners, and long delays in verifying shipments at various checkpoints, leading to spoilage and financial losses.
Key Challenges:
- Lack of a single, trusted source of truth for product journey.
- High administrative overhead from manual tracking and reconciliation.
- Inability to quickly identify the source of contamination or quality issues.
- Difficulty in proving fair-trade and organic certifications to consumers.
Our Solution:
We developed a consortium blockchain on Hyperledger Fabric, creating an immutable, shared ledger for all participants. Each step, from harvesting and processing to shipping and retail, was recorded as a transaction on the blockchain.
- Integrated IoT sensors on shipping containers to automatically record temperature and location data on the chain.
- Developed a QR-code system for product packaging, allowing consumers to scan and view the coffee's entire journey.
- Created role-based dApps for growers, customs officials, and retailers to securely input and view relevant data.
- Implemented smart contracts to automate payments upon successful verification of delivery and quality standards.
"The transparency this platform provides is revolutionary. We've cut our audit times by more than half and can now offer our customers a level of product provenance that was previously impossible. Errna was the right partner to navigate the complexities of building a multi-stakeholder solution."
Positive Outcomes:
Streamlining Multi-Party Trade Finance
Client Overview: A group of regional banks, importers, and exporters aimed to digitize and accelerate the cumbersome process of issuing and settling letters of credit (LCs). The existing system relied on the physical exchange of documents, leading to processing times of weeks, high operational costs, and a significant risk of fraud and human error.
The consortium needed a shared platform where all parties could interact with a single, digital version of the trade documents in real-time, while maintaining strict confidentiality and adhering to international trade regulations.
Key Challenges:
- Average LC settlement time of 15-20 days.
- High risk of document fraud and discrepancies.
- Lack of real-time visibility into the status of a trade for all parties.
- Expensive and inefficient manual document verification processes.
Our Solution:
We built a trade finance platform using R3 Corda, which is specifically designed for complex transactions between regulated institutions. The solution digitized the entire LC lifecycle, from application to settlement, on a shared, permissioned ledger.
- Created digital versions of key trade documents (Bill of Lading, invoice, etc.) as "states" on the Corda network.
- Developed smart contracts to automatically verify document consistency and trigger actions when conditions were met (e.g., release of funds upon proof of shipment).
- Designed a confidential data-sharing model where only the parties involved in a specific trade could see its details.
- Integrated with existing bank systems and SWIFT for seamless payment processing.
"Errna's expertise in Corda was instrumental. They understood the nuances of financial regulations and built a platform that not only reduced our processing time to mere hours but also significantly lowered our risk exposure. This is the future of trade finance."
Positive Outcomes:
Securing Clinical Trial Data Exchange
Client Overview: A consortium of pharmaceutical companies, clinical research organizations (CROs), and hospitals needed a secure and auditable way to share sensitive patient data during multi-site clinical trials. The primary challenges were ensuring data integrity, maintaining patient privacy (HIPAA compliance), and giving regulators a transparent view of the trial's progress without compromising confidentiality.
Data was fragmented across different systems, making it difficult to aggregate and analyze, and creating a significant compliance burden to ensure that data access was properly logged and authorized.
Key Challenges:
- Risk of data tampering or unauthorized access to patient records.
- Ensuring HIPAA compliance across multiple, independent organizations.
- Lack of an immutable, time-stamped audit trail for regulatory reporting.
- Inefficient processes for gaining patient consent and managing data permissions.
Our Solution:
We engineered a HIPAA-compliant data exchange platform using an Ethereum-based Quorum network. The solution focused on managing patient consent and providing a verifiable log of all data interactions.
- Patient data itself was stored off-chain in the members' existing secure databases. The blockchain was used to store hashes of the data and manage access permissions.
- Developed a "patient consent" smart contract, allowing patients to grant or revoke access to their data for specific research purposes, with every action logged immutably.
- Created a permissioned system where researchers could request access to anonymized data sets, and access was only granted after cryptographic verification of their credentials and the patient's consent.
- Built a dedicated portal for regulators to view an immutable audit trail of all data access events, dramatically simplifying compliance checks.
"The ability to provide regulators with an unchangeable audit log is a game-changer for us. Errna delivered a solution that balanced the critical needs of data sharing for research with the absolute requirement for patient privacy. Their understanding of both blockchain and healthcare compliance was exceptional."

Frequently Asked Questions
Clear answers to common questions about building and participating in a consortium blockchain.
A private blockchain is controlled by a single organization. A consortium blockchain is governed by a group of pre-approved organizations. The key difference is governance: a consortium is decentralized among its members, fostering greater trust and collaboration than a single-entity-controlled private chain.
We use several techniques. Platforms like Hyperledger Fabric have "channels" that allow a subset of members to transact privately. R3 Corda is designed for peer-to-peer transactions, so data is only shared on a need-to-know basis. We also employ data encryption and zero-knowledge proofs to allow for verification without revealing underlying sensitive data.
The timeline varies based on complexity. A Proof of Concept (PoC) can be developed in 4-8 weeks. A full production-ready network with multiple integrations typically takes 6-12 months. Our phased approach ensures you see value early and can build momentum.
Ongoing costs typically include infrastructure hosting (for nodes), network monitoring, software maintenance and upgrades, and governance support. We offer flexible managed service plans that bundle these costs into a predictable monthly fee, shared among the consortium members.
This is defined in the governance model. Typically, a new member must be proposed and then voted on by the existing members. Once approved, our team manages the technical onboarding process, which includes deploying their node, issuing credentials, and integrating them into the network's permissioned structure.
