Our Proven Success in Action
We deliver results, not just reports. Explore how we've helped businesses like yours leverage IoT and blockchain to achieve remarkable outcomes.
The Problem
The client faced significant financial losses and regulatory risk due to breaks in the cold chain. Proving continuous temperature compliance to regulators and customers was a manual, paper-based process prone to error and fraud.
Key Challenges
- Inability to get real-time alerts on temperature deviations.
- Lack of a single, trusted source of truth for all stakeholders.
- High administrative costs for manual compliance reporting.
- Disputes with clients over shipment integrity.
Our Solution
We developed a private blockchain solution integrated with cellular-enabled temperature sensors in their shipping containers. Every 15 minutes, temperature and location data was cryptographically signed and recorded on an immutable ledger.
- Deployed IoT sensors that anchored data to a Hyperledger Fabric blockchain.
- Created smart contracts to automatically trigger alerts if temperatures went outside a predefined range.
- Built a permissioned dashboard for clients, regulators, and internal teams to view the immutable audit trail.
- Integrated the blockchain data with their existing ERP for automated compliance documentation.

The Problem
The client needed to provide absolute proof of quality and adherence to strict manufacturing tolerances for every component. Their existing quality control process was robust but lacked a single, immutable record that could be easily shared and verified by their customers (major aircraft manufacturers).
Key Challenges
- Complex and fragmented data from various CNC machines and sensors.
- Risk of data tampering in centralized quality databases.
- Time-consuming process to compile audit reports for clients.
- Difficulty in quickly tracing the root cause of a defect.
Our Solution
We implemented a consortium blockchain where the client and their key customers were participants. We integrated IoT sensors on their manufacturing line to capture critical data points (e.g., machine calibration, material batch, final measurements) and record them on the shared ledger.
- Connected PLC and sensor data from the factory floor to the blockchain via a secure gateway.
- Created a "digital twin" for each component, with its entire production history stored immutably.
- Developed smart contracts to automatically flag any deviation from specified tolerances in real-time.
- Provided customers with a secure portal to scan a component's QR code and view its full, verified history.

The Problem
The cooperative's parametric crop insurance policies (which pay out based on specific events like frost or drought) were inefficient. The claims process required manual verification by adjusters, leading to long delays in payouts and disputes over the accuracy of weather data.
Key Challenges
- Dependence on third-party, often disputed, weather station data.
- Slow and expensive manual claims adjustment process.
- Lack of trust between farmers and the insurance provider.
- Delayed payouts impacting farmers' cash flow.
Our Solution
We created a decentralized insurance platform using a public blockchain and integrated it with a network of on-farm IoT sensors (measuring soil moisture, temperature, etc.) and a trusted weather data oracle.
- Deployed hundreds of LoRaWAN-based sensors across the cooperative's farms.
- Developed a smart contract representing the insurance policy, with predefined payout conditions.
- Used a Chainlink oracle to feed verified weather data to the smart contract.
- When sensor and oracle data met the payout conditions (e.g., 3 consecutive nights below freezing), the smart contract automatically executed the insurance payment to the cooperative's wallet.

Frequently Asked Questions
Have questions? We have answers. Here are some of the most common inquiries we receive about our IoT and blockchain integration services.
Blockchain adds multiple layers of security. First, data is cryptographically hashed and linked in a chain, making it immutable; any change to a past record would break the entire chain and be instantly detected. Second, in a decentralized network, the ledger is distributed across many computers, so there is no single point of failure or attack. Finally, we can implement decentralized identities for devices, preventing unauthorized devices from sending data to the network.
Absolutely. Scalability is a primary consideration in our architecture design. We don't just use standard public blockchains like Ethereum for high-throughput IoT. We leverage solutions like private/consortium blockchains (e.g., Hyperledger Fabric) which are designed for enterprise performance, as well as Layer-2 scaling solutions. We also architect data handling so that only critical data points or hashes are stored on-chain, while the bulk data can be stored off-chain, ensuring efficiency and low cost.
The cost and timeline vary significantly based on the project's complexity, the number of integrations, and the scale of the device network. A typical project starts with a 4-6 week Discovery and PoC phase to validate the concept and define the scope. A full-scale implementation can range from 4 to 9 months. We provide a detailed, transparent quote after the initial discovery phase. Our goal is to deliver a solution with a clear and compelling ROI.
Our team are integration specialists. For hardware, we can work with your existing IoT devices or recommend new ones, developing custom firmware or using gateways to securely connect them to the blockchain. For software, we build robust REST APIs and middleware to create a secure data pipeline between the blockchain and your existing enterprise systems like ERP, SCM, or CRM, ensuring a seamless flow of information.
There's no single "best" platform; the right choice depends entirely on the use case. For enterprise applications requiring high performance, privacy, and permissioned access, we often recommend Hyperledger Fabric or R3 Corda. For applications that benefit from a public, decentralized ecosystem, we might use Ethereum with a Layer-2 scaling solution like Polygon. Part of our initial consulting is to analyze your needs and recommend the optimal platform for your specific goals.
