Global Trade Finance Consortium
Industry: Banking & Finance
Client Overview: A consortium of five international banks sought to digitize and streamline the cumbersome, paper-based process of issuing and verifying letters of credit in international trade. The existing system was slow, prone to errors and fraud, and involved dozens of manual checks between multiple parties, leading to significant delays and operational costs.
"Errna didn't just build a platform; they helped us build a new standard for collaboration. The efficiency gains are just the beginning. We're now exploring new trade finance products that were impossible before."
- Head of Innovation, Lead Consortium Bank
The Problem
The lack of a single, trusted source of truth for trade documents (like bills of lading and inspection certificates) created massive inefficiencies. Each bank maintained its own ledger, requiring constant, costly reconciliation. The risk of document fraud was high, and settlement times could stretch for weeks.
Key Challenges
- Ensuring data confidentiality between competing banks.
- Integrating with diverse, legacy core banking systems.
- Designing a governance model acceptable to all members.
- Achieving regulatory compliance across multiple jurisdictions.
Our Solution
We architected and built a permissioned consortium blockchain on Hyperledger Fabric. The solution provided a shared, immutable ledger for all trade-related documents and events.
- Utilized Fabric's "Channels" to ensure that transaction details were only visible to the parties involved in a specific trade.
- Developed smart contracts to automate document verification and compliance checks against pre-defined rules, triggering payments automatically upon successful validation.

"The transparency this platform provides is game-changing for patient safety. Errna's expertise in both blockchain and healthcare regulations was invaluable. We now have a single, verifiable history for every package."
- Chief Compliance Officer, Global Pharma Inc.
The Problem
The fragmented nature of the pharmaceutical supply chain made it difficult to verify the authenticity and provenance of drugs at each handoff point. This created opportunities for counterfeit products to enter the supply chain, posing a significant risk to patient safety and causing financial losses.
Key Challenges
- Handling massive transaction volumes of serialized drug packages.
- Protecting commercially sensitive data like pricing and inventory levels.
- Ensuring the system was user-friendly for warehouse staff and pharmacists.
- Building a system that could be easily joined by new partners.
Our Solution
We developed a consortium blockchain using R3 Corda, chosen for its strong privacy features and focus on regulated industries. Each drug package was given a unique digital identity on the blockchain, which was updated at every step of its journey.

"We can now prove our commitment to sustainability. Errna helped us connect every stakeholder, from the small farmer to the end consumer, on a single, trusted platform. It has fundamentally changed how we tell our story."
- CEO, Fair Trade Coffee Collective
The Problem
Claims of "sustainability" and "fair trade" were difficult to verify, leading to consumer skepticism. The complex supply chain, involving numerous small farmers and intermediaries, made it nearly impossible to trace a bag of coffee back to its specific origin and verify the payments made at each stage.
Key Challenges
- Onboarding and training farmers in remote locations with limited technology access.
- Integrating with various certification bodies for fair trade and organic standards.
- Creating a simple way for consumers to access the provenance data.
- Ensuring the data recorded was accurate and tamper-proof.
Our Solution
We built a consortium platform on Quorum, providing a balance of privacy and transparency. The solution tracked each batch of coffee beans from the farm, through processing and export, to the final roasted product.
- Developed a simple, mobile-first application that allowed farmers to register their harvest on the blockchain, capturing key data like location, certifications, and quality metrics.
- Integrated with IoT sensors to automatically record data points like temperature and humidity during shipping, ensuring quality control.

Finding the Right Blockchain Model
Understanding the differences between blockchain types is key to choosing the right solution. A consortium blockchain offers a unique balance of control and decentralization ideal for B2B collaboration.
| Feature | Public Blockchain (e.g., Bitcoin, Ethereum) | Private Blockchain (e.g., a single company's internal ledger) | Consortium Blockchain (Our Expertise) |
|---|---|---|---|
| Participants | Anyone can join and participate (Permissionless). | Managed and controlled by a single organization (Permissioned). | Operated by a pre-selected group of trusted members (Permissioned). |
| Governance | Decentralized, often governed by community consensus and code. | Centralized, controlled by the owning organization. | Semi-decentralized, governed by the consortium members according to a pre-agreed framework. |
| Consensus | Requires computationally intensive mechanisms like Proof-of-Work. Can be slow. | Highly efficient, as trust is already established. Very fast. | Efficient mechanisms (e.g., IBFT, Raft) as members are known. Faster than public chains. |
| Data Privacy | All transactions are public and transparent to everyone. | Data is fully private and visible only within the organization. | Flexible. Data can be kept private to transacting parties while still being verifiable on the shared ledger. |
| Immutability | Very high, as changing the ledger requires immense computing power. | Lower, as the central organization could potentially alter the ledger. | High, as changing the ledger requires collusion among multiple member organizations. |
| Best Use Case | Public-facing applications, cryptocurrencies, censorship-resistant systems. | Internal process optimization, database management within a single entity. | B2B collaboration, supply chains, financial services, any multi-stakeholder business network. |

Frequently Asked Questions
A private blockchain is controlled by a single organization, making it centralized. A consortium blockchain is governed by a group of organizations. This semi-decentralized model fosters trust and collaboration between business partners who need a shared, immutable ledger without ceding control to a single entity.
This is a critical challenge we solve with our 'governance first' approach. We facilitate workshops to establish a formal governance framework that all members agree upon before development starts. This framework defines rules for data access, decision-making protocols, member voting rights, and dispute resolution, creating a fair and transparent system for all.
The choice depends entirely on your specific use case. Hyperledger Fabric is excellent for modularity and private data channels. R3 Corda is purpose-built for regulated industries like finance with a focus on peer-to-peer data sharing. Quorum offers Ethereum compatibility with enhanced privacy. We conduct a thorough analysis of your requirements to recommend and architect the best platform for your consortium.
We use several advanced techniques. Platforms like Hyperledger Fabric have "channels" or "private data collections" that allow a subset of members to transact privately. On Corda, data is shared strictly on a need-to-know basis between transacting parties. We combine these platform features with robust encryption to ensure confidentiality is maintained.
Timelines vary based on complexity, but we follow a phased approach. A Proof of Concept (PoC) can often be developed in 8-12 weeks. A Minimum Viable Product (MVP) for a pilot program might take 4-6 months. A full-scale, production-ready network rollout can take 9-12 months or more, including the crucial phases of governance design and member onboarding.
The cost is shared among members and depends on the network's complexity, the number of applications, and the scale of the infrastructure. We provide detailed, transparent pricing based on a thorough discovery process. The investment is weighed against the significant ROI from reduced operational costs, eliminated fraud, and automated processes.
